Includes bibliographical references. "A fugacity model that was developed to assess the chemical fate of organic chemicals in regions of Canada has been incorporated into the RAISON (Regional Analysis by Intelligent Systems ON a microcomputer) expert system and has been modified and applied to ecodistricts of southern Ontario, Canada. The model is used to estimate a selected chemical’s distribution between four bulk compartments (air, water, soil, and sediment) and 4 subcompartments (groundwater, coastal water, plants and animals). Polychlorinated biphenyls (PCB’s), mirex, dieldrin, and hexachlorobenzene (HCB) were the chemicals considered in the application of the modelling system. Steady state concentrations predicted by the model were compared with available measured data for the ecodistricts. Considering the large degree, of lumping required for ecodistrict parameters, the model predicts concentrations within the compartments that are reasonable estimates, especially considering the fact that concentrations between the compartments vary over as much as 10 orders of magnitude"--Abstract. gccst Pollutants gccst Chemistry gccst Ecology gccst Models Wong, Isaac Wai Soon, 1957- author.
