摘要
调查了邯郸市九龙矿矸石山周围地表土壤中重金属的元素的含量。并通过单因子污染指数和N.L.Nemerow(内梅罗)指数法对矸石山周围土壤进行污染评价。结果表明,矸石山附近的土壤都符合土壤环境质量标准二级标准中(pH>7.5、农田、旱地)的重金属指标。背景土壤与矸石山周围土壤的重金属含量相差较小,主要与煤矸石中重金属含量偏低有关。由于该矿煤矸石对周围土壤环境影响程度较小,煤矸石中重金属含量偏低所以应尽量增加对煤矸石的综合利用,从而减少煤矸石对土地的压占。
We investigated the heavy metals contents in the surface soil around the mine rock dump in Handan Jiulong coal mine and assessed the soil pollution by single-factor contami- nant index and nemerow index method.The result showed that the heavy metals in the surface soil around the mine rock dump attained the Grade ]I Environmental quality standard for soils （pH〉7.5,farmland,dry land）.The background soil and the surface soil around the mine rock dump have a small difference.It is related to the low heavy metals contents.The coal gangue impact the soil around the gangue to a lesser extent and the heavy metals contents of coal gangue is low it should be to maximize the comprehensive utilization of coal gangue. Thereby reducing the pressure accounted gangue of land.
