Abstract
The content of lead in urban street dust of Shanghai is studied, and Kriging analysis is applied to analyze the spatial distribution of lead in street dust of urban area. The range of lead content in street dust of urban area is 28-4443 mg·kg-1, with the average value of 264 mg·kg-1, which is 10.4 times of the soil background value in Shanghai; The range of lead content in the street dust of suburban towns'centers is 155-364 mg·kg-1, with the average value of 237 mg·kg-1, which is 9.3 times of the soil background value. The lead content in urban area within the inner ring is 359 mg·kg-1. The lead pollution centers in urban area locate mainly in commercial area and major roads, where the average content of lead in street dust is 642 and 520 mg·kg-1 respectively. The assessment results show that the lead pollution in urban street dust of Shanghai is generally at middle pollution level, and the lead pollution in urban area within the inner ring reaches middle to high pollution level. The results are expected to provide important scientific basis for the urban environmental pollution control and city planning of Shanghai.
