The toxicity of nitroglycerine to a wide variety of aquatic organisms representing several different trophic levels in aquatic ecosystems was studied. The results of static acute toxicity tests indicate that the nominal acute LC50 values are generally greater than 1 mg1 nitroglycerine. A pilot bioaccumulation study with 14C-nitroglycerine showed that there was no appreciable accumulation of 14C-nitroglycerine in the edible tissues of four fish species. The estimated application factor for fathead minnow over one complete life cycle is 0.01-0.02 and 0.03-0.07 for eggs and fry of the fathead minnow and channel catfish, 0.2-0.4 for daphnids and 0.3-0.6 for midges. Applying the lower limit of all estimates of the application factor 0.03 to the lower limit of the observed acute toxicity values for freshwater organisms 1.28 mg1, 96-hour LC50 for bluegill at pH 6.0, we propose a water quality criterion of 0.01 mg1 nitroglycerine.
