Part of the Ultimate Home Detox™ Unpacked Thursday series—light, inspiring insights from Sophia's personal journey in Practical Nontoxic Living™. Did you know that the way you cook can create cancer-causing compounds in your food? In this episode of Practical Nontoxic Living, Sophia Ruan Gushée highlights the hidden dangers of high-heat cooking methods like frying, grilling, and roasting—and how they can lead to the formation of toxic compounds such as heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs). Whether you're detoxing your home for fertility, cancer recovery, chronic illness, or general wellness, this episode offers simple, science-backed tips to help you: Reduce exposure to carcinogenic cooking byproducts Choose safer cooking oils and methods Make small, impactful changes in your daily cooking routine Improve your family's long-term health—without sacrificing flavor Perfect for health-conscious cooks, detox enthusiasts, and anyone looking to make their kitchen a cleaner, safer space.
These dangerous ingredients are found in the #1 most dangerous meal. Can you guess what it is?1. Polycyclic aromatic hydrocarbons (PAHs) are byproducts created when you cook, char, or smoke something. Cooking at high temperatures creates these compounds, which have the potential to alter or mutate your DNA and can trigger cancer of the stomach or colon.2. When you combine sugar with protein, you create AGEs (advanced glycation end products). These sticky proteins found in foods like barbequed meat can cause advanced aging, inflammation, diabetes, Alzheimer's, and other chronic diseases. 3. Sodium nitrate is found in processed meat like bacon and ham. When heated, it turns into a carcinogen, which can trigger cancer.4. Residue from the weed killer Roundup Ready is often found in GMO foods such as soy, corn, canola, and cottonseed. Roundup Ready contains the ingredient glyphosate, which is considered a carcinogen by the World Health Organization. Glyphosate also disrupts the microbiome.5. Caramel coloring, which is used in barbeque sauces and sodas, produces a carcinogenic byproduct called 4-MEI. 6. Aluminum can leach into the brain, increasing your risk for Alzheimer's and other neurodegenerative diseases. 7. Potassium bromate is found in barbeque sauces and is often used to increase fluffiness in bread products. This ingredient has been banned in 60 countries, but it's not banned in the U.S.The most dangerous meal includes barbequed meat that's been grilled, covered in barbeque sauce, and typically cooked on or covered with aluminum foil. Many types of meat served at barbeques contain nitrates and are often wrapped in a bun or served with bread. This meal is usually served with a soda in an aluminum can or plastic bottle and served on a styrofoam plate.
A disturbing report from the University of Johannesburg has uncovered alarming levels of cancer-causing chemicals in the Klip River, a vital water source in Gauteng. The study reveals high concentrations of polycyclic aromatic hydrocarbons, or PAHs, which pose a significant threat to aquatic life, livestock, and human health. To elaborate further on the research, Elvis Presslin spoke to Dr. Mathapelo Seopela, Lecturer and Researcher at the Department of Chemical Sciences at the University of Johannesburg

