目的了解我国部分城市水源水、末梢水中贾第鞭毛虫和隐孢子虫(以下简称“两虫”)的污染情况。方法于2014年丰水期(8—10月)、枯水期(11—12月)分别选取我国北、南、中部地区的哈尔滨、合肥、北京三地,对其水源水及末梢水进行了“两虫”的检测。结果三地丰水期、枯水期的水源水、末梢水中均有“两虫”的检出。60件水源水中,贾第鞭毛虫和隐孢子虫的超标率分别为10.0%和26.7%;60件末梢水中,贾第鞭毛虫均达标,隐孢子虫的超标率为1.7%;枯、丰水期水源水隐孢子虫的超标率均高于贾第鞭毛虫,枯、丰水期水源水“两虫”的超标率均高于末梢水。结论三地区水源水、末梢水中均有“两虫”不同程度的污染。
Objective To understand the pollution status of Giardia and Cryptosporidium in the water and peripheral water of some cities in China (hereinafter referred to as “two insects”). Methods The water source and the peripheral water in the north, south and central regions of China were selected for the wet season (August-October) and the dry season (November-December) in 2014, Two insects “test. Results During the wet season and the dry season, both the water and the peripheral water in the three areas had the detection of ”two insects“. In 60 water sources, the over-standard rates of Giardia lamblia and Cryptosporidium were 10.0% and 26.7%, respectively. The rate of Giardia was up to 1.7% The over-standard rate of Cryptosporidium in the water source period was higher than that in the gidget, and the over-standard rates of the water source water and the ”two worms" in both dry and wet periods were higher than that of the peripheral water. Conclusions The water sources and the peripheral water in the three areas all have different levels of pollution.
