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.

Increasing Accumulation of Perfluorocarboxylate Contaminants Revealed in an Antarctic Firn Core (1958–2017)
Science
26 Jul 2022 | ES&T
PFCA and PFBA accumulation in snow increased, and although chemical fluxes of PFOA and PFNA peaked in 2009–2013, there is little evidence of a decline in PFAAs despite supposed recent global curtailments in their production.

Adsorption of per-and polyfluoroalkyl substances (PFAS) to containers
Science
21 Jul 2022 | J. Hazard. Mater.
Containers used to hold PFAS mixtures adsorbed the chemicals at different rates based on PFAS chemistry, container hydrophobicity, temperature, and container manufacturer, with the general trend of PFAS adsorption as polypropylene > HDPE > PET > glass > polystyrene.
