DOI: 10.3724/SP.J.1145.2009.00515, PP. 515-518

Abstract:
采用原子吸收分光光度法对湖北武汉南湖柱状沉积物中的6种重金属(cd，cu，cr，mn，pb和zn)进行测定.结果表明，柱状沉积物中各种重金属的平均含量(w/mgkg-1，dm)分别为cd0.155，cu47.0，cr147.8，mn1026.5，pb55.7，zn132.1.水平分布，重金属的最大含量出现在点ⅳ和点ⅰ，且平均含量也高于其他的点；垂直分布，最大含量出现0~5cm或5~10cm的沉积层，随沉积深度的增加而降低.这些结果表明外源污染对沉积物的重金属负荷具有重要影响.应用地质累积指数igeo值对重金属污染状况进行评价，结果表明，重金属的污染主要是cr和cd，其中cr的最高含量(w/mgkg-1，dm)为231.9，cd为0.348；重金属的污染程度较轻.图2表1参20