Host Dr. Davide Soldato and his guests Dr. Ann Wu and Dr. Alexa White discuss the article "Air Pollution and Breast Cancer Incidence in the Multiethnic Cohort Study" and the editorial "Growing Evidence for the Role of Air Pollution in Breast Cancer Development" TRANSCRIPT The guests on this podcast episode have no disclosures to declare. Dr. Davide Soldato: Hello and welcome to JCO After Hours, the podcast where we sit down with authors from some of the latest articles published in the Journal of Clinical Oncology. I am your host, Dr. Davide Soldato, Medical Oncologist at Ospedale San Martino in Genoa, Italy. Today, we are joined by JCO authors Dr. Anna Wu and Dr. Alexander White. Dr. Wu is a professor of Population and Public Health Sciences at the Keck School of Medicine of UCS, while Dr. White is an investigator in the Epidemiology branch of the Environment and Cancer Epidemiology Group at the National Institute of Health. Today, we will be discussing the article titled, “Air Pollution and Breast Cancer Incidence in the Multiethnic Cohort Study,” and the accompanying editorial. So, thank you for speaking with us, Dr. Wu, Dr. White. Dr. Anna Wu: Thank you for having us. Dr. Alexandra White: Yes, thank you so much for the invitation to be here. Dr. Davide Soldato: So before going in depth about the results of the study that was published in the JCO, I was wondering if you could give us like a brief introduction and a little bit of background about what was known about air pollution as a risk factor for breast cancer and what was the evidence before this study was conducted. Dr. Alexandra White: Okay. I can start with that question. So, there's been research for decades looking at the relationship between air pollution and breast cancer. And it's been a really challenging question to address for a number of reasons. One being that it can be really difficult to assess exposure to air pollution and many previous studies have had really limited information on people's residences over time. But in general, what we thought leading up to this study was that evidence was most consistent that exposure to traffic related pollutants such as nitrogen dioxide was more consistently related to a higher risk of breast cancer. The evidence for fine particulate matter or PM2.5 was less consistent. More recently, there have been a few large, well conducted studies that have supported a positive association. This new study in the multiethnic cohort led by Dr. Wu is really important because it really demonstrated that, in this large study of over 50,000 women in California, that they also do see an association with PM2.5. Dr. Davide Soldato: Thank you very much for the introduction. So, Dr. Wu, we just want to hear a little bit more about the results. So, what was the association that was observed for PM2.5? And specifically, the study that you ran was focused on a very diverse population, a multiethnic cohort, and so I was wondering if you observed any type of differences when you consider the different populations that were included in your study. And if you could also give us a little bit of what was the composition of the women that were enrolled in this cohort. Dr. Anna Wu: Thank you for the question. So, the multiethnic cohort study is a cohort of over 200,000 individuals who were enrolled when they lived in Hawaii or California. For the air pollution studies that we've been conducting, we have focused on primarily the California participants. And in this instance for the breast cancer study, it was based on roughly 56,000 individuals out of- there were about 100,000 because half of them were men and they were not included. Of the California participants, 75% of them were African Americans or Latinos and they were self-identified as these racial ethnic groups when they enrolled in the study. And this was a particularly important consideration for us because in most of the studies that have been published so far on-air pollution and breast cancer, as well as other cancer sites, most of those studies were conducted among whites in the US or whites in Europe. And even if they included non-white populations, the numbers tend to be small so that they were not able to conduct racial ethnic specific analysis. So, we were particularly interested in examining these other racial ethnic groups because we know from other studies that racial ethnic minority groups tend to live in communities of low socioeconomic status and those communities also tend to have higher levels of various types of environmental pollutants. And so, it was important for us to actually try to tease apart these various interrelated factors. So, what we found was that per 10 micrograms per cubic meter, we had a 28% increased risk overall in all participants combined that meet across the racial ethnic groups. We actually did not see any differences or significant differences in the hazard ratios by race ethnicity and they were in general quite compatible with each other. But we did see a stronger finding among the white participants in our study. Dr. Davide Soldato: Thank you, a lot, Dr. Wu. So, I think it's very interesting the fact that in the end you observed that air pollution is a significant risk factor across all the ethnicities that were included in the study. But I think that one very strong point of the manuscript and one very strong point of the analysis was that in the end you also corrected for a series of different factors because we know that the incidence of breast cancer can be modified, for example, by familial history or BMI or smoking habits or also alcohol consumption. And a lot of these risk factors were included in your analysis. And so, I was wondering if you could tell us a little bit whether you observed any significant differences when you observed or included also these risk factors in your analysis, or whether the association for air pollution as a risk factor stands even when we consider all of these other elements. Dr. Anna Wu: Yes. So, we considered all the well-established breast cancer risk factors. And in this situation, we were particularly interested in considering smoking, alcohol intake, use of menopausal hormones, history of diabetes, body mass index, family history, as well as physical activity, because many of these risk factors, such as, for example, diabetes and body mass index, they are risk factors for breast cancer, and air pollution, have also been found to increase risk of these factors. So, in our analysis, we first adjusted for all of these potential confounders in a mutually adjusted manner, so all of them were considered. In addition, we also conducted stratify analysis. So as an example, we stratified the analysis to examine whether the hazard ratio associated with PM2.5 provided comparable risk estimate or hazard ratio estimates for never smokers, former smokers, and current smokers. Although we did not see significant heterogeneity by these various subgroups, we did see a significantly stronger effect of PM2.5 among individuals who did not have a family history of breast cancer. Interestingly, our finding was also stronger among individuals who were never smokers and light alcohol drinkers, even though the results were not significantly different. So, we surmised that maybe individuals who already had a high risk because of other established risk factors for breast cancer, we were less likely to be able to observe the effect of air pollution. But it's important to note that other studies, such as the ones that Dr. White has conducted, have also looked at various subgroups, and I think part of the limitation that all of us have is that once you subdivide the study population, even if you start out with a large sample size, often the sample size gets cut in half or a third. And so, we still lack the statistical power to be able to observe significant differences. But I think it is important to note that, in fact, the hazard ratio estimates are actually quite comparable, but we did see a hint of stronger effects among never smokers, and people who were light alcohol drinkers. So, I think this is an area that we certainly need to continue to investigate since there are other subgroups, such as menopausal status, such as hormone receptor status of breast cancer, that we need to consider in future studies. There's still a lot of work we need to do to sort this out, to actually figure out who are the women who are the most susceptible to the exposures. Dr. Davide Soldato: Dr. White, I would really love a comment from you on this specific area and specifically on what still needs to be done. And related to this, a question actually, for both of you, because I think that from a methodological point of view, there is a lot of work that goes into deciding how we are going to assess the exposure to air pollution. So which type of data are we going to use? Which type of data are we currently using in the epidemiological studies that have been conducted and in the one that we are discussing right now in JCO? And what are the caveats for this data that we are using? Meaning, I think that we use mostly residential addresses, which means that we are looking at the exposure where people actually live, which might not be the place where they spend most of their time. For example, if someone is working, maybe they could be more exposed and have higher exposure when they are at work compared to when they are at home. So, I was wondering if you could give us a little bit of an overview as to what is the methodological standard of care right now in terms of this analysis and what can we do better to refine and understand this specific factor as Dr. Wu was mentioning? Dr. Alexandra White: Yeah, so I'm happy to take a first stab at that question. So, I think it's important to note just how far we've come. I think even a few years ago, air pollution was really not considered a risk factor for breast cancer. And a lot of the work that we've been doing and others have really moved this forward in terms of understanding this as a risk factor. And as I mentioned earlier, there have been a lot of challenges in exposure assessment. And to get to your question, I think that our studies in general are doing better at looking at exposure over more years, residences, more time. We know that cancer takes time to develop, and we can't rely on just a single snapshot of exposure. But as you mentioned, almost all of the studies published have really exclusively focused on residential estimates of exposure. And so, there's a real need to understand the exposures that people are experiencing in other aspects of their life, from their commute to their jobs, to really capture that totality of exposure. And then I think one of the points that Dr. Wu was alluding to as well as we know that breast cancer is a very heterogeneous disease, so risk factors for breast cancer vary by tumor subtypes, by menopausal status at diagnosis. And a lot of studies have really focused on considering breast cancer as a combined outcome, and that might be missing some really important signals where we might have a stronger effect for certain subtypes due to the fact that there's different biologic pathways that are underlying these subtypes or by menopausal status. And so having large study populations where, as we discussed earlier, would really give us the power to look among these smaller groups of women who might be more susceptible and those with younger women, we know that incidence of cancer is rising in young people, and we need to understand the risk factors for that. And most of our studies are really focused on older individuals, so I think that's one important gap, as well as having the power to really look at different differences by tumor subtypes. Dr. Davide Soldato: I think it's very interesting, and I think one point both of you made in the original article and in the accompanying editorial is also the fact that we tend to look at these risk factors in people who are actually aged, while we maybe should be looking at this in an earlier phase of development and potentially during puberty. Do you think that we should design studies that are more focused on this population even though I think that they will take a lot of time to produce significant results? Dr. Alexandra White: Yeah. I think that it is really important to consider how exposure during early life is related to breast cancer risk. We know that exposures during pregnancy or even as early as during puberty might be particularly relevant for breast cancer. And I think a lot of our studies have really been up against the challenge of the fact that exposure monitoring for air pollution really didn't start until the 1990s. And so, it's challenging, especially for these older cohorts, to get back at that time period that might be relevant. But I think that's something that definitely newer cohorts are going to be able to address, and I think it's going to be really important, and also will give us some clues to better understand the important windows of exposure, but also that might provide clues for the biologic pathways as well that are relevant. Dr. Davide Soldato: And just a related question, because I'm not aware of this, but are there right now cohorts that are specifically looking at this in the US or in other parts of the world? If you are aware of that, of course. Dr. Alexandra White: There have been some cohorts that have focused on exposure during these hypothesized windows of susceptibility, but I don't think they've been able to follow those women long enough to develop breast cancer. One of the things that we're working on in the sister study is trying to expand our assessment of air pollution exposure back in time to try to get at these earlier windows of exposure. So, I'm hoping that it's something we'll be able to comment on and at least for some of the women in our cohort who are younger. But I don't know, Dr. Wu, if you're familiar with any other populations that are doing this now? Dr. Anna Wu: Well, NCI funded several new cohorts in the last couple years that are really focused on trying to get a much more refined exposure assessment. So, I know colleagues at University of Michigan that are peers and also Dr. Wei Zheng at Vanderbilt, they are putting together newer cohorts that are younger and also trying to include a range of exposure, not just air pollution, but really environmental exposures. Those cohorts I think have the potential in the future to try to address some of these questions, but again, it will take at least another number of years before there are a sufficient number of endpoints so that they can actually do these types of studies. Another possibility is that there are a number of big cohort studies in Asia. The age of diagnosis tends to be earlier in Asia. I know that investigators in China are very interested and concerned with the air pollution effects in China. I think there are potentials that in other countries where the age of breast cancer diagnosis is actually younger than in the US and if they establish in a manner that allows them to assess air pollution that they may have opportunities. And I think the other way to try to address this question, whether there are studies where you can actually tap into either biomarkers or pathology samples so you won't be actually studying air pollution in a large population, but you're actually narrowing it down to try to see if you see any signals in a way that would give you some additional clues and insights as to the mechanism. So I think we're going to have to piece together various types of study to try to answer the questions because one type of study like these observational air pollution studies, will allow us to address one slice of the questions that we have and then we need to put together other studies so that we can address other aspects that we're interested in to put it together. Dr. Davide Soldato: Thank you very much both of you. That was very interesting. Coming back to the results of the manuscript, we really focused up until now on PM2.5. But it's true that inside of the study you evaluated different pollutants. So, I was wondering whether you saw a similar association for other pollutants that were included in the study or whether the association for higher risk was observed only for PM2.5. Dr. Anna Wu: The results for NO2, NOx, PM10, and carbon monoxide were actually very compatible with the risk estimates that other studies have published as well as from the meta-analysis. So, I would say that our results from the other pollutants are actually very consistent with other results. I think one difference is that our PM2.5 estimates were based on the satellite-based PM2.5 estimates, whereas all the other pollutants were based on monitoring station estimates from EPA sponsored air monitoring stations. So, they are not measured in the same way. And I think different studies over time have used either monitoring station type measures for other pollutants. And I think we were particularly interested in PM2.5 because the measurement of PM2.5 in the monitoring world didn't start until around 2000. So, studies up until that time were less able to actually provide the assessment of PM2.5 as good as we can for air pollution. There's always misclassification. So, I think it's a matter of how much misclassification in the assessment. But, again, we are really limited in really just having exposure over one part of adult life. Dr. Davide Soldato: Thank you very much. And one potentially related question. We are speaking in general about air pollution, but I think that since we are considering residential addresses, probably we are capturing more either traffic pollution or pollution that comes from probably industries or stuff like that, which is mostly related to residential areas or the place where people live. But I think that in the end we also think about air pollution as something that can come from different forms. And one very interesting point, Dr. White, that you made in your editorial is also that there is a global change also in the way we are faced with air pollution. For example, you made the example of wildfires in your editorial and how this might potentially change exposure to air pollution, maybe for limited times, but with concentrations that are fairly higher compared to what we generally observed. So, I was wondering if you could comment a little bit on that and also, if there is potentially a way to also consider this in future epidemiological studies. Dr. Alexandra White: Yeah, so when we talk about exposure to fine particulate matter, PM2.5, we're assessing exposure to particles that are based on the size of the particle, and we're really not evaluating the types of particles that people are experiencing exposure to. And we know that, in general, that PM2.5 composition really varies geographically due to differing sources of exposure. So, like you were saying, there might be a stronger contribution to industry or from agriculture or from traffic. And so that could really change the PM2.5 exposure profile that individuals experience. And so it could be that this is another really important area that this research needs to consider, which could really help us identify what sources of exposure are most relevant. Wildfires are a really important growing concern. We know that wildfires are increasing in both intensity and duration and frequency, and we really don't understand the long-term health impacts of wildfires. But we know that wildfire associated PM2.5 might be one of the most dominant contributors to PM2.5 moving forward. And although we've seen historic declines in PM2.5 in the US after the Clean Air Act, those declines have really stalled. PM2.5 itself is projected to increase over the next few decades, so understanding different PM2.5 composition profiles and the sources that drive them can really help us identify the most important targets for any potential interventions. And wildfire PM2.5 in particular may be of concern because it's a combustion byproduct, and so it's thought to have more of the components that might, we hypothesize, are most relevant for breast cancer, such as PAHs or polycyclic aromatic hydrocarbons or metals. And so, these components are thought to act as endocrine disruptors, which may be particularly relevant for breast cancer. So, I think understanding this changing landscape of PM2.5 moving forward is going to be really important in understanding how PM2.5 contributes to cancers beyond just breast, but as well as other female hormone driven cancers and all of the cancers really. Dr. Davide Soldato: Thank you very much. So, one closing remark, because I think that in general, we have been really in a field of primary prevention for breast cancer where we were focusing on individual behaviors, for example, smoking cessation, reduction in alcohol intake, reduction of BMI, increase of physical activity. But I think that the evidence that is accumulating in the last three years or so is telling us more and more that we also need to shift the perspective on prevention going not only on individuals, but also as including environmental risk. So, I was wondering, how can we include this new evidence in the policies that we implement and how policymakers should act on the data that we have available right now? Dr. Anna Wu: I think it's really important that this new information is communicated to all the stakeholders, including our policymakers, so that they are, first of all, really aware that any changes and not actually adhering to current guidelines can have long lasting consequences, deleterious consequences. And I think it's important to also note that over 90% of the world actually live in areas where PM2.5 exceeds the limit. We have observed increases in breast cancer in many middle- and low-income countries, so I think it's particularly important to emphasize that this is really not just a western country issue, it is really a global issue. Dr. Alexandra White: I agree. And I would just add to that that air pollution is not something that an individual can really change on their own. There are things you can do, you can monitor air quality, you can try to live in a home that's far away from traffic. But really these are large scale problems that really require large scale solutions. And we know that policy changes can be effective here and that this is something that, in my opinion, is not something that we leave to the individual to change. This is something that we as a society should encourage change for the health of everyone. Dr. Davide Soldato: So, thank you very much again, Dr. Wu, Dr. White, for joining us today on the podcast.

Episode 2620: Dr. Neal addresses concerns about air fryers potentially producing harmful compounds like acrylamide and polycyclic aromatic hydrocarbons (PAHs). While air frying may still create acrylamide, it significantly reduces PAH production compared to traditional frying methods, making it a safer alternative. Quotes to ponder: "Air fryers use this same concept but instead of surrounding a food in hot oil, it circulates hot air around the food." "When researchers compared air frying to deep frying, they found that fewer PAHs were produced by air frying." "Adding spices, like turmeric and ginger, to the marinade has also been found to reduce the production of PAHs."

