| Abstract: | The basic concepts,model principle,characterization and researching region of the multimedia environmentaquivalence model have been approximately discussed in the paper,and their evolution process,diffusion mechanism andinterphase behavior to a variety of heavy metal pollutions mainly the mercury and mercurates in water environments,espe-cially in Three-Gorges valley could been fairly well described by the aquivalence model which has been modified on modelparameters,correlation conditions and algorithm in order to fit to more effectively sensitivity analysis of affected factors andinterphase transports rates in various of static state or pseudo flowing water system.The chemical fate of heavy metal com-pounds in water environmental system including Three-Gorges valley could be quantitative simulated through our modifiedcomputer program for multimedia environment chemical pollution behavior. |
