The distribution of radiolabeled Kepone was studied in a continuous flow sediment-water microcosm to predict the fate of the compound in an aquatic environment. The sediment was fractionated into layers and the sorbed Kepone concentrations were measured to determine toxicant penetration into the sediment. The data were used to test the validity of using a mathematical model based on independent studies of the processes affecting Kepone to predict the distribution of the toxicant in the microcosm sediment and water. The model accurately described the observed Kepone distribution. Microcosms, by simulating the complexity of natural environments, provided a useful tool for evaluating the accuracy of mathematical predictions concerning the distribution of a toxicant in aquatic systems.
