It's not just "association"; PTFE literally is a PFAS. My point is there's a major different between PFAS polymers and PFAS small molecules. From https://pubchem.ncbi.nlm.nih.gov/source/hsdb/833 https://pubchem.ncbi.nlm.nih.gov/source/hsdb/833 : "Perfluorooctanoic acid (PFOA), also known as C8, is another man-made chemical. It is used in the process of making Teflon and similar chemicals (known as fluorotelomers), although it is burned off during the process and is not present in significant amounts in the final products." [GenX is very similar.] And there's no technical reason why manufacturing PFAS polymers necessarily has to result in PFAS small molecule pollution. The waste could be captured and treated with processes such as supercritical water oxidation. This would of course cost more, but seeing as there's no good substitute for PFAS polymers, I'd happily pay more for them. Pollution, like all externalities, is a market failure, and it's the government's job to fix market failures with regulation.
