초록

A long-term field demonstration experiment on selected stabilization methods to reduce the heavy metal mobility in farmland soil contaminated by heavy metals was conducted. The field demonstration experiment was established on the contaminated farmland with wooden plates (thickness = 1 cm), of which the dimension were width = 200 cm, Length = 200 cm, height = 80 cm, filled with treated soil, which was mixed with lime stone and steel refining slag except on control plot. Soil samples in the plots were collected and analyzed during the experiment period (6 months) after the installation of the plots. The field demonstration experiment results showed that the application lime stone at the ratio of 5% was effective for immobilizing heavy metal components in contaminated farmland soil.
