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.
