| Abstract: | - 1.1. First-generation laboratory animals of three populations of the isopod Porcellio scaber, collected from a reference wood, a zinc smelter area and a lead mine site, were compared with respect to effects of Cd.
- 2.2. All populations reacted differently to Cd-contaminated food: increased Cd concentrations in the food resulted in decreased consumption and growth for the reference isopods; mine isopods were not affected by Cd and for the smelter animals Cd stimulated growth at an intermediate concentration.
- 3.3. Since Cd concentrations in the isopod did not differ between populations, adaptation is probably based on an increased detoxification capacity.
- 4.4. The assimilation of Cd did not affect the Cu or Zn content of the isopods although the adapted isopods regulated their Cu content on a lower level than reference isopods.
