Аннотация
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: Bisphenols and per- and polyfluoroalkyl substances (PFASs) are endocrine-disrupting chemicals found in aquatic ecosystems. Henan, a critical water conveyance region within the South-to-North Water Diversion Project, encompasses four river basins characterized by complex hydrological conditions. However, systematic monitoring of contaminant levels remains insufficient.
WHAT IS ADDED BY THIS REPORT?: This study identified key priority pollutants and highlighted the dominance of short-chain PFASs in the region.
WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: These baseline data address gaps in existing knowledge on emerging pollutants omitted from GB 5749-2022, thereby providing critical scientific evidence to guide the revision of national drinking water standards, strengthen watershed pollution control, and safeguard public health and ecotoxicological integrity.
