Perfluorohexanesulfonic acid (PFHxS) (conjugate base perfluorohexanesulfonate) is a synthetic chemical compound. It is one of many compounds collectively known as per- and polyfluoroalkyl substances (PFASs). It is an anionic fluorosurfactant and a persistent organic pollutant with bioaccumulative properties.
The military is the most common culprit named among the 168 water systems that pointed to a PFAS source and also reported contamination above limits the EPA set earlier this year, USA TODAY's ...
The so-called “forever chemicals” − a name attributed to PFAS' centuries-long half-life − are ubiquitous: In addition to drinking water, they are found in everything from non-stick ...
Perfluorobutanesulfonic acid (PFBS) is a PFAS chemical compound having a four-carbon fluorocarbon chain and a sulfonic acid functional group. It is stable and unreactive because of the strength of carbon–fluorine bonds. It can occur in the form of a colorless liquid or a corrosive solid.
