农村学校饮用水水质安全影响因素及其改善对策

Influence factors and improvement measures for drinking water quality and safety in rural schools in Hunan province

  • 摘要:
      目的  了解湖南省农村学校饮用水安全现状,科学评价存在的主要风险,提出对策建议,为政府职能部门制订有效措施,提高学校饮用水安全水平提供依据。
      方法  于2016年5 — 10月随机抽取湖南省18个县区83所不同层次学校,以《生活饮用水卫生标准》(GB 5749 – 2006)为依据,按照《生活饮用水标准检验方法》(GB5750 – 2006)对饮用水的卫生指标进行检测与评价。
      结果  湖南省农村学校饮用水总体合格率为40.96 %,不合格率为59.04 %;毒理学指标合格率为100 %,感官性状和一般化学指标合格率为85.5 %,微生物指标合格率为69.4 %,消毒剂指标合格率为45.2 %。学校层次和地域对农村学校饮用水合格率无明显影响;但经济发达程度、供水方式对农村学校饮用水合格率具有明显影响。二元logistic回归分析结果显示,经济发展程度与农村学校饮用水合格率呈正相关,集中式供水优于小型集中式供水和分散式供水。
      结论  湖南省农村学校生活饮用水合格率有待提高,经济欠发达的农村学校和分散式供水的农村学校应列为水质安全监管和质量改造的重点。

     

    Abstract:
      Objective  To examine current situation of drinking water safety and its main impact factors in rural schools in Hunan province for providing evidences to develop effective measures on improving drinking water safety in the schools by governmental agencies.
      Methods  We conducted monitoring surveys on drinking water quality in 83 schools randomly selected in 18 counties or districts in Hunan province from May to October 2016. National Standard Test Method for Drinking Water (GB5750-2006) and Standard for Drinking Water Hygiene (GB 5749-2006) were adopted in detection and evaluation of drinking water quality.
      Results  For all schools surveyed, the overall qualification rate of drinking water quality was 40.96% and the unqualification rate was 59.04%, with the qualification rate of 100% for toxicological indicators, 85.5% for sensory properties and general chemical indicators, 69.4% for microbial indicators, and 45.2% for disinfection indicators. The location and grade of the schools showed no obvious influence on the qualification rate of drinking water quality; however, the status of economic development and the way of drinking water supply had obvious influence on the qualification rate. The results of binary logistic regression analyses showed that the degree of economic development was positively correlated with the qualification rate and the centralized water supply was superior to the small centralized water supply and the decentralized water supply in drinking water quality.
      Conclusion  The qualification rate of drinking water quality in rural schools, especially in those located in economically underdeveloped regions or with decentralized water supply, in Hunan province needs to be improved.
