U.S. Department of Defense-Funded Fate and Transport Research on Per- and Polyfluoroalkyl Substances at Aqueous Film-Forming Foam-Impacted Sites

26 Feb 2020 | Environ. Tox. and Chem.

This article summarizes much of the work the U.S. Department of Defense has conducted over PFAS fate and transport and their overarching conclusions to date.

Release of Volatile Per- and Polyfluoroalkyl Substances from Aqueous Film-Forming Foam

26 Feb 2020 | Environ Sci Technol. Let.

PFAS was found to be dispersed in the air when used in aqueous film-forming foam, potentially putting firefighters at risk.

Serum Levels of Perfluoroalkyl Substances (PFAS) in Adolescents and Young Adults Exposed to Contaminated Drinking Water in the Veneto Region, Italy: A Cross-Sectional Study Based on a Health Surveillance Program.

26 Feb 2020 | Environ. Health Perspect.

Tissue distribution and bioaccumulation of 8:2 fluorotelomer alcohol and its metabolites in pigs after oral exposure

25 Feb 2020 | Chemosphere

PFOA and PFHpA were found to bioaccumulate in the kidney and heart respectively.

Field Sampling Materials Unlikely Source of Contamination for Perfluoroalkyl and Polyfluoroalkyl Substances in Field Samples

25 Feb 2020 | Environ. Sci. & Tech. Let.

Sixty-six common materials used to sample and analyze for PFAS were found not to be a significant source of PFAS contamination in field samples.

Exposure to PFAS and small for gestational age new-borns: A birth records study in Veneto Region (Italy)

25 Feb 2020 | Enviro. Res.

PFAS was associated with significantly decreased birth weight and size in newborns.

Epigenetic toxicity of PFOA and GenX in HepG2 cells and their roles in lipid metabolism.

25 Feb 2020 | Toxicol In Vitro

PFOA was found to induce higher levels of liver damage than GenX.

Comparative analysis of the toxicological databases for 6:2 fluorotelomer alcohol (6:2 FTOH) and perfluorohexanoic acid (PFHxA).

25 Feb 2020 | Food Chem. Toxicol.

This article summarizes a comparative analysis of the toxicological effects of PFHxA and 6:2 FTOH and finds that 6:2 FTOH is significantly more toxic than PFHxA.

Chronic PFAS-exposure under environmentally relevant conditions delays development in northern leopard frog (Rana pipiens) larvae.

25 Feb 2020 | Environ. Toxicol. Chem.

Developmental delays were seen at levels as low as 0.06 ppb in frogs.

Model-based analysis of the uptake of perfluoroalkyl acids (PFAAs) from soil into plants

19 Feb 2020 | Chemosphere

A model was used to determine PFAS movement in the stem and fruit in red chicory.

Origin and organ-specific bioaccumulation pattern of perfluorinated alkyl substances in crabs

19 Feb 2020 | Environ. Poll.

PFOA was dominant among the PFAS in Korean and Chinese crabs, and PFOS was dominant among Pakistani and Indian crabs.

Determinants of serum concentrations of perfluoroalkyl acids (PFAAs) in school children and the contribution of low-level PFAA-contaminated drinking water

18 Feb 2020 | Environ Sci Process Impacts

The drinking water variable was found to be 16% (PFOA) to 78% (PFHxS) of the variation in serum PFAA concentrations, suggesting that low-level-contaminated drinking water is a significant source of exposure for children in Sweden.
