摘要
通过对演马矿矸石山周围的表层土壤污染状况进行调查和监测分析,总结出Cd、Cr、Zn、Pb、Cu等重金属元素在矸石堆周围土壤中的分布状况和变化规律。研究表明,演马矿矸石山周围土壤Cd为轻污染;Cr、Zn为中污染,其含量与矸石堆距离呈非线性负相关关系;Pb污染受交通影响波动较大,土壤受Cu污染不明显,均为安全级。
The paper deals with the investigation of soil pollution around the gangue dump in Yanma mine of Jiaozuo city in Henan Province. The distribution and variation patters of Cd,Cr,Zn,Pb and Cu in top soil around the dump were discussed. The studies showed that the soil around the dump was polluted slightly by Cd,moderately by Cr and Zn and Pb pollution was greatly influenced by traffic. The Cr and Zn pollution are in non-linear negative relationship with the dis- tance to the gangue dump. The environmental impact has been assessed in the paper.
