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.

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.
