| 摘 要： | 以三峡库区重庆主城区段水体底泥为研究对象,对其重金属污染特征进行调查研究与对比分析;结果表明:三峡库区重庆主城区段底泥重金属污染主要是长江段,嘉陵江段污染较轻微,主要污染元素为Cu,Pb、Zn,其含量与背景值相差不大,重金属污染程度综合排序为CuZnPb,各重金属含量都是在70~90 cm深度之间达到最大值,主要污染河段为珊瑚坝、磁器口和广阳坝河段;与前人研究的五大湖区的结论进行对比表明,由于Cu的浓度很高致使研究区域潜在生态危害指数R I高于五大湖。

| Abstract: | Pollution characteristics of heavy metals in sediment of Chongqing urban section of Three Gorges Reservoir are investigated and analyzed.The results have shown that the main section of heavy metal pollution is Yangtze River,and Jialing River is not serious.Cu is the main pollution element,and the content of Pb,Zn is similar to the background value.The order of the analyzed heavy metals arranged from highest to lowest pollution degree is Cu> Pb >Zn.On the vertical direction,70 ~ 90 cm heavy metals content in... |