A team of astronomers has used NASA's James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star formation activity. For comparison, M82 is sprouting new stars 10 times faster than the Milky Way galaxy.Led by Alberto Bolatto at the University of Maryland, College Park, the team directed Webb's NIRCam (Near-Infrared Camera) instrument toward the starburst galaxy's center, attaining a closer look at the physical conditions that foster the formation of new stars.“M82 has garnered a variety of observations over the years because it can be considered as the prototypical starburst galaxy,” said Bolatto, lead author of the study. “Both NASA's Spitzer and Hubble space telescopes have observed this target. With Webb's size and resolution, we can look at this star-forming galaxy and see all of this beautiful, new detail.”Star formation continues to maintain a sense of mystery because it is shrouded by curtains of dust and gas, creating an obstacle in observing this process. Fortunately, Webb's ability to peer in the infrared is an asset in navigating these murky conditions. Additionally, these NIRCam images of the very center of the starburst were obtained using an instrument mode that prevented the very bright source from overwhelming the detector.While dark brown tendrils of heavy dust are threaded throughout M82's glowing white core even in this infrared view, Webb's NIRCam has revealed a level of detail that has historically been obscured. Looking closer toward the center, small specks depicted in green denote concentrated areas of iron, most of which are supernova remnants. Small patches that appear red signify regions where molecular hydrogen is being lit up by a nearby young star's radiation.“This image shows the power of Webb,” said Rebecca Levy, second author of the study at the University of Arizona, Tucson. “Every single white dot in this image is either a star or a star cluster. We can start to distinguish all of these tiny point sources, which enables us to acquire an accurate count of all the star clusters in this galaxy.”Looking at M82 in slightly longer infrared wavelengths, clumpy tendrils represented in red can be seen extending above and below the galaxy's plane. These gaseous streamers are a galactic wind rushing out from the core of the starburst.One area of focus for this research team was understanding how this galactic wind, which is caused by the rapid rate of star formation and subsequent supernovae, is being launched and influencing its surrounding environment. By resolving a central section of M82, scientists could examine where the wind originates, and gain insight on how hot and cold components interact within the wind.Webb's NIRCam instrument was well-suited to trace the structure of the galactic wind via emission from sooty chemical molecules known as polycyclic aromatic hydrocarbons (PAHs). PAHs can be considered as very small dust grains that survive in cooler temperatures but are destroyed in hot conditions.Much to the team's surprise, Webb's view of the PAH emission highlights the galactic wind's fine structure – an aspect previously unknown. Depicted as red filaments, the emission extends away from the central region where the heart of star formation is located. Another unanticipated find was the similar structure between the PAH emission and that of hot, ionized gas.“It was unexpected to see the PAH emission resemble ionized gas,” said Bolatto. “PAHs are not supposed to live very long when exposed to such a strong radiation field, so perhaps they are being replenished all the time. It challenges our theories and shows us that further investigation is required.”Webb's observations of M82 in near-infrared light spur further questions about star formation, some of which the team hopes to answer with additional data gathered with Webb, including that of another starburst galaxy. Two other papers from this team characterizing the stellar clusters and correlations among wind components of M82 are almost finalized.In the near future, the team will have spectroscopic observations of M82 from Webb ready for their analysis, as well as complementary large-scale images of the galaxy and wind. Spectral data will help astronomers determine accurate ages for the star clusters and provide a sense of timing for how long each phase of star formation lasts in a starburst galaxy environment. On a broader scale, inspecting the activity in galaxies like M82 can deepen astronomers' understanding of the early universe.“Webb's observation of M82, a target closer to us, is a reminder that the telescope excels at studying galaxies at all distances,” said Bolatto. “In addition to looking at young, high-redshift galaxies, we can look at targets closer to home to gather insight into the processes that are happening here – events that also occurred in the early universe.”
Developer plans townhouses, apartments along creek in Beacon A cleanup 17 years in the making is finally scheduled to begin by next month at the Beacon Terminal, as the site's new owner plans to convert the long-derelict buildings along Fishkill Creek into housing. The work is expected to begin sometime between Nov. 28 and Dec. 5 and last approximately three months at the 11-acre property, which is located at 555 South Ave., next to the parking lot for Madam Brett Park, and has been vacant since 1995. The cleanup, which involves the removal of 3,740 cubic yards of contaminated soil, is being done as part of the state Department of Environmental Conservation's (DEC) Brownfield program, in which developers receive tax breaks for cleaning up contaminated parcels, usually former factories. The site's current owner, Rodney Weber, is also the developer of Edgewater, a 246-unit, seven-building apartment complex near Tompkins Avenue that broke ground last year. The DEC said that Beacon Terminal will be "redeveloped by constructing new buildings and renovating some existing buildings to construct townhouses, duplex and triplex units." Weber declined to specify when the project might be coming before the Beacon Planning Board for review, but new construction is prohibited until the DEC determines that the cleanup is successful. Both Weber and the DEC said that remediation is not expected to impede access to Madam Brett Park. Originally built in 1879, Beacon Terminal served as the site of the Tioronda Hat Works Factory as well as the New York Rubber Co. and a factory for Tuck Tape. In 1974, volunteers working with Clearwater identified at least 27 illegal discharges from the Tuck Tape factory into Fishkill Creek. The company's vice president at the time asserted that despite the color and odor of the discharges, the factory was actually making the water cleaner. Previous testing of soil at the site revealed elevated concentrations of toluene, polychlorinated biphenyls (PCBs) and polyaromatic hydrocarbons (PAHs). Recent groundwater testing did not turn up any significant contamination. Although the DEC says the site does not currently pose threats to human health or the environment, that would change if the site were to become residential. The excavated soil will be disposed of "at an appropriately permitted facility equipped to receive the material," according to the DEC. They declined to provide further specifics as to where that facility might be. "Therefore, the contamination present at the site will be cleaned up by the applicant with DEC oversight to ensure it meets the protective standards in place for the proposed residential redevelopment of this former industrial property," said an agency representative. The DEC first moved to develop a cleanup plan in 2006 with the site's previous owner, Beacon Terminal Associates. After years of testing and development, the plan was completed in 2014. The site's owner, however, submitted a work plan to perform additional fieldwork before eventually choosing to implement the original cleanup plan. Beacon Terminal Associates then sold the site to Weber in 2016. A fire in early 2017 damaged the site even further; the cause of the blaze has never been determined.
We are living in a toxic soup filled with chemicals. When we're TTC, switching to non-toxic products is essential. We don't recommend throwing everything out because that can cause more stress. As each product expires, you can replace it with a non-toxic option. Except for your feminine hygiene and fragrances - swap those out immediately - hint: those pumpkin spice candles release harmful PAHs (polycyclic aromatic hydrocarbons) associated with reproductive issues. Studies have linked PAH exposure to reduced sperm count, lower concentration, abnormal shape, and decreased mobility. Additionally, various chemicals such as phthalates, SVOCs, BHT, and parabens have the potential to disrupt hormones, which is particularly concerning for individuals trying to conceive or those who are pregnant. So, where do we start? We're excited to share a beginner's guide to going toxin-free as you prepare for pregnancy success. I'm excited to welcome Anna Rapp to the podcast. Anna is the chief blogger at the popular fertility site To Make A Mommy.

Our scientific committees have had their last meetings of the year and in this episode we cover the outcomes of the Risk Assessment and Socio-Economic Analysis committees.Tim, the Chair of the Risk Assessment Committee and Maria who chairs the Socio-Economic Analysis Committee join us.We talk about the restriction of lead ammunition for hunting and outdoor sports shooting and lead used in fishing tackle. Here, the Socio-Economic Analysis Committee adopted its opinion on the costs and benefits and the Risk Assessment Committee carried out a further analysis of data from the European Food Safety Authority (EFSA) on the risks from ingesting lead through game meat.Also on the agenda were the restriction of Polycyclic aromatic hydrocarbons (PAHs) in clay targets for shooting and an opinion on occupational exposure limits for cobalt and inorganic cobalt compounds.Tim also talks us through setting a derived no-effect level for DOTE to protect workers, a chemical which is on the REACH Authorisation List of substances of very high concern.What the committees doThe two committees prepare scientific opinions that are used by the European Commission and EU member states when deciding how chemical risks need to be controlled. They are made up of scientists from EU Member States and have observers from EU organisations that represent different sectors and interests.Related episodes:Risk Assessment and Socio-Economic Analysis Committees: Cancer-causing PAHs in clay targets need an EU-wide banGive us feedbackMoreECHA's scientific committees support limiting lead use for outdoor shooting and fishing - ECHA news, 30 November 2022Highlights from December RAC and SEAC meetings - ECHA update, 8 December 2022Risk Assessment CommitteeSocio-Economic Analysis Committee**************Subscribe to our YouTube channelSubscribe to our Safer Chemicals PodcastSubscribe to our newsFollow us on:TwitterFacebookLinkedInVisit our websiteDisclaimer: Views expressed by interviewees do not necessarily represent the official position of the European Chemicals Agency.

