| 摘 要： | 为了解煤矸石堆场对其周围土壤的重金属污染程度,对某矿区3座煤矸石堆场周围的土壤样品进行采样分析,并采用Hakanson的重金属潜在生态风险指数法,对煤矸石堆场周围土壤中重金属的潜在生态风险性进行了评价。结果说明,露天煤矸石堆场对周围土壤造成了重金属污染,存在着一定的生态风险,但风险程度为低水平。Cd元素的单个污染物污染程度最高,并且也是最主要的潜在生态风险因子。

| Abstract: | In this paper, heavy metal elements were quantitatively analyzed in the soils around 1he three coal gangue yards. Potential ecological risk assessment of heavy metals pollution with the soils around the coal gangue yard was performed by using Hakanson＇s ecological risk index, the results indicated that heavy metal pollutions occurred in the soil around coal gangue yard and there are certain ecological risk, but risk is low. Cd pollution is the Highest single pollutant elements and also the most important factor potential ecological risk. |
