摘　　要：对巢湖水体和湖泊沉积物的重金属(Cu、Pb、Cd、Zn、Fe、Mn、Cr)含量进行了抽样测定,并分别对水与湖泊沉积物的重金属(Cu、Pb、Cd、Zn、Fe、Mn、Cr)的污染状况进行了评价,结果表明:巢湖水质较清洁,除Fe为Ⅴ类标准、巢湖湖心Zn属于Ⅱ类标准外,其他点重金属均达到Ⅰ类标准,但底泥中Pb、Cu、Cr、Zn污染相对较严重。The pollution from the heavy metals （Cu, Pb, Cd, Zn, Fe, Mn and Cr） to the water of Chaohu Lake and the pollutant distributions were studied through the analysis of these heavy metals in ,,sediments from the bottom of the lake and the pollutant state was evaluated. The analytical results showed that the water quality of Chaohu lake was comparatively clean. Apart from Fe the ground-water＇ standard was at the fifth level, the other all were confonned at the first level and the second level. Among these heavy metal pollution such as Cu, Pb, Cr and Zn were more serious.
