| This study was carried out to find out the heavy metal contents and the physico-chemical properties for the improvement of dredged soils which widely exist in lowlands of Korea. At first all the average heavy metal contents were close to background level and were much lower than concern level of the Soil Environment Conservation Act of Korea. And the results of physical analyses of soils showed on the average $2.46~2.74 Mg/m^3$ in Particle density, $0.45~2.45 kg/kg$ in soil water contents, $0.34~0.90 Mg/m^3$ in bulk density, $0.67~0.87m^3/m^3$ in porosity, $2.18 imes10^{-5}~1.20 imes10^{-8} m/s$ in saturated hydraulic conductivity, R0.12~0.65 m^3/m^3$ in available water contents. Finally the results of chemical analyses of soils showed on the average $6.5~8.2;in; pH,;5~48 g/kg;in; OM,;0.48~4.51g/kg;in;T-N,;19~25mg/kg$ in available phosphate, $0.28~11.80 dS/m;in;EC,;8.7~38.1cmol/kg$ in CEC, respectively Accordingly, the physicochemical properties of soils ought to be analyzed accurately before dredging for effective using of dredged soils. And it will be more effective, if the dredged soils are used with proper balance among each content of components with consideration to the physicochemical properties of common soils. |
