摘要：

By the investigation of 23 samples from street pavement dust in Suzhou city, this article analyzed the the particle size distribution characteristics of lead in street dust, using the X-Ray fluorescence spectrometry and single factor method. The results show that: the lead concentrations in the particle size ranges of <75 mu m and 75-150 mu m are higher than the other ranges, which indicates lead is enriched in fine grain size; the particle size ranges of 250-500 mu m is at mild level of lead pollution, and the other particle size ranges are at medium level.
