    Analysis and Evaluation for Drinking Water from Kitchens of Some Restaurants, Schools and Kindergartens in Henan Province

      摘要
    • 摘要:
      目的 了解河南省餐饮用水水质状况, 为餐饮用水监管提供科学依据。
      方法 抽检全省18个地级市及28个县的部分饭店、学校及幼儿园食堂餐饮用水, 采用《生活饮用水标准检验方法》(GB/T 5750-2006) 检测铅、砷、汞、镉4种毒理指标及菌落总数、总大肠菌群、耐热大肠菌群、大肠埃希菌4项微生物指标, 按照《生活饮用水卫生标准》(GB 5749-2006) 及重金属污染单因子指数法进行分析与评价。
      结果 共抽检215份水样, 合格145份, 总合格率67.44%。4种重金属指标全部合格, 均为非污染程度; 菌落总数、总大肠菌群、耐热大肠菌群及大肠埃希菌合格率分别为73.02%、77.67%、81.86%和90.23%;市区餐饮用水合格率(74.05%)高于县区(64.29%), 差异有统计学意义(χ2等于11.854, P等于0.001);大、中、小饭店、学校及幼儿园食堂餐饮用水合格率分别为81.63%、64.29%、45.46%、60.87%和73.81%, 差异有统计学意义(χ2等于11.272, P等于0.024);集中式供水合格率(70.59%)明显高于分散式供水(9.09%), 差异有统计学意义(χ2等于9.185, P等于0.002)。
      结论 河南省餐饮用水合格率较低, 主要原因是微生物污染, 其中小饭店、分散式供水污染最重。

       

      Abstract:
      Objectives To know the quality of drinking water from the kitchens of restaurants, schools and kindergardens in Henan Province and provide authorities with the data for the water supervision.
      Methods After sampling from the kitchens of restaurants, schools and kindergartens in 18 prefecture-level cities directly under Henan Province and 28 counties in the province, detect Pb, As, Hg, Cd, standard plate-count bacteria (SPCB), total coliforms (TC), thermotolerant coliform bacteria (TCB) and E. coli (EC) according to GB/T 5750-2006, then analyze with single factor index and evaluate according to GB 5749-2006.
      Results 145 among 215 samples (67.44%) meet GB 5749-2006. Pb, As, Hg and Cd in all the samples pass GB 5749-2006. The rates of passing GB 5749-2006 for SPCB, TC, TCB and EC are 73.02%, 77.67%, 81.86% and 90.23% respectively with statistical significance(χ2=11.854, P=0.001). The rates of passing GB 5749-2006 for samples from big, middle and small restaurants, schools and kindergartens are 81.63%, 64.29%, 45.46%, 60.87% and 73.81% respectively with statistical significance(χ2=11.272, P=0.024). The rate of passing GB 5749-2006 for samples from centralized water supply(70.59%)is much more higher than that from non-centralized water supply(9.09%)with statistical significance(χ2=9.185, P=0.002).
      Conclusions The rate of passing GB 5749-2006 for the drinking water from the kitchens in Henan Province is lower mainly because of microbe contaminations, especially the water from small restaurants and the non-centralized water supply.
