A systematic evidence map of chronic inflammation and immunosuppression related to per-and polyfluoroalkyl substance (PFAS) exposure

30 Dec 2022 | Environ Res

Several PFAS commonly found in the environment may induce immunosuppression and chronic inflammation, two key characteristics of carcinogens.

Concentrations of Per- and Polyfluoroalkyl Substances in Paired Maternal Plasma and Human Milk in the New Hampshire Birth Cohort

27 Dec 2022 | Environ Sci Technol

Maternal PFOA and PFOS serum concentrations correlated with milk concentrations, and while milk concentrations were lower, about 6.5% of infants were estimated to be exposed to enough PFAS via milk to have long-term health impacts.

Locally caught freshwater fish across the United States are likely a significant source of exposure to PFOS and other perfluorinated compounds

27 Dec 2022 | Environ Res

PFAS are widely detected in freshwater fish across the United States at very high concentrations and fish may be a main source of exposure, especially for communities that depend on fish for sustenance and traditional cultural practices. For example, PFOS exposure from one average serving of freshwater fish is equivalent to one month of exposure from drinking water with 48 ppt PFOS.

Perfluoroalkyl substances exposure in firefighters: Sources and implications

27 Dec 2022 | Environ Res

This article summarizes the history of AFFF use by firefighters and describes PFAS exposure and removal pathways, PFAS accumulation in blood serum of firefighters, and occupational factors affecting PFAS levels in firefighters, all of which may influence how firefighters have elevated risks of developing thyroid, kidney, testicular, and prostate cancer.

Does Using Corsi–Rosenthal Boxes to Mitigate COVID-19 Transmission Also Reduce Indoor Air Concentrations of PFAS and Phthalates?

23 Dec 2022 | ES&T

Inexpensive, DIY HEPA filtration systems traditionally used to reduce harms from COVID and air pollution were found to also reduce PFAS and phthalate exposure in university buildings.

Perfluoroalkyl Substance Serum Concentrations and Cholesterol Absorption-Inhibiting Medication Ezetimibe

19 Dec 2022 | toxics

A medication that inhibits cholesterol absorption did not appear to affect serum PFAS concentrations, suggesting that inter-individual sterol absorption differences do not provide a confounding factor explanation for the known association between serum cholesterol and serum PFAS.

Accumulation and transport of atmospherically deposited PFOA and PFOS in undisturbed soils downwind from a fluoropolymers factory

19 Dec 2022 | Adv. Environ.

PFAS contaminates soil in urban, industrialized areas through atmospheric deposition, where it can penetrate through the soil and pollute groundwater.

Changes in perfluoroalkyl substances (PFAS) concentrations in human milk over the course of lactation: A study in Ronneby mother-child cohort

15 Dec 2022 | Environ Res

PFOA concentrations in breast milk decreased over the course of lactation by 12% per month, while PFOS and PFHxS showed small changes.

[Perspective] Tribal Water Issues Exemplified by the Navajo Nation

14 Dec 2022 | EHP

Mining-related contamination is one of the better-known problems in Navajo water, but other drinking water contaminants, such as PFAS, are understudied on Tribal lands and any regulations should consider Navajo principles and sovereignty.

Federal PFAS Testing and Tribal Public Water Systems

14 Dec 2022 | EHP

Assessing and managing environmental health risks must incorporate culturally significant practices and traditional ecological knowledge, as well as Tribally defined boundaries and traditional hunting and fishing areas in addition to adequate testing.

Cross-sectional associations of maternal PFAS exposure on SARS-CoV-2 IgG antibody levels during pregnancy

14 Dec 2022 | Environ Res

PFAS, including short-chain emerging PFAS, act as immunosuppressants during pregnancy.

Emerging Contaminants and New POPs (PFAS and HBCDD) in Endangered Southern Resident and Bigg’s (Transient) Killer Whales (Orcinus orca): In Utero Maternal Transfer and Pollution Management Implications

13 Dec 2022 | ACS

7:3-fluorotelomer carboxylic acid was the primary PFAS detected in killer whales' skeletal muscle and liver samples in the Northeastern Pacific Ocean, followed by PFOS, PFOA, and PFHxS.

12 Dec 2022 | Chemosphere

Maternal age, maternal education, diet, and nutritional supplementation during pregnancy can all affect umbilical serum exposure to PFAS.

Per- and polyfluoroalkyl substances (PFAS) exposure in melanoma patients: a retrospective study on prognosis and histological features

9 Dec 2022 | Environ Health

​​PFAS exposure based on geographical areas affected by PFAS contamination was associated with higher levels of cell replication in melanoma patients.

Human serum poly- and perfluoroalkyl substance concentrations and their associations with gestational diabetes mellitus

6 Dec 2022 | Environ Pollut

Higher serum PFAS concentrations were associated with gestational diabetes incidence in pregnant women, especially for PFOA, PFNA, PFHxS, and 6:2 Cl-PFESA.
