摘　　要：使用X射线荧光光谱法对某人口密集区道路灰尘样品中Cu、Zn、Pb、Ni、Cr 5种重金属元素含量进行分析。采用尼梅罗指数法、地质累积指数法评价了该区域5条道路灰尘重金属的污染现状。结果表明,该区域道路灰尘重金属的空间分布差异较大,5条道路除Ni元素和成功大道的Cr无污染外,其它道路灰尘重金属元素均有不同程度的污染。The dust contents of Cu, Zn, Pb, Ni and Cr on several regional roads are determined by x - ray fluorescence spectrometry. We evaluate the heavy metals pollution status about the dust on 5 roads in this area, by using Nemerow index method and geo - accumulation index. The results show that the spatial distribution of heavy metals in this area is quite different. All of the elements are polluted except Ni in all 5 roads and Cr in Chenggong Road.
