| Abstract |
This project was designed to evaluate the current status of sediments in the UMR by: (1) measuring the concentrations of contaminants in sediments of the UMR, (2) evaluating the toxicity of sediments collected from the river, (3) determining the bioaccumulation of contaminants from UMR sediments using field-collected and laboratory exposured oligochaetes, and (4) determining the benthic community structure in fine-grain sediments within the river. Chapter 1 of this report describes whole-sediment toxicity tests which were conducted for 28 days with the amphipod Hyalella azteca. Chapter 2 describes the bioaccumulation of contaminants from sediments using field-collected oligochaetes and 28-day bioaccumulation studies conducted in the laboratory with the oligochaete Lumbriculus variegatus. Chapter 3 assesses the benthic community in all 24 C samples. |
