Preconception Exposure to Perfluoroalkyl and Polyfluoroalkyl Substances and Couple Fecundity: A Couple-Based Exploration

4 Oct 2022 | Environ. Int.

Preconception exposure to 6:2 diPAP and PFHpA in women may have the potential to impair couples’ fertility.

Uptake of per-and polyfluoroalkyl substances (PFAS) by soybean across two generations

3 Oct 2022 | J. Hazard. Mater. Adv.

Considering widespread PFAS contamination and the ability of soybean plants to uptake PFAS, soybean seeds may need to be quantified for PFAS concentrations before their use in agricultural fields.

[Letter to the editor] The conundrum of the PFOA human half-life, an international collaboration

1 Oct 2022 | RTP

Campbell et al. (2022) propose that many studies estimating the human half-life of PFOA are significantly confounded by lack of accounting for ongoing exposures, which would inflate estimates, and by the presence of branched isomers, which could deflate estimates for linear PFOA.

[Report] Groundwater Treatment to Remove PFAS: Restoring Local Drinking Water Supply in Orange County, California

1 Oct 2022 | AWWA

The design and implementation of water treatment technologies to remove PFAS from groundwater is described for the Orange County Water District in California.

Targeted and Suspect Screening of Per- and Polyfluoroalkyl Substances in Cosmetics and Personal Care Products

30 Sep 2022 | Environ Sci Technol

Cosmetics and personal care products were found to contain a breadth of PFAS at extremely high levels, including in products without listed fluorinated ingredients, leading to human and environmental exposure.

Association between prenatal exposure to perfluoroalkyl substances and anogenital distance in female neonates

28 Sep 2022 | Ecotoxicol Environ Saf

High maternal concentrations of PFAS were associated with abnormalities in female neonates, indicating that PFAS may impair reproductive development in female offspring in early life.

Evaluation of iodide chemical ionization mass spectrometry for gas and aerosol-phase per- and polyfluoroalkyl substances (PFAS) analysis

26 Sep 2022 | Environ Sci Process Impacts

A real-time method was developed to detect PFAS in the atmosphere in both the gas- and aerosol-phases, notably PFSAs and diPAPs.

Internal Relative Potency Factors for the Risk Assessment of Mixtures of Per- and Polyfluoroalkyl Substances (PFAS) in Human Biomonitoring

26 Sep 2022 | EHP

It is recommended to assess the health risk resulting from exposure to PFAS as combined, aggregate exposure to the extent feasible.

Per- and Polyfluoroalkyl Substances in North American School Uniforms

21 Sep 2022 | ES&T

High PFAS levels in school uniforms could be an important source of PFAS exposure for children.

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.
