Abstract
Samples of the American (eastern) oyster, Crassostrea virginica, were collected from 11 locations along the South Carolina coast. There were wide variations in iron concentrations, although these were not obviously related to geographical location. Copper concentrations were apparently indicative of the environment, especially in the Wando River, an estuary near Charleston, South Carolina. Oysters from the upper Wando contained 3–20 times as much copper as oysters from other sites.
