| 中文摘要 | The fate of triazophos (TAP) in a hydroponic phytoremediation system planted with Canna indica Linn. was investigated. After 7-day exposure, diverse concentrations of TAP were detected in different plant organs, with a maximum in roots to a minimum in leaves, which demonstrated a TAP transport pathway from the root to the shoot. It was also found that more TAP was taken up by plants in this phytoremediation system than in a microbes-inhibited one (p<0.05), illustrating the combination effect of microbes and plants on TAP dissipation. After another 7-day culti-vation in TAP-free solution, the concentrations of TAP in plant organs decreased by 48.4-99.9%, probably due to faster degradation or transportation of TAP through the plant. Analysis with liquid chromatographymass spectrometry indicated that TAP was probably metabolized through a two-phase process in the phytoremediation system, with triazophos oxon, phenyltriazolol, and two conjugated compounds O-ethyl O-glucuronic acid O-(1-phenyl-1H-1,2,4-triazole-3-yl) phosphate and O-ethyl O-glucuronic acid O-(1-phenyl-1H-1,2,4-tria-zole-3-yl) phosphorothioate as products. |
