The blue mussel (Mytilus edulis) has been proposed for use as a sentinel organism to monitor the effects of marine pollution (Goldberg et al., 1978). Recently, there has been interest in quantifying histopathological changes in mussel tissues, as one indicator of pollution-induced stress. Cadmium is a common and toxic aquatic pollutant. Gill and digestive diverticula have been shown to be major sites of cadmium detoxification. In these same tissues, histopathological changes have been demonstrated after exposure to crude oil and to an oil dispersant. However, whether similar morphological changes are induced by heavy metals, such as cadmium, is not known. In this study, the authors have assessed the cellular effects of sublethal concentrations of cadmium on the gill and digestive diverticula of Mytilus.
