| 摘 要： | 通过对铜陵水系沉积物重金属形态分析实验,研究了重金属各种形态在沉积物中分布特征。分析结果显示,矿区水系沉积物中Cu、Pb、Zn、Cd等重金属含量都显著的高于对照样品,水系已经受到重金属的污染。提出了防治和改善铜陵地表水环境污染的措施。

| Abstract: | Distribution characteristics of the heavy metal species in sediments by sequential extraction procedure for evaluation of the forms of heavy metals in sediment in Tongling mining area. The results show that the contents of Cu, Pb, Zn and Cd in sediments of mining area are significantly higher than the normal values and have caused heavy pollution. Soluble copper, soluble lead, soluble, exchangeable, carbonate-bound, and organic matter-sulfide bound zinc, manganese with soluble, exchangeable, carbonate-bound, and Fe-Mn oxides-bound forms are also bio - available. Primary strategy of strengthening the water system's self-purification of Tongling was put forwards for the improvement of the water system in Tongling mining areas.
