Global Inland and Freshwater PFAS Concentrations Dataset: A Compilation of Legacy and Emerging Per- and Polyfluoroalkyl Substances in Rivers, Lakes, and Polar Freshwaters (2006–2023)

This dataset provides a curated, synthesized global compilation of per- and polyfluoroalkyl substances (PFAS) concentrations measured across various inland water matrices—including rivers, lakes, surface runoff, and polar freshwater/snow matrices—over a 17-year timeline from 2006 to 2023. Consisting of 376 distinct rows extracted from 30 unique scientific references, this asset supports hydrological modeling, environmental monitoring, ecological risk assessment, and tracking the transition from legacy chemicals to modern alternatives in freshwater systems.
