"DuPont studies show that the Teflon offgases toxic particulates at
446°F. At 680°F Teflon pans release at least six toxic gases,
including two carcinogens, two global pollutants, and MFA, a chemical
lethal to humans at low doses. At temperatures that DuPont scientists
claim are reached on stovetop drip pans (1000°F), non-stick coatings
break down to a chemical warfare agent known as PFIB, and a chemical
analog of the WWII nerve gas phosgene."
