Childhood exposure to per-and polyfluoroalkyl substances and neurodevelopment in the CHARGE case-control study

12 Sep 2022 | Environ Res

Childhood PFOA, PFHpA, and a PFAS mixture were associated with increased odds of autism spectrum disorder.

PFAS concentrations and deposition in precipitation: An intensive 5-month study at National Atmospheric Deposition Program–National trends sites (NADP-NTN) across Wisconsin, USA

10 Sep 2022 | Atmos. Environ.

PFCAs were detected in 83% of rainwater samples, and differences in sites’ chemical profiles suggest that local PFAS sources can influence the PFAS collected in rain.

Associations of perfluoroalkyl and polyfluoroalkyl substances with gestational hypertension and blood pressure during pregnancy: A cohort study

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.

Drinking Water-Associated PFAS and Fluoroethers and Lipid Outcomes in the GenX Exposure Study

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.

Feeding and contaminant patterns of sub-arctic and arctic ringed seals: Potential insight into climate change-contaminant interactions

6 Sep 2022 | Environ. Pollut.

This paper demonstrates an important intersection between climate & toxics: that as climate change drives seals to consume different foods, their consumption of newer contaminants like PFAS may increase.

Distribution of Per-and Poly-fluoroalkyl Substances and Their Precursors in Human Blood

5 Sep 2022 | J. Hazard. Mater.

This study reports for the first time the partitioning of N-MeFOSA and N-EtFOSA in human blood.

A rapid assessment bioaccumulation screening (RABS) study design for emerging per-and polyfluoroalkyl substances in mice exposed to industrially impacted surface water

2 Sep 2022 | Chemosphere

A novel method was developed that can predict the bioaccumulation of PFAS mixture without chemical standards.

Glioma is Associated with Exposure to Legacy and Alternative Per-and Polyfluoroalkyl Substances

30 Aug 2022 | J. Hazard. Mater.

Higher concentrations of certain PFAS in brain tissue were associated with an increased risk of brain cancer.

Per- and polyfluoroalkyl substances exposure and its influence on the intestinal barrier: An overview on the advances

30 Aug 2022 | Sci Total Environ

This review summarizes current relationships between PFAS exposure and intestinal barrier damage and encourages further study to confirm the adverse effects of PFAS on the gastrointestinal tract.

Association between fish oil supplements use and serum per- and polyfluoroalkyl substances (PFAS): Results from the National Health and Nutrition Examination Survey

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.

Disparities in chemical exposures among pregnant women and neonates by socioeconomic and demographic characteristics: A nontargeted approach

29 Aug 2022 | Environ Res

Participants with higher socioeconomic status tended to have higher PFAS abundances.

Environmentally relevant concentrations of F-53B induce eye development disorders-mediated locomotor behavior in zebrafish larvae

29 Aug 2022 | Chemosphere

F-53B exposure was associated with irregular eye development, leading to vision loss in a human model species.

Raman imaging for the identification of Teflon microplastics and nanoplastics released from non-stick cookware

27 Aug 2022 | Sci. Total Environ.

Scratched non-stick cookware coatings may lead to release of millions of microplastic and nanoplastic particles that may contain Teflon.

Occurrence of Perfluoroalkyl and Polyfluoroalkyl Substances in Ice Cream, Instant Noodles, and Bubble Tea

23 Aug 2022 | J. Agric. Food Chem.

PFAS was detected at high concentrations in fast foods in China, especially after longer and hotter storage conditions, suggesting that PFAS exposure due to the consumption of bubble tea may be of concern.

Comparative toxicokinetics and toxicity of PFOA and its replacement GenX in the early stages of zebrafish

22 Aug 2022 | Chemosphere

At low levels, PFOA and GenX exhibited the same harmful acute effects on a human model species after accounting for differences in each chemical’s bioconcentration.
