Abstract : This note provides initial Information on the format and potential application of a computerized database in conducting certain types of literature searches. The ultimate goal of this task is to provide Corps elements with numerical as well as descriptive guidance so that they can relate contaminant tissue residues to biological effects in aquatic organisms in a more accurate, consistent, and technically defensible fashion. Over the last 10 years, only a small number of sediments evaluated in regulatory testing programs have been found to be acutely toxic. Consequently, decisionmakers have relied less on toxicity and more heavily on bioaccumulation information. Unfortunately, there is little generally accepted interpretive guidance regarding the biological importance of bioaccumulation in aquatic organisms (Peddicord and Hansen 1983). In an effort to provide some initial guidance In this area, an assessment of the literature was conducted under the Long-Term Effects of Dredging Operations (LEDO) Program in which the association between bioaccumulation and biological effects in aquatic organisms was examined (Dillon 1984). pg1.