Study of vibrational spectra of polycyclic aromatic hydrocarbons with phenyl side group by Anju Maurya et al. on Monday 28 November Computational study of polycyclic aromatic hydrocarbons (PAHs) with phenyl side group substituted at different positions is reported. The infrared spectral variations due to the position of phenyl substitution, ionization state and the size of the molecules are discussed and possible contribution of phenyl-PAHs to the mid-infrared emission features from astrophysical objects is analyzed. Structurally phenyl group substitution at 2nd position gives more stable species compared to substitution at other positions. Phenyl-PAHs exhibit new aromatic bands near 695 and 741 cm$^{-1}$ (14.4 and 13.5 $mu$m), due to contribution from quintet C-H wag, that compare well with minor features at 14.2 and 13.5 $mu$m observed in several astrophysical objects. Just as in plain PAHs, the C-C stretch vibrational modes ($sim$1600 cm$^{-1}$) have negligible intensity in neutrals, but the cations of all phenyl-PAHs exhibit significantly strong phenyl group C-C stretch peak close to class B type 6.2 $mu$m astrophysical band. In 2-phenylpyrene, it is the neutral molecule that exhibits this strong feature in the 6.2 $mu$m range along with other features that match with sub-features at 6.66 and 6.9 $mu$m, observed in astronomical spectra of some late type objects. The substitution of phenyl side group at solo position shifts the C-C stretch mode of parent PAH close to the region of 6.2 $mu$m astrophysical band. The results indicate possibility of phenyl-PAHs in space and the bottom-up formation of medium sized compact PAHs with phenyl side group in carbon rich cool circumstellar shells. Phenyl-PAHs need to be considered in modelling mid-infrared emission spectra of various astrophysical objects. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.13684v1

The NIEHS Superfund Research Program (SRP) is hosting a Risk e-Learning webinar series focused on scientific research and tools that can be used to promote health and resilience to climate change. The series will feature SRP-funded researchers, collaborators, and other subject-matter experts who aim to better understand and address how climate change affects human exposures to hazardous substances and the public health consequences of a changing climate and identify ways to build health resilience. The third and final session will highlight how climate-related disasters, and exposure to harmful chemicals redistributed during these events, affect people's health and well-being. Presenters will describe how certain populations are disproportionately exposed to harmful contaminants. Speakers will also share innovative tools to track environmental exposures and improve public health. Hurricanes are most devastating natural disasters, which dramatically change the physical landscape and take a heavy toll on human life, demolish infrastructure and property, and exacerbate environmental stressors that persists for months after their landfall. Naresh Kumar, Ph.D., of the University of Miami, will examine the distribution of polychlorinated biphenyls (PBCs) and heavy metals in the aftermath of hurricane Maria, which struck Puerto Rico in 2017, and their associated health risks to communities in Guánica Municipality. His team has been monitoring PCBs in Guánica Bay since 2013. Their data suggest that PCB concentration in Bay increased four time after hurricane Maria, and communities PCB exposure through inhalation and ingestion could have likely increased after the hurricane through ingestion and inhalation, because some of the community members rely on the Bay for seafood and fish. Deborah Watkins, Ph.D., of the University of Michigan School of Public Health and the Northeastern University SRP Center, will discuss the effect of Hurricane Maria on the PROTECT birth cohort in Puerto Rico. She will characterize changes in exposure to environmental contaminants among pregnant participants, comparing biomarker concentrations in samples collected before Hurricane Maria to levels in the weeks and months following the storm. Potential sources of hurricane-related exposures, such as drinking water and exhaust from gas-powered generators, as well as methods for linking exposures to adverse birth outcomes, will be discussed. Kim Anderson, Ph.D., of the Oregon State University SRP Center will talk about three different studies related to Arctic, wildfire, and hurricane cases. The first one is a collaboration with the Yupik community, this study utilized passive sampling devices deployed at eight locations in Troutman Lake, Alaska. Air, water and sediment pore-water deployed samplers were analyzed for 63 alkyl and unsubstituted polycyclic aromatic hydrocarbons (PAHs), 43 brominated and organophosphate flame retardants and 52 polychlorinated biphenyls (PCBs). For the second study, they investigated vapor-phase polycyclic aromatic hydrocarbons (PAHs) in indoor and outdoor air before, during and after wildfires using a community-engaged research approach. Paired passive air samplers were deployed at fifteen locations across four states. Twelve unique PAHs were detected only in outdoor air during wildfires. Indoor PAH concentrations were higher in 77% of samples across all sampling events. Even during wildfires, 58% of sampled locations still had higher indoor PAH air concentrations. Cancer and non-cancer inhalation risk estimates from vapor-phase PAHs were higher indoor than outdoor, regardless of wildfire impact. Consideration of indoor air quality and vapor-phase PAHs could inform public health recommendations regarding wildfires. The third study is related to Hurricane Harvey, which was associated with flood-related damage to chemical plants, oil refineries, and flooding of hazardous waste sites, including 13 Superfund sites. As clean-up efforts began, concerns were raised regarding the human health impact of possible increased chemical exposure resulting from the hurricane and subsequent flooding. Personal sampling devices in the form of silicone wristbands were deployed to a longitudinal panel of individuals within 45 days of the hurricane and again one year later in the Houston metropolitan area. Personal chemical exposures were generally higher post-hurricane Harvey. These three artic, wildfire, and hurricane studies found that chemicals are moving in different ways and chemical exposures change with the disasters.

Formation of c-C6H5CN ice using the SPACE TIGER experimental setup by Palo Maksyutenko et al. on Monday 10 October Benzonitrile (c-C6H5CN) has been recently detected in cold and dense regions of the interstellar medium (ISM), where it has been used as a signpost of a rich aromatic organic chemistry that might lead to the production of polycyclic aromatic hydrocarbons (PAHs). One possible origin of this benzonitrile is interstellar ice chemistry involving benzene (c-C6H6) and nitrile molecules (organic molecules containing the -CN group). We have addressed the plausibility of this c-C6H5CN formation pathway through laboratory experiments using our new setup SPACE TIGER. The SPACE TIGER experimental setup is designed to explore the physics and chemistry of interstellar ice mantles using laser-based ice processing and product detection methods. We have found that c-C6H5CN is formed upon irradiation of c-C6H6$:CH3CN binary ice mixtures with 2 keV electrons and Lyman-alpha photons at low temperatures (4-10 K). Formation of c-C6H5CN was also observed when c-C6H6 and CH3CN were embedded in a CO ice matrix, but it was efficiently quenched in a H2O ice matrix. The results presented in this work imply that interstellar ice chemistry involving benzene and nitrile molecules could contribute to the formation of the observed benzonitrile only if these species are present on top of the ice mantles or embedded in the CO-rich ice layer, instead of being mixed into the H2O-rich ice layer. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.03827v1
The Obscured Nucleus and Shocked Environment of VV 114E Revealed by JWST MIRI Spectroscopy by F. R. Donnan et al. on Monday 10 October We present a spectroscopic analysis of the heavily obscured nucleus and the surrounding environment of the eastern region of the nearby ($z = 0.02007$) interacting galaxy VV 114 with the James Webb Space Telescope (JWST) Mid-InfraRed Instrument (MIRI). We model the spectrum from 4.9 - 28 $mu$m to extract Polycyclic Aromatic Hydrocarbon (PAH) emission and the underlying obscured continuum. We find that the NE nucleus (A) is highly obscured where the low PAH equivalent width (EW) ratio, EW(12.7)/EW(11.3), reveals a dust enshrouded continuum source. This is confirmed by decomposing the continuum into nuclear and star-forming where the nuclear component is found to be typical of Compact Obscured Nuclei (CONs). The 11.3/6.2 PAH flux ratio is consistent with originating in star-forming regions rather than typical AGN. The second nucleus (B) is much less obscured, with PAH flux ratios also typical of star-forming regions. We do not detect any high ionisation lines such as [Ne V] or [Ne VI] which suggests that if an AGN is present it must be highly obscured. Additionally, we detect a shock front south of the secondary nucleus (B) in the [Fe II] (5.34 $mu$m) line and in warm molecular hydrogen. The 6.2 PAH emission does not spatially coincide with the low-J transitions of H$_2$ but rather appears strong at the shock front which may suggest destruction of the ionised PAHs in the post-shock gas behind the shock front. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.04647v1
Contribution of polycyclic aromatic hydrocarbon ionization to neutral gas heating in galaxies: model versus observations by O. Berné et al. on Tuesday 20 September [Abridged] The ionization of polycyclic aromatic hydrocarbons (PAHs), by ultraviolet (UV) photons from massive stars is expected to account for a large fraction of the heating of neutral gas in galaxies. Evaluation of this proposal, however, has been limited by our ability to directly compare observational diagnostics to the results of a molecular model describing PAH ionization. The objective of this article is to take advantage of the most recent values of molecular parameters derived from laboratory experiments and quantum chemical calculations on PAHs and provide a detailed comparison between modeled values and observational diagnostics for the PAH charge state and the heating efficiency for PAHs. Despite the use of a simple analytical model, we obtain a good agreement between model results and observational diagnostics over a wide range of radiation fields and physical conditions, in environments such as star-forming regions, galaxies, and protoplanetary disks. In addition, we found that the modeled photoelectric heating rates by PAHs are close to the observed cooling rates given by the gas emission. These results show that PAH ionization is the main source of neutral gas heating in these environments. The results of our photoelectric heating model by PAHs can thus be used to assess the contribution of UV radiative heating in galaxies (vs shocks, for instance). We provide the empirical formulas fitted to the model results, and the full python code itself, to calculate the heating rates and heating efficiencies for PAHs. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2208.08762v2
Tim Bowmer and Maria Ottati, Chairs of our committees for risk assessment and socio-economic analysis join us to share the highlights from their September meetings.On the agenda:Restricting polycyclic aromatic hydrocarbons (PAHs) in clay targets for shooting The restriction prevents further environmental emissions of these toxic and very persistent substances that build up in people and animals. Many PAHs are also known to cause cancer.Restriction of 2,4-dinitrotoluene (2,4-DNT) The Socio-Economic Analysis Committee concluded that the restriction is an appropriate EU-wide measure to address the identified risks while taking into account the benefits and costs to society. The proposal limits the placing on the market and use of 2,4-DNT in consumer and professional products. 2,4-DNT may cause cancer.Listen to our previous episode that covers 2,4-DNT.Nine opinions of the Risk Assessment Committee on the harmonised classification and labelling for several borate saltsUpdate on the proposed restriction of lead in outdoor shooting and fishing - consultation comments received and next stepsListen to our previous episode on lead in outdoor shooting and fishing.Tim and Maria walk us through the committees' opinions and how they reached their conclusions.What the committees doThe two committees prepare scientific opinions that are used by the European Commission and EU member states when deciding how chemical risks need to be controlled.

