摘　　要：镉是一种毒性很强的重金属元素,常伴生于铅锌等硫化物矿床中。在这类矿床的开采过程中,镉很容易扩散到周围环境中并造成污染。文章以贵州省都匀地区牛角塘独立镉矿床为例,研究了矿区内水体、土壤、红薯中镉的分布特征,并开展了淋滤实验研究。结果表明:镉已对矿区环境造成了相当严重的污染,镉对该区环境具有巨大的潜在压力。Cadmium is a dangerous heavy element which can do great harm to the environment. It always exists in Pb-Zn sulfide ores and minerals an associated component. Cadmium is transferred into water, soil and plants along with the exploiting of ore. In the Niujiaotang Cd ore deposit, Cd is enriched to a super high extent. This paper is concerned mainly with the distribution pattern of Cd in water, soil and potato. An simple experiment was carried out in order to study the transferring ability of Cd from ores and minerals to the environment. The research results demonstrate that the environment around the mining area has already been polluted. The potential pollution effect is serious.
