Distribution and ten-year temporal trends (2009-2018) of perfluoroalkyl substances in gull eggs from Spanish breeding colonies
Science
30 Nov 2021 | Environ Pollut
Total PFAS concentrations in gull eggs decreased through the 10-year study period in all but one colony, highlighting the usefulness of gull eggs as bioindicators of PFAS pollution in water and fish.

Exposure to perfluoroalkyl substances was associated with estrogen homeostasis in pregnant women
Science
30 Nov 2021 | Sci Total Environ
Exposure to PFAS disturbed hormone levels in pregnant women and the effects varied with the time periods of exposure during pregnancy.

Species- and Tissue-Specific Chronic Toxicity Values for Northern Bobwhite Quail (Colinus virginianus) Exposed to PFHxA and a Binary Mixture of PFOS and PFHxA
Science
30 Nov 2021 | Environ Toxicol Chem
PFHxA was more toxic to reproducing birds than either PFOS or a PFOS:PFHxS mixture, suggesting that avian PFAS toxicity is not necessarily additive.

PFASs pollution in Galveston Bay surface waters and biota (shellfish and fish) following AFFFs use during the ITC fire at Deer Park (March 17th-20th 2019), Houston, TX
Science
30 Nov 2021 | Sci Total Environ
High PFAS levels were measured in water following AFFF usage on a nearby petrochemical fire and a risk assessment suggested a fish consumption advisory to protect against human exposure.

Distribution, source identification and health risk assessment of PFASs in groundwater from Jiangxi Province, China
Science
30 Nov 2021 | Chemosphere
Monitoring in China suggests that PFBA, PFPeA, 6:2 FTS and F–53B are broadly used replacements of PFOA and PFOS with estimated daily intakes of short-chain PFCAs higher than that of PFOA.

Per- and Poly-fluoroalkyl Substances (PFAS) and Female Reproductive Outcomes: PFAS Elimination, Endocrine-Mediated Effects, and Disease
Science
30 Nov 2021 | Toxicology
A summary of the role of PFAS in female reproductive dysfunction and disease is presented with the major data gaps, highlighting the importance for further study of the action mechanisms of PFAS harm in women.

Tumor and serum levels of per- and polyfluoroalkyl (PFAS) in hepatobiliary and gastrointestinal malignancy
Science
30 Nov 2021 | Am J Surg
Cancer patients had higher levels of PFOS than the national average and those with higher blood serum levels of PFOS were more likely to have higher levels of PFOS in tumors.

Maine found ‘forever chemicals’ in deer, but has no idea how widespread the problem is
News
24 Nov 2021 | Bangor Daily News
The discovery of “forever chemicals” in deer in central Maine and the subsequent guidance to not eat the meat raises serious questions about whether it is safe to consume venison killed in areas of the state where high levels of the chemicals have been detected or are suspected to exist.

[Opinion] COVID and PFAS: A match not made in heaven
News
24 Nov 2021 | NJ.com
Somewhat overlooked has been the actual effects of accumulation of per- and polyfluoroalkyl substances in our bodies, and there’s a new reason to study it.

Uptake of perfluoroalkyl substances, pharmaceuticals, and parabens by oyster mushrooms (Pleurotus ostreatus) and exposure risk in human consumption
Science
24 Nov 2021 | Chemosphere
Uptake of PFAS by oyster mushrooms was negatively correlated with perfluorocarbon chain length, and mushrooms grown in soil contaminated by PFAS may pose a risk if consumed.

Surface-water/groundwater boundaries affect seasonal PFAS concentrations and PFAA precursor transformations
Science
23 Nov 2021 | Environ Sci Process Impacts
Natural biogeochemical fluctuations associated with surface-water and groundwater boundaries may lead to PFAA precursor loss and seasonal variations in PFAA concentrations.

The driving factors of per- and polyfluorinated alkyl substance (PFAS) accumulation in selected fish species: The influence of position in river continuum, fish feed composition, and pollutant properties
Science
23 Nov 2021 | Sci Total Environ
Molecular mass and fluorine number play crucial roles in PFAS bioaccumulation in fish.

Impairment of human dopaminergic neurons at different developmental stages by perfluoro-octanoic acid (PFOA) and differential human brain areas accumulation of perfluoroalkyl chemicals
Science
23 Nov 2021 | Environ Int
In a proof-of-concept study, PFOA exposure was found to disrupt the most sensitive stage of neuron development.

Perfluorooctane sulfonate (PFOS) induces several behavioural defects in Caenorhabditis elegans that can also be transferred to the next generations
Science
23 Nov 2021 | Chemosphere
PFOS can exert severe neurobehavioral defects in locomotion, lifespan, and reproduction that can be transferred from parents to their offspring in a human model species.

What difference can drop-in substitution actually make? A life cycle assessment of alternative water repellent chemicals
Science
22 Nov 2021 | J. Clean. Prod.
A life cycle assessment found non-fluorinated durable water repellents for outdoor garments were environmentally preferable to fluorinated variants leading to the recommendation to phase out PFAS.
