目的了解南京市鼓楼区管道直饮水的卫生状况,为今后开展监督监测提供科学依据。方法2013—2015年对南京市鼓楼区3类245家委托单位的管道直饮水进行卫生监督监测。结果共检测291份管道直饮水,合格268份,合格率为92.10%;3年合格率分别为92.87%、89.38%和95.06%,2014年合格率有所下降;中学的管道直饮水卫生状况合格率(79.59%)最低。微生物指标菌落总数是致管道直饮水不合格的主要原因之一。结论南京市鼓楼区各类管道直饮水的总体合格率较高,但应进一步加强卫生监督监测,不断提高管道直饮水的卫生安全性。
Objective To understand the sanitary status of direct drinking water in pipelines in Gulou district of Nanjing and provide a scientific basis for monitoring and monitoring in the future. Methods From 2013 to 2015, we conducted sanitary supervision and monitoring on the direct drinking water of 245 entrusted units in 3 categories in Gulou District of Nanjing. Results A total of 291 drinking water samples were obtained, of which 268 were qualified. The pass rate was 92.10%. The pass rates in three years were 92.87%, 89.38% and 95.06% respectively. The passing rate in 2014 dropped slightly. Rate (79.59%) lowest. Microbiological indicators The total number of colonies is one of the main reasons for the unqualified pipeline drinking water. Conclusions The overall pass rate of direct drinking water in various types of pipelines in Gulou district of Nanjing City is relatively high. However, health supervision and monitoring should be further strengthened to continuously improve the hygiene and safety of pipeline drinking water.
