Application of Carbon and Nitrogen Stable Isotope Analysis to Evaluate Biotic and Abiotic Degradation of DNAN and NTO
Abstract
The key objectives of this project were (1) to develop and validate compound-specific stable isotope analysis (CSIA) methods for carbon and nitrogen in the insensitive munitions constituents 2, 4-dinitroanisole (DNAN) and 3-nitro-1, 2, 4-triazol-5-one (NTO) and (2) to quantify kinetic isotope effects in carbon and nitrogen during the biotic and abiotic degradation of these compounds. These objectives were accomplished. The resulting isotopic enrichment parameters provide insights into natural and engineered degradation pathways and new diagnostic measurement tools that will allow the extent of in situ degradation to be quantified in soils and natural waters on ranges and other contaminated sites. This research was responsive to ERSON-17-03 as it provides new methods to "develop an improved understanding of the fate and effects of the components DNAN and NTO that are used in the insensitive munitions formulations." This project also provides a valuable means by which to assess the necessity and effectiveness of in situ enhancement of biotic and/or abiotic degradation strategies for these insensitive munitions compounds.
