Projected Hg Dietary Exposure Of 3 Bird Species Nesting On A Contaminated Floodplain (South River, Virginia, Usa), Jc Wang, Mc Newman Jan 2013

Projected Hg Dietary Exposure Of 3 Bird Species Nesting On A Contaminated Floodplain (South River, Virginia, Usa), Jc Wang, Mc Newman

VIMS Articles

Dietary Hg exposure was modeled for Carolina wren (Thryothorus ludovicianus), Eastern song sparrow (Melospiza melodia), and Eastern screech owl (Otus asio) nesting on the contaminated South River floodplain (Virginia, USA). Parameterization of Monte-Carlo models required formal expert elicitation to define bird body weight and feeding ecology characteristics because specific information was either unavailable in the published literature or too difficult to collect reliably by field survey. Mercury concentrations and weights for candidate food items were obtained directly by field survey. Simulations predicted the probability that an adult bird during breeding season would ingest specific amounts of Hg during daily foraging …


Estuarine Blue Infrastructure: Final Priority Conservation Areas For Chesapeake Bay And Its Tidal Tributaries And Back Bay – Version 2.0 (Revised 09/2010), Center For Coastal Resources Management, Virginia Institute Of Marine Science Sep 2010

Estuarine Blue Infrastructure: Final Priority Conservation Areas For Chesapeake Bay And Its Tidal Tributaries And Back Bay – Version 2.0 (Revised 09/2010), Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

This project is an extension of earlier efforts within the coastal zone of Virginia to build a platform for enhanced Blue and Green Infrastructure planning. This project is motivated by an interest in extending statewide conservation efforts into estuarine systems and recognition that land use decisions on the upland effect water quality and habitat health in the receiving waters. The project in its entirety has been accomplished in distinct parts. Part one develops a Cumulative Resource Assessment to evaluate the distribution of aquatic natural resources within waters of Virginia’s Chesapeake Bay waters, Back Bay of Virginia Beach, Virginia, and the …

Liver Carcinogenesis In A Non-Migratory Fish: The Association With Polycyclic Aromatic Hydrocarbon Exposure, Wolfgang K. Vogelbein, M. A. Unger Jan 2006

Liver Carcinogenesis In A Non-Migratory Fish: The Association With Polycyclic Aromatic Hydrocarbon Exposure, Wolfgang K. Vogelbein, M. A. Unger

VIMS Articles

Field and laboratory studies indicate a strong positive association between exposure to chemical pollutants in aquatic environments and development of neoplasia in fishes. This brief communication reviews some of the more important North American and European studies that have been conducted on this relationship. We then review work conducted on a small nonmigratory estuarine cyprinodontid teleost fish, the mummichog (Fundulus heteroclitus) in the industrialized Elizabeth River, Virginia USA. Histopathological surveys of mummichogs from variously degraded habitats indicate an association between PAH exposure and development of neoplasia. We have observed non-neoplastic lesions, preneoplasms and hepatic, biliary, exocrine pancreatic and vascular neoplasms …

Determination Of Marina Buffer Zones Using Simple Mixing And Transport Models : A Report To The Virginia State Dept. Of Health, Bureau Of Shellfish Sanitation As Part Of The Chesapeake Bay Initiatives Marine Pollution Abatement Initiative, John M. Hamrick, Bruce J. Neilson May 1989

Determination Of Marina Buffer Zones Using Simple Mixing And Transport Models : A Report To The Virginia State Dept. Of Health, Bureau Of Shellfish Sanitation As Part Of The Chesapeake Bay Initiatives Marine Pollution Abatement Initiative, John M. Hamrick, Bruce J. Neilson

Reports

This report describes the rationale, development and application of simple mixing and transport models for the determination of marina buffer zones and buffer zones for other point source discharges. Included in the report are two computer programs for implementation of the most general two dimensional transport model.


Organic Compounds In Surface Sediments And Oyster Tissues From The Chesapeake Bay, R. H. Bieri, P. O. Dufur, R. J. Huggett, W. Macintyre, P. Shou, C. L. Smith, C. W. Su Jul 1981

Organic Compounds In Surface Sediments And Oyster Tissues From The Chesapeake Bay, R. H. Bieri, P. O. Dufur, R. J. Huggett, W. Macintyre, P. Shou, C. L. Smith, C. W. Su

Reports

This report contains three parts. In Part I, the methodology to extract and analyze sediment and oyster tissue samples from the Chesapeake Bay is described in detail. Remaining problems are clearly identified. Part II contains the results and their discussion. Part III contains a number of appendices with detailed data. For those readers interested in still more detail, the complete bank of processed data is on computer tapes at this institute and at the Environmental Protection Agency-Chesapeake Bay Program office at Annapolis, Maryland. Also included in Part III we give the results of volatile halogenated organic compounds determined in water …
