摘　　要：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。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.
