There is a need to develop screening level and cleanup criteria for nitroaromatic compounds at US Army Superfund sites. Using available methodologies, Water Quality Criteria (WQC) for aquatic organisms and toxicological benchmarks for terrestrial plants and wildlife were developed for eight nitroaromatic munitions compounds and/or their degradation products: 2,4,6-trinitroluene, 1,3,5-trinitrobenzene, 1,3-dinitrobenzene, 3,5-dinitroaniline, 2-amino-4, 6-dinitrotoluene, RDX, HMX, and tetryl. Depending on available data, acute and chronic WQC for aquatic species were developed based on US EPA Tier 1 or Tier 2 guidelines. Criteria for sediment-associated organisms were derived based on Equilibrium Partitioning. In the absence of criteria or guidance for effects on terrestrial wildlife, plants and soil processes, ecotoxicological benchmarks, i.e., NOAELs and LOECs for effects on these organisms were identified. Benchmarks for terrestrial wildlife species were derived from experimental data identifying toxicological endpoints for wildlife or laboratory species. NOAELs were based on endpoints of population growth and survival following oral exposures. These values were used as the basis for calculation of NOAELs or screening benchmarks for food and water intake for seven selected mammalian wildlife species: the short-tailed shrew, white footed mouse, meadow vole, cottontail rabbit, mink, red fox, and whitetail deer. Equivalent NOAELs were calculated by scaling the test data on the basis of differences in body weight. Benchmarks for terrestrial plants and soil invertebrates and heterotrophic processes were based on LOECs.
