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本数据集提供一套全面整合的全球汇编数据，收录了2002年至2023年这21年间海洋及远洋水体中测得的全氟和多氟烷基物质（per- and polyfluoroalkyl substances, PFAS）浓度。本数据集整合了全球76个独特采样点位的664组观测数据，将所涉及的化学化合物划分为传统型与新型两类。本数据集可为环境化学家、海洋科学家、海洋学家以及环境政策制定者提供高精度参考资源，助力其追踪海洋生态系统中持久性有机污染物（persistent organic pollutants, POPs）的全球分布、海洋运移屏障及长期变化趋势。
