The list of issues that the wiki article claims are "high certainty" is also quite concerning to me: https://en.m.wikipedia.org/wiki/Per-_and_polyfluoroalkyl_sub...

At the very least, seems that the production is being ramped down - quick skim of the article yielded this quote: "Their [PFASs'] production has been regulated or phased out by manufacturers, such as 3M, DuPont, Daikin, and Miteni in the US, Japan, and Europe."

Basically, the US government allows companies to sell new chemicals they invent, completely unregulated. You could make a toxin today that kills everyone who touches it 10 years after they ingest it, and you would be free to market and sell this product. The chemical is presumed safe until evidence to the contrary comes to the knowledge of the govt.

That's how Dupont poisoned people all over the world. They sold unregulated chemicals they invented that nobody but them knew about.

One report by the Centers for Disease Control and Prevention’s National Health and Nutrition Examination Survey (NHANES) found PFAS in the blood of 97% of Americans... The number of new PFAS chemicals appear to be increasing, and exposure is difficult to assess. - https://www.niehs.nih.gov/health/topics/agents/pfc/index.cfm