Resilience of small PAHs in interstellar clouds: Efficient stabilization of cyanonaphthalene by fast radiative cooling by Mark H. Stockett et al. on Monday 12 September After decades of speculation and searching, astronomers have recently identified specific Polycyclic Aromatic Hydrocarbons (PAHs) in space. Remarkably, the observed abundance of cyanonaphthalene (CNN, C10H7CN) in the Taurus Molecular Cloud (TMC-1) is six orders of magnitude higher than expected from astrophysical modeling. Here, we report absolute unimolecular dissociation and radiative cooling rate coefficients of the 1-CNN isomer in its cationic form. These results are based on measurements of the time-dependent neutral product emission rate and Kinetic Energy Release distributions produced from an ensemble of internally excited 1-CNN + studied in an environment similar to that in interstellar clouds. We find that Recurrent Fluorescence - radiative relaxation via thermally populated electronic excited states - efficiently stabilizes 1-CNN+ , owing to a large enhancement of the electronic transition probability by vibronic coupling. Our results help explain the anomalous abundance of CNN in TMC-1 and challenge the widely accepted picture of rapid destruction of small PAHs in space. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.05229v1
Contaminated Site Clean-Up Information (CLU-IN): Internet Seminar Audio Archives
"Risk-based cleanup goals are often calculated assuming that chemicals present in soil are absorbed by humans as efficiently as the chemicals dosed during the toxicity tests used to determine regulatory toxicity values (such as the Reference Dose or Cancer Slope Factor). This assumption can result in inaccurate exposure estimates and associated risks for some contaminated sites because the amount of a chemical absorbed (the chemical's bioavailability) from contaminated soil can be a fraction of the total amount present. Properly accounting for soil-chemical interactions on the bioavailability of chemicals from soil can lead to more accurate estimates of exposures to soil contaminants and improve risk assessments by decreasing uncertainty. The basis for this training course is the ITRC guidance: Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment (BCS-1). This guidance describes the general concepts of the bioavailability of contaminants in soil, reviews the state of the science, and discusses how to incorporate bioavailability into the human health risk assessment process. This guidance addresses lead, arsenic, and polycyclic aromatic hydrocarbons (PAHs) because evaluating bioavailability is better understood for these chemicals than for others, particularly for the incidental ingestion of soil. The target audience for this guidance and training course are: Project managers interested in decreasing uncertainty in the risk assessment which may lead to reduced remedial action costs. Risk assessors new to bioavailability or those who want additional confidence and training in the current methods and common practices for using bioavailability assessment to more accurately determine human health risk at a contaminated site. As a participant in this training you should learn to:Value the ITRC document as a ""go-to"" resource for soil bioavailability Apply the decision process to determine when a site-specific bioavailability assessment may be appropriate Use the ITRC Review Checklist to develop or review a risk assessment that includes soil bioavailability Consider factors that affect arsenic, lead and PAH bioavailability Select appropriate methods to evaluate soil bioavailability Use tools to develop site-specific soil bioavailability estimates and incorporate them into human health risk assessment Learners can envision themselves implementing the ITRC guidance through case study applications. Training participants are encouraged to view the associated ITRC guidance, Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment (BCS-1) prior to attending the class."

The following Climate Crisis news story is brought to you by the Corvallis Advocate. By John M. Burt Is the Air Worse Inside Or Out? It's easy to only pay attention to the quality of air outside, not inside, especially when the air quality index (AQI) suffers from high concentrations of noxious, cancer-causing polycyclic aromatic hydrocarbons (PAHs) from wildfires – which Oregonians have had their fair share of over the last few years. Under conditions like those, it's easy to forget that the quality of indoor air can actually be worse. Oregon State University's Kim Anderson, an environmental chemist, recently spoke with KLCC about the issue of indoor air, saying, “[E]ven when we see AQI numbers like 150 for example, the indoor air for these classic compounds called PAHs, are higher than outdoors. Specifically, AQIs oftentimes are really focused on particulate matter, but PAHs can exist both on the particulate, and they can be as a gas that we breathe.” Anderson conducted tests on air quality during the 2018 wildfire season. “People think air inside their house is perfectly clean, and that if we close all the windows when it is smoky outside there will be zero contaminants inside. That's just not true,” she said in a press release from OSU in 2020. What most people don't understand is that PAHs can be very small, and can seep into your house. Therefore, Anderson conducted an experiment where she placed air samplers inside and outside of buildings during fire season. The PAHs from inside were equal to or greater than from those outside. It was also found that PAHs can come from cooking, burning candles, and air fresheners. So don't be afraid to open your windows and let the not always completely clean air in. It's for your own health. By John M. Burt For more information about Corvallis air and other local news, go to TheCorvallisAdvocate.com

Our club decided that since we had leftover funds from the previous year, we didn't need to do a fundraiser for ourselves. So, we decided to do one for charity. Two of our officers previously raised a lot of money through selling Krispy Kreme Donuts, so we decided to do that as our fundraiser. We believed we would make the most profit with this company. We sold them for two weeks during November. They were supposed to be delivered and distributed in December; however, sports and activities were shut down for two weeks, so our dates got postponed. We were finally able to distribute the donuts at the beginning of January. We ended up having extras so we donated those to essential workers. We raised over $1,000 for Make-A-Wish and donated the money shortly after the donuts were delivered.
It's that time of the year when the days get warmer and Wisconsinites start their spring cleaning. For some, that means re-sealing their driveways, but certain pavement sealants can be harmful to both the environment and public health due to having high levels of polycyclic aromatic hydrocarbons, or PAH. In this episode, we sit down with Clean Wisconsin's water resource specialist Ezra Meyer and staff scientist Paul Mathewson to explain what PAHs are and how certain pavement sealants are toxic to the landscape and the health of Wisconsinites. We also talk with the former mayor of Port Washington to discuss what the town did to help curb PAH exposure and what the state government can do, as well. Background Reading Clean Wisconsin is a leading voice to end the use of high-PAH pavement sealants around the state. Read more on how they impact residents and the environment here. Read more from Paul Mathewson how high-PAH pavement sealants affect public health. Tip when looking for alternatives to high-PAH pavement sealants: Tar can have a lot of different names, and some other byproducts can have very high levels of PAHs. To be safe, check the “Material Safety Data Sheet” of the product (try searching online) and avoid anything including CAS #’s 64742-90-1, 65996-92-1, 65996-93-2, 65996-89-6, 69013-21-4, or 8007-45-2.

Polycyclic aromatic hydrocarbons -- PAHs -- are compounds that can be both good and bad. On the good side, they form the “bark” on a slice of brisket, which adds flavor. On the bad side, they can cause cancer, so it’s best to avoid them.PAHs are also bad for young fiddler crabs. In combination with direct sunlight, in fact, they’re killers.PAHs are among the compounds found in crude oil. When oil spills into the ocean, some of it settles to the bottom. Many of the compounds in the oil can remain in the sediments for years. None of those compounds is good for marine life. And PAHs are especially bad.A recent study found that juvenile fiddler crabs are among the organisms at risk from them. Researchers placed adult crabs that were ready to reproduce in tanks. The sediments at the bottom of the tanks contained PAHs, at levels that might be seen a few years after an oil spill.Female crabs carry their eggs outside their bodies. So as the crabs burrow, their eggs are exposed to whatever chemicals are mixed with the sediments.When the eggs hatch, the juveniles spend most of their time near the surface, where they’re exposed to sunlight. And the ultraviolet rays in the sunlight can cause a toxic reaction.The study found that adult crabs didn’t seem to be harmed by the combination of PAHs and sunlight. And neither did juveniles that weren’t exposed to the light. But most of the juveniles that did see strong daylight died -- victims of a toxic combination.

The NIEHS Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from SRP Centers awarded grants in 2020. In this session, awardees from University of Kentucky, Oregon State University, and Baylor College of Medicine will describe their research projects, accomplishments, and next steps. The University of Kentucky SRP Center, "Nutrition and Superfund Chemical Toxicity," explores human health challenges arising from exposure to halogenated organic substances such as polychlorinated biphenyls (PCBs), trichloroethylene, tetrachloroethene, and per- and polyfluoralkyl substances (PFAS). They conduct research on lifestyle changes such as nutrition and exercise and the relationship with pollutant exposure and disease risk. Center scientists also study remediation systems and engineering solutions for toxicant removal. The goal is to develop prevention strategies for diseases associated with chlorinated organic contaminants through a combination of enhanced remediation and healthy lifestyle components. The Oregon State University SRP Center, "PAHs: New Technologies and Emerging Health Risks," investigates polycyclic aromatic hydrocarbon (PAHs) mixtures before and after remediation. Center scientists work to track PAH movement through the environment, measure PAH exposure in individuals located near contaminated sites, predict the products of PAH transformation during remediation, determine the toxicity of complex PAH mixtures, and link PAH exposure to health outcomes. The Baylor College of Medicine SRP Center, "PAHs: Ultrasensitive Detection, Early-Life Exposures - Clinical Outcomes (Preterm Births, Chronic Lung Disease, and Neurocognitive Deficits), Prevention and Remediation," works in Harris County, Texas to explore maternal exposure to PAHs and the increased risk of preterm birth. They are investigating the molecular mechanisms behind the increased preterm birth risk after maternal exposure to PAH mixtures. Center scientists are also working to develop methods for detecting PAH-based compounds in air, water, and soil, remediation technologies to treat contaminated sediment, and strategies to prevent and reduce the health burden associated with PAH exposure.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.09.09.288852v1?rss=1 Authors: Sorhus, E., Donald, C. E., Dasilva, D., Thorsen, A., Karlsen, O., Meier, S. Abstract: Early life stages of fish are highly sensitive to crude oil exposure and thus, short term exposures during critical developmental periods could have detrimental consequences for juvenile survival. To obtain a broader understanding of the mechanisms behind crude oil toxicity, we administered crude oil to Atlantic haddock (Melanogrammus aeglefinus) in short term (3-day) exposures at two developmental time-points, before and after onset of heartbeat. A frequent sampling regime enabled us to determine and link immediate PAH uptake, metabolite formation and gene expression changes (cyp1a,b,c,d, bmp10, abcb1 and rhag). In general, the embryotoxic consequences were more severe in the earliest exposure, and oil droplet fouling enhanced the toxicity. This study detected circulation-independent, oil-induced gene expression changes and separated phenotypes linked to proliferation, growth and disruption of formation events at early and late developmental stages. A greater understanding of crude oil toxicity is essential for predicting the consequences of oil spills. Copy rights belong to original authors. Visit the link for more info
Jodi Flaws is a Professor of Comparative Biosciences and the Principal Investigator at the Reproductive Toxicology Laboratory in the College of Veterinary Medicine at the University of Illinois. Her lab studies the effects of environmental pollutants on the development and function of the human body, specifically relating to endocrine and reproductive health. Joining her is Karen Chiu, a PhD student whose work focuses on the impact and mechanism of various chemicals on the gut microbiome. On the podcast today Dr. Flaws and Karen Chiu discuss some of the health-damaging chemicals that have become ubiquitous in our food supply, personal care items, and even our carpeting and mattresses. They describe some of the physiological effects of these pollutants, including potentially deleterious changes to the gut microbiota and early reproductive aging. They also share tips for reducing and mitigating exposure to these compounds. After recording this podcast Karen talked with me a bit about organic foods - are they worth the additional cost to avoid some of these toxic chemicals? It turns out that while they are exposed to fewer pesticides, hormones, and antibiotics than conventional foods, it’s not true that organic foods are totally free of these contaminants. If you see the "USDA Organic" label, you can assume the food is at least 95% organic, while a product that claims to be “made with” organic ingredients is at least 70% organic. In her opinion, organic foods and products are the way to go when possible, given their lighter chemical load. It’s always a good idea to wash your produce to get as much of the pesticide residues off whether it be organic or conventional.

