某铅锌矿开采区土壤镉的污染及有关界面过程

Contaminative and Interfacial Processes of Soil Cadmium in a Lead-zinc Mining Area

本文根据不同的采样设计 ,定量推算并证实了某铅锌矿区采矿裸露岩矿的加速风化过程、堆置于土壤上的采矿碎石和尾砂的雨水淋洗过程、采矿散发的含镉物质通过大气的回降过程以及有关的界面过程的存在 ,和对该矿区土壤镉污染的重要贡献 。

In a lead-zinc mining area accelerative weathering of rocks uncovered at soil interface by mining, leaching of mining breakstones and milltailings piled on surface soils by rainwater, atmospheric precipitation of cadmium-containing materials emanated from mining, and relevant interfacial processes were quantificationally verified based on different sampling designs. These processes significantly contributed to cadmium pollution of the soils in the mining area, indicating the damage of soil-health quality.
