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.
“Since intact skin acts as an effective barrier to many toxins, it’s unlikely that people will absorb a significant amount of perfluorohexanoic acid — or other PFAS chemicals — through the ...
In 2008, products containing PFOS as well as PFOA were banned in Canada, with exceptions for products used in firefighting, the military, and some forms of ink and photo media.

It is used as a defense against herbivores by at least 40 green plants in Australia, Brazil, and Africa; [43] other biologically synthesized organofluorines include ω-fluoro fatty acids, fluoroacetone, and 2-fluorocitrate. [50] In bacteria, the enzyme adenosyl-fluoride synthase, which makes the carbon–fluorine bond, has been isolated. The ...
