This study was carried out to examine the effect of heavy traffic on chemical properties of soil in roadside trees of Daejeon city. Soil samples at 0~10cm and 10~30cm depths were collected from soil of the roadside trees, Platanus occidentalis. and Ginko biloba. Soil pH in heavy traffic regions were around 7.0 at 0~10 cm and 10~30cm soil depths because of spraying of calcium chloride for snow moving. The concentrations of Fe, Cd, Cu, Zn, and Pb in soil were higher in heavy traffic regions(Daejeon Station and Daehwa Industrial Complex) than in light traffic region(Chungnam National University). The result could be from rubbing and wear of car tire and metals when they travel.
