摘　　要：借助环境模型模拟污染物在多介质间的迁移、归趋行为和生物积累放大,既是生态和健康风险的评估基础,又是研究污染物环境过程的一种重要的方法和手段。利用生物积累模型研究持久性有机污染物(POPs)在食物链中的生物富集和生物积累放大对于生态及健康风险评价具有重要意义。重点介绍了国内外关于POPs在陆生食物链中的各类生物积累模型及应用,包括原理、模型的特点和优势及不足之处,并对模型的改进提出了相应的建议。基础环境参数不足、实验数据缺乏和物种特异性是制约此类模型发展的主要原因。With the aid of environmental models,transfer,fate,bioaccumulation and biomagnification of contaminants in a multi-compartment environment was simulated,which is not only a basis for evaluating ecological and health risks of persistent organic pollutants（ POPs） in food chain,but also an important approach to and means of studying environmental processes of the pollutants. It is of great significance to use bio-accumulation models in studying bioaccumulation and biomagnification of POPs in food chain to the evaluation of ecological and health risks of the POPs. A review is presented with emphasis on various bioaccumulation models available at home and abroad to simulate POPs bioaccumulation and biomagnification in the terrestrial food- chain,including principles,features,merits and shortcomings of the models and some case studies of their applications. Moreover,modifications of the models were recommended. Obviously the lack of basic environment parameters,shortage of experimental data,and plant species peculiarities are the major causes hindering development of this kind of models.
