A Chemical Conversation

Welcome to A Chemical Conversation – a podcast about pollution with author Callie Lyons. In the first five episodes we’ll be talking about C8 or PFOA or perfluorooctanoic acid, the manmade substance used by DuPont in the manufacture of Teflon and thousands of other consumer applications since the 1950s. It belongs to a larger family of chemicals called PFAS, which are under suspicion because of their toxicity, pervasiveness, and bio-persistence.
