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 ...


The Present State Of Organic Xenobiotics In The Chesapeake Bay - A Synthesis Paper, R. J. Huggett, R. H. Bieri, P. O. Defur, W. G. Macintyre, P. Shou, C. L. Smith, C. W. Su Jun 1981

The Present State Of Organic Xenobiotics In The Chesapeake Bay - A Synthesis Paper, R. J. Huggett, R. H. Bieri, P. O. Defur, W. G. Macintyre, P. Shou, C. L. Smith, C. W. Su

Reports

This manuscript discusses the results of the first two and one half years of a three-year study designed to determine the present state of xenobiotic compounds in the Chesapeake Bay. It shows that polynuclear aromatic hydrocarbons are the most frequently encountered compounds and are the most abundant. Concentrations are highest in the Northern Bay with several sources implicated. During this study an apparent dumping of the pesticide, DDT, occurred. Either the quantity disposed of was small enough or the assimulation capacity was large enough that no adverse effects were noted. The detection by us of 6-phenyldodecane in bottom sediments of ...


Study To Investigate Source And Transport Route Of Marine Organisms (Hydroids And Bryozoans) In Hampton Roads And Current Velocity Profiles Of The Pier 12 Area, Naval Station, Norfolk, Virginia, Robert J. Diaz, Evon P. Ruzecki Jan 1981

Study To Investigate Source And Transport Route Of Marine Organisms (Hydroids And Bryozoans) In Hampton Roads And Current Velocity Profiles Of The Pier 12 Area, Naval Station, Norfolk, Virginia, Robert J. Diaz, Evon P. Ruzecki

Reports

Entrainment of the hydroid (Sertularia argentea) and the fleshly bryozoan (Alcyonidium verrilli) in the sea suction of deep draft naval vessels (carriers) in the area of the Norfolk Naval station has been a recurring problem since the early 60's. These fouling organisms (the term fouling is used in this report to indicate clogging of hull bottom intake grates and cooling system condenser tube sheets and not the growth of organisms on any part of the vessel) are winter species, growing only in the fall and winter and not the summer. Unfortunately they are also the most abundant and widely ...
