THE ESTABLISHMENT OF STABLE EQUILIBRIUM MODEL OF MONOCARBOXOLDEHYDE AND OTHER ORGANIC POLLUTANTS IN MULTIMEDIA ENVIRONMENT
单甲脒等有机污染物多介质环境的稳态平衡模型构建

he physico-chemical paramenters(Kow,eveporation pressure,water solubility,Koc and BCF)of monocarboxoldehyde and other 19 organic pollutants were estimated and fugacityapproach model of multimedia environment at stable equilibrium for pond and agriculturalfield ecosystems was made.The primary reaults show that the model prediction for concen-tration distribution of organic pollutants in multimedia environment at stable equilibrium condition is feasible.For hydrophobic organic chemicals,the concentration in soil or sediment>water>air.For hydropholic organic chemicals,the concentration in water>soil or sedi-ment>air.In plants,the concentration of both types of chemicals in leaf>roots>stem.Infish,the contents of all involied chemicals are not too different.
