| Most of army depots contaminated with co-contaminants, 2,4,6-trinitrotoluene(TNT) and heavy metals. In phytoremediation for the TNT, heavy metals may inhibit mineralization, transformation and sequestration of TNT by the plant. We studied effect of cadmium on TNT degradation and transformation by Abutilion avicennae in hydroponic cultures. When cultured in 20 mgTNT/L and 1.3 mgCd/L, the plant displayed phytotoxicities; reduction of leaf fresh, leaf roil, chlorosis, leaf loss and fresh weight loss. Phytotoxicity was severer in the combined contaminants than in single contaminant. Because A. avicennae uptake just a little cadmium, 1.3 mgCd/L included in the TNT medium did not influece significantly TNT transformation, translocation and distribution by A. avicennae. Therefore, the soil solution containing cadmium would not affect TNT degradation by Abutilion avicennae in Army depots polluted with TNT. |
