Global Marine PFAS Concentrations Dataset: A Compilation of Legacy and Emerging Per- and Polyfluoroalkyl Substances in Oceanic Waters (2002–2023)

This dataset provides a comprehensive, synthesized global compilation of per- and polyfluoroalkyl substances (PFAS) concentrations measured in marine and oceanic waters over a 21-year period spanning from 2002 to 2023. The dataset aggregates 664 observations across 76 unique sampling locations globally, categorizing chemical compounds into legacy and emerging classifications. It serves as a high-fidelity resource for environmental chemists, marine scientists, oceanographers, and environmental policymakers tracking the global distribution, marine transport barriers, and long-term trends of persistent organic pollutants (POPs) in marine ecosystems
