PFOA/PFOS propaganda is wild. They're very useful substances. Yes, acute exposures cause harm, but the same can be said of salt. Though with modern instrumentation we can measure presence in parts per trillion, I have seen no evidence at all that likely bioaccumulative pathways have resulted in harm to humans. Even the opening of this article levers "we found it" with "EPA regulates it in drinking water" as self-evident that it's some kind of super poison. But it's not. Frankly, it's not always even clear what "it" is as there are thousands of different compounds, many of which people consume daily (e.g., flonase, prozac, etc). The health alarm around these substances is just astounding to me.
