Mercury in Sediments from Three Virginia Estuaries

Abstract
A survey of mercury levels in sediments (<63 μ) from Virginia's three main estuaries was conducted. Results indicated that the mercury was associated with the organic fraction of the bottom material. Statistical analyses showed no differences (5% significance level) within rivers with respect to distance from the mouth or between rivers. Comparison of the estuarine levels to those of oceanic and freshwater sediments show the oceanic to be more closely related to the estuarine with respect to mercury concentrations.
