太湖沉积物中重金属的测定及环境意义

Determination of Heavy Metal Contents in the Sediments from Taihu Lake and Its Environmental Significance

摘要: 通过对太湖地区水域湖泊沉积物中重金属含量的抽样测试，描述了太湖水域重金属（Ag、As、Cd、Cr、Cu、Hg、Ni、Pb、Zn等）元素的污染状及其分布，结果表明：太湖沉积物中重金属含量北部明显高于东部，来自太湖北岸城镇和工业区的未处理工业及生活污水，对太湖北部水域造成的重金属污染程度远高于以养殖业为主的东太湖及湖心水域。

Abstract: The pollution from the heavy metals (Ag, As, Cd, Cr, Cu, Hg, Ni, Pb, Zn, etc.) to the water of Taihu Lake and the pollutant distributions were studied by analysis of these heavy metals in sediments from the lake's bottom. The analytical results show that
