Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is a chemical compound having an eight-carbon fluorocarbon chain and a sulfonic acid functional group, and thus it is a perfluorosulfonic acid and a perfluoroalkyl substance (PFAS).

The half-life of PFHxS in adult blood serum is 5.3 years (4.7 years for women and 7.4 years for men). [10] The half-life of PFASs in human blood generally decreases with decreasing backbone (CF 2) length. However, PFHxS is an unusual exception in that its half-life is greater than both longer and shorter chain equivalents such as PFOS or PFBS.
Costco members aren't afraid to speak up when a product from the warehouse club disappoints them, whether it's the consistently quick-spoiling produce or "poorly cut" filet mignon. Another Kirland ...
