Waxing activity as a potential source of exposure to per- and polyfluoroalkyl substances (PFAS) and other environmental contaminants among the US ski and snowboard community
20 Sep 2022 | Environ Res
The majority of winter sports enthusiasts use PFAS-containing waxes and solvents with minimal exposure interventions, suggesting the need for further investigation into wax-related PFAS exposure.
First report on per- and polyfluoroalkyl substances (PFASs) in coral communities from the Northern South China sea: Occurrence, seasonal variation, and interspecies differences
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.
Emerging contaminants migration from pipes used in drinking water distribution systems: a review of the scientific literature
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.
Characterization of per-and polyfluoroalkyl substances on fire suppression system piping and optimization of removal methods
19 Sep 2022 | Chemosphere
Fire suppression systems accumulate residual PFAS in pipe surfaces due to AFFF use, and new fluorine-free foam can be contaminated with PFAS if the systems are not properly cleaned.
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) crossing the blood-cerebrospinal fluid barrier: Their occurrence in human cerebrospinal fluid
15 Sep 2022 | J Hazard Mater
New and legacy PFAS were found cerebrospinal fluid at levels lower than in blood, though levels were higher in the elderly compared with other age groups.
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.
