Pfos chemical structure

The maker of Post-Its, 3M, a primary manufacturer of PFOS, voluntarily began phasing out the use of the chemical in 2000. PFCs are very stable, man-made chemicals. The chemical structure of PFCs is a chain of carbon atoms (4 to 16) surrounded by fluorine atoms and often with a charged functional group at the end (typically acarboxylate or sulfonate salt or acid). PFCs with 8 or greater Carbon atoms, including PFOA and PFOS, are long-chain PFCs.
