Since trace metals such as mercury, cadmium, copper, and zinc can be released to the marine environment as a result of the operation of energy technologies, their potential effects on marine organisms need to be understood. Marine organisms have the capability to respond to metal exposure through acclimatization or adaptation to altered conditions. Mechanisms which may be involved in conferring such capabilities have also been identified. This research project investigated one of these mechanisms, the low molecular weight, metal-building protein MT, in relation to metal toxicity and acclimatization/adaptation. Specific topics included purification and characterization of molluscan MTs; examination of the kinetics of induction of these proteins in response to the above metals; the cellular disposition of metals in relation to induction; and metal-toxicity in relation to induction of metal-binding proteins. Studies were conducted on the bay mussel Mytilus edulis and the American oyster Crassostrea virginica. These efforts were planned to contribute to a better understanding of MTs and their relationship to toxic and adaptive responses in commercially- and ecologically-important marine animals.
