PFAS Explained

You may have seen or heard the acronym PFAS floating around, or perhaps heard of "forever chemicals." Or maybe you've heard that there are some potential concerns with using non-stick cookware, but weren't sure what it was all about. Around since the 1940s, PFAS are used in a variety of ways including in non-stick cookware, stain, grease, and water-resistant clothing, some firefighting foam, and some cosmetics. However, there are a number of concerns around these chemicals, some of which have already been phased out of discussion. Casey and Sara discuss the issues around and potential paths forward from PFAS.
