Abstract The contents of As, Cr, Pb, Cu, Zn and Ni in soil of the populous place, were determined by x - ray fluorescence spectrometry. The heavy metals pollution of soil was evaluated by using single pollute index , synthesis pollute index, geoaccumulation index and potential ecological risk index, and the results showed that the populous place was in the state of slight pollution and ecological risk.%使用X射线荧光光谱法对某人口密集区表层土壤样品中As、Cr、Pb、Cu、Zn、Ni共6种重金属元素含量进行分析.采用单项污染指数法、综合污染指数法、地质累积指数法、潜在生态危害指数法评价了该地区土壤重金属的污染现状.结果表明,该人口密集区属于轻度污染、低度生态风险.
