The ecological impact of explosives are effects both unexploded explosives and post-explosion by-products have on the environment.[1]
Residual post explosion products can partition between multiple environmental compartments: aquatic, soil, atmosphere, biosphere.[2][3]
Magnitude of exposure
Explosives have important applications in the military and in both mining and construction work. In fact, the manufacture of explosives comprises a large amount of the chemical industry.[4] In the course of their production, handling, loading, and disposal, explosives are released into the environment. It is there that they are dispersed by mechanical processes or dissolved or volatilized and partially converted to secondary products.[4] Over the past 150 years, millions of tons of explosives have been produced for military applications and other activities that have led to the accidental contamination of energetic materials in the soil and groundwater.[5] Exact numbers cannot be obtained and estimations are generally conservation because people make their own bombs, which is not a small activity in regions dealing with armed conflict. The United States Army had estimated that over 1.2 million tons of soils have been contaminated with explosives on their training grounds alone. In the year 2004, it was estimated that 2,520,000 metric tons of explosive agents were sold for consumption in the United States alone.[6] Figure 1 shows the world consumption of explosives in 2008.[7]
Generally, explosives are dispersed mainly when used in combat. Most explosives are used as warfare agents by militaries globally. However, modern uses for 2,4,6-trinotrotoluene (TNT) are associated with construction and demolition, rather than combat. Because of its use in construction and demolition, it has become perhaps the most widespread explosive, and thus its toxicity is the most characterized and reported. The concentration of TNT in contaminated soil can reach 50 g kg-1 of soil, where the highest concentrations can be found on or near the surface. In the last decade, the United States Environmental Protection Agency (USEPA) has declared TNT a pollutant whose removal is priority.[8] The USEPA maintains that TNT levels in soil should not exceed 17.2 gram per kilogram of soil and 0.01 milograms per liter of water.[5]
