    Join host Ryan Feldman in an insightful episode of "The Poison Lab" as he sits down with Dr. John Downs, Director of the Virginia Poison Center, and one of the leading experts on per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals." Known for their persistence in the environment and human body, PFAS have raised significant public health concerns over the past few decades. Dr. Downs shares his journey through occupational medicine, toxicology, and public health, which uniquely positioned him to provide expertise on PFAS exposure, health risks, and ongoing regulatory efforts. Together, they delve into the origins, uses, and potential health effects of these ubiquitous compounds, while examining government policies, environmental impact, and strategies to reduce exposure. A must-listen for anyone interested in the intersection of environmental health and toxicology!

This has led to contamination of groundwater around military installations and airports.Fast food wrappers and other consumer products: PFAS are used to make products water and oil resistant, including fast food wrappers, clothing, upholstery, and popcorn bags.Biosolids: The nitrogenous waste produced after wastewater treatment, have been found to contain concentrated PFAS. These biosolids are sometimes sold to farms as fertilizer, potentially contaminating water and crops.Ski wax: Ski waxers have been found to have a high degree of PFAS...
