ABSTRACT
All organisms have strategies allowing them to cope with chemical stress, including exposure to toxic contaminants, and all are inevitably members of food webs, consisting of several interrelating food chains. Furthermore, as has been well exemplified in other chapters in this volume, many organisms can develop tolerance to contaminant exposure, whether by acclimation or by genetic adaptation. This chapter addresses the question of whether the acquisition of tolerance to a contaminant by an organism has any implications for the trophic transfer of that contaminant to animals higher up any food chain.
