| 摘 要： | 孟定盆地出现水砷异常由三类因素共同作用引发：汇水区砷背景高,有色金属采选冶过程排放含砷重金属导致砷二次污染,盆地地球化学环境利于砷积累。形成环境具一定的代表性,区别于我国已发生的饮水型盆地砷病病区。

| Abstract: | The As anomaly in the waters of Mengding basin is caused by 3 factors. The As setting is high in the drainage area. The discharge of As - bearing heavy metal in the mining, washing and metallurgical extraction of nonferrous metal, which results in the secondary pollution of As. The geochemical environment of the basin is advantageous to the As accumulation. The formation environment is representative, which is different from that of the As disease area in the basin of drinking water type in China. |
