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.
