摘　　要：应用酶联免疫吸附试验对于１９９６年８月至９月间从某湖周围７个自来水厂的源水和出厂自来水样进行微囊藻毒素测定。结果从７个自来水厂不同时期采集的源水样中均检测到此毒素，其浓度范围在２８０～３５３００ｎｇ／Ｌ之间；另外在３个自来水厂的出厂水中检出低浓度的毒素（１２８～１４００ｎｇ／Ｌ）。提示常用的饮水消毒处理并不能完全消除水体中的微囊藻毒素。The microcystins in source and tap water collected from seven waterworks around a lake in summer, 1996 were detected by enzyme linked immunosorbent assay(ELISA). Microcystins were determined in the source water from all the seven waterworks, and the concentrations ranged from 280 to 35300ng/L. Low concentrations of microcystins were also detected in the tap water of three waterworks. The results suggest that microcystins in source water could not be removed completely by conventional adding bleaching powder treatment.
