Phytoremediation of Explosives using Transgenic Plants
In the past century, several explosive compounds have become the major soil contaminants causing health and economic challenges to the society. In the U.S. alone millions of hectares of land are contaminated by various forms of explosives. The two most dangerous explosives, 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5trinitro-1,3,5-triazine (Royal Demolition Explosive; RDX), are major enviro...
متن کاملسالمسازی بیولوژیکی خاکهای آلوده به ترکیبات پرانرژی
The explosives, in manufacturing, transporting and using at military installations, caused to pollution of ground and sub-ground waters, soils and sediments. Soil is posed as a relationship between water, weather and plants and animals existence of a zone. Therefore, soil health is a necessary matter. So, in order to suppression from environmental issues and human detriment, polluted soil impro...
متن کاملStimulating the anaerobic biodegradation of explosives by the addition of hydrogen or electron donors that produce hydrogen.
The anaerobic biodegradation of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), and 2,4,6-trinitrotoluene (TNT) by a methanogenic mixed culture was investigated. Microcosms containing a basal medium and the mixed culture were amended with ethanol, propylene glycol (PG), butyrate or hydrogen gas as the electron donor and a mixture of TNT (50...
متن کاملComposition of explosives by electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry.
Commercial explosives are complex mixtures that contain not only the active explosive agent(s) but also a host of other organic and inorganic compounds. The ultrahigh mass resolving power (m/delta m50% >200,000) and mass accuracy (<1 ppm) of electrospray ionization Fourier transform ion cyclotron resonance (ESI FTICR) mass spectrometry allow for definitive identification of various species in T...
متن کاملThe Fate of Nitroaromatic (tnt) and Nitramine (rdx and Hmx) Explosives in Fractured and Weathered Soils
We investigated the fate of explosives compounds in slurries containing fractured and weathered soil particles. Three soils were crushed with a piston to emulate detonation-induced fracturing. We used X-ray diffraction, scanning electron microscopy and gas adsorption surface area measurements to quantify the mineralogies and surfaces of the weathered and fractured soil particles. Soil batch slu...
