  • Based on a study of the background values and enrichment degrees of some trace elements in urban dust in Xi'an City,environmental anomaly areas in Xi'an were outlined,and the element characteristics of various environmental anomaly areas were analyzed.The paper points out that the main pollution-producing elements in urban dust in the anomaly areas are Hg,Ag,Sb and Zn,while the other elements in different anomaly areas are also enriched to different degrees.On the basis of these results,the distributions of trace elements in different anomaly areas were evaluated.
