摘要
阐述了水体中一些微量毒性元素，如Pb, Hg, Cd, Cr, Se, Tl, As, Be, Al等的水化学特性，分析了它们的环境地球化学特征，并对自然水体中毒性微量污染物的来龙去脉以及对人体的可能危害性进行了初步的探讨。
The toxic trace contaminants in drinking water can cause public health ruin. The trace toxic contaminants in public water include not only organic chemicals, but also inorganic trace elements, for example, Pb, Hg, Cd, Cr, Se, Tl, As, Be, Al et al, The paper descants on the features of these toxic trace elements and discusses their geochemical characteristics from source area to aquatic environment.
