改进物元分析法在农田土壤重金属污染评价
|
摘要
[目的]进一步探讨铅锌矿区的开采对农田土壤中重金属的污染状况以及危害程度。[方法]以广西环江某铅锌金属尾矿区周边农田土壤作为研究对象,测定了重金属Cu、Zn、Pb、Cd含量,并对农田土壤样品重金属测定结果分别采用改进物元分析法、传统物元分析法以及潜在生态危害指数法进行综合评价和分析危害程度。[结果]改进物元分析法中中度污染程度以上的监测点占85.72%;传统物元分析法中不符合级别程度的监测点占85.72%;潜在生态危害指数法中严重级别以上的监测点占85.72%。[结论]铅锌金属矿区尾砂坝坍塌对周边农田土壤造成重金属污染危害。
[Objective] The research aimed to further explore the pollution of heavy metals in farmland soils by the exploitation of Pb-Zn mining area and the degree of its harm. [Method] Takeing the farmland soil around a Pb-Zn metal tailing area in Huanjiang of Guangxi as the research object, the content of Cu, Zn, Pb and Cd were determined. The results of the determination of heavy metals in farmland soil samples were comprehensively evaluated and analyzed by means of improved matter-element analysis, traditional matter-element analysis and potential ecological hazard index method. [Result]The monitoring points of improving the degree of moderate pollution in the matter-element analysis method accounted for 85.72%; the monitoring point of non-conforming level in the traditional matter-element analysis was 85.72%; the potential ecological Hazard index method had 85.72% of the monitoring points above the severity Level.[Conclusion]The collapse of tailings dam in Pb-Zn metal mining area caused heavy metal pollution to surrounding farmland soil.
