目的了解商丘市市农村学校集中式供水水质现状,为学校卫生监督提供科学依据。方法 2013-2015年对商丘市96个农村学校集中式供水监测点进行水质监测;依据《生活饮用水卫生标准》(GB/T5749—2006)对结果进行评价。结果共监测水样384份,合格率33.85%;3年的商丘市农村饮用水水样合格率呈逐年上升趋势,差异有统计学意义(χ~2=57.34,P<0.05),主要不合格指标为微生物指标氟化物、总硬度、溶解性固体和微生物学指标;各年的硫酸盐、氟化物合格率差异无统计学意义(χ_1~2=1.106、χ_2~2=0.577,P>0.05)。3年的枯、丰水期水样合格率差异无统计学意义(χ~2=3.768,P>0.05)。结论商丘市农村学校集中式供水水样合格率、检测指标总合格率均逐年升高,农村学校学生饮水含氟量仍较高,应值得关注。
Objective To understand the status quo of centralized water quality in rural schools in Shangqiu City and to provide a scientific basis for school health supervision. Methods From 2013 to 2015, 96 rural schools in Shangqiu City, centralized water supply monitoring points for water quality monitoring; based on “drinking water health standards” (GB / T5749-2006) to evaluate the results. Results A total of 384 water samples were tested with a pass rate of 33.85%. The qualified rate of rural drinking water samples in Shangqiu City increased year by year with a statistically significant difference (χ ~ 2 = 57.34, P <0.05) Indicators were indicators of fluoride, total hardness, dissolved solids, and microbiology. There was no significant difference in qualified rates of sulfate and fluoride between years (χ_1 ~ 2 = 1.106, χ_2 ~ 2 = 0.577, P> 0.05) . There was no significant difference in passing rate of water samples during the three years of dry and wet (χ ~ 2 = 3.768, P> 0.05). Conclusion Shangqiu rural schools centralized water supply water sample pass rate, test indicators of the total pass rate are increasing year by year, rural schools, students still have high fluoride content, should be noted.
