A Comparison of Microcosm and Bioassay Techniques for Estimating Ecological Effects from Open Ocean Disposal of Contaminated Dredged Sediments.
Abstract
The potential ecological impact of open ocean disposal of dredged material must be assessed on a site by site basis. A variety of research methods can be employed for this assessment. Static bioassays have been and continue to be the most common means for biologically evaluating the toxicity of dredged sediments. The validity of bioassay techniques in effectively assessing the potential ecological impact of ocean disposal of dredged materials is open to question. This report deals specifically with results of a study designed to assess the relative effectiveness of standard bioassays and multiple species microcosms in the evaluation of the suitability of dredged materials for open ocean disposal. Keywords: Norfolk Harbor and Channels; Sediment quality.
