Abstract This paper is based on a study of the urban dust in Xi'an City, especially the environmental geochemical anomaly of lead in the street dust. Five environmental geochemical pollution sites were selected, i.e., Xixinjie, Anyuanmen, Longshoucun, Fangzhicheng and Zhonglou. The causes for the formation of environmental anomalies of lead are tentatively interpreted in this paper.
