Abstract Laboratory systems need to incorporate complex processes, such as bioturbation and sorption by plants, to predict the fate of a toxicant in an aquatic environment. Two experiments were designed to study the influence of lugworms (Arenicola cristata) and seagrass (Thalassia testudinum) on Kepone distribution in sediment-water microcosms. Radiolabeled Kepone was introduced into these continuous flow systems, and the dissolved and sorbed concentrations were quantified. The activities of lugworms decreased the Kepone concentration in the water and increased the concentration sorbed to sediment. Seagrasses slightly affected toxicant distribution by delaying the dissolved concentration equilibrium. The fate of Kepone was influenced by more complex processes than can be considered in simple laboratory tests. Such processes must be studied in microcosms to adequately predict toxicant distribution in natural ecosystems.
