Per- and polyfluoroalkyl substances (PFAS) in breast milk and infant formula: A global issue
Science
3 Jan 2023 | Environ. Res.
Breast milk concentrations of PFOA and PFOS often exceed children’s drinking water screening values, and limited information on infant formula means that families cannot generally know whether their infant’s exposures exceed safe levels.

Human serum poly- and perfluoroalkyl substance concentrations and their associations with gestational diabetes mellitus
Science
6 Dec 2022 | Environ Pollut
Higher serum PFAS concentrations were associated with gestational diabetes incidence in pregnant women, especially for PFOA, PFNA, PFHxS, and 6:2 Cl-PFESA.

Bayesian Estimation of Human Population Toxicokinetics of PFOA, PFOS, PFHxS, and PFNA from Studies of Contaminated Drinking Water
Science
1 Dec 2022 | Environ Health Perspect
A harmonized methodology was developed to determine the half-life and volume of distribution for PFOA, PFOS, PFNA, and PFHxS.

Bone mass density following developmental exposures to perfluoroalkyl substances (PFAS): a longitudinal cohort study
Science
19 Nov 2022 | Environ Health
PFAS exposures in childhood are negatively associated with overall bone mass density, with the strongest association seen for PFNA amongst 5-year-olds.

The effects of perfluoroalkyl and polyfluoroalkyl substances on female fertility: A systematic review and meta-analysis
Science
2 Nov 2022 | Environ Res
Increased levels of PFAS exposure are associated with reduced female fertility, which should be taken into account for risk assessments of manufacturing products containing PFAS.

Plasma concentrations of perfluoroalkyl acids and their determinants in youth and adults from Nunavik, Canada
Science
14 Oct 2022 | Chemosphere
Long-chain PFAAs levels were 4–7 fold higher in Nunavik Inuit adults compared to the Canadian population and were associated with hunting activity, omega-3 fatty acids, and drinking water from environmental sources.

Emerging contaminants migration from pipes used in drinking water distribution systems: a review of the scientific literature
Science
20 Sep 2022 | Environ Sci Pollut Res Int
PFOA, PFNA, PFDA, PFOS, and PFHxS were detected at levels indicating a potential non-carcinogenic health risk to consumers.

Drinking Water-Associated PFAS and Fluoroethers and Lipid Outcomes in the GenX Exposure Study
Science
7 Sep 2022 | Environ Health Perspect
PFNA and PFOS exposure through drinking water was associated with higher levels of total cholesterol, especially in older adults.

Association between fish oil supplements use and serum per- and polyfluoroalkyl substances (PFAS): Results from the National Health and Nutrition Examination Survey
Science
29 Aug 2022 | Environ Res
Fish oil supplement consumers did not have increased serum PFAS levels, specifically, but some inverse associations observed between the supplement use and PFOS levels in older adults and females need further study.

Associations of single and multiple perfluoroalkyl substances exposure with folate among adolescents in NHANES 2007-2010
Science
15 Aug 2022 | Chemosphere
Exposure to PFOS, PFOA, PFNA, and PFDA was associated with lower blood folate concentrations.

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.

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.
