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. This includes data values and the controlled vocabularies that house them.

Transplacental exposure of neonates to perfluorooctanesulfonate and perfluorooctanoate: a pilot. Temporal trends of perfluorooctanesulfonate isomer and enantiomer patterns in archived Swedish and American serum samples.

Perfluorooctane sulfonate (PFOS), one of the main PFCs, has been widely detected in humans, wildlife, and various environmental media , , . Concentrations of PFOS in water environment typically vary widely, often by several orders of magnitude.

Objectives. Perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) can be released of perfluorinated compounds by biotic and/or metabolic decomposition. Due to their ubiquitous occurrence, persistence and bioaccumulative properties they can be found in blood of the general population all over the world.

Perfluorooctane sulfonate (PFOS), one of the main PFCs, has been widely detected in humans, wildlife, and various environmental media , , . Concentrations of PFOS in water environment typically vary widely, often by several orders of magnitude.

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. 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.

*C8F17NaO3S. Unlabeled CAS#. 4021-47-0. Labeled CAS#. PFOA has been used in the manufacture of fluoropolymers such as polytetrafluoroethylene (i.e., Teflon) since the 1940s. PFOS exhibits similar properties and, like PFOA, has been used in a variety of consumer products (e.g., Scotchgard) for its stain-, grease- and water-resistant properties.
