A Data Base Assessment of Environmental Fate Aspects of Nitroguanidine
Abstract
This report is a current assessment of the data base available for nitroguanidine, a component of US Army triple-base propellant mixtures. Nitroguanidine is scheduled for production at Sunflower Army Ammunition Plant, DeSoto, KS. Sufficient gaps exist in the data available on the environmental fate and aquatic and mammalian toxicity of nitroguanidine to warrant further studies. Data describing physical transport of nitroguanidine are totally lacking. Although solubility of nitroguanidine is well known, no experimental information is available for the octanol-water partition coefficient (estimated K02 = 2.7) and bioconcentration in aquatic species. Hydrolysis rates of nitroguanidine in natural water are not known. Photolysis in natural waters where humics and suspended solids are present must be measured. Other chemical transformations, including oxidation/reduction, will have to be screened and measured. Nitroguanidine is capable of being anaerobically biodegraded; however, whether or not microorganisms indigenous to the creeks receiving nitroguanidine effluents can also degrade the compound, and if so, at what rate, needs to be determined. It is not known if water plants will take up nitroguanidine. More data are required to precisely assess the hazard of nitroguanidine to mammalian and aquatic species.
