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
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.
Association of per-and polyfluoroalkyl substance exposure with fatty liver disease risk in US adults
2 Feb 2023 | JHEP Rep.
Higher serum PFAS was moderately associated with decreased liver function in the general population, especially in those with independent risk factors such as heavy alcohol intake, obesity, or high-fat diets.
Penetration of Perfluorooctanesulfonate Isomers and Their Alternatives from Maternal Blood to Milk and Its Associations with Chemical Properties and Milk Primary Components
2 Feb 2023 | Environ Sci Technol
PFOS and Cl-PFESAs were found to move between cells, transferring from blood to human milk.
Per-and Polyfluoroalkyl Substances (PFAS) Distribution in Landfill Gas Collection Systems: Leachate and Gas Condensate Partitioning
31 Jan 2023 | J. Haz. Mat.
PFAS identities and concentrations were compared in landfill gas condensate and leachate within gas wells, including more semi-volatile PFAS rarely measured in water matrices.
Occupational exposures to airborne per- and polyfluoroalkyl substances (PFAS)-A review
31 Jan 2023 | Am J Ind Med
Ski waxing exhibited the highest total PFAS airborne concentrations when compared to other reported occupational and residential exposures, and the authors suggest that safety measures should be developed to protect workers from the adverse health effects of PFAS.
Red blood cell folate modifies the association between serum per- and polyfluoroalkyl substances and antibody concentrations in U.S. adolescents
30 Jan 2023 | Environ. Sci. Technol.
Associations between higher serum PFAS and lower disease antibodies were found to be significant only in adolescent groups with lower folate levels, suggesting that folate may be used as a mitigation measure against immune-related PFAS effects.
Historical Trend of Exposure to Perfluoroalkyl Surfactants PFOA, ADV, and cC6O4 and its Management in Two Perfluoroalkyl Polymers Plants, Italy
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.
Levels and distribution profiles of Per- and Polyfluoroalkyl Substances (PFAS) in a high Arctic Svalbard ice core
27 Jan 2023 | Sci Total Environ
Analysis of C2-C11 PFCAs in an arctic ice core found that TFA represented 71 % of the total mass of PFCAs and exhibited an increasing atmospheric deposition trend over time.
Geographic and demographic variability in serum PFAS concentrations for pregnant women in the United States
25 Jan 2023 | J Expo Sci Environ Epidemiol
Mapping showed that participants’ proximity to local point sources can overshadow expected trends with demographic information, and environmental justice considerations were discussed.
Systematic review and meta-analysis of birthweight and PFNA exposures
24 Jan 2023 | Environ Res
Data analysis techniques allowing for more studies to be included in this review resulted in a stronger connection between birthweight deficits and PFNA exposure compared to previous PFAS meta-analyses.
Leaching of Perfluoroalkyl Acids during Unsaturated Zone Flushing at a Field Site Impacted with Aqueous Film Forming Foam
23 Jan 2023 | Environ Sci Technol
Remedial approaches that remove only a modest fraction of the PFAA mass in soil may be protective of underlying groundwater, particularly for some perfluorinated sulfonates.
Bioaccessibility of per- and polyfluoroalkyl substances in food and dust: Implication for more accurate risk assessment
20 Jan 2023 | Sci Total Environ
The bioaccessibility of PFAS was higher in simulated animal foods than in simulated vegetable foods, and the bioaccessibility of most very long-chain PFAS was higher in food than in dust.
Optimizing Chemicals Management in the United States and Canada through the Essential-Use Approach
19 Jan 2023 | Environ Sci Technol
If optimized and expanded into regulatory systems in the United States and Canada, other policymaking bodies, and businesses, the essential-use approach can improve chemicals management and shift the market toward safer chemistries that benefit human and ecological health.
The role of PFAS in unsettling ocean carbon sequestration
18 Jan 2023 | Environ Monit Assess
The harmful effects of PFAS on marine ecosystems may weaken the ocean’s ability to capture and hold global warming carbon emissions.
Evaluation of per- and polyfluoroalkyl substances (PFAS) in leachate, gas condensate, stormwater and groundwater at landfills
17 Jan 2023 | Chemosphere
To prioritize and improve PFAS remediation from discarded consumer products, relationships were found between PFAS and landfill characteristics, including aqueous samples like leachate and stormwater.
