摘要:沉积物是重金属在环境中迁移转化的重要媒介。生物扰动能改变沉积物的物理化学组成,从而影响沉积物中重金属的赋存形态和迁移转化特征。文章介绍了生物扰动的定义和种类,生物扰动的影响因素以及扰动过程中影响污染物释放的主要因素,并综述了近年来生物扰动对沉积物中重金属镉、铜、锌、铅和其他重金属的环境行为影响。

Abstract:Heavy metal contaminated sediments may pose a risk for the ecological quality of surface waters. Bioturbation can change the physical and chemical properties of the sediment, and therefore have significant effects on the occurence, migration and transformation of heavy metals in the sediment. This paper introduced the definition and types of bioturbation, the main factors influencing the pollutant release during the process of the disturbance, and reviewed bioturbation effects on the environmental behavior of heavy metals in sediments such as copper, zinc, lead, cadmium and other heavy metals.
