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.

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.

Changes in perfluoroalkyl substances (PFAS) concentrations in human milk over the course of lactation: A study in Ronneby mother-child cohort
Science
15 Dec 2022 | Environ Res
PFOA concentrations in breast milk decreased over the course of lactation by 12% per month, while PFOS and PFHxS showed small changes.

Emerging Contaminants and New POPs (PFAS and HBCDD) in Endangered Southern Resident and Bigg’s (Transient) Killer Whales (Orcinus orca): In Utero Maternal Transfer and Pollution Management Implications
Science
13 Dec 2022 | ACS
7:3-fluorotelomer carboxylic acid was the primary PFAS detected in killer whales' skeletal muscle and liver samples in the Northeastern Pacific Ocean, followed by PFOS, PFOA, and PFHxS.

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.

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.

Maternal Exposure to Per- and Polyfluoroalkyl Substances (PFAS) and Male Reproductive Function in Young Adulthood: Combined Exposure to Seven PFAS
Science
5 Oct 2022 | Environ Health Perspect
Consistent inverse associations between exposure to maternal PFAS and semen quality were found in a sample of the Danish population.

First report on per- and polyfluoroalkyl substances (PFASs) in coral communities from the Northern South China sea: Occurrence, seasonal variation, and interspecies differences
Science
20 Sep 2022 | Environ Pollut
PFHxS accounted for 43% of total PFAS detected in corals with short-chain PFAS concentrations higher than legacy PFAS, though concentrations depended on seasonal factors and coral type.

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) crossing the blood-cerebrospinal fluid barrier: Their occurrence in human cerebrospinal fluid
Science
15 Sep 2022 | J Hazard Mater

Associations of perfluoroalkyl and polyfluoroalkyl substances with gestational hypertension and blood pressure during pregnancy: A cohort study
Science
8 Sep 2022 | Environ Res
Higher concentrations of PFAS during early pregnancy were associated with lower gestational hypertension risk and reduced blood pressure measures in the third trimester in a population with relatively high exposure levels.
