Distribution pattern, source apportionment and health risk assessment of per and polyfluoroalkyl substances in drinking water treatment plants in South Africa
Science
26 May 2025 | Environ Toxicol Chem
Testing of drinking‑water plants in five South African provinces revealed measurable PFAS, sometimes climbing to hundreds of nanograms per litre, with one Northern Cape facility exceeding safety thresholds.

Per- and polyfluoroalkyl substances (PFAS) profiles in primary and secondary landfill leachates: Indications of transformation, liner interactions, and other PFAS sources
Science
24 May 2025 | J Hazard Mater
Tests at three modern, double‑lined Florida landfills showed that the supposedly isolated liquid beneath the main liner still contained thousands to tens of thousands of nanograms‑per‑litre of assorted PFAS, often rivaling or exceeding levels in the primary leachate, revealing that “forever chemicals” can slip through liners, transform, and build up despite today’s best landfill safeguards.

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.

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.

Atmospheric emission of per-and polyfluoroalkyl substances (PFAS) from a fluoropolymer manufacturing facility: Focus on emerging PFAS and the potential contribution of condensable PFAS on their atmospheric partitioning
Science
12 May 2025 | Environ. Sci. Technol.
A major fluoropolymer manufacturing facility in China was found to emit dozens of previously undetected PFAS—including emerging compounds like Cl-PFECAs and multi-head PFESs—into the air and surrounding environment, raising concern about widespread contamination and the need for stronger oversight of industrial PFAS emissions.

Distribution of perfluorooctanoic acid in exposed female postpubertal pigs in thermal neutral or heat-stressed conditions
Science
1 May 2025 | Toxicol Sci
Researchers found that heat stress increased the amount of PFOA absorbed and distributed in the bodies of female pigs, especially into their follicular fluid, suggesting that hot environments may worsen reproductive risks from chemical exposure.
