Manufacturers in the metal coatings market are also focusing on designing new products to address concerns associated with perfluorooctanesulfonic acid and perfluorooctanoic acid
found in many fluoropolymer chemicals.
Environmental Protection Agency (USEPA) Lifetime Health Advisory (LHA) of 70 ppt for perfluorooctanoic acid
(PFOA) and perfluorooctanesulfonic acid (PFOS) individually or combined in drinking water.
Johnson said now the agencies can look into the future of environmental restoration together and have a unified response specifically to the emerging contaminants, perfluorooctane sulfonate and perfluorooctanoic acid
According to the complaint, various manufacturers and sellers created, advertised, and sold aqueous film-forming foam products containing chemicals known as perfluorooctane sulfonic acid, or PFOS, and perfluorooctanoic acid
, or PFOA.
Dicofol and Perfluorooctanoic Acid
, plus related compounds.
However, repelling agents have had a history of sustainability issues because of their potential to break down and form perfluorooctanoic acid
Collectively known as PFAS, the group includes perfluorooctanoic acid
(PFOA), perfluoroc-tanesulfonic acid (PFOS), GenX and many other chemicals commonly used in food packaging, carpeting, stain- and water-resistant clothing, nonstick products and firefighting foams.
(PFOA) exposures and incident cancers among adults living near a chemical plant.
Featuring OGR levels ranging from Kit 5 to as high as Kit 12, GlazeArmor NK OGR and GlazeArmor NK Micro are Perfluorooctanoic acid
(PFOA)-free and are designed to work well in low to high oil and grease end uses.
Although several PFAs such as perfluorooctane sulfonate (PFOS), perfluorooctanoic acid
(PFOA), perfluorohexane sulfonate (PFHxS), and perfluorononanoic acid (PFNA) have been more widely studied, research has not yet determined the health effects and mechanisms resulting from human exposure to PFAs at levels typically found in water and food [14, 15].
Those chemicals include perfluorooctanoic acid
(PFOA), which is used to add extra flexibility to plastic.
The chemicals - perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid
(PFOA) - were developed in the early 1950s by the corporate giant 3M and are used to provide resistance to heat, or for dispersion, wetting and surface treatments.
