Abstract: Spatial distribution of potentially toxic trace elements (PTEs) concentrations in soils is essential for pollution and risk evaluation. In this study, 33 samples were collected downstream of a lead–zinc mine in Southern China. Contamination factors (CFs) of As, Pb, Zn, Cu, Cr, and Ni were all near 1 (low contamination), while 12% of the sample sites showed high contamination of Cd (CF>6). The highest concentration of Cd was about 40× natural background value of study area. Variogram analysis allowed detecting the principal direction of variation. High soil pH value and rocks could prevent PTEs vertical migrating in the mountain. The spatial distribution of Zn and Cu may be resulted from lateral transportation with soil erosion.
