An Investigation on the Effect of Stabilization Methods and Leaching characteristics of Heavy Metals in Paddy Soils contaminated by Heavy Metal under Submerged Condition

담수조건에 따른 토양 내 중금속 용출특성과 안정화공법의 효과 검토

In order to investigate on the effect of stabilization methods for rice paddies contaminated by heavy metals, a series of lab-scale model test was carried out by applying the characteristics of submerged Paddy soil. To perform the lab-scale model test, columns were made by acrylic with the dimension of diameter=10cm, thickness=0.5cm and were filled with soils which was contaminated were mixed with stabilization agents(lime stone 5% and steel refining slag 5% respectively). To manipulate the reduction condition, soils in the columns were submerged with distilled water. And then soil water and subsurface water in each column were sampled in the regular term and analysed the various physical and chemical properties.
