Explosive compounds have been released into the environment during manufacturing, handling, and usage procedures. These compounds have been found to persist in the environment and potentially promote detrimental biological effects. The lack of research on bioaccumulation and bioconcentration and especially dietary transfer on aquatic life has resulted in challenges in assessing ecological risks...

Abstract Soil and water get polluted with hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) during its manufacturing, storage use for civil military purposes. RDX has toxic effects on living non-living environment is a recalcitrant compound. Therefore, the remediation of this compound necessary. Microbial degradation can be suitable sustainable option to reduce deleterious impact environment. optim...

Hexahydro-1,3,5-trinitro-1,3,5,-triazine (RDX) is a cyclic nitramine explosive that is a major component in many military high-explosive formulations. In this study, we developed a real-time TaqMan polymerase chain reaction (PCR) that targets the xplA functional gene involved in the breakdown/transformation of RDX. The xplA gene, described previously [Seth-Smith, H.M., Rosser, S.J., Basran, A.,...

BACKGROUND Although microRNAs (miRNAs) have been found to play an important role in many biological and metabolic processes, their functions in animal response to environmental toxicant exposure are largely unknown. OBJECTIVES We used hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), a common environmental contaminant, as a toxicant stressor to investigate toxicant-induced changes in miRNA expre...

Molecular dynamics simulations were carried out to study the effects of interface interactions between a crystalline structure and a plastic bonded explosive (PBX) system. In this work, the hydroxyl-terminated polybutadiene (HTPB) represents the polymer, isophorone diisocyanate (IPDI) is the diisocyanate and dioctyl adipate (DOA) is the plasticizer. Two different crystal high explosives compone...

Perchlorate, an oxidizer routinely used in solid rocket motors, is easily washed out of old motors. The washout operation, however, leads to wastewater containing perchlorate. Royal Demolition Explosive (RDX), a major component of military high explosives, is transferred to Army industrial wastewaters during assembly of new munitions and during demilitarization of old munitions. New high explos...

For reliable detection of explosives, a combination of methods integrated within a single measurement platform may increase detection performance. However, the efficient field testing of such measurement platforms requires the use of inexplosive simulants that are detectable by a wide range of methods. Physical parameters such as simulant density, elemental composition and crystalline structure...

Contamination of soil, sediments and groundwater by organic pollutants is a current problem that threatens both human and environmental health. The use of microorganisms to remediate pollution (bioremediation) is a viable option for site remediation. However, limited knowledge exists concerning the key microorganisms involved in the degradation of many pollutants. In this study, specific aspect...

Investigating the thermal decomposition characteristics and mechanisms of nano- submicron-aluminized 1,3,5-trinitro-1,3,5-triazine (RDX) is essential to optimize formulations improve combustion/detonation efficiencies. However, no research has focused on microscopic scale a single aluminized RDX particle. We demonstrate an all-fiber probing method for violent nano-aluminized micron-RDX particle...

Detecting hidden explosive devices in war zones and transportation hubs is a pressing concern. Current efforts have focused on sensing three commonly used powerful explosives: 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitro-1,3,5-triazinane (RDX) and pentaerythritol tetranitrate (PETN) (Chart 1). The need for ultratrace detection of these low-volatility compounds has resulted in an intense interest...
