Part 2/5:
PFAS, including chemicals like PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate), consist of thousands of substances historically used in cookware and various consumer products. Although PFOA has been banned in the United States, alternatives like Teflon and its PTFE (polytetrafluoroethylene) derivatives can emit fuming toxins when subjected to high temperatures, particularly beyond 400°F.
The dangers associated with these chemicals extend beyond simple cookware usage; they have raised serious environmental and health concerns, prompting a collective push towards greater consumer awareness and safety.
