Endocrine disrupting compounds (EDCs), pharmaceuticals, and personal care products (PPCPs) have been of great concern as emerging contaminants of aquatic environments. In this study, the risks of EDCs and PPCPs in the Yangtze River Basin were ranked, based on their environmental exposure datasets and ecotoxicity datasets. The prioritized chemicals were then identified. The results found that EDCs and personal care products were deemed to represent higher risks to aquatic organisms, for example, estrone, estriol, 17-estradiol, bisphenol S, atrazine, triclocarban, and triclosan, while the risks of pharmaceuticals were 500-fold lower. Among the pharmaceuticals, antibiotics posed relatively higher risks. The Xiangjiang River and Honghu Lake with its surrounding rivers were hotspots where more chemicals were found with the highest concentrations, followed by Taihu Lake, Dongting Lake and the Yangtze River Delta. When comparing with algae and worms, fish were the most sensitive taxa to 17-estradiol and 17-ethynylestradiol. The results of this work provide sound guidance for the future monitoring and management of chemicals in China.
内分泌干扰化合物（EDCs）、药品和个人护理产品（PPCPs）作为水环境中的新兴污染物已备受关注。在本研究中，基于长江流域的环境暴露数据集和生态毒性数据集，对EDCs和PPCPs的风险进行了排序。随后确定了优先化学品。结果发现，EDCs和个人护理产品被认为对水生生物构成更高风险，例如雌酮、雌三醇、17-β-雌二醇、双酚S、阿特拉津、三氯卡班和三氯生，而药品的风险则低500倍。在药品中，抗生素构成的风险相对较高。湘江及其周边河流以及洪湖是发现更多化学品且浓度最高的热点地区，其次是太湖、洞庭湖和长江三角洲。与藻类和蠕虫相比，鱼类是对17-β-雌二醇和17-乙炔基雌二醇最敏感的分类群。这项工作的结果为中国未来化学品的监测和管理提供了可靠指导。
