This work was carried out to investigate the pollution of heavy metals and pH in soil, collected from the 156 sampling sites in 1987. 1. In the average contents of Cd, the highest value was 0.40 mg/kg in the Outskirt of Seoul area, the lowest value was 0.11 mg/kg in the Greenbelt area, and 0.21∼0.39 mg/kg in the other areas. 2. In the average contents of Cu, the highest value was 32.50 mg/kg in the Motorway area, the lowest value was 2.96 mg/kg in the Greenbelt area, and 9.53∼24.41 mg/kg in the other areas. 3. In the average contents of As, the highest value was 1.32 mg/kg in the Reclamated waste area, the lowest value was 0.31 mg/kg in the Greenbelt area, and 0.93∼1.32 mg/kg in the other areas. 4. In the average contents of Zn, the highest value was 27.33 mg/kg in the Center of city area, the lowest value was 9.97 mg/kg in the Greenbelt area, and 12.47∼25.23 mg/kg in the other areas. 5. In the average contents of Pb, the highest value was 125.25 mg/kg in the Motorway area, the lowest value was 12.99 mg/kg in the Farming area, and 17.01∼77.71 mg/kg in the other areas. 6. In the average contents of pH, the highest value was pH 7.08 in the Motorway area, the lowest value was pH 4.14 in the Greenbelt area, and pH 5.67～7.04 in the other areas. 7. The order of the distribution of heavy metals was Pb>Zn>Cu>As>Cd. There was significanthy correlation between Cd-Zn, Pb-Zn, Cu-Cd, Pb-Cu and Pb-Cd (p<0.01).
