Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are fluorinated hydrocarbons used as water-, oil-, and stain-resistant coatings in fabrics, leather, and carpets, and oil-resistant coatings for paper products for food contact, and also as photographic emulsifier, aviation hydraulic fluids, and fire-fighting foams.

Prior toxicological studies have reported decreased total and free thyroid hormones in serum without a major compensatory rise in thyrotropin (TSH) or altered thyroid gland histology. Perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) are among the most prominent contaminants in human serum, and these were historically manufactured as technical mixtures of linear and branched isomers.

2019-03-01 · Perfluoroalkyl substances (PFASs) are widely-utilized synthetic chemicals commonly found in industrial and consumer products. Previous studies have examined associations between PFASs and renal function, yet the results are mixed.

Perfluoroalkyls are stable, synthetic chemicals. Perfluoroalkyls are unique because they repel oil, grease, and water.The two perfluoroalkyls made in the largest amounts in the U.S. are perflurooctanoic acid and perfluorooctane sulfonic acid (PFOS).Perfluoroalkyls have been used in surface protection products such as carpet and clothing treatments and coating for paper and cardboard packaging.

Abstract Perfluorooctanesulfonate (PFOS) is a man-made chemical widely used in industrial products.

PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009.

Sorption of PFOS isomers on goethite as a function of pH, dissolved organic trials for analysis of perfluorooctanesulfonate and perfluorooctanoate in water

Understanding the mechanisms controlling the distribution of PFOS and its isomers between hydrargillite and the water phase is important in order to study their redistribution and mobility in the environment.
