Ten years of PFOS and PFOA human biomonitoring in Italy: Exposure levels and determinants of exposure
Science
14 Mar 2025 | Chemosphere
PFAS exposure in the Italian population has declined over ten years for PFOA but not for PFOS, with higher levels observed in men, individuals in urbanized areas, and those with higher education or occupational skill levels, while proximity to PFAS-emitting industries remains the strongest predictor of elevated exposure.

Storm Daniel extreme flood event in Thessaly, Greece: Assessing the pollution status of the impacted coastal marine areas through extended screening of emerging contaminants using LC-TIMS-HRMS
Science
4 Mar 2025 | Environ. Sci. Technol. Lett.
Storm Daniel’s extreme flooding in Thessaly, Greece, led to a significant increase in PFAS contamination in coastal waters and sediments, with legacy PFAS like PFOS and emerging compounds such as ADONA detected at elevated levels, primarily due to wastewater overflow and industrial facility damage.

Holistic assessment of chemical and biological pollutants in a mediterranean wastewater effluent-dominated stream: Interactions and ecological impacts
Science
12 Feb 2025 | Environ. Pollut.
PFAS were detected in wastewater effluent on the Onyar River, in the northeast Spain, with PFOS showing the highest PFAS concentrations. PFPeA was the only PFAS detected downstream but not upstream, suggesting that its primary source was wastewater.

Per‐and polyfluoroalkyl substances in untreated and treated sludge/biosolids from 27 water resource recovery facilities across the United States and Canada
Science
9 Feb 2025 | Water Environ Res.
PFAS were detected in untreated and treated sludge biosolids from 27 water resource recovery facilities across the U.S. and Canada, with post-stabilized biosolids generally showing higher concentrations than pre-stabilized sludge, particularly for 5:3 FTCA and PFOS.

PFAS concentrations in the blood of Danish surfers
Science
20 Jan 2025 | Int J Hyg Environ Health
PFAS concentrations in the blood of Danish surfers were measured, revealing no significant relationship between the amount of time spent surfing and higher PFAS levels, but male sex and eating meat from free-ranging animals were found to be potential risk factors for increased exposure.

[Press Release] Attorney General Bonta Co-leads Amicus Brief Defending Nationwide PFAS “Forever Chemicals” Drinking Water Standards
Policy
17 Jan 2025
California Attorney General Rob Bonta today co-led a coalition of 17 states in filing an amicus brief in the U.S. Court of Appeals for the D.C. Circuit defending a U.S. EPA rule establishing the first nationwide drinking water standards for certain toxic PFAS, also known as “forever chemicals,” under the Safe Drinking Water Act.

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
Science
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.
