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.
In order to detach their name from the toxic reputation of PFOA's, DuPont created the spin-off company, Chemours, to handle production and continued dumping of Gen-X. [2] After facing several class-action lawsuits, DuPont paid $43,000 residents of Ohio each $400 to participate in a study to determine whether C8 could be linked to any diseases.
A substance which could cause cancer has been found on the former grounds of a Lancashire chemical plant. ... "Everyone in the country is exposed to very low levels of PFOA due to their diet.
[53] [54] 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. [54]
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 ...
The state added PFOA to its Proposition 65 list of chemicals that are known to cause reproductive toxicity in 2017 and to the list known to cause cancer in 2022. But it's one of only around a ...
The limit for two of the most common types of forever chemicals, known as PFOA and PFOS, is 4 parts per trillion, with a handful of others now limited to 10 parts per trillion.
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.
