The concentrations of Co, Cr, Cu, Mn, Ni, Pb, Zn, and V in urban topsoil samples collected from inside the Xi'an Second Ringroad, northwestern China were measured by X-ray fluorescence spectroscopy. Correlation coefficient analysis, factor analysis and cluster analysis were used to analyze the data and to identify the possible sources of these heavy metals. Three main sources of these heavy metals were identified. Pb and Cu originate from traffic. Co, Cr, and Zn mainly derive from industry sources, traffic and garbage, while Mn, Ni, and V mainly originate from natural source
