Solid-state nitrogen-15 nuclear magnetic resonance analysis of biologically reduced 2,4,6-trinitrotoluene in a soil slurry remediation.
Soil contaminated with 2,4,6-trinitrotoluene (TNT) and spiked with [14C]- and [15N3]-TNT was subjected to an anaerobic-aerobic soil slurry treatment and subsequently analyzed by radiocounting and solid-state 15N nuclear magnetic resonance (NMR) spectroscopy. This treatment led to a complete disappearance of extractable radioactivity originating from TNT and almost all of the radioactivity was r...
متن کاملFate and metabolism of [15N]2,4,6-trinitrotoluene in soil.
The fates of the labels from [14C] and [15N] trinitrotoluene were analyzed in bioreactors under aerobic conditions in soil treated by a fungal bioremediation process with Stropharia rugosoannulata and in control soil. Up to 17.5% of the 15N label had a different fate than the 14C label. Three N-mineralization processes were identified in detailed experiments with [15N]TNT. About 2% of the 15N l...
متن کاملComparison of Nitroaromatic Compounds Metabolites Types by Sequencing Performance of Anaerobic-Aerobic and Aerobic-Anaerobic Processes
Introduction: Xenobiotic contamination is a global concern. Nitroaromatic compounds enter the environment through ammunition, ordnance disposal, burning the outdoors, and leakage of ammunition. Thirty percent of explosives enter the environment without any change, which can cause pollution of soil, water, and health concerns. So, effective remediation of the contaminated area is necessary. Mat...
متن کاملImproved removal of Trinitrotoluene (TNT) from contaminated soil by inducing aerobic process: kinetic and chemical byproducts
This study describes the biological degradation of TNT by using induced aeration. Three plastic reactors were used. In each reactor 3 kg of soil were used. In order to increase the porosity of the soil, sawdust was added to soil. Textile wastewater treatment plant sludge was also added to soil. TNT at the concentrations of 1000 mg/kg of soil was added thereafter. Rhamnolipid biosurfactant at th...
متن کاملImpact of 15N-labeled rice straw and rice straw compost application on N mineralization and N uptake by rice
Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...
