| Abstract: | The concentrations of Co,Cr,Cu,Mn,Ni,Pb,Zn and V in 78 urban topsoil samples collected from inside the Second Ring Road in Xi'an were measured by X-ray fluorescence spectroscopy.The spatial variability of eight heavy metals was identified by geostatistical analysis with the aid of GIS tools.And correlation coefficient analysis,factor analysis and cluster analysis were used to analyze the data and to identify the possible sources of these heavy metals.The multivariate analytical results show that the spatial... |
