imperfectionisperfectionword of the day: PFAS
an amazingly rich scientific article, i recommend the whole thing. maybe. i only read the first 2 meningarna. but its so nice and so critical to this bullshit. this is what science is supposed to be about. and peer review.
btw, in 1 place it says its "carbon flouride". here it says "alcohol flouride". but its really lead flouride. ethyl is liquid lead.
Per- and polyfluoroalkyl substances (also PFAS,[1] PFASs,[2] and informally 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 known such chemicals according to PubChem.[5] PFAS came into use with the invention of Teflon in 1938 to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. They are now used in products including waterproof fabric such as nylon, yoga pants, carpets, shampoo, feminine hygiene products, mobile phone screens, wall paint, furniture, adhesives, food packaging, firefighting foam, and the insulation of electrical wires.[6][7][8] PFAS are also used by the cosmetic industry in most cosmetics and personal care products, including lipstick, eye liner, mascara, foundation, concealer, lip balm, blush, and nail polish.[9][10]
Many PFAS such as PFOS and PFOA pose health and environmental concerns because they are persistent organic pollutants; they were branded as "forever chemicals" in an article in The Washington Post in 2018.[11] Some have half-lives of over eight years in the body, due to a carbon-fluorine bond, one of the strongest in organic chemistry.[12][13][14][15][16] They move through soils and bioaccumulate in fish and wildlife, which are then eaten by humans. Residues are now commonly found in rain, drinking water, and wastewater.[12][17][18][7] Since PFAS compounds are highly mobile, they are readily absorbed through human skin and through tear ducts, and such products on lips are often unwittingly ingested.[19] Due to the large number of PFAS, it is challenging to study and assess the potential human health and environmental risks; more research is necessary and is ongoing.[20][12][21][6]
