北京饮用水源病毒污染研究

A STUDY OF VIRUSES CONTAMINATION IN DRINKING WATER SUPPLIES IN BEIJING

对北京地区地表饮用水源从1986年11月到1988年10月在四个采样点逐月进行病毒污染检测,结果密云水库为0～0.62PFU/L(平均为0.08),怀柔水库为0～1.77PFU/L(平均为0.20),官厅水库三家店水样为0～2.68PFU/L(平均为0.27),团城湖水样为0～0.73PFU/L(平均为0.17)。该结果与国内外有关资料相比,表明当前北京地表饮用水源病毒污染尚不明显。

Surface water was used as drinking-water supplies now because of excessive extraction of the reduced ground water. We investigated virus contamination in the surface water from four sampling spots once a month from November 1986 to October 1988. The results were as following: Miyun reservoir 0-0.62PFU/L, Huairou reservoir 0-1.77PFU/L, Guanting reservoir at Sanjiadian 0-2.68PFU/L, and Lake Tuancheng 0-0.73PFU/L. These results suggest that virus contamination in drinking-water supplies in Beijing is currently not obvious as compared with that from Shanghai and abroad. They provide the basic reference for the protection of water supplies and quality control of tap water in Beijing.
