Advances of dynamics model for heavy metal solute transport in aquifer

On the basis of summarizing the study of the heavy metal pollution at home and abroad, the authors of this paper reviewed the development of dynamics model for heavy metal solute transport in aquifer, and summed up the calculation methods of the model. The authors also discussed the determination of model parameters and the influences of temperature, pH, pore-water velocity, organic matter and colloid, soil heterogeneity on the determination of parameters. At last, the authors pointed out the main problems existing in the study on the transport process of heavy metal solute in aquifer, and looked forward to the study that needs focusing on in the field.
