摘　　要：为合理利用水资源，为改善饮水卫生提供依据，应用竞争酶联免疫吸附试验，对于１９９７年９月至１２月间从江苏海门、泰兴、淮安和扬中４个县（市）收集的各类居民接触用水水样和１９９６年８月至９月间从湖周７个自来水厂的源水和出厂自来水样进行微囊藻毒素（ＭＣ）测定。结果在４个地区的沟塘水与河水中均检测出低浓度ＭＣ，沟塘水样ＭＣ检出率在１６７％～４２８％之间，而河水水样ＭＣ检出率均约为１８％；另从某湖周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２８１３５３００ｎｇ／Ｌ之间；并在３个自来水厂的出厂水中检出低浓度的毒素（１２８１４００ｎｇ／Ｌ）。结果提示ＭＣ污染在江苏一些地区比较常见，采用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。To provide scientific basis for the retional use of water sources and improvement of drinking water quality,the microcystins(MC) in water samples collected from Haimen,Taixin,Huaian and Yangzhong counties,Jiangsu province in SepDec,1977 and source and tap water of seven waterworks around a lake in summer was detected by enzymelinked immunosorbent assay(ELISA)MC was determined in 167%￣428% of ditch water samples and about 18% of river water samplesMC was also determined in source water from all the seven waterworks,and the concentration range was 281￣35 300ng/LFrom three waterworks,low concentration of MC (128￣1 400ng/L)was detected in the tap waterThe result suggested that micricystins in source water could not be removed completely by conventional disinfection treatment
