目的了解南通市游泳场所水质卫生状况,保障游泳者身体健康,为政府监管提供依据。方法对南通市区游泳场所池水p H值、浑浊度、尿素、游离余氯、细菌总数、大肠菌群进行监测,对监测结果进行统计分析。结果 2011年-2015年共监测游泳场所池水样本1 332份,总合格率为90.39%;不同季度、不同类型游泳场所池水总合格率和尿素合格率差异均有统计学意义(P<0.05)。第三季度游泳场所池水总合格率及尿素合格率均低于其他季度;社会经营性游泳场所池水合格率及尿素合格率均低于其他3类;室内游泳池水总体合格率与室外差异无统计学意义(χ2=3.594,P>0.05)。结论南通市区游泳场所池水总体合格率较高,合格率最低的项目为尿素,建议重点加强对社会经营性游泳场所、室外游泳场所和第三季度各游泳场所的卫生监督管理和卫生监测检测,同时强化游泳者健康卫生知识的宣传教育引导。
Objective To understand the water quality and hygiene status of swimming facilities in Nantong City and to ensure the physical health of swimmers and provide the basis for government regulation. Methods The p H value, turbidity, urea, free residual chlorine, total bacteria and coliform bacteria in swimming pool in Nantong City were monitored, and the monitoring results were statistically analyzed. Results A total of 1 332 batches of swimming pool water samples were monitored during 2011-2015, with a total pass rate of 90.39%. There was significant difference between the total passing rate and urea passing rate in different types of swimming pools in different quarters (P <0.05). The passing rate of pool water and passing rate of urea in the swimming pool in the third quarter were all lower than those in the other quarters. The passing rate of pool water and passing rate of urea in the social swimming pool were lower than the other three categories. There was no statistical difference between the overall passing rate of indoor swimming pool and the outdoor Significance (χ2 = 3.594, P> 0.05). Conclusion The overall qualified rate of swimming pool water in Nantong urban area is high, with the lowest passing rate of urea. It is suggested to strengthen the supervision and management of sanitation and hygiene of social swimming places, outdoor swimming places and swimming places in the third quarter, At the same time strengthen swimmers health and hygiene knowledge of education and guidance.
