Per- and polyfluoroalkyl substances and global water resources: an in-depth review of existing regulatory frameworks worldwide
5 Feb 2025 | Int. J. Environ. Sci. Technol.
Global efforts to regulate PFAS are hindered by inconsistent policies, political and economic barriers, and scientific uncertainties, despite increasing evidence of their persistence, bioaccumulation, and toxicity in water resources; the study emphasizes the need for stronger international collaboration and enforcement to effectively manage PFAS pollution.
Per- and Poly-fluoroalkyl Substances (PFAS) in Sediment: a Source of PFAS to the Food Web?
4 Feb 2025 | Integr Environ Assess Manag
While treatment of wastewater treatment plant effluent initially decreased PFAS levels in Kent Lake fish in Michigan, high contamination levels were found to continue due to PFAS accumulation in sediment acting as a persistent contamination source.
Emerging PFAS Exposure Is More Potent in Altering Childhood Lipid Levels Mediated by Mitochondrial DNA Copy Number
3 Feb 2025 | Environ Sci Technol
Exposure to emerging PFAS, such as 6:2 Cl-PFESA, PFO4DA, and PFO5DoDA, is linked to higher triglycerides, total cholesterol, and low-density lipoproteins in Chinese children aged 7–10 years, suggesting an increased risk of metabolic disorders, including obesity, cardiovascular diseases, and diabetes.
Per- and Poly-Fluoroalkyl Substances, and Organophosphate Flame Retardants in the Upper Yangtze River: Occurrence, Spatiotemporal Distribution, and Risk Assessment
1 Feb 2025 | Toxics
PFAS and OPFRs were detected in the upper Yangtze River, with higher concentrations in the main stream than in tributaries, particularly near industrial and urban areas, and while ecological risks were generally low, some locations, especially near wastewater discharge sites, showed potential carcinogenic risks for adults due to OPFR exposure.
PFAS exposure during pregnancy: Implications for placental health and functioning
30 Jan 2025 | Environ. Int.
Exposure to PFAS during pregnancy has been linked to impaired placental health, including reduced placental weight, altered fetal-maternal exchange, and disrupted vascularization, which may contribute to pregnancy complications such as fetal growth restriction and preeclampsia.
Per- and Polyfluoroalkyl Substances and Twin Growth Discordance: New Insights from a Twin Birth Cohort Study
29 Jan 2025 | Environ Sci Technol
Prenatal exposure to PFAS is associated with greater differences in birth weight and height between twin siblings, with non-identical twins being more affected than identical twins.
Emerging Per- and Polyfluoroalkyl Substances in Tap Water from the American Healthy Homes Survey II
29 Jan 2025 | Environ Sci Technol
Non-targeted analysis of American tap water samples revealed widespread contamination with emerging PFAS, many of which are not detected by standard monitoring methods, highlighting the need for broader PFAS screening to assess human exposure risks.
Anti-icing properties of polar bear fur
29 Jan 2025 | Sci Adv
Polar bear fur naturally prevents ice buildup due to its sebum composition, reducing ice adhesion similarly to fluorocarbon coatings, and providing insights for developing environmentally friendly anti-icing materials.
The Critical Role of Commercial Analytical Reference Standards in the Control of Chemical Risks: The Case of PFAS and Ways Forward
29 Jan 2025 | Environ Health Perspect
Through a PFAS case study, the authors argue that the limited availability of reference standards undermines the ability of scientists to produce independent scientific evidence needed for chemical risk governance and, thereby, prevents society from protecting people and the environment against chemical pollution.
Prenatal Per- and Polyfluoroalkyl Substances in Relation to Antibody Titers and Infections in Childhood.
28 Jan 2025 | Environ Res
Higher prenatal exposure to PFAS is linked to weaker immune responses in children, leading to lower vaccine antibody levels and increased risk of infections, particularly respiratory illnesses, during early childhood.
Water industry strategies to manufacture doubt and deflect blame for sewage pollution in England
27 Jan 2025 | Nature Water
Water and sewerage companies in England were found to use 22 greenwashing, disinformation, and manufacturing doubt tactics to help diminish their contributions to water pollution.
Exploring the Chemical Complexity and Sources of Airborne Fine Particulate Matter in East Asia by Nontarget Analysis and Multivariate Modeling
27 Jan 2025 | Environ Sci Technol
Airborne fine particulate matter (PM2.5) in East Asia contains thousands of complex organic and inorganic chemicals, including newly identified PFAS seasonal variations are influenced by temperature and air mass origins from China, the Korean Peninsula, and surrounding seas.
