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.
The EPA has determined that exposure to "certain levels of PFAS" could cause fertility issues and high blood pressure among women; impact childhood development; interfere with the body's natural ...
The risks of PFAS, sometimes known as "forever chemicals," have long been known. But it's more complicated than it sounds. Skip to main content. Subscriptions; Animals. Business. Fitness ...
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.
Per-and polyfluoroalkyl substances are found in thousands of products most Americans use or come into contact with daily, such as: Food containers that have PFAs are waterproof and grease-proof ...
Perfluorosulfonic acids (PFSAs) are chemical compounds of the formula C n F (2n+1) SO 3 H and thus belong to the family of perfluorinated and polyfluorinated alkyl compounds (PFASs).
The researchers discovered that all of the 13 bands that advertised that they were made from fluoroelastomers contained fluorine, which indicates the potential presence of PFAS. Two of the nine ...
PFAS accumulates in the body, which is why EPA set their limits for drinking water at 4 parts per trillion for two common types — PFOA and PFOS — that are phased out of manufacturing but still are present in the environment. Health experts say low doses of the chemicals can build up in the body over time, so even small amounts are a problem.
