江西某铀矿区土壤中Cr污染评价
|
摘要
利用等离子体质谱仪测定铀矿区133个土壤样品中重金属Cr的含量,重点对铀矿区土壤中重金属Cr的含量及其空间分布特征进行研究。结果表明,整个矿区土壤重金属Cr的含量为10.04~93.9 mg/kg,平均值为51.44 mg/kg。各区域土壤重金属含量大小分别是尾矿坝下游>在采矿区>整个矿区>含矿未采区>尾矿坝。运用单因子污染指数评价法进行评价,表明在整个矿区一半以上的区域都属于轻度污染,正在采矿区四分之三的区域都属于轻度污染,尾矿坝下游也有轻度污染,尾矿坝和含矿未采区均无污染。
ICP-MS was used to determine the contents of heavy metal Cr in the 133 soil samples which was taken form a uranium mine,East China. In focusing on studied the contents and its spatial distribution characteristics of heavy metals Cr in samples. Results show that the concents of Cr in the soil in whole mining area were 10. 04 ~93. 9 mg / kg,with a mean of 51. 44 mg / kg. The contents of Cr in the soil in regional respectively. were the downstream of tailings dam mining area > whole mining > not mining which had the mining area > tailings dam. Using the single factor pollution index,showed that more than half of the whole mining area were mild contamination,three-quarters of the mining regions were mild contamination,the downstream of tailings dam also had mild contamination,the tailings dam and not mining which had the mining area were non-pollution.
