| Most of army depots contaminated with co-contaminants. 2,4,6-trinitrotoluene(TNT) and heavy metais. In phytormediation for the TNT, heavy metals may inhibit mineralization, transformation and sequestration of TNT by the plant. W studied effect of cadmium on TNT degradation and transformation by Abutilion avicenneae in hydroponic cultures. When cultured in 20 §·TNT/L and 1.3 §·Cd/L. the plant displayed phytotoxicities; reduction of leaf fresh, leaf roll, chlorosis, leaf loss and fresh weight loss. Phytotoxicity was severer in the combined contaminnts than in single contaminant. Because A. avicennae uptake just a little cadmium, 1.3 §·Cd/L induded in the TNT medium did not influece significanfly TNT transformation, translocation and distrivution by A. Therefore, the soil solution containing cadmium would not affect TNT degradation by Abutilion avicennae in Amy depots polluted with TNT. |
