Per-and polyfluoroalkyl substances in the atmosphere of waste management infrastructures: Uncovering secondary fluorotelomer alcohols, particle size distribution, and human inhalation exposure
Science
29 Jul 2022 | Environ. Int.
PFAS were prevalent in the air and in particulate matter near landfills and wastewater treatment plants, and modeling demonstrated that fine and ultrafine particles may carry PFAS into the lung alveoli.

Are cosmetics a significant source of PFAS in Europe? product inventories, chemical characterization and emission estimates
Science
21 Jul 2022 | Environ Sci Process Impacts
Annual European-wide cosmetic-related total fluorine and extractable organic fluorine emissions to wastewater and solid waste ranged from 17-38,000 kg F per year and 37-5100 kg F per year, respectively, representing a high emission source that is still lower than emissions from washing PFAS-coated textiles.
