目的了解大连市游泳池水水质卫生状况,保障游泳者身体健康,为加强游泳池的卫生管理提供科学依据。方法按照《公共场所卫生监测技术规范》(GB/T 17220-1998)随机采集游泳池水样;按照《公共场所卫生标准检验方法》(GB/T 18204-2000)对游泳池水进行检验;根据《游泳场所卫生标准》(GB 9667-1996)进行水质评价。结果 2009-2012年共采集水样575份,合格388份,总合格率为67.5%,合格率间差异有统计学意义(χ2=20.23,P<0.001),2009年合格率最低为58.7%,2012年合格率最高为84.9%。各指标间合格率有统计学意义(χ2=229.36,P<0.001),其中浑浊度和大肠菌群合格率最高为99.7%,余氯合格率最低为80.5%。各年各指标间余氯和细菌总数合格率有统计学意义(χ2=56.95,P<0.001;χ2=8.30,P<0.05),其他指标在各年间没有统计学意义。结论大连地区游泳池水的卫生质量仍存在一些问题,应加强对游泳场所的卫生监管工作。
Objective To understand the sanitary status of swimming pool water in Dalian and to ensure the health of swimmers and provide a scientific basis for strengthening the health management of swimming pools. Methods Pool water samples were collected at random according to the Technical Specifications for Sanitation Monitoring in Public Places (GB / T 17220-1998); the swimming pool water was inspected in accordance with the “Public Health Standard Test Method” (GB / T 18204-2000); “ Place health standards ”(GB 9667-1996) for water quality evaluation. Results A total of 575 water samples were collected from 2009 to 2012, with a total of 388 passes. The total pass rate was 67.5%. There was significant difference between the pass rates (χ2 = 20.23, P <0.001). The lowest passing rate in 2009 was 58.7% The highest pass rate in 2012 is 84.9%. The passing rate of each index was statistically significant (χ2 = 229.36, P <0.001), of which turbidity and coliform prevalence rate was the highest 99.7%, the lowest residual chlorine rate of 80.5%. The passing rate of residual chlorine and total bacteria in each index between each year was statistically significant (χ2 = 56.95, P <0.001; χ2 = 8.30, P <0.05). Other indexes had no statistical significance in all years. Conclusion There are still some problems in the hygiene quality of swimming pool water in Dalian. Health supervision of swimming pool should be strengthened.
