Polynuclear Aromatic Hydrocarbons and Toxicity of Sediments from the Elizabeth River, Hampton Roads, Virginia
Abstract
A series of environmental studies in the Port of Hampton Roads, Virginia indicate that sediments from certain areas of the Southern Branch of the Elizabeth River are quite toxic and are believed to be contaminated by a variety of pollutants. One group of pollutants that is of particular concern is a class of compounds known as polynuclear aromatic hydrocarbons (PNAH's). Preliminary surveys of the sediments in the most toxic regions of the Elizabeth River revealed that high concentrations of PNAH's (i.e. high ppm range) are found in the sediments. The high levels of these contaminants are of particular environmental concern because they are long-lived toxins and many are mutagenic and/or carcinogenic. The present study was designed to 'map' and characterize the distribution of PNAH's in the sediments of the major navigation channels of the Elizabeth River. Data from extensive biological chemical investigations of stations located throughout the main stem and Southern Branch of the Elizabeth River were analyzed by multivariate statistical techniques to characterize the major patterns of the sediment quality in the port. The results of the geographic characterization of chemical and biological effects patterns should provide valuable information to managers and regulators who must make policy decisions concerning issues such as which sediments are acceptable for ocean disposal.
