【摘要】 多氯联苯是斯德哥尔摩公约首批禁止的持久性有机污染物之一.残留在环境中的多氯联苯,由于其亲脂特性可在生物体内进行生物积累以及在食物链中产生生物放大效应,并在肝脏中代谢产生羟基多氯联苯、甲磺基多氯联苯、多氯联苯硫酸盐等.代谢产物在水生生物体内会产生与内分泌相关的毒性作用,继而导致的水产品质量安全问题,引起了国际范围的持续关注.本文从多氯联苯代谢产物的定性定量分析方法、毒性效应及机理、多氯联苯生物转化机制等方面展开综述,并对目前全球范围内关于水产品中多氯联苯代谢产物同系物类型、残留水平以及对其影响水产品质量安全的研究进展进行了全面的总结概述.更多还原

【Abstract】 Polychlorinated biphenyls( PCBs) are one of the first 12 persistent organic pollutants prohibited by the Stockholm Convention in 2001. As persistent contaminants in the environment,PCBs can be bioaccumulated in organisms and biomagnifed in the food chain due to their lipophilic properties,and are biotransformed into metabolites including hydroxylated PCBs,methyl sulfonated PCBs and PCB sulfates in the liver. These PCB metabolites-generation pollutants may have toxic effects involved with endocrine disruption in aquatic organisms,lead to consequent problems of aquatic products,and this have attracted sustained attention worldwide. In this paper,we reviewed the progress of polychlorinated biphenyls metabolites in the field of quality and safety of aquatic products,mainly including the qualitative and quantitative nalytical methods, toxicity effects,biotransformation mechanism of polychlorinated biphenyls,and summarized the research progress on the types of polychlorinated biphenyl metabolites congeners, residual levels and their effectsinfluence on the quality and safety of aquatic products globally.更多还原
