摘要
为了掌握四角田矿新鲜煤矸石和煤矸石山周围土壤的重金属污染状况,使用原子吸收分光光度法对新鲜煤矸石和土壤样品中的重金属进行分析,用Hakanson潜在生态危害指数法,对该矿区煤矸石山周围土壤重金属生态风险进行评价,结果表明:煤矸石山周围土壤存在重金属污染,有着严重的生态风险。
In this paper, heavy metals in coal gangue and soils around coal gangue dump of Sijiaotian mine are analyzed by atom absorption spectrometry method. Ecological risk index method presented by Hakanson is used to assess the potential e- calogical risks of the soils. The results show that there exist serious ecological risks in the soils around coal gangue dump of Sijiaotian mine.
