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]
The risks of PFAS, sometimes known as "forever chemicals," have long been known. But it's more complicated than it sounds.
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 ...
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.
Phthalates, substances categorized as "forever chemicals," have been found in nearly every American's bloodstream, coming from the cleaning products they use to the food and drinks they consume.
Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur. The substance (or substances) initially involved in a chemical reaction are called reactants or reagents .
At baseline, perfluorohexanoic acid is a forever chemical. That means it can build up in the body, with Peaslee noting that perfluorohexanoic acid “bioaccumulates” in the blood.
The requirements cover the so-called "forever chemicals" — perfluoroalkyl and polyfluoroalkyl substances. The chemicals, known as PFAS and PFOS, have settled in the water and environment after ...
