有机污染物多介质环境的稳态非平衡模型

NON-EQUILIBRIUM STEADY MODEL FOR FATE OF ORGANICS IN THE MULTIMEDIA ENVIRONMENT

在稳态平衡模型的基础上，研究了有机污染物在多介质环境的稳态非平衡模型，并针对ＤＤＴ、１，２，４－ＴＣＢ、ＨＣＢ、ＰＣＢ和ＤＭＰ５种化合物进行了计算。结果表明，该模型只须通过污染物在水中的浓度以及该化合物的各种物理化学性质和环境参数就可计算环境各相中污染物的浓度、逸度和质量分布，从而预测污染物在多介质环境中的归趋。

Non-equilibrium steady model for organic pollutants in multimedia environment was de-rived from an equilibrium model.To predict the concentration,fugacity,and mass distribu-tion of a chemical in a multimedia environment,only inputs required for the modelling are concentrations of the chemical in water and air and its physical and chemical parameters.The fate of five chemical of DDT,1,2,4-TCB,HCB,PCB,and DMP were modelled.
