| 中文摘要: |
| 对某金属矿尾矿库流域内的土壤、植物等进行调查取样,确定尾矿库对周边环境的污染范围和污染趋势,对尾矿库所在流域的污染程度、污染特征等进行评价与分析,探明尾矿库是否对周边及下游植物造成严重污染。研究结果表明,该尾矿库的土壤砷元素含量超标严重,总氰化物、锑、镉、汞、锌元素含量也略有超标,尾矿库流域的污染区以尾矿库为中心,向周边由近及远污染程度递减；尾矿库的周边植物样品中各检测元素含量均未超标,可以推测尾矿库尚未对周边及下游植物造成严重污染。这些分析可以为其它尾矿库污染方面的研究提供依据。 |
| 英文摘要: |
| Soil and plants in the basin of a metal mine tailings pond are investigated and sampled. Pollution range and trend of the tailings pond to surrounding environment are determined. Pollution degree and pollution characteristics of the basin where the tailings pond is located are evaluated and analyzed, and whether the tailings pond causes serious pollution to the surrounding and downstream plants are verified. Research results show that arsenic content in the tailings soil exceeds limit bid badly, total cyanide, antimony, cadmium, mercury, zinc contents are also slightly out of limit. The pollution area is close to the tailings basin that is the center of the pollution area., and the pollution extent decreases outwards from the center. The content of each detected element in the plant samples around the tailings pond did not exceed the limits, so it can be concluded that the tailings pond has not caused serious pollution to the surrounding and downstream plants. These analyses can provide a basis for study of pollution in other tailings ponds. |
