Abstract
A study of the effects of Cd+2 has been carried out on two crustacean isopod species (Asellus aquaticus L. and Proasellus coxalis Dollf.). ST comparisons indicated sensitivity differences in the two species and respectively among females, males and juveniles. Juveniles, born from parents bred in sublethal Cd concentrations, had greater sensitivity than their parents. Water hardness was ineffective on Cd tolerance. The importance of determining the toxicity of a pollutant on different stages of the life cycle and on subsequent generations in evaluating the poisoning effects on an ecosystem is discussed.Keywords
