| Abstract: | In a preliminary survey, Crassostrea virginica from areas of the Corpus Christi Bay system of Texas show significant concentrations of Cd, Cu, Pb, and Zn in their tissues and shells; concentrations of these same metals in associated sediments are also high in certain areas of the bay system. Zn and Cd concentrations in tissue show a high negative correlation to each other, whereas Zn and Pb in tissue and shell show a high positive correlation to one another. Sediment contents of Pb and Zn best reflect tissue values of the heavy metals; sediment concentrations of Cd and Cu show a poor inverse correlation to tissue concentrations. Some possible factors influencing these correlations are suspended-sediment type, physiological changes, water quality, and Ca intake. |