Risk-based cleanup goals are often calculated assuming that chemicals present in soil are absorbed by humans as efficiently as the chemicals dosed during the toxicity tests used to determine regulatory toxicity values (such as the Reference Dose or Cancer Slope Factor). This assumption can result in inaccurate exposure estimates and associated risks for some contaminated sites because the amount of a chemical absorbed (the chemical's bioavailability) from contaminated soil can be a fraction of the total amount present. Properly accounting for soil-chemical interactions on the bioavailability of chemicals from soil can lead to more accurate estimates of exposures to soil contaminants and improve risk assessments by decreasing uncertainty. The basis for this training course is the ITRC guidance: Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment (BCS-1). This guidance describes the general concepts of the bioavailability of contaminants in soil, reviews the state of the science, and discusses how to incorporate bioavailability into the human health risk assessment process. This guidance addresses lead, arsenic, and polycyclic aromatic hydrocarbons (PAHs) because evaluating bioavailability is better understood for these chemicals than for others, particularly for the incidental ingestion of soil. The target audience for this guidance and training course are: Project managers interested in decreasing uncertainty in the risk assessment which may lead to reduced remedial action costs. Risk assessors new to bioavailability or those who want additional confidence and training in the current methods and common practices for using bioavailability assessment to more accurately determine human health risk at a contaminated site.As a participant in this training you should learn to:Value the ITRC document as a "go-to" resource for soil bioavailability Apply the decision process to determine when a site-specific bioavailability assessment may be appropriate Use the ITRC Review Checklist to develop or review a risk assessment that includes soil bioavailability Consider factors that affect arsenic, lead and PAH bioavailability Select appropriate methods to evaluate soil bioavailability Use tools to develop site-specific soil bioavailability estimates and incorporate them into human health risk assessmentLearners can envision themselves implementing the ITRC guidance through case study applications. Training participants are encouraged to view the associated ITRC guidance, Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment (BCS-1) prior to attending the class.

