Targeted analysis and total oxidizable precursor assay of several insecticides for PFAS
10 Oct 2022 | JHM Letters
PFOS was detected in 6 out of 10 tested insecticides at concentrations up to 19,200,000 ppt, with 7 additional PFAS found via non-targeted techniques.
An unexpected synergistic toxicity caused by competitive bioconcentration of perfluoroalkyl acid mixtures to Daphnia magna: Further promoted by elevated temperature
7 Oct 2022 | Environ Pollut
High temperatures promote the bioconcentration of PFAA and resulted in the increased toxicity of PFAA mixtures in model species.
An Integrated Approach for Determination of Total Per-and Polyfluoroalkyl Substances (PFAS)
5 Oct 2022 | Environ. Sci. Technol.
This paper describes how to use methods like the total oxidizable precursor assay and suspect screening to more fully characterize PFAS present in soil and aqueous mixtures as such screenings can help inform the potential for PFAS exposure.
Maternal Exposure to Per- and Polyfluoroalkyl Substances (PFAS) and Male Reproductive Function in Young Adulthood: Combined Exposure to Seven PFAS
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.
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.
Transdermal absorption of C-perfluorooctanoic acid (C-PFOA) from a sunscreen in a male volunteer - What could be the contribution of cosmetics to the internal exposure of perfluoroalkyl substances (PFAS)?
26 Sep 2022 | Environ Int
Using sunscreen containing PFOA resulted in an increase of a volunteer’s PFOA blood levels by about 10%.
