Sales of PFAS, which cost approximately $20 per kilogram, generate a total industry profit of $4 billion per year on 16% profit margins. [29] Due to health concerns, several companies have ended or plan to end the sale of PFAS or products that contain them; these include W. L. Gore & Associates (the maker of Gore-Tex), H&M, Patagonia, REI, and 3M.
There are no health advisories for PFAS chemicals in Mexico. One kind of PFAS in firefighters' gear, called fluorotelomer alcohols, does break down in the environment. They are precursors to PFOA ...
There are chemicals in cookware, food, water, clothes and furniture that could cause problems for people’s health. These PFAS, or perfluoroalkyl and polyfluoroalkyl substances — sometimes ...
Researchers have linked exposure to some PFAS compounds to serious health conditions. Two of the primary compounds of concern, PFOA and PFOS, pose a host of potential risks, particularly to ...
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]
All of these methods promote the formation of hydroxyl radicals or other oxidizing agents that can oxidize PFAS and break its C−C bonds. [3] [4] However, the remediation of PFAS depends on the environmental medium where the these compounds reside. For example, the treatment of contaminated soil, biosolids and water is not the same, and risk ...
How to avoid PFAS. Avoiding the health consequences of PFAS exposure requires both systemic change and making adjustments in one’s own daily behavior. “Prevention is the only way to reduce ...
Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is a chemical compound having an eight-carbon fluorocarbon chain and a sulfonic acid functional group, and thus it is a perfluorosulfonic acid and a perfluoroalkyl substance (PFAS). It is an anthropogenic (man-made) fluorosurfactant, now regarded as a global pollutant.
