It was not until the early 1990s that the toxic effects of PFOA became a public concern. Wilbur Tennant, a farmer who lives on his own private land near the DuPont plant in Parkersburg, West Virginia, videotaped the calamitous effects of PFOA on his cattle and local wildlife. Calves were born with black teeth and opaque eyes.
[54] [55] These results were consistent with the measured serum concentrations of PFOS and PFOA in 3M plant workers ranging from 0.04 to 10.06 ppm and 0.01 to 12.70 ppm, respectively, well below toxic and carcinogenic levels cited in animal studies. [55]
Early 2018 Department of Health & Human Services's Agency for Toxic Substances and Disease Registry (ATSDR) was about to publish its assessment of PFAS chemicals, with a focus on two specific chemicals from the PFAS class—PFOA and PFOS—that have "contaminated water supplies near military bases, chemical plants and other sites from New York ...
Two of the most common types (PFOS and PFOA) were phased out of production in the United States (US) in 2002 and 2015 respectively, but are still present in some imported products, and were replaced by the similarly toxic GenX in Teflon products. PFOA and PFOS are found in every American person’s blood stream in the parts per billion range ...
Perfluorooctanoic acid (PFOA; conjugate base perfluorooctanoate; also known colloquially as C8, for its 8-carbon chain structure) is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock.

For the most toxic houseplants, it’s smart to keep them out of reach of pets or out of your home completely, says Dr. Wismer. Ditto for toxic landscape plants; either fence them or don't plant them.
PFOA persists indefinitely in the environment. It is a toxicant and carcinogen in animals. PFOA has been detected in the blood of more than 98% of the general US population in the low and sub-parts per billion (ppb) range, and levels are higher in chemical plant employees and surrounding subpopulations.
