摘    要:本文从湘江所处的地质环境和矿产方面,讨论了湘江受Pb、Cd、Cr、As、Hg等元素污染的情况,并得出地质体中该五种元素在水中溶解甚微的结论,说明湘江污染主要来自工厂。为区别自然污染和人为污染,经初步计算,确定了湘江水体中重金属元素自然背景值。

Abstract: In view of the geological environments and mineral resources in thevicinity of the Xiangjiang River, water pollution problems were discussed.It was concluded that the solubility of Pb, Cd, Cr, As and Hg minerals isvery small and that water pollution may not be influenced by geologicalenvironments and mineral resources, but most probably caused by the factoriesand plants. In order to discriminate between natural pollution and man--madepollution the natural bakcgrounds of heavy metal elements in the XiangjiangRiver were estimated in this paper.
