Identifying Populations with Elevated PFAS Exposure by Targeted Serum Sample Pooling
Science
20 May 2025 | Expo Health
By pooling leftover and de-identified blood samples from people who live near suspected contamination sites, Australian researchers were able to detect elevated levels of PFAS in two communities, showing that this quick biomonitoring method can serve as an early warning system for further investigation and public-health action.

National Assessment of PFAS in Landfill Leachate in China: Non-Negligible Ultrashort-Chain Components and Socioeconomic Impacts
Science
20 May 2025 | Environ Sci Technol
A nationwide survey of 70 Chinese landfills found that their wastewater holds sizable amounts of PFAS, mostly newer ultrashort‑chain chemicals, releasing about 419 kg into the environment each year and underscoring the need for stricter waste controls.

A comprehensive analytical approach to monitoring selected emerging contaminant classes in sewage sludge and e-waste from Norway
Science
19 May 2025 | J. Environ. Chem. Ecotoxicol.
Norwegian researchers found that anaerobic digestion of sewage sludge converts PFAS precursors into highly mobile perfluorocarboxylic acids and leaves more persistent long‑chain PFAS, while discarded e‑waste plastics, although less contaminated, still harbor up to 176 ng g⁻¹ of PFAS, indicating that both sludge treatment and electronics recycling inadvertently leak these pollutants.

Skin sampling as a proxy for screening per- and polyfluoroalkyl substances (PFAS) exposures in endangered sea turtles
Science
19 May 2025 | Mar Pollut Bull
Small skin samples collected from stranded green sea turtles in Texas showed PFAS levels, especially PFOS, that closely matched those in the turtles’ blood, demonstrating that quick, minimally invasive skin biopsies can reliably track exposure to these persistent pollutants in endangered populations.

Identification and environmental occurrence of novel per- and polyfluoroalkyl substances derived from lithium-ion battery
Science
18 May 2025 | Water Res
Water and sediment near lithium‑ion battery factories and recycling sites in China contain 33 different PFAS chemicals, including seven never documented before, revealing that battery production and recycling can release highly mobile short‑chain PFAS that may endanger ecosystems and human health.

Uncovering the effects of the North Pacific Subtropical Gyre on per-and polyfluoroalkyl substances distribution in the Tropical Western Pacific
Science
14 May 2025
Scientists warn that the North Pacific’s huge swirling gyre is now amassing large amounts of short‑chain “forever chemicals” such as PFBA—along with residual PFOA—making these substitutes the main pollutants in Tropical Western Pacific surface waters and raising new worries for ocean life and human health.

Exposure to Legacy Per- and Polyfluoroalkyl Substances from Diet and Drinking Water in California Adults, 2018-2020
Science
14 May 2025 | Environ Sci Technol
This study characterized legacy PFAS in serum from 700 California adults and examined contributions from diet and drinking water concluding that drinking water remains an important source of exposure to PFOA and PFHxS in this population.

Hair analysis as a non-invasive method for assessing the exposure of wildlife to per- and poly-fluoroalkyl substances (PFAS)
Science
13 May 2025 | Environ Pollut
By analyzing blood samples from 700 adults in southern and eastern California, scientists found that even low but detectable PFAS in local tap water significantly raised people’s levels of the legacy chemicals PFOA and PFHxS, while seafood and eggs contributed smaller amounts.
