Perfluorooctanesulfonate (PFOS) is a compd. of global concern because of its persistence and bioaccumulation in the environment. Nevertheless, little is known of the potential for PFOS biodegrdn., even though the importance of characterizing the function and activity of microbial populations detected in the environment was discussed. Perfluorooctanoate (PFOA) and perfluorooctanesulfonate (PFOS) are synthetically produced chemicals, which are used in a range of industries and consumer products as surfactants, due to their water- and oil-resistant properties. 1 From a public health perspective, however, concern was raised when the compounds were found to be ubiquitously present in the environment due to their persistent nature. The Linked Data Service provides access to commonly found standards and vocabularies promulgated by the Library of Congress.

Chemical compound. Perfluorooctanesulfonamide ( PFOSA) is a synthetic organofluorine compound. It is a fluorocarbon derivative and a perfluorinated compound, having an eight-carbon chain and a terminal sulfonamide functional group.

Perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) are fluorinated organic compounds present in the general population at low concentrations. Animal studies have shown that they may affect neuromuscular development at high concentrations.

It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009. PFOS can be synthesized in industrial production or result from the degradation of precursors. PFOS levels that have been detected in wildlife are considered high enough to affect health perfluorooctanesulfonate.

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. Perfluoroctansulfonsäure (Anion Perfluoroctansulfonat oder kurz PFOS) ist eine chemische Verbindung aus der Gruppe der per- und polyfluorierte Alkylverbindungen (PFAS). United States Office of Land and Emergency EPA 505-F-17-001 Environmental Protection Agency Management (5106P) November 2017 1 Technical Fact Sheet – 2021-04-14 · In 2000 several member countries agreed to informally work together to collect information on the environmental and human health hazards of perfluorooctane sulfonate (PFOS) to produce a hazard assessment. The decision followed the announcement by a major US manufacturer (3M) to globally phase out 1H,1H,2H,2H-PERFLUOROOCTANE SULFONATE (6:2 FTS), SODIUM SALT (13C2, 99%; D4, 98%) 50 UG/ML IN MEOH. * For isotopically labeled compounds, MW listed is for the fully enriched product.
