[Objective] The objective of the study is to investigate heavy metal pollution and possible sources of heavy metals in surface dust in coach stations of Xi'an City, in order to provide support for improving the environment in coach stations of Xi'an City. [Methods] Dust samples were collected from 20 representative coach stations in Xi'an City and the concentrations of Cu, Mn, Ni, Pb, V, and Zn were measured by X-Ray fluorescence spectroscopy. Pollution level and environmental risk of heavy metals in the dust were assessed using the geo-accumulation pollution index and the potentially ecological risk index, respectively. Correlation coefficient analysis, principal component analysis and cluster analysis were used to identify the possible sources of these heavy metals. [Results] The mean content of Cu, Pb and Zn in the dust was 36.3, 107.7 and 113.5 mg/kg, respectively, which were significantly higher than their background values in soil in Shaanxi. The geo-accumulation index results indicated that the pollution level of Pb was medium, while other heavy metal pollution belonged to low-level. The potentially ecological risk index showed that the surface dust from coach stations was moderately polluted, and have medium ecological risk. [Conclusion] Source identification results suggest that Cu, Mn and Ni in the surface dust mainly came from nature and traffic, Pb and Zn mainly came from automobile exhaust emissions and worn-out parts, and V mainly came from the nature.
