生物扰动对沉积物中污染物迁移转化影响的研究进展

Advancein Bioturbation Effect on Transformation and Migration of Contaminantsin Sediments

生物扰动可以改变沉积物的理化性质和生物地球化学作用,从而促进或减弱污染物从沉积物向水中的释放,而沉积物中污染物的迁移转化规律对于指导环境修复以及评价污染物的潜在风险均大有裨益。本文介绍了生物扰动的定义,并综述了近年来关于生物扰动对沉积物中污染物迁移转化影响方面的研究。

Bioturbation could change the physical and chemical properties of sediments and biogeochemistry process, and then promote or inhibit release of contaminants from sediments into water, which plays an important role in environmental modification and environmental risk assessment of contaminants. The definition of bioturbation was given and recent advances of bioturbation effect on migration and transformation of contaminants in sediments were comprehensively reviewed.
