Abstract
Acute toxicity tests were carried out with four metals on the intertid al gastropod Morula granulata (Duclos). The resulting 96 h LC50 values showed that copper was the most toxic metal, with mercury being more toxic than cadmium and zinc. LC50 values being 0.37, 0.49, 2.06, 4.16 ppm for copper, mercury, cadmium and zinc respectively. The results we re in agreement with those for other gastropods given by other workers . The safe concentrations for all these metals were also calculated.
