EU floats plan that would ban virtually every PFAS currently on the market
News
9 Feb 2023 | Chemistry World
The five countries want to essentially ban the entire class of more than 10,000 chemicals in a single stroke, including their production, use, and sale, and the impact would be significant.

Systematic review and meta-analysis of epidemiologic data on vaccine response in relation to exposure to five principal perfluoroalkyl substances
Science
7 Feb 2023 | Environ Int
Serum PFAS concentrations may reduce antibody response after vaccination, especially for diphtheria, rubella, and tetanus.

Transport and transformation of perfluoroalkyl acids, isomer profiles, novel alternatives and unknown precursors from factories to dinner plates in China: New insights into crop bioaccumulation prediction and risk assessment
Science
4 Feb 2023 | Environ Int
Extremely high PFAS levels were measured in agricultural fields and vegetables near fluorochemical manufacturing facilities, and some precursor degradation and volatilization loss of PFAS was found during vegetable cooking.

Historical Trend of Exposure to Perfluoroalkyl Surfactants PFOA, ADV, and cC6O4 and its Management in Two Perfluoroalkyl Polymers Plants, Italy
Science
28 Jan 2023 | Ann Work Expo Health
PFAS blood contamination was reduced 5- to 136-fold in fluoropolymer industry workers after several initiatives to reduce exposure.

Pennsylvania to limit PFAS in drinking water
Policy
14 Jan 2023
The new rule sets maximum contaminant levels in drinking water for two forms PFAS – in order to protect the public from potential adverse health effects linked to exposure to PFOA and PFOS.

Occurrence and implications of per and polyfluoroalkyl substances in animal feeds used in laboratory toxicity testing
Science
10 Jan 2023 | Sci Total Environ
PFAS contamination in animal feed was found to be pervasive, which is significant because unintended PFAS exposure in control animals from feed can significantly bias toxicity testing.

Emerging and legacy contaminants in common minke whale from the Barents sea
Science
4 Jan 2023 | Environ Pollut
PFAS levels were higher in fetuses than male or female adult whales, and PFOS levels were higher than those detected from the same population eight years previously.

Contact to perfluoroalkyl substances and thyroid health effects: A meta-analysis directing on pregnancy
Science
4 Jan 2023 | Chemosphere
A systematic review found that PFOS, PFOA, and PFDA exposures were associated with thyroid disruption in pregnant women, who were more sensitive to PFAS exposure in the first six months of pregnancy.

Early-life exposure to per- and polyfluoroalkyl substances and infant gut microbial composition
Science
3 Jan 2023 | Environ. Epi.
PFAS may increase infant gut microbiome diversity, which has been associated with an increased risk of infection.

Per- and polyfluoroalkyl substances (PFAS) in breast milk and infant formula: A global issue
Science
3 Jan 2023 | Environ. Res.
Breast milk concentrations of PFOA and PFOS often exceed children’s drinking water screening values, and limited information on infant formula means that families cannot generally know whether their infant’s exposures exceed safe levels.

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.
-
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.

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