Abstract

In this paper we report on studies undertaken to: (1) establish 1nercury levels in biota and sediments from the lower portion of Chesapeake Bay; (2) describe the pattern of metal distribution in oysters from 3 Virginia estuaries; and (3) determine if estuarine sediments can be used to detect the effects of man's activities on the environn1e nt. To date, mercury analyses of biota from the Bay area have sho\vn no levels in excess of FDA guidelines, nor have they indicated any influence of man's activities in the areas studies. Oysters have been shown to vary naturally in their body burdens of the heavy metals copper, cad1nium, and zinc- and techniques are suggested whereby unnatural heavy metal inputs can be identified. Sedi1nents from an industrialized river system have been shown to reflect the inputs from human activities.