The beauty industry isn’t so beautiful. Last week we covered the first 6 toxic ingredients to avoid in your skincare products. This week we tackle the remaining 6. How many products in your cabinets contain these ingredients? Please listen in - educate yourself for your health and peace of mind. Featured Product Clean Sourced Collagens Features five collagen types from four different sources! Contains eight grams of protein per serving Help reduce the appearance of fine lines and wrinkles Helps ease joint stiffness and discomfort Formulated with vitamin C, horsetail extract, and zinc for maximum absorption Odorless, flavorless formula easily mixes into water, juice, or smoothies * * * Why Skincare Impacts Your Health Skin is the biggest organ on your body. Skin absorbs everything that we put on it. Skincare is one of the most lucrative industries in the world. “Fake Skincare” In March of 2019, the Environmental Working Group, the EWG, reported that US regulation of chemicals and contaminants in cosmetics is falling behind the rest of the world. More than 40 nations, ranging from major industrialized economies like the United Kingdom and Germany, to developing states like Cambodia and Vietnam, have enacted regulations specifically targeting the safety and ingredients of cosmetics and personal care products. Some of these nations have restricted or completely banned more than 1,400 chemicals from cosmetic products. By contrast, the US Food and Drug Administration has banned or restricted only 9 chemicals for safety reasons. This is one of the most under-regulated industries but one of the most lucrative industries in the United States. Why Do Regulations Matter? The Environmental Working Group (EWG) They curate the Skin Deep database of ingredients used in personal care products and their safety concerns on human health. Biggest advocates for clean ingredients in your products. If your skincare product is backed by the EWG, it means they’ve done their homework, they’ve taken the time to look at clean ingredients. The EWG has a scale that rates products from 1 to 5 as far as cleanliness and safety. Top 12 Ingredients to Avoid & Why Ingredient: DEA COMPOUNDS (DIETHANOLAMINE) Typically Found In: DEA and DEA compounds are used to make cosmetics creamy or sudsy. Why You Should Avoid: These cause mild skin and eye irritation. Exposure to high doses of these chemicals has caused liver cancers and pre-cancerous changes in skin and thyroid. DEA is also possible hormone disruptor, has shown limited evidence of carcinogenicity and depletes the body of choline needed for fetal brain development. Ingredient: FRAGRANCE/PARFUM Typically Found In: Apart from being used in perfumes and deodorants, they are used in nearly every type of personal-care product. Of the thousands of chemicals used in fragrances, most have not been tested for toxicity, alone or in combination. Over 3000 chemicals are used to manufacture synthetic fragrances. Why You Should Avoid: These are often unlisted ingredients that are irritants and can trigger allergies, migraines, and asthma symptoms. The catchall term “fragrance” may mask phthalates, which act as endocrine disruptors and may cause obesity and reproductive and developmental harm. In laboratory experiments, individual fragrance ingredients have been associated with cancer and neurotoxicity. Federal law doesn’t require companies to list on product labels any of the chemicals in their fragrance mixture. Recent research from Environmental Working Group and the Campaign for Safe Cosmetics found an average of 14 chemicals in 17 name-brand fragrance products, none of them listed on the label. Ingredient: PEG COMPOUNDS (POLYETHYLENE GLYCOLS) Typically Found In: Scrubs, body wash, makeup, toothpaste PEGs are widely used in cosmetics as thickeners, solvents, softeners, and moisture-carriers and hence used for products requiring a cream base and also in laxatives. Why You Should Avoid: Those tiny plastic beads in face or lip scrubs and exfoliating washes are made from polyethylene (used because they’re gentler on the skin than natural exfoliators like walnut shells). These synthetic chemicals are frequently contaminated with 1,4-dioxane, which the U.S. government considers a probable human carcinogen and which readily penetrates the skin. Polyethylene has been noted as a skin irritant and should never be used on broken skin. Polyethylene beads in scrubs and body washes also are not filtered by our sewage systems, meaning they can collect pollutants and travel into waterways, where they’re consumed by fish and marine animals. Ingredient: PETROLATUM Typically Found In: Petrolatum, also known as petroleum jelly, is used in industry to lubricate machinery – so what is it doing to our bodies? Petrolatum has been used for years to lock in moisture, heal chapped lips, soothe noses raw from sniffles, and protect against diaper rash, as well as to treat cuts and burns. It is an ingredient in one out of every 14 cosmetic products on any given shelf, which includes 15 percent of lipsticks and 40 percent of baby products. So what’s the big deal? Why You Should Avoid: Scarily enough, petroleum byproduct has been found in breast tumors, strongly suggesting it is a breast-cancer-promoting substance. It also suffocates the skin, blocking oxygen absorption and aggravating acne. Petrolatum locks in moisture, yes – but does not allow moisture to be absorbed from the atmosphere. In short, our body gets accustomed to petrolatum’s barrier and slowly become less and less efficient at its own detoxifying and moisturizing processes. Ingredient: TRICLOSAN Typically Found In: Triclosan is used mainly in antiperspirants/deodorants, cleansers, and hand sanitizers as a preservative and an anti-bacterial agent. Also used in laundry detergent, facial tissues, and antiseptics for wounds. Triclosan is classified as a pesticide. Why You Should Avoid: Triclosan was all the rage as antibacterial products became ubiquitous in the 1990s. But…it can pass through skin and can affect the body’s hormone systems—especially thyroid hormones, which regulate metabolism—and may disrupt normal breast development. Widespread use of triclosan may also contribute to bacterial resistance to antimicrobial agents. It acts like estrogen in the body and has high rates of skin allergy. (High toxicity concern.) The Canadian Medical Association has called for a ban on antibacterial consumer products, such as those containing triclosan. Even the FDA agrees that there is no health benefit to humans who use triclosan, and in 2013 ruled that manufacturers using it had to demonstrate that there were no long-term detrimental effects. We personally use naturally antibacterial and antiseptic agents like tea tree oil. Ingredient: SILOXANES Siloxanes are a group of chemicals that are, as the name suggests, derived from silicone. Typically Found In: Cyclomethicone and ingredients ending in “siloxane” make hair products dry quickly and deodorant creams slide on easily. They are also used extensively in moisturizers and facial treatments to soften and smoothen and in medical implants. Why You Should Avoid: The risks associated with siloxanes are far too many. Siloxanes are known endocrine disruptors that interfere with human hormone function, and could even possibly impair fertility. Research has shown that they not only cause uterine tumors, but can also skew the functioning of neurotransmitters in the nervous system. On top of that, siloxanes resist degradation and therefore pose harm to aquatic life and wildlife. Ingredient: PHTHALATES (DIBUTYL PHTHALATE) Typically Found In: nail polish and other nail products, perfume, makeup remover, hairspray, deodorant Why You Should Avoid: Phthalates are sneaky endocrine disruptors, which means they mimic the body’s hormones, therefore throwing the entire endocrine system off balance. They cause both hormonal and neurological damage, and in the case of pregnant women, may also cause major birth defects. The worst part? You will rarely find the word “phthalates” on a label. Some products do market themselves as phthalate-free, but what about the other slew of synthetics on our department store’s beauty shelf? You can identify phthalates by their abbreviated chemical components: DBP (di-n-butyl phthalate), DEP (diethyl phthalate), DMP (dimethyl phthalate), DEHP (di-2-ethylhexyl), and BzBP (benzylbutyl phthalate). Ingredient: SULPHATES (SODIUM LAURATE, LAURYL SULPHATE OR SLS) Typically Found In: Primarily used as a foaming agent or detergent to be found in shampoos, facial cleansers, mouthwash, toothpaste, bubble bath products, household and utensil cleaning detergents. Why You Should Avoid: Depending on the manufacturing process, Sodium laureth sulfate may be contaminated with ethylene oxide and 1,4-dioxane. Both contaminants may cause cancer. Also, ethylene oxide may harm the nervous system and interfere with human development, and 1,4-dioxane is persistent. In other words, it doesn’t easily degrade and can remain in the environment long after it is rinsed down the shower drain. SLS has been shown to cause or contribute to: skin irritation, canker sores, disruptions of skin’s natural oil balance and eye damage. It is also widely believed to be a major contributor to acne (especially cystic acne) around the mouth and chin. Ingredient: PARABENS (METHYL-, ETHYL-, PROPYL-, BUTYL-, ISOBUTYL-) Typically Found In: A common and very cheap cosmetic preservative, the second most common skincare ingredient. Found in: makeup, moisturizer, shaving gel, shampoo, personal lubricant and spray tan products Why You Should Avoid: Synthetic parabens are toxic in large or cumulative quantities, as the body stores parabens in many tissue types. They can cause allergic reactions, skin rashes and irritation. Parabens have been shown to mimic estrogen which disrupts normal hormone function. Exposure to external estrogen’s have been shown to increase the risk of breast cancer and increase cell abnormalities. There should be no excuse for your skincare products to still have Parabens. The FDA acknowledges several studies linking parabens, which mimic estrogen, to breast cancer, skin cancer and decreased sperm count, but has not ruled that it is harmful. According to the European Commission’s Scientific Committee on Consumer Products, longer chain parabens like propyl and butyl paraben and their branched counterparts, isopropyl and isobutylparabens, may disrupt the endocrine system and cause reproductive and developmental disorders. Look for ingredients with the suffix “-paraben” as well—paraben-free products will be labeled as such. Ingredient: FORMALDEHYDE Typically Found In: These are primarily preservatives commonly found in cosmetics. It is also found in baby bath soap, nail polish, eyelash adhesive and hair dyes. Look for: DMDM hydantoin, diazolidinyl urea, imidazolidinyl urea, methenamine, quaternium-15, and sodium hydroxymethylglycinate. These ingredients slowly and continuously release small amounts of formaldehyde. Why You Should Avoid: Short-term health impacts include irritation to the eyes, nose and throat, and many studies show it causes allergic skin reactions and skin rashes. In fact, it was awarded 2105 Contact Allergen of the Year by American Contact Dermatitis Society. Long term, Formaldehyde has a long list of adverse health effects, including immune-system toxicity, respiratory irritation and cancer in humans. Formaldehyde is a recognized human carcinogen. Ingredient: BHA AND BHT (BUTYLATED HYDROXYANISOLE AND BUTYLATED HYDROXYTOLUENE) Typically Found In: Butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) are closely related chemicals – preservatives commonly used in cosmetics, personal care products (mainly shampoos, perfumes, deodorants, body lotions), and even food and food packaging. Why You Should Avoid: The National Toxicology Program classifies butylated hydroxyanisole (BHA) as “reasonably anticipated to be a human carcinogen.” It can cause skin depigmentation. In animal studies, BHA produces liver damage and causes stomach cancers such as papillomas and carcinomas and interferes with normal reproductive system development and thyroid hormone levels. The European Union considers it unsafe in fragrance. Opt for a BHA and phthalate-free perfume. Ingredient: COAL-TAR DYES Polycyclic aromatic hydrocarbons (PAHs) are a group of chemicals that occur naturally in coal, crude oil and gasoline. Typically Found In: Found in: hair dyes, lipstick, cosmetic, shampoo Why You Should Avoid: Phenylenediamine, used in hair dyes, has been found to be carcinogenic in laboratory tests conducted by the U.S. National Cancer Institute and National Toxicology Program. Coal tar is recognized as a human carcinogen and the main concern are their potential as carcinogens. As well, colors may be contaminated with low levels of heavy metals and some contain aluminum (a neurotoxin). This is of particular concern when used in cosmetics that may be ingested, like lipstick. * * * Deeper Dive Resources The Environmental Working Group https://www.ewg.org/ EWG’s Skin Deep Cosmetics Database https://www.ewg.org/skindeep/ Global Regulatory Lists of Banned or Restricted Cosmetic Ingredients and Positive Lists https://www.chemsafetypro.com/Topics/Cosmetics/Regulatory_Lists_of_Cosmetic_Ingredients_Banned_Cosmetic_Ingredients,_Restricted_Cosmetic_Ingredients_and_Positive_Lists.html Prohibited & Restricted Ingredients in Cosmetics (FDA) https://www.fda.gov/cosmetics/cosmetics-laws-regulations/prohibited-restricted-ingredients-cosmetics DEA Compounds https://www.fda.gov/cosmetics/cosmetic-ingredients/diethanolamine Fragrances in Cosmetics https://www.fda.gov/cosmetics/cosmetic-ingredients/fragrances-cosmetics Phthalates https://www.cdc.gov/biomonitoring/Phthalates_FactSheet.html Campaign for Safe Cosmetics http://www.safecosmetics.org/ PEG Compounds https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4505343/ 1,4-Dioxane https://www.epa.gov/sites/production/files/2014-03/documents/ffrro_factsheet_contaminant_14-dioxane_january2014_final.pdf Petrolatum http://www.safecosmetics.org/get-the-facts/chemicals-of-concern/petrolatum/ Triclosan https://www.mayoclinic.org/healthy-lifestyle/adult-health/expert-answers/triclosan/faq-20057861 FDA Ruling on Triclosan https://www.fda.gov/news-events/press-announcements/fda-issues-final-rule-safety-and-effectiveness-antibacterial-soaps Siloxanes https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4884743/

This week we dive into the murky ingredients in your skincare products. Many of these are hormone disrupters and known carcinogens. Since our skin is our largest organ and we're all about limiting toxicity in our lives this episode was a MUST. Tune in this week to learn how to be a savvy skincare shopper!

Skin absorbs everything that we put on it. Skincare is one of the most lucrative industries in the world. “Fake Skincare” In March of 2019, the Environmental Working Group, the EWG, reported that US regulation of chemicals and contaminants in cosmetics is falling behind the rest of the world. More than 40 nations, ranging from major industrialized economies like the United Kingdom and Germany, to developing states like Cambodia and Vietnam, have enacted regulations specifically targeting the safety and ingredients of cosmetics and personal care products. Some of these nations have restricted or completely banned more than 1,400 chemicals from cosmetic products. By contrast, the US Food and Drug Administration has banned or restricted only 9 chemicals for safety reasons. This is one of the most under-regulated industries but one of the most lucrative industries in the United States. Why Do Regulations Matter? The Environmental Working Group (EWG) They curate the Skin Deep database of ingredients used in personal care products and their safety concerns on human health. Biggest advocates for clean ingredients in your products. If your skincare product is backed by the EWG, it means they’ve done their homework, they’ve taken the time to look at clean ingredients. The EWG has a scale that rates products from 1 to 5 as far as cleanliness and safety. Top 12 Ingredients to Avoid & Why – The First 6! Ingredient: PHTHALATES (DIBUTYL PHTHALATE) Typically Found In: nail polish and other nail products, perfume, makeup remover, hairspray, deodorant Why You Should Avoid: Phthalates are sneaky endocrine disruptors, which means they mimic the body’s hormones, therefore throwing the entire endocrine system off balance. They cause both hormonal and neurological damage, and in the case of pregnant women, may also cause major birth defects. The worst part? You will rarely find the word “phthalates” on a label. Some products do market themselves as phthalate-free, but what about the other slew of synthetics on our department store’s beauty shelf? You can identify phthalates by their abbreviated chemical components: DBP (di-n-butyl phthalate), DEP (diethyl phthalate), DMP (dimethyl phthalate), DEHP (di-2-ethylhexyl), and BzBP (benzylbutyl phthalate). Ingredient: SULPHATES (SODIUM LAURATE, LAURYL SULPHATE OR SLS) Typically Found In: Primarily used as a foaming agent or detergent to be found in shampoos, facial cleansers, mouthwash, toothpaste, bubble bath products, household and utensil cleaning detergents. Why You Should Avoid: Depending on the manufacturing process, Sodium laureth sulfate may be contaminated with ethylene oxide and 1,4-dioxane. Both contaminants may cause cancer. Also, ethylene oxide may harm the nervous system and interfere with human development, and 1,4-dioxane is persistent. In other words, it doesn’t easily degrade and can remain in the environment long after it is rinsed down the shower drain. SLS has been shown to cause or contribute to: skin irritation, canker sores, disruptions of skin’s natural oil balance and eye damage. It is also widely believed to be a major contributor to acne (especially cystic acne) around the mouth and chin. Ingredient: PARABENS (METHYL-, ETHYL-, PROPYL-, BUTYL-, ISOBUTYL-) Typically Found In: A common and very cheap cosmetic preservative, the second most common skincare ingredient. Found in: makeup, moisturizer, shaving gel, shampoo, personal lubricant and spray tan products Why You Should Avoid: Synthetic parabens are toxic in large or cumulative quantities, as the body stores parabens in many tissue types. They can cause allergic reactions, skin rashes and irritation. Parabens have been shown to mimic estrogen which disrupts normal hormone function. Exposure to external estrogen’s have been shown to increase the risk of breast cancer and increase cell abnormalities. There should be no excuse for your skincare products to still have Parabens. The FDA acknowledges several studies linking parabens, which mimic estrogen, to breast cancer, skin cancer and decreased sperm count, but has not ruled that it is harmful. According to the European Commission’s Scientific Committee on Consumer Products, longer chain parabens like propyl and butyl paraben and their branched counterparts, isopropyl and isobutylparabens, may disrupt the endocrine system and cause reproductive and developmental disorders. Look for ingredients with the suffix “-paraben” as well—paraben-free products will be labeled as such. Ingredient: FORMALDEHYDE Typically Found In: These are primarily preservatives commonly found in cosmetics. It is also found in baby bath soap, nail polish, eyelash adhesive and hair dyes. Look for: DMDM hydantoin, diazolidinyl urea, imidazolidinyl urea, methenamine, quaternium-15, and sodium hydroxymethylglycinate. These ingredients slowly and continuously release small amounts of formaldehyde. Why You Should Avoid: Short-term health impacts include irritation to the eyes, nose and throat, and many studies show it causes allergic skin reactions and skin rashes. In fact, it was awarded 2105 Contact Allergen of the Year by American Contact Dermatitis Society. Long term, Formaldehyde has a long list of adverse health effects, including immune-system toxicity, respiratory irritation and cancer in humans. Formaldehyde is a recognized human carcinogen. Ingredient: BHA AND BHT (BUTYLATED HYDROXYANISOLE AND BUTYLATED HYDROXYTOLUENE) Typically Found In: Butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) are closely related chemicals – preservatives commonly used in cosmetics, personal care products (mainly shampoos, perfumes, deodorants, body lotions), and even food and food packaging. Why You Should Avoid: The National Toxicology Program classifies butylated hydroxyanisole (BHA) as “reasonably anticipated to be a human carcinogen.” It can cause skin depigmentation. In animal studies, BHA produces liver damage and causes stomach cancers such as papillomas and carcinomas and interferes with normal reproductive system development and thyroid hormone levels. The European Union considers it unsafe in fragrance. Opt for a BHA and phthalate-free perfume. Ingredient: COAL-TAR DYES Polycyclic aromatic hydrocarbons (PAHs) are a group of chemicals that occur naturally in coal, crude oil and gasoline. Typically Found In: Found in: hair dyes, lipstick, cosmetic, shampoo Why You Should Avoid: Phenylenediamine, used in hair dyes, has been found to be carcinogenic in laboratory tests conducted by the U.S. National Cancer Institute and National Toxicology Program. Coal tar is recognized as a human carcinogen and the main concern are their potential as carcinogens. As well, colors may be contaminated with low levels of heavy metals and some contain aluminum (a neurotoxin).

