Association between per- and polyfluoroalkyl substances exposure and risk of diabetes: a systematic review and meta-analysis
Science
15 Aug 2022 | J Expo Sci Environ Epidemiol
Exposure to PFAS may increase diabetes risk among the general population, and PFOA may exert a non-monotonic dose-response effect on diabetes risk.

Exposure to perfluoroalkyl substances and risk of hepatocellular carcinoma in a multiethnic cohort
Science
8 Aug 2022 | JHEP Reports
Exposure to high PFOS levels was associated with an increased risk of non-viral liver cancer, likely via alterations in glucose, amino acid, and bile acid metabolism.

Influence of microplastics on the photodegradation of perfluorooctane sulfonamide (FOSA)
Science
8 Aug 2022 | Res. J. Environ. Sci.
Microplastics could act as PFAS concentrators, making the PFAS more resistant to degradation.

Pollution: 'Forever chemicals' in rainwater exceed safe levels
News
2 Aug 2022 | BBC
New research shows that rainwater in most locations on Earth contains levels of chemicals that "greatly exceed" safety levels.

Outside the Safe Operating Space of a New Planetary Boundary for Per-and Polyfluoroalkyl Substances (PFAS)
Science
2 Aug 2022 | ES&T
PFAS have been detected at unsafe levels in rain globally, leading to the conclusions that the spread of PFOS, PFOA, PFHxS, and PFNA in the atmosphere has exceeded levels of concern for chemical pollution and that PFAS uses and emissions should be rapidly restricted.

The PFAS-Tox Database: A systematic evidence map of health studies on 29 per- and polyfluoroalkyl substances
Science
1 Aug 2022 | Environ. Int.
In this summary of the PFAS-Tox Database we provide examples of data gaps and clusters revealed by the database, with the goal of helping direct future research efforts, facilitate systematic reviews (e.g. on immune effects, mixtures of PFAS, or effects of short chain PFAS), inform regulatory risk assessments, and improve opportunities for cross-disciplinary coordination.

Rhode Island PFAS Regulations Become Law
Policy
1 Aug 2022
On June 27, 2022, Rhode Island passed two new laws into effect that regulate six types of PFAS in food packaging, drinking water, ground water, surface waters, and landfills.

Uptake of individual and mixed per- and polyfluoroalkyl substances (PFAS) by soybean and their effects on functional genes related to nitrification, denitrification, and nitrogen fixation
Science
29 Jul 2022 | Sci. Total Environ.
The synergistic effect of a PFAS mixture increased the uptake of individual PFAS in soybeans, which led to changes in genes involved in the nitrogen cycle.

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.

Extensive wildlife testing for PFAS could result in more ‘do not eat’ advisories
News
25 Jul 2022 | Bangor Daily News
Nearly eight months after the Maine Department of Inland Fisheries and Wildlife issued a ‘do not eat’ advisory for deer harvested in Fairfield because of the presence of PFAS, the department will return to the area.

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.

Occurrence and Fate of Ultrashort-Chain and Other Per-and Polyfluoroalkyl Substances (PFAS) in Wastewater Treatment Plants
Science
19 Jul 2022 | ACS ES&T Water
The transformation of precursors into shorter chain PFAAs by biological treatment and the partitioning of longer chain PFAS into sludge streams are key factors determining the fate of PFAS in wastewater treatment plants.
