矿区农田土壤的重金属污染

Heavy metals pollution of farmland soil in mine area

在室内实验的基础上,检测了东梁矿区农田表层土壤及剖面土壤中和农作物及其果实中Cr、Ni、Pb、Cu、Zn、Cd等重金属的含量,并对土壤中重金属之间的相关性进行了分析。对东梁矿区土壤及粮食作物的重金属污染情况进行了评价,确定了污染级别。研究了东梁矿区土壤剖面上重金属的垂直分布规律和农作物对重金属的富集状况,并分析了稻米重金属含量的影响因素。

By many experiments, the contents of heavy metals, such as Cr, Ni, Pb, Cu, Zn, Cd etc., of surface layer soil and section soil and of crops and fruits from farmland in Dongliang Mining area were checked and tested. The correlation between heavy metals was analyzed. The situation of heavy metals pollution of soil and grain crops in this area to get pollution level was evaluated, The heavy metals vertical distribution discipline of section soil and the enrichment states of crops to heavy metals were studied, and the influence factors of heavy metals contents in rice corn were analyzed.
