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.
Most measurements of PFAS in humans are made with serum, a fluid derived from blood but without coagulants or red blood cells, which requires the presence of a medical professional, said Stapleton ...
The USA TODAY Network maintains full editorial control of the work. This article originally appeared on Wilmington StarNews: Why GenX and PFAS are back in the news and what it means for NC Show ...
PFAS tests that claim to offer results within minutes or at home should be avoided, according to Canter and Professor Mark D. Krahling, an analytical chemist at the University of Southern Indiana ...
PFDA is a member of the group of polyfluoroalkyl substances (PFAS), more specific is it also a perfluoroalkyl acid (PFAA). PFAS, like PFDA, are man-made and are not naturally occurring in nature. Over the last decades they have been used in consumer products and industrial applications.
A new EU drinking water directive issued in 2020 adopted PFAS limit values. The limit values are 0.1 μg/L for the sum of 20 PFASs including PFHxS, and 0.5 μg/L for the sum of all PFASs. This directive is binding for all EU member nations. It is a minimum directive, and member states can elect to adopt stricter regulations. [19]
The PFAS pesticides are also used in flea treatments for pets and insect-killing sprays in homes, according to the research conducted by scientists at EWG, the Center for Biological Diversity in ...
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. [1]
