北京市游泳池水中尿素检测结果分析

Analysis on detection results of urea residue in swimming pool water in Beijing

目的了解北京市游泳池水中尿素的污染情况,为促进游泳场所卫生管理提供科学依据。方法 2015年3—10月对北京市游泳场所进行随机抽检,检测尿素并分析不同地域、不同类型游泳池尿素合格率的差异。结果检测游泳池水1 572件,尿素合格率61.5%,其中5和6月的合格率最低。城区游泳池和周边区县游泳池水中尿素合格率之间差异有统计学意义（χ^2=134.22,P〈0.05）。按经营管理类型分组进行两两比较,宾馆泳池合格率为78.54%,与社会性泳池比较,χ^2=129.02,P〈0.05;与学校泳池比较,χ^2=15.92,P〈0.05;体育馆泳池合格率为86.27%,与社会性泳池比较,χ^2=58.97,P〈0.05;与学校泳池比较,χ^2=16.09,P〈0.05;学校泳池合格率为64.98%,与社会性泳池比较,χ^2=28.29,P〈0.05;社会性泳池尿素合格率最低,仅为45.7%。结论北京市游泳池水中尿素合格率偏低,应加强卫生管理。

[Objective]To study the urea residue of swimming pool water in Beijing,and provide scientific basis for improving hygiene management in swimming places.[Methods]The water samples were collected randomly from swimming places of Beijing and were tested the urea residue during March to October in 2015.The differences in qualified rate of urea residue between different regions and different types of swimming pool were compared.[Results]Totally 1 572 swimming water samples were detected and the total qualified rate of urea residue was 61.5%.The qualified rate of May and June was the lowest.The difference in qualified rate of urea residue was statistically significant between urban swimming places and suburban swimming places（χ^2=134.22,P〈0.05）.The pairwise comparison was conducted according to the operation and management types of swimming pool.The urea residue qualified rate of hotel swimming pool was 78.54%,which was higher than that of commercial swimming pool（χ^2=129.02,P〈0.05）and school swimming pool（χ^2=15.92,P〈0.05）.The urea residue qualified rate of gymnasium swimming pool was 86.27%,which was higher than that of commercial swimming pool（χ^2=58.97,P〈0.05）and school swimming pool（χ^2=16.09,P〈0.05）.The urea residue qualified rate of school swimming pool was 64.98%,which was higher than that of commercial swimming pool（χ^2=28.29,P〈0.05）.The urea residue qualified rate of commercial swimming pool was the lowest（45.7%）.[Conclusion]The urea residue qualified rate of swimming water in Beijing is low,and the hygiene management should be strengthened.
