Abstract: Based on the theory formula and experimental data, the migration and concentration distribution of heavy metal ions in the environment after a number of years were evaluated by using the parameters in suitable scope. Effects of time, w ater flux density, and distribution coefficients of metal ions on the migration and concentration distribution of heavy metal ions were also simulated in soil. The results indicate that the migration of heavy metal ions in soil is mainly d ominated by the water flux density and distribution coefficients of the metal io ns sorption to soil. The concentrations of the metal ions in soil increase wit h increasing time. The results are important for the evaluation of metal ions po llution to the environment.

Key words: metal ion, soil, migration pollution, simulation study
