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１６７％～４２８％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。
In order to make rational use of water resources and provide a basis for improving drinking water sanitation, the competitive enzyme-linked immunosorbent assay (ELISA) was used to test the data collected from 4 counties (cities) in Haimen, Taixing, Huaian and Yangzhong from September to December 1997 Contact with water samples and microcystin (MC) determinations from August 2007 to September 2009 Source water and tap water samples from seven waterworks in Lake Zhou. Results Low concentrations of MC were detected in ditches and river waters in four areas, and the detection rates of MC in ditches were between 167% and 428%, while those in water samples were all about Was 18%. In addition, the toxins were detected in the water samples collected from seven waterworks at different periods in a lake and the concentrations were in the range of 28135300ng / L. In the tap water of three waterworks, low concentrations were detected Of toxins (1281400 ng / L). The results suggest that MC pollution is more common in some areas of Jiangsu Province. The common disinfection of drinking water does not completely eliminate microcystin in water.
