The toxicity of nitroglycerine to a wide variety of aquatic organisms representing several different trophic levels in aquatic ecosystems was studied. Results of static acute toxicity tests indicate that the acute LC50 values are greater than 3 mg1 RDX. There was an apparent lack of bioaccumulation in edible or nonedible tissues or organs in all species tested. Effects were observed on growth at 5.8 mg1 RDX during egg and fry studies, on survival at 4.9-6.3 mg1 during chronic exposure of fathead minnows, and on number of young produced per parthenogenetic female at concentrations equal to or greater than 4.8 mg1. Applying an application factor of 0.1 to the lower limit of observed acute toxicity values 3.6 mg1, 96-hour LC50 for bluegill at pH 6.0 a water quality criterion of 0.35 mg1 RDX is proposed. Author
