Unveiling per-and polyfluoroalkyl substances contamination in e-cigarette refill liquids: A comprehensive analytical assessment
15 Jan 2025 | Sci. Total Environ.
PFAS contamination was found in 84% of e-cigarette refill liquids, with certain compounds detected at significant levels, raising concerns about additional health risks from vaping and PFAS environmental release.
Common infections in children aged 6 months to 7 years after high prenatal exposure to perfluoroalkyl substances from contaminated drinking water in Ronneby, Sweden
7 Jan 2025 | Environ Res
High prenatal exposure to PFAS from contaminated drinking water in Sweden was linked to an increased risk of childhood ear infections and potentially eye and urinary tract infections.
Sex specificity in associations between exposure to a mixture of per and poly-fluoroalkyl substances and anxiety among US adults
7 Jan 2025 | J Expo Sci Environ Epidemiol
Exposure to mixtures of PFAS was linked to anxiety in U.S. adults, with males showing decreased anxiety and females showing increased anxiety, highlighting sex-specific effects.
Evaluating Dermal Absorption of Perfluorooctanoic Acid (PFOA) and Implications for Other Per-and Polyfluoroalkyl Substances (PFAS)
6 Jan 2025 | Regul Toxicol Pharmacol
PFOA was found to have low dermal absorption compared to other harmful chemicals, with these authors selecting a 1.6% absorption rate as the published value most likely to be accurate, suggesting that ingestion remains a higher exposure pathway compared to skin contact.
Unveiling the Truth of Interactions between Microplastics and Per-and Polyfluoroalkyl Substances (PFASs) in Wastewater Treatment Plants: Microplastics as a Carrier of PFASs and Beyond
6 Jan 2025 | Environ. Sci. Technol.
Microplastics in wastewater treatment plants were found to carry PFAS at concentrations ranging from 122 to 166 ng/g, with dominant compounds like PFOS and PFOA showing strong sorption and desorption behaviors, highlighting the dual roles of microplastics as both carriers and sources of PFAS.
High organofluorine concentrations in municipal wastewater affect downstream drinking water supplies for millions of Americans
6 Jan 2025 | Proc Natl Acad Sci U S A
Municipal wastewater treatment plants were found to discharge high concentrations of organofluorine compounds, including fluorinated pharmaceuticals and PFAS, with limited removal efficiency (<25%), significantly contaminating downstream drinking water supplies for up to 23 million Americans.
Per- and polyfluoroalkylated substances (PFAS) in the feathers and excreta of Gentoo penguins (Pygoscelis papua) from the Antarctic Peninsula
30 Dec 2024 | Sci Total Environ
Gentoo penguins exhibit bioaccumulation of PFAS compounds in feathers and excreta (including the first report of NaDONA in Antarctica), with adults showing higher levels than chicks; this study highlights the global reach of anthropogenic pollutants and the need for further investigation into their ecological impact.
Cleaner cuts: Farmed fish and skin-off fillets are lower in per- and polyfluoroalkyl substances (PFAS)
28 Dec 2024 | Sci Total Environ
Farmed fish and skin-off fillets generally contain lower levels of harmful PFAS chemicals compared to wild fish and skin-on fillets, making them potentially safer dietary choices for reducing exposure to these persistent environmental pollutants.
Target and non-target screening of poly-and perfluoroalkyl substances (PFAS) in fish liver samples from the River Nile in Sudan: A baseline assessment
24 Dec 2024 | Mar. Pollut. Bull.
PFAS contamination in fish livers from the Nile River, particularly downstream of a Sudanese Dam, is significant, with some levels exceeding international safety standards, emphasizing the need for continued monitoring and research into environmental and food safety risks in the region.
Characterization of PFAS Residuals: A Case Study on PFAS Content in a Firefighting Foam Delivery System of an Aircraft Rescue and Firefighting Vehicle
24 Dec 2024 | Chemosphere
Residual PFAS contamination in firefighting foam systems, even after rinsing, highlights the need for targeted replacement of critical components as brass and rubber parts retain the highest contamination levels.
Predicted Potential for Aquatic Exposure Effects of Per-and Polyfluorinated Alkyl Substances (PFAS) in Pennsylvania’s Statewide Network of Streams
19 Dec 2024 | Toxics
A machine learning model was used to effectively predict the ecological health risks of PFAS in Pennsylvania stream water, finding that industrial/urban land cover, rainfall intensity, geology, and agricultural factors had the greatest impacts.
Per-And Poly-Fluoroalkyl Substances (PFAS) Exposure and Risk of Breast, and Female Genital Cancers: A Systematic Review and Meta-Analysis
19 Dec 2024 | Med Lav.
Exposure to PFAS may be associated with an increased risk of ovarian cancer and a potential link to breast cancer, though further research is needed to clarify these relationships.
Presence of Perfluorohexanoic Acid in Fluoroelastomer Watch Bands
18 Dec 2024 | Environ. Sci. Technol. Lett.
The detection of high PFHxA concentrations in fluoroelastomer watch bands raises significant concerns about dermal exposure and potential health impacts, emphasizing the need for further studies on its absorption and toxicity.
Late lessons from early warnings on PFAS
17 Dec 2024 | Nature Water
Recent PFAS regulations in the U.S. and Europe highlight the need for significant investment by water providers, innovation to avoid harmful replacements, and reforms to regulatory approaches that have historically focused on case-by-case assessments anddelayed action despite early warnings of PFAS persistence, bioaccumulation, and toxicity.
