黄河水源地“三致”物监测必要性与断面布设探讨

The Necessity of Monitoring Carcinogen and Substances Which Cause Mutation and Malformation in Water Sources and the Study of the Layout of Monitoring Sections

在河流污染物中，致癌物、致突变物、致畸形物（简称“三致”物）毒性最强，对人体健康威胁最大。据检测，在黄河干流兰州段、包头段和郑州段等河段已存在一定程度的“三致”物污染，应尽早开展饮用水水源地“三致”毒物污染监测。根据沿黄城市的分布情况及河段污染特点，可在兰州市包兰桥断面、包头市镫口断面、郑州市花园口断面及河口段利津断面首先开展监测工作。

Among river polluttions, carcinogen and substances which cause mutation and malformation are most poisonous and most harmful to human health. From tesing, a certain degree of pollution has been caused by those substances in Lanzhou, Baotou and Zhengzhou segments of the Yellow RiverIS master stem. Thus, monitoring drinking water pollution caused by those substances must be conducted as soon as possible. According to the distribution of cities and the pollution characteristics of river segments, it is suggested to conduct monitoring at first at Lanzhou Bridge near Lanzhou city, Dengkou section near Baotou city, Huayuankou section near Zhengzhou city, and Lijin section near the Yellow River mouth'
