摘　　要：国外城市街尘重金属污染研究较早,国内相关研究虽起步较晚,但发展迅速。本文搜集了近10a来中国城市街尘重金属污染研究的主要成果,从重金属含量、空间分布特征、赋存形态、污染来源以及污染影响评价等方面进行详细梳理,并就未来我国城市街尘重金属污染研究的发展趋势提出了一些建议。Research on the contamination of heavy metals in urban street dust has set an early step in the foreign countries. The related researches started relatively late in China, but they boom rapidly in recent decades. This paper collected numerous docu- ments on this subject conducted in China in the past decade and thoroughly elaborated on the following aspects： heavy metal concentration and spatial distribution, grain size effect, chemical forms and environmental evaluation. The authors also pro- posed some suggestions on the future development tendency of contamination of heavy metals in urban street dust in China.
