Abstract: Updated methods for assessing the sediment toxicity of insensitive munitions (IM) compounds using freshwater benthic invertebrates are recommended by United States Army Corps of Engineers (USACE). A solvent-free method is used to spike sediment that is considered uncontaminated and suitable for use in whole sediment toxicity tests with IM formulations or their single constituents. Selection of sediment with low organic carbon and ammonia content is recommended. For each treatment, carrier solvent containing the appropriate mass of IM formulations, or one of their single constituents, is transferred into an open top jar and rolled on a horizontal rolling mill while the solvent is removed by evaporation. This leaves a coating of compound on the inner jar surface. Wet sediment is added to the jar which is then closed tightly. The sealed jar is rolled to abrade the compound from the jar walls and mix with the sediment.
