Abstract : Relatively little is known on insensitive munitions compounds, 2,4-dinitroanisole (DNAN) and 3-nitro-1,2,4-triazol-5-one (NTO), perform in the environment. The objectives of this study were to evaluate the interaction of abiotic and biotic factors contributing to the attenuation of IMCs in the soil leading to the formation of environmentally safe end-points. Anaerobic conditions favored the biological and/or chemical reduction of the nitro groups leading to the formation of amines intermediates. The amines retained toxicity thus futher conversion was required. The amines formed from DNAN eventually became covalently incorporated into soil organic matter. The amine from NTO became mineralized by soil bacteria or manganese dioxide to carbon dioxide and inorganic nitrogen.
