Effect of Dissolved Organic Matter on Migration of Heavy Metals in Soils

The north most representative cinnamon soil was selected as the tested soil. The study considered the effect of dissolved organic matter on migration of Cu, Cd, Pb and Zn in soils by column experiment. Migration and transformation model was built which based on the soil solute transport model. It is important for the prediction of the temporal and spatial distribution of pollutant, and help to prevent pollution of heavy metal. This study can provide theoretical guidance for land use of the solid waste.
