摘  要：
选择采集钼矿区交通运输干线周边菜地土壤样本180个,采用HNO3-HF-HClO4混酸对土壤样品进行处理,运用等离子体发射光谱仪(ICP-OES)测定土壤样品中Mo、Pb、As、Hg、Cr、Cd、Zn、Cu、Ni的含量,全面系统地评价土壤重金属污染现状,并进行元素形态分析,同时对矿区周边水域中重金属元素的含量也进行了分析测定。结果表明,钼矿区交通运输干线周边菜地土壤污染属于多金属复合污染,其中土壤重金属Cd、Hg污染较为严重;污染强度以菜地距运输干线0～50m最高,内梅罗综合指数为17.35,随距离增加污染减轻。重金属元素形态分析表明,0～50m菜地土壤范围Cd、Cr、Cu、Ni、Zn总量中化学形态分布为:残余态>有机结合态>氧化结合态>酸可提取态;As、Hg、Mo、Pb总量中化学形态分布为:有机结合态>残余态>氧化结合态>酸可提取态;50～100m范围内菜地土壤中重金属的化学形态分布大致为:残余态>有机结合态>氧化结合态>酸可提取态;100～150m范围内重金属总量中化学形态分布大部分为:残余态>有机结合态>氧化结合态>酸可提取态。土壤中Hg、Cd的有机结合态较高,可能主要来源于污灌及化学农药的施用以及塑料薄膜的使用。

摘  要：
The heavy metals pollution in vegetable soil around the transportation skeleton line in molybdenum ore areas was investigated. 180 soil samples were collected and treated with HNO3-HF-HClO4, then the contents of Mo, Pb, As, Hg, Cr, Cd, Zn, Cu and Ni were determined by ICP-OES and assessed systematically, and the contents of heavy metals in underground water of vegetable field were also determined. Besides, forms of the heavy metals were analyzed. The results indicted that the soil belonged to polymetallic compound pollution in which Cd and Hg were the most serious pollutants. The pollution was the heaviest in vegetable soil that was 0~50 m apart from the transportation line, with Nemerow index 17.35. We found that the Nemerow index reduced with the increase of the distance. The forms of Cd, Cr, Cu, Ni and Zn in 0~50 m vegetable field showed: residual fraction>organic fraction>oxidizable fraction>acid extractable fraction, but for As, Hg, Mo and Pb, organic fraction>residual fraction>oxidizable fraction>acid extractable fraction. Forms of heavy metals in 50~100 m vegetable field were residual fraction>organic fraction>oxidizable fraction>acid extractable fraction, while, in 100~150 m vegetable field, the residual fraction>organic fraction>oxidizable fraction>acid extractable fraction. Oxidizable fraction of Hg and Cd was higher.
