Per-and polyfluoroalkyl substances (PFAS) contamination in agriculture and its potential conflict with circular economy
8 Sep 2025 | Environmental Pollution
Efforts to promote a circular economy in agriculture, such as reusing biosolids and treated wastewater, risk reintroducing PFAS into soils and food chains, highlighting the need for stricter controls and safer alternatives.
A geospatial dataset of PFOS and PFOA occurrence records in China’s multi-media environments
8 Sep 2025 | Nature
PFOS and PFOA, were found widely across China’s water, soil, air, food, and living organisms between 2021 and 2024, with the new geospatial dataset revealing pollution hotspots and recent declines in human blood levels linked to stricter regulations.
Exploring the distribution of per-and polyfluoroalkyl substances (PFAS) in surface water and wildlife from the Galápagos Islands
8 Sep 2025 | Reg. Stud. Mar. Sci.
PFAS were found to reach the Galápagos Islands, contaminating surface waters and building up in wildlife such as marine iguanas, fish, and especially sea lions, posing risks to the health of this fragile ecosystem.
Reliable and sensitive ultra-short chain per- and polyfluorinated alkyl substances (PFAS) analysis in food: a polar reverse-phase chromatography approach
2 Sep 2025 | J Chromatogr A
A new chromatography method was developed to detect ultra-short-chain PFAS in tomato products, revealing their presence in common foods and offering a reliable tool for improved food safety monitoring.
Prenatal exposure to a mixture of per- and polyfluoroalkyl substances (PFAS) and lung function and immune-related outcomes among males in childhood and young adulthood
2 Sep 2025 | Environ Res
Prenatal exposure to mixtures of PFAS was linked to reduced lung capacity in young adult males and a lower chance of hay fever in childhood, but showed no clear connection with asthma or eczema.
Detection and Quantitation of Per- and Polyfluoroalkyl Substances in North Carolina Sea Foam and the Corresponding Sea Water
27 Aug 2025 | Environ Sci Technol
Sea foam along the North Carolina coast contains extremely high levels of PFAS, sometimes millions of times above drinking water limits, making it a major reservoir of these harmful chemicals and a potential risk to people and ecosystems.
Co-occurrence behaviors of per- and polyfluoroalkyl substances (PFASs) and heavy metals in the groundwater of dyeing industrial sites in southern China
27 Aug 2025 | Ecotoxicol Environ Saf
Groundwater beneath long-operating dyeing industrial sites in southern China is heavily contaminated with both PFAS and toxic heavy metals, with concentrations varying by season and site, highlighting serious risks to water safety and the need for integrated pollution control.
Association between perfluoroalkyl and polyfluoroalkyl substances exposure and hypercholesterolemia among US adults: A cross-sectional study
25 Aug 2025 | Ecotoxicol Environ Saf.
Analysis of NHANES 2015–2018 data (n = 2,292) showed that higher serum levels of PFHxS, PFOA, and PFOS were significantly associated with increased prevalence of hypercholesterolemia, with PFHxS as the strongest contributor in mixture models, while combined PFAS exposure consistently elevated risk across multiple statistical approaches.
Recent advances in the detection of per-and polyfluoroalkyl substances (PFAS) in food: A review of optical sensors, electrochemical sensors, and biosensor
25 Aug 2025 | Trends in Food Science & Technology
Nanomaterial-based optical sensors, electrochemical techniques such as voltammetry and impedance spectroscopy, and biosensors were found to be able to detect PFAS in food at trace levels from parts per million down to parts per trillion, allowing faster, portable, and more selective alternatives to chromatography and mass spectrometry.
Integrating ultrashort-chain compounds into the comprehensive analysis of per- and polyfluorinated substances in ready-to-feed liquid milk samples
25 Aug 2025 | Journal of Chromatography Open
Across the 24 American milk samples tested, PFAS were found in every type, including dairy, plant-based, and infant formula, with ultrashort-chain compounds like trifluoroacetic acid, trifluoromethanesulfonic acid, and short-chain PFAS such as PFBA and PFHpA being the most widespread.
The landscape of PFAS contamination in the United States: sources and spatial patterns
24 Aug 2025 | Environ. Sci. Technol.
PFAS contamination is widespread across the United States, with groundwater detections exceeding health limits at nearly all tested sites, especially around military bases, airports, and firefighting foam users, while industrial and waste facilities account for most likely sources and drive regional hotspots that raise major water safety and environmental justice concerns.
Mitigating PFAS contamination in the United States: Assessing the impact of California’s legislation from 2018 to 2022 on drinking water quality
23 Aug 2025 | JPHP
California’s 2018–2022 PFAS laws helped cut PFOA and PFOS levels in drinking water by more than half, showing that strong state policies can significantly reduce contamination and serve as a model for national action.
Associations between per- and polyfluoroalkyl substances and type 2 diabetes: The modifying effects of lifestyle and genetic risk
23 Aug 2025 | J Hazard Mater
Certain PFAS chemicals (like PFOA, PFNA, PFBA, and PFHpA) are linked to a higher risk of type 2 diabetes and these effects are made stronger by lifestyle choices and high genetic risk.
