Abstract : The research involved studies of the assimilation of polyaromatic hydrocarbons and polychlorinated biphenyl congeners by an amphipod and a chironomid. Assimilation efficiencies were calculated for these species using radioactively labeled benzoapyrene and hexachlorobiphenyl which was allowed to adsorb to sediment particles of various sizes. One conclusion of the research was that differential bioavailability of a chemical may not depend as much on the behavior of the organism as on the nature of the compound and its interaction with the sediment components.
