Abstract: Main sources of antibiotics in the environment were detected in sewage, medical wastewater and aquaculture wastewater. In 2013, the weight of the total use of antibiotics in China was about 1.62×105 t, of which 48% were human antibiotics and the rest were veterinary antibiotics. A lot of them still have the activity of antibiotics. They were accumulated in rivers and lakes by the surface runoff, and urban sewage pipe in end. These active substances are harmful to aquatic organisms, especially over longer time spans, and this hazard will expand further. The article briefly outlined the research about the ecotoxicological effects of norfloxacin(NFLX)on some aquatic organisms in recent years, based on cytochrome P450(CYP450)as an indicator of detection. The influencing mechanism of NFLX on CYP450 as selected indicators was introduced, and the feasibility methods for testing these indicators was discussed.

Key words: norfloxacin(NFLX), cytochrome P450(CYP450), aquatic organisms
