    @article{osti_, title = {Anaerobic transformation of TNT}, author = {Kulpa, C F and Roopathy, R}, abstractNote = {Most studies on the microbial metabolism of nitroaromatic compounds have used aerobic tempts to degrade nitroaromatics under aerobic microorganisms. In many cases attempts to degrade nitroaromatics under aerobic conditions results in no . TNT transformations may include reduction of one, two, or all three nitro groups to amines, and coupling of amino transformation products to form dimers. Formation of the two monoamino products, 2-ADNT and 4-ADNT, are energetically favored [ ] and are typically observed in TNT-contaminated soils and by:

    Remediation of TNT-Contaminated Soil by Cyanobacterial Mat. EPA Grant Number: RC Subproject: this is subproject number , established and managed by the Center Director under grant R (EPA does not fund or establish subprojects; EPA awards and manages the overall grant for this center). Both TNT and tetryl undergo extensive chemical transformation in soil, forming aminodinitrotoluene isomers and N-methyl-2,4,6-trinitroaniline residues, respectively, along with a series of unknowns. After 60 days, only 30% of the amended TNT and 8% of the amended tetryl remained unchanged in the soil.

    While TNT is not identified as an emerging contaminant by the Department of Defense (DoD), this compound accounts for a large part of the explosives contamination at active and former U.S. military installations. With its manufacturing impurities and environmental transformation products, TNT presents various health and environmental Size: KB. TNT is composed of the elements carbon, oxygen and nitrogen. When TNT explodes it forms several covalent gases: CO, CO 2 and N 2 that are very stable. The production of these very low energy (stable) bonds means that a great deal of energy is released. It should be noted that most explosives contain these same elements.

The TNT transformation products TNB, TNBA, 2-amino-4,6-DNT and 4-amino-2, 6-DNT were generally found in concert with TNT. In addition, dinitroaniline, a reduction product of TNB.

Identification of TNT Transformation Products in Soil Marianne E. Walsh and Thomas F. Jenkins June Prepared for U.S. ARMY WATERWAYS EXPERIMENT STATION. Long‐term availability and fate of TNT and its transformation products must be understood to predict environmental impact and develop appropriate remediation strategies.

Sorption and transport in surface soil containing solidphase TNT are particularly critical, since nonlinear sorption isotherms indicate greater TNT availability for transport. Water extracts of soil samples of the former ammunition plant “Tanne” near Clausthal-Zellerfeld, Lower Saxony, Germany, were investigated for highly polar oxidized 2,4,6-trinitrotoluene (TNT) metabolites.

The ability of plants to uptake and transform 2,4,6-trinitrotoluene (TNT) was investigated using the aquatic plant Myriophyllum spicatum, axenic Myriophyllum aquaticum, and Catharanthus roseus hairy root cultures.
