TL;DR: In this article, the authors describe protocols for testing freshwater organisms in the laboratory to evaluate the toxicity or bioaccumulation of contaminants associated with whole sediments, including the amphipod Hyalella azteca and midge Chironomus tentans.

TL;DR: This paper reviews recent developments in methods for evaluating the toxicity and bioaccumulation of contaminants associated with freshwater sediments and summarizes example case studies demonstrating the application of these methods.

TL;DR: Manganese toxicity should be considered when assessing solutions with concentrations approaching these levels, and tolerance of C. dubia to Mn was not significantly different between moderately hard and hard waters, but was significantly lower in soft water.

TL;DR: Results showed standard 10-d whole-sediment toxicity test methods for the amphipod Hyalella azteca and the midge Chironomus tentans to have relatively low variance and acceptable levels of precision in interlaboratory comparisons.

TL;DR: Drainage from dredge-disposal areas may be impacting habitat quality in the river, and fish and wildlife that feed and nest in the disposal areas on the lower Savannah River may be at risk from metal contamination.