I put out the message asking for more guests. John Powers was requested a lot, so we made it happen. That's just what we do here at the Coal Region Campfire. Make your requests into reality. I never had him as a teacher, and really didn't know him in high school, but it was an absolute pleasure speaking with him, and, once again, you can feel the passion he has for teaching, and the way former students talk about him it's very obvious he left a lasting impression. CACL and Darren March = Sponsors. You know this already.
Researchers are finding some of the chemicals used in pavement and driveway sealants are making their way into the environment. That could be putting the health of people and aquatic life at risk. These chemicals are called Polycyclic Aromatic Hydrocarbons, PAHs. They’re commonly found in low levels just about anywhere something is burned. But, the levels of PAHs are much, much higher in certain pavement sealing products, coal tar based sealants.
We’re back for another info-packed episode of Keto Talk! In this episode, Jimmy and Dr. Will Cole answer your questions about Edema After Starting Keto, Upper Respiratory Infection, Pituitary Microadenoma, Swollen Ankles On Keto, Increased Blood Pressure And Racing Heart Eating Very Low-Carb , and more! “Saturated fats can handle a higher temperature as a general rule, and the benefits far outweigh the concerns.” - Dr. Will Cole Will and Jimmy are featured speakers at the August 17, 2019 Toronto conference called Great Canadian Keto. HOT TOPICS: Is it possible to be making therapeutic blood ketone levels, but still experience higher blood sugar levels at the same time? Are you concerned about increased cancer risk because of heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) in meat? How should I handle eating keto when I work the night shift half the week and daytime the other half of the week? If heating fats make them more carcinogenic, then why would you ever consume cooked fats from even bone broth? How can someone without a gallbladder who has also had gastric bypass surgery do a ketogenic diet? Paid advertisement “Folks think that you can’t eat keto after having their gallbladder removed. Christine had hers removed in 2006 and she eats more fat than I do.” Jimmy Moore HEALTH HEADLINES: The Keto diet gets lots of attention for weight loss.

Missing pizza on the keto diet? This major chain now has a low-carb crust STUDY: Striking study reveals how dietary fats enter the brain and cause depression Paid advertisement Your Questions: – Why did I develop edema in my lower extremities after I started eating a low-carb, high-fat, ketogenic diet? Hey Jimmy and Will, I am a natural bodybuilder and have been for over 40 years now. For the past decade, I’ve consume a 100% grass-fed and non-GMO organic diet. In fact I was Paleo before I even knew what that was. In 2017 I started on keto and it was an easy move over from Paleo. I got into a state of nutritional ketosis very quickly with blood sugar in the 80’s and blood ketones between 1-2. My blood pressure improved to 110/75 and fasting insulin down to 3.8. I felt great and had no medical issues whatsoever. But then I noticed something pop up out of nowhere last year where I developed edema in my calves, ankles, and feet. I tried upping my magnesium, drinking more water, taking in substantially more sodium, moderating my protein, and doing an 18/6 intermittent fasting schedule. None of it has worked. I weigh 150 pounds have have 9% body fat. Do you have any further suggestions I can do to help with this? What is it about going keto that perhaps let to this condition? Warmest regards, Joe – Why have I developed several upper respiratory infections ever since I started keto when I’ve never been sick like this in my life? Hi Jimmy and Will. Thank you for what you guys do for everyone in the keto community. I only just found this podcast this year and have binged listened to almost all of them. I am a registered nurse and have taking care of the sickest of the sick in the city of Pittsburgh. I now work normal M-F hours with low stress. I’m on Synthroid for Hashimoto’s hypothyroidism, but my immune system has been so stellar I’ve hardly ever gotten sick. But ever since starting on keto, I’ve had three upper respiratory infections eating this way. While I’ve lost 20 pounds, have great brain health, increased my energy, and spontaneously intermittent fast for 16 hours at a time while stabilizing my blood sugar and increasing my blood ketone levels, these respiratory issues are discouraging and throwing me for a loop. I’m assuming it’s a gut health thing that needs to be healed from years of neglect before starting keto. How do I provide a boost to my immune health to prevent another infection from developing? Thanks for your help, Rosslyn – How do I manage my cravings to consume way too many calories on keto because of my pituitary microadenoma condition? Hi Jimmy and Dr. Cole, I’ve been on a weight loss journey for about a year, and went keto 6 months ago. Before keto, I lost over 15 pounds, then switched to keto to optimize my athletic performance and brain function while continuing to lose weight. I also wanted to try to heal my hormones with a low-carb, high-fat diet. I have a pituitary microadenoma which is essentially a small tumor on my pituitary gland that secretes high levels of prolactin. These high levels of prolactin suppress estrogen production. In short, it means I have high prolactin, low estrogen, and have not had a period in 2 years which ultimately is leading to infertility. I am wondering if this hormone imbalance could be suppressing my weight loss and/or increasing my hunger and questioning whether keto would be a useful tool to balance my hormones. I haven’t lost any weight since beginning on keto and I still struggle with food addiction/binge eating. Unlike what other people report eating a ketogenic diet, I don’t really get full or reach satiety until I’ve consumed way too many calories. I know calories aren’t what they’ve been made out to be, but they do have to count because they’ll get stored as body fat if consumed in excess, right? Got any tips for me? Thanks guys and keto on! Kayla from Canada – What can I do about the swelling in my ankles and lower legs that started happening after I went keto? Hi guys, I love your podcast! I’ve been keto for over a month and have been testing for blood ketones. I’m doing well but I have been retaining water in my ankles and lower legs. I get leg/shin cramps at night so I have been adding a magnesium/potassium supplement to help. They have eased up quite a bit but the swelling has increased. Ketones are still strong, but my weight loss stalled out after losing eight pounds. I had a total hysterectomy at 35 years old with no hormone replacement therapy and I’m 56 now. Any suggestions on what to try next? Thank you for your help, Dede Paid advertisement KETO TALK MAILBOX: – Why does my blood pressure and heart rate shoot way up when I am eating very low-carb keto and engaging in periods of fasting? Hey Jimmy and Dr. Cole, I’m listening to an older episode where a woman had asked about cortisol and low-carb. I haven’t taken a test for it yet, but when I fast, long-term or intermittent, and consume a very low-carb diet (under 20), my blood pressure shoots through the roof and I get major heart palpitations. When this happens, I purposely knock myself out of ketosis and my heart rate and blood pressure normalize again. I’ve been keto for four months and I’m not really losing any weight yet. I’ve felt pretty good eating this way, but I have noticed being a bit more tired than normal at times. I take all the recommended electrolyte supplements and plenty of water and salt. So what am I doing wrong? Thank you, Lisa

Grilling: the original human cooking method. Unfortunately we are finding out that grilling, especially grilling meats, can create harmful carcinogenic compounds in our food that we definitely want to avoid. Luckily, there is a solution that comes in the form of alcoholic marinades. A researcher from the University of Porto, Portugal has published studies showing that alcoholic marinades particularly those with dark beer and wine cut the formation of more than 70% of these carinogenic compounds in pan fried beef and in bar-b-q por.
