摘　　要：目的了解太湖水中微囊藻毒素(MC)的污染情况。方法于2001年7、11月采集太湖水样12件,每件50ml,装入灭菌的塑料瓶中;捕捉鲤形目和鲶形目的主要鱼种7属,共计28尾。用ELISA法对太湖源水的水样和鱼样进行MC含量的检测。结果太湖水样均检出MC。7月水样MC含量均值为9874.8pg/ml,高于11月(142.8pg/ml),差异有统计学意义(t=3.305,P=0.003)。主要鱼类体内均检出MC。其中,肝脏中MC的含量均值为27.84ng/g,高于肌肉中MC的含量均值(3.97ng/g),差异有统计学意义(t=5.933,P=0.001)。结论太湖水域中的自然水体和鱼体内已不同程度地含有MC。Objective To know the pollution situation by mierocystin （MC） in Tai Lake in Wuxi. Methods The MC content in 12 water samples and 28 fish samples in the Tai Lake were determined by ELISA. Results The positive rates of MC in water samples and fish samples were 100%. The mean content of MC in water samples was higher in July （9 874.8 pg/ml） than in November （142.8 pg/ml）. The mean content of MC in the livers was 27.84 ng/g, in the muscle it was 3.97 ng/g. Conclusion The Tai Lake has been contaminated by microcystin and it can be detected in the fish living in the lake.
