摘　　要：基于已报道的中国城市污水处理厂二级处理出水中内分泌干扰物的浓度,分别在以出水最大浓度为背景的极端情景和以出水中位浓度为背景的一般情景下,计算和分析了工业化学品、农药、天然雌激素、药物4类共32种内分泌干扰物的生态风险商和雌二醇当量浓度.结果表明,在极端情景下,分别有12种和9种物质具有生态风险和内分泌干扰性;其中,分别有6种和5种物质在一般情景下也具有生态风险和内分泌干扰性.在此基础上,通过评分和排序得出在中国城市污水处理厂应当优先控制的4种污染物为炔雌醇、雌酮、壬基酚、双酚A.Ecological risk quotients and estradiol equivalent concentrations of 32 endocrine disrupting chemicals （EDCs） in 4 categories were calculated and analyzed using reported concentrations in secondary effluents from municipal wastewater treatment plants in China, considering both extreme scenario for maximum concentration and moderate scenario for median concentration. These EDCs include industrial chemicals, pesticides, natural estrogens, and pharmaceuticals. In extreme scenario, 12 chemicals of ecological risk and 9 chemicals of estrogenicity were identified. While in moderate scenario, 6 chemicals of ecological risk and 5 chemicals of estrogenicity were identified. After further scoring and ranking, 4 priority EDCs have been suggested for control in municipal wastewater treatment plants in China, including 17a-ethynylestradiol, estrone, nonylphenol, and bisphenol A.
