Evaluation of the Environmental Fate and Behavior of Munitions Materiel (Tetryland Polar Metabolites of TNT) in Soil and Plant Systems. Preliminary Evaluation of TNT-Polar Metabolites in Plants

摘要

A preliminary study was conducted to elucidate the nature of the polarmetabolites reported for plant tissues and xylem exudates following root accumulation of trinitrotoluene. Studies focused on the nature of the proposed conjugates of TNT-residues in xylem exudates of bush bean plants. Use of enzymatic methods failed to demonstrate that the conjugates were carbohydrate based, but acid hydrolysis indicated that the conjugates may be protein based. Of the five polar conjugates isolated from exudates, the presence of aminodinitrotoluene isomers and one unknown TNT residue was demonstrated. munitions, bioavailability, plant uptake and metabolism, environmental fate, RA3.
