PFAS is a huge family of long lasting fluorinated chemicals. The ones that are bio-absorbed typically are liquid at normal temperatures. Gasoline and plastic are both hydrocarbons, but gasoline is toxic and long chain polyethylene is not. So we are sort of in this state where some Hacker News savior is shouting “hydrocarbons dangerous!!!”, when the story is more like liquid PFAS is a problem, but Teflon is safe like polyethylene is safe. Don’t drink hexane, but the 200-ane found in polyethylene won’t be absorbed even when you eat it.
Bottom line is that all the liquid PFAS has been pulled from the market. The last thing I have seen was some ski racing wax had these liquid PFAS compounds, and they got fined pretty heavily.
