Five biological replicates consisting of individual animals were included in each dosage group. There is evidence that perfluorooctane sulfonate (PFOS), which is an analogue chemical of PFOA, is globally distributed in humans9, 10) 1as well as wild life1, 12). In contrast, contaminations with PFOA have been observed in wild animals specific to some geographic areas12, 13). Similarly, geographical differences in serum PFOA levels Alibaba.com offers 39 potassium perfluorooctanesulfonate products.

DTXSID8037706 Perfluorooctanesulfonic acid is usually used as the sodium or potassium salts. PFOS was the key ingredient in Scotchgard , a fabric protector made by 3M , and numerous stain repellents. PFOS, together with PFOA , has also been used to make aqueous film forming foam (AFFF), a component of fire-fighting foams , and alcohol-type concentrate foams .

Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) November 2017 . Introduction This fact sheet, developed by the U.S. Environmental Protection Agency (EPA) Federal Facilities Restoration and Reuse Office (FFRRO), provides a summary of two contaminants of emerging concern, perfluorooctane
1Editor’s Note: This manuscript was accepted for publication on April 24, 2009. On May 9, 2009, the Conference of the Parties 4 of the Stockholm Convention (COP-4) in Geneva placed perfluorooctane sulfonate and perfluorooctane sulfonyl fluoride (PFOS and PFOSF) in Annex B (see below for other included substances). Perfluorooctane sulfonate, potassium salt (PFOS): a flow-through bioconcentration test with the bluegill (Lepomis macrochirus) - amended.
Perfluorooctane sulfonate (PFOS, potassium salt) was purchased from Fluka Chemical (Steinheim, Switzerland). The chemical was reported to be 91% pure by the supplier. Our analysis indicated that approximately 71% of the chemical was straight-chain, and the remaining 29% was branched.

Structural formula of PFOS shown as its potassium salt Synonyms: 1-Octanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro; 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-1-octanesulfonic acid; It breaks down to form perfluorooctane sulfonate (PFOS). The perfluorooctanesulfonyl fluoride -based chemistry that was used to make sulfonamides like PFOSA was phased out by 3M in the United States (US) during 2000–2002 but it has grown in China by other producers. PFOS is a perfluoralkyl sulfonate that is commonly used as a simple salt (such as potassium, sodium or ammonium) or is incorporated into larger polymers (EFSA 2008; EPA 2009c). PFOA is a perfluoralkyl carboxylate that is produced synthetically as a salt. Ammonium salt is the most widely produced form (EFSA 2008; EPA .
