We investigated individual toxicities of 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) to the potworm Enchytraeus crypticus using the Enchytraeid Reproduction Test (ISO 16387:2004). Studies were designed to identify and characterize the predominant soil physicochemical parameters that affect the acute (mortality) and chronic (reproduction) toxicities of TNT or RDX to E. crypticus, and to generate ecotoxicological benchmarks for developing the ecological soil screening levels (Eco-SSLs) for risk assessments of contaminated soils.

Ecological Soil Screening Levels (Eco-SSL) are those screening concentrations of chemicals in soil that present an acceptable risk to ecological receptors. We investigated the ecotoxicity of TNT to the plant species alfalfa (Medicago sativa L.), Japanese millet (Echinochloa crusgalli L. (Beauv.)), and perennial ryegrass (Lolium perenne L.) in five natural soils: Sassafras sandy loam (SSL), Teller sandy loam (TSL), Richfield clay loam (RCL), Kirkland clay loam (KCL), and Webster clay ...
