Enhanced immobilisation of per-and polyfluoroalkyl substances (PFAS) using a combination of sorbents and plants: A controlled rainfall simulation study
Science
23 Jun 2025 | Sci. Total Environ.
Lab tests show that mixing PFAS-tainted soil with powdered activated carbon and planting hardy ryegrass on top prevented about 90% of the PFAS from being washed away by heavy rain, pointing to a simple, inexpensive way to keep PFAS out of nearby waterways.

Assessing contamination and risk profiles of per-and polyfluoroalkyl substances across various types of water in South Africa: trends over the past decade (2014–2024)
Science
23 Jun 2025 | Emerging Contaminants
Across South Africa, surface waters and wastewater often contain PFOA and other PFAS at levels as high as 420 ng/L, creating serious ecological risks even though indirect human exposure through irrigated crops is currently minimal, underscoring the need for tougher regulation and better water treatment.

Heavier sediment pollution by per-and polyfluoroalkyl substances (PFASs) in tropical coasts compared to temperate regions: An overlooked hotspot
Science
14 Jun 2025 | J. Environ. Sci.
Sediments along a tropical Chinese coastline contain markedly higher levels of both legacy and emerging PFAS, reaching about 13 ng/g dry weight and dominated by mid-chain compounds such as PFHxA and 9H-PFNA, a concentration exceeding those typically reported for temperate regions; researchers trace the pollution to land-based runoff, rocket-launch fallout, and other local sources.

Long term trends of legacy per-and polyfluoroalkyl substances (PFAS), their substitutes and precursors in archived wildlife samples from the German Environmental Specimen Bank
Science
9 Jun 2025 | Environ Int.
Decades of German wildlife records show that although banned C8 PFAS like PFOS have decreased, they are still persistent in gull eggs and fish livers, while longer-chain PFAS and newer short- and ultrashort-chain substitute levels are now increasing.
