| Abstract: |
| In order to evaluate the ecological toxicity of three antibiotics[chlortetracycline（CTC）, norfloxacin（NFLX）and sulfametoxydiazine（SMD）], three vegetables, cucumber（No. 4 of New Jinyan）, rape（QiRu Green） and Chinese cabbage（Huangyang）, were grown in hydroponic condition to observe their shoot and root elongation as well as half-inhibition concentration（IC50） under six different concentrations of CTC and SMD（0, 10, 30, 50, 70, 90 mg·L-1）, and NFLX（0, 20, 40, 80, 160, 320 mg·L-1）. Results showed that：（1）roots were more sensitive than shoots;（2）ecological toxicity of three antibiotics was CTC>SMD>NFLX for cucumber, SMD>CTC>NFLX for rape, and SMD>NFLX>CTC for Chinese cabbage;（3）tolerance of vegetables to SMD and CTC was cucumber>Chinese cabbage>rape, whereas NFLX had the largest impact on Chinese cabbage, followed by cucumber and rape. These results demonstrate the potential ecological impacts of antibiotics in the environment. |
