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 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 ...
Examples include PFOA and PFOS, frequently present in water-resistant textiles and sprays conferring water-resistant properties to textiles and fire-fighting foam. [3] Data from animal studies of PFOA indicate that it can cause several types of tumors and neonatal death and may have toxic effects on the immune, liver, and endocrine systems.
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 ...
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 Devil We Know is a 2018 investigative documentary film by director Stephanie Soechtig regarding allegations of health hazards from perfluorooctanoic acid (PFOA, also known as C8), a key ingredient used in manufacturing Teflon, and DuPont's potential responsibility.
He believed the drink “was an ‘all natural’ juice beverage and thus was free of artificial, synthetic, and harmful chemicals like PFAS” but was deceived into buying it, the complaint says.
