【摘要】 通过分析河口滨岸潮滩各介质中多氯联苯(PCBs)和有机氯农药(OCPs),研究其在表层沉积物中的污染水平、形态组成与来源,以及动植物体中PCBs和OCPs富集的季节性差异;并对PCBs和OCPs在多介质中的迁移规律及其生物有效性进行了探讨;此外,还运用了多种方法对长江口滨岸不同介质中PCBs和OCPs的生态风险进行了综合评价。更多还原

【Abstract】 Through analyzing polychlorinated biphenyl (PCBs) and organochlorine pesticide (OCPs) in multi-phases from the Yangtze Estuarine and coastal ecosystem for the first time, the results have revealed the contaminated levels, various constituents and sources of PCBs and OCPs in surface sediments, and found the seasonal variations of PCBs and OCPs accumulated in plants and sediment-dwelling animals. The present study also discussed the transfer mechanisms of PCBs and OCPs and their bioavailabilities in multi-phases. Moreover, the study predicted and assessed the environmental effect of PCBs and OCPs on the Yangtze estuarine and coastal ecosystem.更多还原
