@@1. Introduction Disposal of unwanted weapon systems due to demilitarization causes pollution problems at military complexes and the major contaminant at many military sites is 2,4,6-trinitrotoluene (TNT). TNT in common with most explosive compounds, is toxic, mutagenic and highly energetic. It has been shown to be toxic to fish, algae, microorganisms and threatens human health.
