Early-life exposure to per- and polyfluoroalkyl substances and infant gut microbial composition
Science
22 Feb 2023 | Environ Epidemiol
PFAS may increase infant gut microbiome diversity and alter the relative abundance of biologically relevant bacteria.

Exposure to serum perfluoroalkyl substances and biomarkers of liver function: The Korean national environmental health survey 2015-2017
Science
21 Feb 2023 | Chemosphere
Higher serum PFOA, PFOS, PFHxS, PFDA, and PFNA concentrations were related to higher serum concentrations of liver enzymes, although some differences were dependent on sex and obesity status.

Prenatal Exposure to Legacy and Alternative Per- and Polyfluoroalkyl Substances and Neuropsychological Development Trajectories over the First 3 Years of Life
Science
17 Feb 2023 | Environ Sci Technol
Mothers’ elevated serum levels of PFHxS, PFOS, and other PFAS mixtures were associated with decreased communication and problem-solving abilities throughout their children’s first 36 months of life.

Target and Nontarget Screening of PFAS in Drinking Water for a Large-Scale Survey of Urban and Rural Communities in Québec, Canada
Science
16 Feb 2023 | Water Res
99.3% of 463 tap water samples from Québec, Canada, had detectable levels of PFAS, including compounds not currently included in US EPA methods for drinking water testing.

EU floats plan that would ban virtually every PFAS currently on the market
News
9 Feb 2023 | Chemistry World
The five countries want to essentially ban the entire class of more than 10,000 chemicals in a single stroke, including their production, use, and sale, and the impact would be significant.

Systematic review and meta-analysis of epidemiologic data on vaccine response in relation to exposure to five principal perfluoroalkyl substances
Science
7 Feb 2023 | Environ Int
Serum PFAS concentrations may reduce antibody response after vaccination, especially for diphtheria, rubella, and tetanus.

Red blood cell folate modifies the association between serum per- and polyfluoroalkyl substances and antibody concentrations in U.S. adolescents
Science
30 Jan 2023 | Environ. Sci. Technol.
Associations between higher serum PFAS and lower disease antibodies were found to be significant only in adolescent groups with lower folate levels, suggesting that folate may be used as a mitigation measure against immune-related PFAS effects.

Leaching of Perfluoroalkyl Acids during Unsaturated Zone Flushing at a Field Site Impacted with Aqueous Film Forming Foam
Science
23 Jan 2023 | Environ Sci Technol
Remedial approaches that remove only a modest fraction of the PFAA mass in soil may be protective of underlying groundwater, particularly for some perfluorinated sulfonates.

Pennsylvania to limit PFAS in drinking water
Policy
14 Jan 2023
The new rule sets maximum contaminant levels in drinking water for two forms PFAS – in order to protect the public from potential adverse health effects linked to exposure to PFOA and PFOS.

Occurrence and implications of per and polyfluoroalkyl substances in animal feeds used in laboratory toxicity testing
Science
10 Jan 2023 | Sci Total Environ
PFAS contamination in animal feed was found to be pervasive, which is significant because unintended PFAS exposure in control animals from feed can significantly bias toxicity testing.
-
Associations between per and polyfluoroalkyl ether sulfonic acids and vitamin D biomarker levels in Chinese newborns
Science
5 Jan 2023 | Sci Total Environ
Exposure to legacy PFAS, including PFTrDA, PFHxS, and PFOS, might disturb vitamin D status in newborns.

Contact to perfluoroalkyl substances and thyroid health effects: A meta-analysis directing on pregnancy
Science
4 Jan 2023 | Chemosphere
A systematic review found that PFOS, PFOA, and PFDA exposures were associated with thyroid disruption in pregnant women, who were more sensitive to PFAS exposure in the first six months of pregnancy.
