Abstract Various metal pollutants transported from certain sources may considerably contaminate the soil environment. It was reported that transportation related pollution closely associated with distance, freight volume and traffic emissions. However, effect of topography on heavy distribution in soils along routes has received little attention. In present investigation, arable two selected for mineral products were studied to characterize topographic impacts their level pollution. Soil samples collected within a 5‐m radius following ‘S’ sampling procedure using spatial autocorrelation analysis. The descriptive statistics showed most (Pb, Zn, Cu Cd) concentrations exceeded background value Zhejiang Province contents metals Area B, plain, generally higher than A, valley hilly region. LISA maps all did not have similar B. A contaminants Cu, Cd Pb had structure located route. topography, found decrease increasing distance road. this valid B where concentrated could be derived multiple sources, particularly emissions nearby local industry.
