河蚬对沉积物中持久性有机污染物生物富集及迁移转化影响作用研究进展

Research Progress on Effects of Asian Clam(Corbicula Fluminea)on Bioaccumulation,Migration and Transformation of Persistent Organic Pollutants in Sediments

简述了河蚬对沉积物持久性有机污染物(POPs)的生物富集、迁移转化、沉积物微环境以及生物有效性的影响与研究进展,指出目前的研究多集中于水相以及河蚬单个种群的影响。提出今后应在河蚬对全沉积物影响、河蚬在“水-沉积物-水生生物”生态系统中的影响方面进一步深入研究,并从分子生物学角度分析新型污染物对河蚬的生物放大作用。

The effects of Asian clam(Corbicula fluminea)on bioaccumulation,migration and transformation of persistent organic pollutants(POPs),sediment microenvironment,and bioavailability of POPs in sediments are reviewed and the research progress is summarized.It is pointed out that most of the current studies focus on the effects of water phase and individual population of Asian clam.It is suggested that further studies should be conducted on the effects of Asian clam in the whole sediment and the“water-sediment-aquatic”ecosystem,and the biological amplification effects of Asian clam for new pollutants should be analyzed from the perspective of molecular biology.
