The type of PFAS remediation technology selected is often a reflection of the PFAS contamination levels and the PFAS signature (i.e. the combination of short- and long-chain PFAS substances present) in conjunction with the site-specific water chemistry and cross contaminants present in the liquid stream.
Remediation of per- and polyfluoroalkyl substances refers to the destruction or removal of per- and polyfluoroalkyl substances (PFASs) from the environment. PFASs are a group of synthetic organofluorine compounds, used in diverse products such as non-stick cookware and firefighting foams, that have attracted great concern as persistent organic pollutants.
Called “forever chemicals” because of how long they remain in the human body and environment, perfluoroalkyl and polyfluoroalkyl substances, or PFAS, are a growing health concern.
Called forever chemicals because they never break down in the environment, PFAS can take years to completely leave the body, according to a 2022 report by the prestigious National Academies of ...
Trifluoroacetic acid is a widely employed acid, used for example in the synthesis of peptides.Its esters are useful in analytical chemistry. Longer-chain perfluoroalkyl carboxylic acids, e.g. with five to nine carbons, are useful fluorosurfactants and emulsifiers used in the production of polytetrafluoroethylene (Teflon) and related fluoropolymers.
PFAS has been found in almost all human blood samples tested, one study found 97% of Americans has PFAS in their blood. [27] PFAS chemicals have been linked to high cholesterol, [ 28 ] altered kidney and thyroid function, [ 29 ] ulcerative colitis, [ 30 ] immunosuppression, [ 31 ] decreased effectiveness of vaccines, [ 32 ] low birth weight ...
Called "forever chemicals" because they bioaccumulate in the environment and don't break down in the body once consumed, PFAS (which stands for perfluoroalkyl and polyfluoroalkyl substances) have ...
Perfluorosulfonic acids with six or more perfluorinated carbon atoms, i.e. from perfluorohexanesulfonic acid onwards, are referred to as long-chain. [1] Perfluorooctanesulfonic acid Trifluoromethanesulfonic acid
