Terrestrial isopods (woodlice) have been the subject of numerous publications on the dynamics of metals in terrestrial invertebrates. They are of particular interest due to the ability of the hepatopancreas of woodlice to accumulate zinc, cadmium, lead and copper to very high concentrations. In a recent study, Hopkin showed that O. asellus from a zinc-contaminated site was able to excrete this metal at a faster rate than P. scaber when both species were fed an uncontaminated diet. In contrast, O. asellus had a greater affinity for cadmium and retained this metal to a much greater extent than P. scaber. In this paper, the rates of assimilation and excretion of two of these metals have been quantified by feeding O. asellus and P. scaber on leaves contaminated with radioactive isotopes of zinc and cadmium.
