安徽铜陵林冲尾矿库重金属元素分布与迁移及其环境影响

The distribution and migration of heavy metal elements of Linchong tailings reservoir in Tongling, Anhui Province, and their environment effects

通过对铜陵凤凰山矿林冲尾矿库中重金属元素的空间分布特征及相关土壤、水系沉积物和植物中重金属元素含量变化的研究 ,初步了解尾矿重金属元素的空间变化和迁移规律 ,分析了其对周围环境的影响及潜在危害性 。

The Linchong tailings reservoir of the Fenghuangshan mine in Tongling of Anhui Province is one of quite a few tailings reservoirs there. In this paper, it was selected to study the distribution and migration of heavy metal elements. According to the changes of the heavy metal contents of the tailings reservoir and a comparison of the heavy metal contents between the tailings, the related soils, the river system sediments and the plants, the authors have found out the regularities governing the space distribution and migration of the heavy metal elements, discussed the environmental effects and latent harmfulness of the tailings, and pointed out the correct means for developing and utilizing the land in the mine tailings reservoir.
