| Abstract: | The mobility of soil heavy metals in soil-plant system depends on their specific chemical forms, binding states and soil environments,which reflects the degree of soil contamination and corresponding haz-ards to eco-environment and human health. Studies on the evaluating methods of soil heavy metal bioavail-ability help to realize the risk of soil heavy metal pollution and provide theoretical bases for soil remedia-tion. In this paper, the influencing mechanisms of soil physic-chemical character, properties of heavy met-als, plant species and rhizosphere effect, human activity and other factors on heavy metal bio-availability in soil-plant system are summarized. The application, advantages and disadvantages of the total prediction method, chemical extraction procedure, Free-ion Activity Model and biological evaluation method are sys-tematically summarized. Finally, some problems and development in the future in terms of heavy metal mo-bility and bio-availability in soil-plant system are put forward. |
