| 摘 要： | 矿业活动是土壤重金属累积的重要原因之一。分析云南个旧锡矿区矿业活动区、与矿业活动区地质条件相同的矿业活动影响区和未受矿业活动影响的参照区表层土壤7种重金属元素之间的相关性,以参照区表层土壤重金属总量、参照区土壤重金属似背景值分别评价矿业活动对矿业活动区和矿业活动影响区土壤重金属的累积贡献量和贡献率。结果表明,矿业活动区重金属累积贡献率排序为PbZnAsCuCdCrHg,影响区重金属累积贡献率排序为PbZnAsCuCdCrHg,Pb、Cd、As、Zn、Cu与矿业活动关系密切,矿业活动区Pb、Cd、As均表现为极高累积和极高风险,应作为矿业活动治理的重点元素。

| Abstract: | Mining activity is one of the important factors responsible for heavy metal accumulation in soil. The authors analyzed the relationships between seven kinds of soil heavy metal elements in the Gejiu mining area and the influenced area whose geological conditions is the same as the mining area in comparison with areas unaffected by mining activities. The heavy metal accumulation values and rates of mining activities on soils in the mining area and the influenced area were evaluated one by one in the light of total heavy metals and background-like values in surface soil of the compared area. The results show that the heavy metal accumulation values are in order of Pb>Zn>As>Cu>Cd>Cr>Hg in the mining area and Pb>Zn>As>Cu>Cd>Cr>Hg in the mining influenced area. There is close relationship between Pb, Cd, As, Zn, Cu and mining activities. Pb, Cd and As, characterized by high accumulation and high risk, should be most emphatically controlled in the mining area. |
