摘　　要：对太湖梅梁湾水源水中的总藻毒素TMC[(TMC-LR)+(TMC-RR)]和胞外藻毒素EMC[(EMC-LR)+(EMC-RR)]进行了跟踪检测。结果表明,水体中TMC-RR、TMC-LR、EMC-RR、EMC-LR质量浓度平均分别为1.819μg/L、1.090μg/L、0.491μg/L和0.077μg/L,无锡市的主要水源地水质已受到微囊藻毒素的污染。提出,应加强水源地水体中微囊藻毒素浓度的监测,确保饮用水的安全。The total microcystins concentration and extracellular microcystin in source water of Meiliang Bay, Taihu Lake were detected on the time monitoring. The average concentrations of total microcystin - RR, LR and extracellular microcystin -RR, LR were 1. 819 μg/L, 1. 090 μg/L, 0. 491 μg/L, 0. 077 μg/L respectively. It indicated microcystins polluted the most of the source water in Wuxi city. The microcystins concentration monitoring in source water should be enhanced to protect the drinking water safety.
