- 摘要：在稳态模型的基础上，研究了有机污染物在多介质环境的动态模型，并针对单甲脒、单甲脒盐酸盐、DDT和DMP等4种有机污染物作了计算。结果表明，这类模型对于研究有机污染物在多介质环境中随时间变化的行为是有效的。
- Abstract：On the basis of steady state model, a seven compartments (water, air, sediment, fish, and root, stem and leaf of plant) dynamic model of N—(2, 4 dimethylphenyl)—N'—methyl formamidine (NAD), N—(2, 4 dimethylphenyl)—N'—methyl formamidine hydrochloride (NADH), dimethyl phthalate ester (DMP) and DDT in multimedia environment was studied using fugacity approach. The results show that various compounds in the same medium has different change rate of concentration, such as the order of concentration change rate in sediment is DMP>NADH>NAD>DDT. The sensitivity analysis shows that the sensitivity of chemicals concentration in environmental medium to input parameter uncertainties is different with physical and chemical properties and time.
