Abstract

This study analyzed the characteristics of 18 endocrine disrupting compounds (EDCs) detected in four wastewater treatment plants in Nanjing, China. The removal efficiency, ecological and health risks of EDCs were evaluated. The results showed that EDCs were detected to different degrees, with prednisone as the main contributor, and the total concentrations of EDCs ranged from 532.89 to 8535.88 ng/L and 14.98 to 128.91 ng/L, respectively. Most of the EDCs were significantly decreased after secondary treatment, with removal efficiencies ranging from 9.7% to 100%. The ecological risk assessment showed that trenbolone and norethindrone had the highest risk quotients and posed a high risk to aquatic organisms. The health risk evaluation suggested that the health risk values in the cases of adult drinking water route, children's drinking water route, and adult exposure route were all less than 1, indicating that EDCs did not pose significant non-carcinogenic health hazards to humans.

南京市污水处理厂18种内分泌干扰物的发生、去除及生态与人体健康风险评价

本研究分析了中国南京市4个污水处理厂中检测到的18种内分泌干扰化合物（EDCs）的特征。对EDCs的去除效果、生态风险和健康风险进行了评价。结果表明，EDCs的检出程度不同，以强的松为主，EDCs的总浓度范围分别为532.89 ~ 8535.88 ng/L和14.98 ~ 128.91 ng/L。经二次处理后，大多数EDCs的去除率显著降低，去除率在9.7% ~ 100%之间。生态风险评价结果显示，trenbolone和norethindrone的风险系数最高，对水生生物构成较高的风险。健康风险评价结果显示，成人饮水途径、儿童饮水途径和成人暴露途径的健康风险值均小于1，表明EDCs对人类不构成显著的非致癌性健康危害。
