Tidal Wetlands Of The Mattaponi River : Potential Responses Of The Vegetative Community To Increased Salinity As A Result Of Freshwater Withdrawal, Carl Hershner, Paul M. Booth, Laura R. Mitchell
Tidal Wetlands Of The Mattaponi River : Potential Responses Of The Vegetative Community To Increased Salinity As A Result Of Freshwater Withdrawal, Carl Hershner, Paul M. Booth, Laura R. Mitchell
Reports
The potential responses of wetland vegetation on the Mattaponi River to the proposed withdrawal of freshwater and the resulting alteration in salinity patterns were studied by comparing existing plant community distributions (which were surveyed in the summer of 1990) and historical vegetation distributions (which were evaluated through the use of aerial photography from 1953, 1971, and 1987) with estimated salinity patterns (developed from historical and adjusted freshwater inflows using a simulation model developed previously at the Virginia Institute of Marine Science).

Contaminant Accumulation In Hard And Soft Shell Blue Crabs From An Urban Subestuary, Robert F. Mothershead
Contaminant Accumulation In Hard And Soft Shell Blue Crabs From An Urban Subestuary, Robert F. Mothershead
Dissertations, Theses, and Masters Projects
Muscle and hepatopancreas of blue crabs (Callinectes sapidus), collected from the Elizabeth River, Virginia, contained residues of polycyclic aromatic hydrocarbon (PAHs}, polychlorinated biphenyls (PCBs) and organochlorine pesticides. Analytical procedures involved dichloromethane extraction of lyophilized tissue, followed by molecular size and polarity-based purification of the extract. capillary gas chromatography with flame ionization detection and electrolytic conductivity detection was used for quantitation and tentative identification of the xenobiotic compounds. Mass spectrometry was used for confirmation of these identities. Contaminant concentrations were greater in hepatopancreas than in muscle in crabs from every site examined. Hepatopancreas PAH burdens were as high as 11 mg/kg …
