目的了解北京市怀柔区游泳池水质卫生状况,预防传染性疾病的发生,保障游泳者的身体健康。方法 2012—2013年采集怀柔区6家游泳池水样,依据国家标准对pH值、浑浊度、尿素、游离性余氯、细菌总数、大肠菌群等项目进行检测。结果共检测水样246件,合格190件,合格率为77.2%,2年合格率差异有统计学意义(χ2=48.9,P<0.05)。其中合格率最低的是游离氯和尿素,均为88.2%;其次是细菌总数,合格率为93.9%;6项指标合格率差异有统计学意义(χ2=87.054,P<0.05)。游泳淡季合格率高于游泳旺季的合格率,二者差异有统计学意义(χ2=7.35,P<0.05)。室内与室外游泳池水质合格率差异无统计学意义(χ2=2.68,P>0.05)。不同星级宾馆的游泳池水质合格率差异有统计学意义(Z=4.210,P<0.05)。结论怀柔区游泳池水质合格率不高,相关监管部门应加强对游泳池水质的监测工作,为游泳者提供一个健康的游泳环境。
Objective To understand the sanitary condition of swimming pool in Huairou District of Beijing, prevent the occurrence of infectious diseases and ensure the physical health of swimmers. Methods Six swimming pools in Huairou district were collected from 2012 to 2013. According to the national standards, pH, turbidity, urea, free residual chlorine, total bacteria and coliform bacteria were detected. Results A total of 246 water samples were tested, and 190 were qualified with a pass rate of 77.2%. There was a significant difference in 2-year pass rates (χ2 = 48.9, P <0.05). The lowest pass rate was free chlorine and urea, both were 88.2%; followed by the total number of bacteria, the pass rate was 93.9%; 6 indicators pass rate difference was statistically significant (χ2 = 87.054, P <0.05). The passing rate of swimming in the off-season was higher than the passing rate in swimming season, the difference was statistically significant (χ2 = 7.35, P <0.05). The passing rate of indoor and outdoor swimming pool water quality difference was not statistically significant (χ2 = 2.68, P> 0.05). The swimming pool water quality pass rates of different star hotels were significantly different (Z = 4.210, P <0.05). Conclusions Huairou district swimming pool water quality pass rate is not high, the relevant regulatory authorities should strengthen the monitoring of swimming pool water quality for the swimmer to provide a healthy swimming environment.
