In the present study, the interactive effects of Al3+, Ca++ and pH on adult Asellus aquaticus (L.) were investigated. These animals were selected because of their possible usefulness as an indicator species. Results confirmed that there is a higher mortality and death occurs more rapidly at lower pH values. The effects of aluminium on longevity in A. aquaticus were investigated at two temperatures; generally, they survived less well at 18°C than at 11°C. Al3+ had a noticeable effect on oxygen consumption in test specimens and acclimation to Al3+ solutions proved to have considerable influence on this. The range of concentrations of Ca++ provided a protective effect against aluminium toxicity.
