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

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

Science
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.

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
Science
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.
