对徐州市3家不同处理工艺污水厂进出水中的17α-乙炔基雌二醇（EE2）、雌三醇（E3）、雌二醇（E2）、雌酮（E1）、双酚 A（BPA）等5种雌激素物质进行了分析，采用固相萃取技术对这些物质进行富集分离，使用 LC -MS 对目标物进行检测。结果表明，3座污水厂的雌激素（除 BPA）平均进出水浓度较高，污水厂对 EE2和 BPA 的去除效果较好，分别为84．89％和98．38％；但对 E3、E2、E1去除效果不够理想。经对内分泌干扰物的雌激素活性及生态风险进行评价，建议徐州地区应优先控制 EE2、E1和 E3。%Five kinds of estrogens including 17α-ethynylestradiol (EE2),17β-estradiol (E2),estriol (E3),estron (E1)and bis-phenol Ainthe water samples collected fromthree wastewater treatment plants located inXuzhou,Jiangsu Province were monitored. They were concentratedand separated by the method of solid phase extraction and determined with LC-MS.Result shows that the av-erage concentrations of the estrogens (except BPA)in the effluent arehigh.The removal rates of EE2 and BPA arehigh and they are 84.89% and 98.38%,respectively.However,the removal rates of the other estrogens arerelatively low.It is also suggested that EE2,E1,E3 should be preferentially controlled in Xuzhou by assessingthe EEQ and RQ of each estrogen.
