Per- and polyfluoroalkyl substances (also PFAS [1],PFASs [2], and sometimes referred to as "forever chemicals" [3] [4]) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million such chemicals according to PubChem. [5]
Chemicals like PFOS, PFOA and PFHxS are "for all intents and purposes correctly labeled as forever chemicals," said Christopher Higgins, a leading U.S. expert on PFAS and a distinguished professor ...
August 2000 In his research in preparation for the court case, Bilott found an article mentioning the "little-known substance"—a surfactant— called perfluorooctanoic acid (PFOA) or C8—had been found in DuPont's Dry Run Creek, adjacent to Tennant farm, and Bilott requested "more information on the chemical". This concerned DuPont's lawyer ...
Although the dangers of so-called forever chemicals are well-documented, these harmful substances have been detected in a range of personal care products used by consumers on a daily basis.
The wristbands were also checked for 20 different types of forever chemicals. Based on the findings, PFHxA was the most common, appearing in nine of the 22 tested wristbands.
Perfluorooctanoic acid (PFOA; conjugate base perfluorooctanoate; also known colloquially as C8, for its 8-carbon chain structure) is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock.
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.
Like the related chemicals hexaBDE, heptaBDE, and octaBDE (see below), hexabromodiphenyl is an endocrine disruptor. [30] Hexabromocyclododecane is a flame retardant predominately used in foams and textiles that is highly toxic to aquatic organisms. Human toxicology studies are ongoing, but it shows neuroendocrine disruption and developmental ...
