Heavy Metal Concentrations In The Clam Rangia Cuneata From The Rappahannock And James Rivers, Robert Emile Croonenberghs
Heavy Metal Concentrations In The Clam Rangia Cuneata From The Rappahannock And James Rivers, Robert Emile Croonenberghs
Dissertations, Theses, and Masters Projects
This project investigated the feasibility of using the brackish water clam Rangia cuneata as a heavy metal pollution indicator, and further investigated the state of heavy metal pollution in the James River. Rangia cuneata were sampled in the fall of 1972 from the Rappahannock and James Rivers , and meats were analyzed by atomic absorption spectrophotometry for wet weight concentrations of copper, zinc, cadmium and lead. Levels of copper and zinc in Rangia cuneata were shown to be unaffected by clam size, spawning differences, salinity or distance upriver, and substrate grain size. Heavy metal concentrations in the oxidized channel sediments, …

Benthic Infaunal Community Formation In Dredged Areas In Hampton Roads, Virginia, Thomas Karl Duncan
Dissertations, Theses, and Masters Projects
The macrobenthic fauna in three dredged areas in Hampton Roads, Virginia was sampled for 14 months. Repopulation occurred very rapidly after the cessation of dredging, but the dominant species were generally not those previously recorded as mud-bottom dominants in the Hampton Roads area. The faunal changes through time somewhat agreed with those reported in classical successional sequences. This dissertation is from the Joint Program Degree from the College of William & Mary and University of Virginia and awarded by the University of Virginia.
