Water Quality Criteria for 2,4-Dinitrotoluene and 2,6-Dinitrotoluene.
Abstract
Data available for calculating a Final Acute Value (FAV) for 2,4-DNT do not meet all the requirements specified by the USEPA guidelines. However, since the data generated by these toxicity test are uniform in their assessment of the degree of toxicity of 2,4-DNT, a freshwater FAV of 11.02 mg/L 2,4-DNT was estimated. Although insufficient data are available to calculate a criterion as described in the USEPA guidelines, using the FAV and an acute/chronic ratio of 54.3, an interim Criterion Maximum Concentration (CMC) of 5.5 mg/L 2,4-DNT and a Criterion Continuous Concentration (CCC) of 0.20 mg/L 2,4-DNT are suggested. At present, no CMC or CCC can be calculated for 2,6-DNT; however, based on only a few studies, it appears that the 2,6- isomer is approximately twice as toxic to aquatic organisms as the 2,4- isomer.
