The proposal has not assessed the use of PFAS in medicines, plant protection products, and biocides because specific regulations apply to those substances (Biocidal Products Regulation, Plant Protection Products Regulation, Medicinal Products Regulation) that have an explicit authorization procedure that focuses on risk for health and the ...
Long-chain PFAS chemicals perfluorooctane sulfonic acid, or PFOS, and perfluorooctanoic acid, or PFOA, are among the most studied of the nearly 15,000 types of PFAS used by industry.
Flowers (in full bloom, June or early July). A tea (popular in France as tilleul) can be made from the dried flowers. Leaves, without the stalks, edible raw as a salad vegetable [33] Wild lowbush blueberry Vaccinium angustifolium: Eastern and central Canada, northeastern United States Berries, edible raw, commonly used in jams and jellies [34]
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 .
Story at a glance A group of potentially harmful chemicals called per- and polyfluoroalkyl substances (PFAS) have repeatedly cropped up in headlines. But the sheer number of chemicals in this ...

Fire-retardant foam, which contained PFAS compounds for decades, often found use at military bases and airstrips, causing costly pollution to nearby water sources. The U.S. Department of Defense ...
Perfluorooctanesulfonic acid is usually used as the sodium or potassium salts. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. PFOS, together with PFOA, has also been used to make aqueous film forming foam (AFFF), a component of fire-fighting foams, and alcohol-type concentrate foams.
