Estimate Of The Total Weight Of Kepone In The Major Components Of The Molluscan Fauna Of The James River, Virginia, Dexter S. Haven, Reinaldo Morales-Alamo Jan 1980

Estimate Of The Total Weight Of Kepone In The Major Components Of The Molluscan Fauna Of The James River, Virginia, Dexter S. Haven, Reinaldo Morales-Alamo

Reports

Contamination of the James River in Virgin ia with the pesticide Kepone has resulted in its accumulation in the tissues of the fauna inhabiting the river. Most of the Kepone available to the biota in the river is associated with sediment s (Schneider and Dawson, 1978) and Haven and Morales-Alamo (1979) have shown that oysters and other bivalve molluscs accumulate Kepone in their tissues when exposed to the pesticide associated with sediments in suspension. It is of interest to compare the quantities of Kepone bound in James River sediments with the quantities bound in the molluscan fauna of the river.

Heavy Metal Inventory Of Suspended Sediment And Fluid Mud In Chesapeake Bay, Richard Harris, Maynard M. Nichols, Galen Thompson, John Banacki, George Vadas

Reports

Heavy metals have been found associated with suspended material, sediments and fluid mud in the Chesapeake Bay. A series of field observations were made along the Bay axis to determine the metal concentrations and their distributions at relatively high and at average river inflow between March 27-April 9 and May 2-10, 1979.

Metal concentrations in suspended material per unit volume of water relate to the concentrations of suspended material. They are higher in the zone of the turbidity maximum than landward in river water or seaward in estuarine water. Thus, metals associated with suspended material tend to accumulate in the …

A Water Quality Modeling Study Of Lynnhaven Bay, Virginia, A. Y. Kuo, P. V. Hyer Dec 1979

A Water Quality Modeling Study Of Lynnhaven Bay, Virginia, A. Y. Kuo, P. V. Hyer

Reports

The City of Virginia Beach has proposed channel dredging in the Eastern Branch of the Lynnhaven Bay for the purposes of recreations and drainage improvement. It is therefore necessary to examine the possible environmental results of such a project. This environmental assessment is complicated by another proposal to modify the Lynnhaven system. The U.S. Army Corps of Engineers has proposed adding a second canal leading to the Eastern Branch, in order to reduce flood damage. This canal project would affect the Lynnhaven system by increasing nonpoint sources of pollution and by increasing the tidal prism. The water quality consequences of …

A Description Of The Commercial Marine Fisheries Of Virginia, James Zaborski

Reports

The magnitude and valtte of the fisheries of Virginia are significant. Expansion of some fisheries since 1977 in conjunctio~ with rising prices for fishery products in general has increased the importance of this industry to the Commonwealth. Virginia's fisheries are varied, some segments of the industry such as the oyster fishery have been in existence since colonial days; others, such as the surf clam fishery, are relatively new. The size and composition of the different industries also differ widely. The menhaden fishery exempli~ies what might be termed corporate fishing while the blue crab fishery is conducted by numerous individual owner-operators. …
