摘　　要：研究持久性有机污染物(Persistent organic pollutants,POPs)在食物链中的积累与放大是进行环境风险评估和有效污染控制的生态学基础.本文综述了POPs的基本特征,POPs在食物链中的生物积累与放大的机制、影响因素以及POPs在食物链中积累与放大的模型等的研究进展.国外学者对POPs在水生食物链的积累与放大方面研究较多,并提出了较为完善的预测模型,而有关POPs在陆生食物链中的生物积累与放大的研究报道较少.大部分学者并未对完整食物链进行过系统而完整的研究.与国外相比,国内学者对POPs在水生陆生食物链中的生物积累、生物放大和预测模型探讨较少.目前POPs对环境和人体健康危害越来越严重,开展对POPs在食物链中积累、放大及相关预测模型更深入更完整的研究,已成为当前生态学和环境科学研究的重点课题和前沿领域.The study on risk assessment and effective pollution control is ecologically important to understand the bioaccumulation and biomagnification of persistent organic pollutants （POPs） in both aquatic and terrestrial food chains. This paper reviews the characters of POPs, the mechanism, impact factors and models of bioaccumulation and biomagnification of POPs in the food chain. Many researchers in foreign countries studied the bioaccumulation and biomagnification of POPs in aquatic food chain. However, only a few researchers focused their studies on terrestrial food chain, and even fewer researchers did on the both food chains. However, there is little information on the bioaccumulation and biomagnification of POPs in food chain in China. Therefore, it is necessary to study the bioaccumulation and biomagnification, as well as the related treatment models of POPs in food chain when the POPs are now becominu more and more harmful to the environment and human health.
