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.
Skeletal structure of PFOS, an effective, persistent and bioaccumulative fluorosurfactant A physical sample of PFOA, appearing as a white solid as seen here in a relatively pure form. It is commonly referred to as the main harmful PFAS chemical and PFOA is responsible for many of the negative health effects commonly associated with PFAS.
The Swedish National Food Agency recommends a drinking water limit of 0.09 μg/L for the sum of 11 PFASs (PFBS, PFHxS, PFOS, 6:2 FTSA, PFBA, PFPeA, PFHxA, PFHpA, PFOA, PFNA and PFDA). If PFASs are found above this limit in drinking water, immediate action is recommended to reduce the PFAS concentration in the drinking water to as far below the ...
In 1968, organofluorine compounds were detected in the blood serum of consumers, and in 1976, perfluorooctanoic acid (PFOA) or a related compound such as PFOS were suggested as components. [ 6 ] [ 7 ] [ 8 ] In 1997, 3M detected PFOS in blood from global blood banks, [ 9 ] although the company's internal documents indicate knowledge of this ...

However, in a December 2005 deal with the USEPA over alleged withholdings, DuPont agreed to test nine of its fluorotelomer-based products' potential to break down into PFOA by 27 December 2008. [17] Yet, in late December 2008, the USEPA and DuPont filed a joint motion stating that DuPont needed additional time [17] to purify the products. [7]
