At one military installation in the eastern US, surface and underlying soils have significant HE contamination as a result of more than 50 years of live-fire training. Static experiments ran for 9 weeks to determine the fate of the combined explosive constituents in soil by monitoring the rate of degradation.
Composition B Comp B is a commonly used military formulation composed of the toxic explosive compounds 2,4,6-trinitrotoluene TNTand hexahydro-1,3,5-trinitro-1,3,5-triazine RDX. To obtain more quantitative information as well as to provide potential prediction methods, dissolution models have also been developed [6,7,10,11,21].
Two similar approaches were used for modeling dissolution of HE particles in the soil columns; one included dispersion in the bulk liquid phase, while the other did not. The yield of a detonation is the fraction of HE that detonates. Any type of detonation deposits HE residues on the ground surface. In addition ET corrects the adiponectin responsiveness of CACs, and thereby might promote endogenous repair of damaged endothelium. Most of the information available on fate and transport of explosives is for the subsurface environment.2002a, Lynch et al.
Cycling between flow and no-flow conditions had a small effect on the dissolution rates and effluent concentrations; however, TNT dissolution from Comp B was enhanced under intermittent-flow conditions.2002 reported dissolution kinetics of HE compounds and formulations in batch reactors and found that dissolution rates generally increased with temperature and particle surface area. Adipo improves the migratory capacity of CACs in response to SDF1, partially through an upregulation of CXCR4.
Two HE formulations, C4 and Comp B, were studied to determine RDX, HMX, and TNT dissolution rates, and a dissolution model that included advection, dispersion, and film transfer resistance was developed to estimate steady state effluent concentrations. the pure crystals of TNT, RDX, and HMX, or their mixed residues, e.
Citation of trade names does not constitute an official endorsement or approval of the use of such commercial products. Contamination of military ranges by the use of explosives can lead to irreversible environmental damage, specifically to soil and groundwater.
TNT demonstrated the fastest dissolution rate followed by HMX and then RDX. Residues dissolve through the direct impact of precipitation events, by flowing surface runoff, or by percolating soil pore water.
