| 摘 要： | 通过对鸡西柳毛石墨尾矿库及其周围土壤重金属元素含量的测定,分析、评价其重金属污染状况,研究其重金属污染、迁移特征及规律,为矿区污染土地的治理和生态恢复提供科学依据.结果表明:鸡西柳毛石墨尾矿库综合污染指数平均值为19.15,属重度污染源;CA和Hg是石墨尾矿库的主要重金属污染元素.尾矿库周围土壤已受到严重污染,综合污染指数达到尾矿库的2.73倍,Cd、Hg、Ni是造成尾矿库周围土壤污染的主要重金属元素,下层土壤的污染程度高于表层土壤.5种重金属元素在不同介质中的迁移能力存在差异. |
| 关 键 词： | 石墨尾矿库 土壤 重金属 污染特征 评价 |

| Abstract: | The heavy metal elements of the Liu-mao graphite tailings reservoir and its surrounding soil in Jixi were measured,the status of heavy metal pollution were analyzed,the characteristics and laws of heavy metal pollution and migration were studied,scientific basis for ecological restoration and land control of polluted mine site were provided.The outcome shows that the average comprehensive pollution index of Liu-mao graphite tailings reservoir is 19.15,the graphite tailings reservoir is in heavy pollution,Cd and Hg was the major heavy metal element.The surrounding soil of Liu-mao graphite tailings reservoir had been polluted seriously,its comprehensive pollution index is 2.73 times of the index of graphite tailings reservoir,Cd,Hg and Ni being the major heavy metal elements,the heavy metal pollution degree of subsoil was higher than surface soil.The migrating ability of 5 heavy metal elements was difference in various media. |
| Keywords: | graphite tailings reservoir soil heavy metal pollution characteristics evaluation |
