【摘要】 为了解矿山的开采、冶炼对周围水环境的影响,对贵州省杉树林铅锌矿、榨子厂铅锌矿、赫章县后河土法炼锌区、万山汞矿周围水体的重金属(Cr、Mn、Fe、Cu、Zn、As、Se、Cd、Pb)含量进行了测定。结果显示水流对矿区尾渣堆的冲刷可以导致河水中悬浮颗粒物迁移很远,溶解态重金属含量主要受到悬浮颗粒物释放的影响。颗粒物少的河水溶解态重金属含量低,如榨子厂和万山;颗粒物多的河水则溶解态重金属含量高,如杉树林和赫章后河。更多还原

【Abstract】 The heavy metal (Cr, Mn, Fe, Cu, Zn, As, Se, Cd, Pb) concentrations in rivers around the Shanshulin Pb-Zn mine, the Zhazichang Pb-Zn mine, the Hezhang smelting area, and the Wanshan Hg mine were determined. Dissolved heavy metal concentrations are dominantly affected by suspended particulate matter in water. In Zhazichang and Wanshan, the existence of little suspended particulate matter in water gives rise to low dissolved heavy metal concentrations, while in the Shanshulin and Hezhang smelting areas the existence of much suspended particulate matter in water results in high dissolved heavy metal concentrations.更多还原
