There has been a lot of coverage of PFAS in the news. That's shorthand for per- and polyfluorinated substances, and it’s a class of chemicals commonly found in stain proof, water-resistant, and nonstick products.
A lot of the news coverage mentions that the chemicals can be harmful to humans. But what exactly does that mean?
Courtney Carignan, an assistant professor in the Department of Food Science and Human Nutrition at Michigan State University, joined Stateside to help us answer that question.
Carignan discussed the chemicals' effect on the endocrine system and the different ways humans can get exposed to the chemical. She also discussed her own study that reported water supplies for millions of Americans exceeded the government’s lifetime health advisory for exposure to the chemical family.
