土壤中重金属元素运移规律研究进展

Research Progress in Migration Regularity of Heavy Metal Elements in Soil

在全球气候变化及空气污染严重加剧的前提下,酸雨会加速土壤中的重金属离子以溶解态的形式存在于土壤溶液中,从而使土壤肥力下降,造成土壤环境的污染。因此,土壤中的重金属元素的运移成为其污染土壤的主要原因之一,对土壤中重金属的运移特征及其影响因子进行了综述,得出重金属在土壤中的运移特征除了与重金属污染物本身的活性有关外,更取决于它所进入的土壤的性质。

As global climate warms and air pollution aggravates, acid rain can increase the heavy metal content in soil as ion form, which will decline the fertility of soil and pollute the soil. Therefore, migration of heavy metal elements in soil becomes one of main reasons to contaminate soil. In this paper, features of the migration of heavy metals in soil and its influencing factors were analyzed. The results show that, migration characteristics of heavy metals in the soil are related to their own activities of heavy metal pollutants, and it also depends on the soil character.
