摘　　要：为了对三峡库区重点饮用水源地的水质状况进行全面评价,对三峡库区9个重点饮用水源地实测样本进行了常规水质参数、微量有机物和藻毒素含量分析。评价结果表明:三峡库区重点饮用水源地水质状况良好,水源地水质类别为Ⅱ～Ⅲ类,满足集中式供水水源地水质要求;实际检测未发现多氯联苯、有机磷农药和多环芳烃等微量有机物,仅有2个水源地检测出微量有机氯农药,但均在限定值以下;藻类毒素也未检出。调查的水源地水质安全综合指数为1～2级,达到水源地水质安全指数要求。In order to comprehensively evaluate the water quality of drinking water source area in the Three Gorges Reservoir area, the conventional water quality parameters, trace organics and algal toxins of samples taken in 9 important drinking water source areas are analyzed and evaluated. The results show that the water quality condition is good; water classification belongs to Ⅱ～Ⅲ, meeting the water quality requirement for centralized drinking water sources; trace organics of polychlorinated biphenyl, organic phosphorus pesticide and polycyclic aromatic hydrocarbons are not found in the practical check, organic chlorine pesticide is found only in 2 drinking water source areas and is under the limitation value; algal toxins is also not found. The water quality safety indexes in the drinking water source area range from 1 to 2, meeting the requirement of safe drinking water source area.
