ORGANIC COMPOUNDS IN SURFACE SEDIMENTS AND OYSTER TISSUES FROM THE CHESAPEAKE BAY. APPENDICES
Bieri, R., P. DeFur, R. Huggett, W. MacIntyre, AND P. Shou. ORGANIC COMPOUNDS IN SURFACE SEDIMENTS AND OYSTER TISSUES FROM THE CHESAPEAKE BAY. APPENDICES. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/3-83/018B.
Detailed in the first part of this report is a development and discussion of the methodology used to extract and analyze sediment and oyster tissue samples from Chesapeake Bay for organic compounds. The method includes extraction, fractionation, and subsequent analysis using glass capillary gas chromotography and glass capillary gas chromotography - mass spectrometry. An extensive list of the mass spectral data and related information is contained in the appendices. The complete bank of processed data is also available on computer tapes at the Virginia Institute of Marine Science and at the Environmental Protection Agency's Chesapeake Bay Program. Analyses clearly show that unsubstituted polynuclear aromatic hydrocarbons are the most prominent toxic pollutants in the Bay. The application of two different search routines, one concentrating on compounds at levels greater than 50 ppb and the other on temporal changes, allows a quick determination of where problem areas may exist and where additional investigation may be indicated.
