摘要
目的调查深圳市罗湖区各游泳场馆对于尿素降解剂的使用情况,探讨使用其作为一种新型的净水剂对游泳人群健康的影响。方法在2019—2021年间,筛选出辖区内119家游泳人数较多的游泳馆作为调查对象,对场馆负责人进行调查(包括询问泳池水的更换频次和尿素降解剂的使用情况)及采集水样,获取游泳场馆泳池水中尿素和氨氮的基线数据,进行统计分析。结果调查共采集了119家游泳场所的泳池水样,其中尿素的合格率为81.51%,氨氮的合格率为46.22%,使用过尿素降解剂的游泳馆有98家,占比82.35%。结论深圳市罗湖区的游泳场馆对尿素降解剂的使用率较高,其使用频次越大,氨氮浓度水平则越高,应引起重视,加强对辖区内游泳馆水质监测的管控。
Objective To investigate the use of urea-reducing agents in various swimming venues in Luohu district of Shenzhen,China,and to explore the influence of this new water-purifying agent on the health of swimmers.Methods In 2019—2021,119 swimming venues with relatively large number swimmers in this district were selected for investigation,and field personnel investigated the persons in charge(about the frequency of changing the water and the use of urea-reducing agents)and collected water samples to obtain the baseline data of urea and ammonia nitrogen in water for health statistics.Results A total of 119 swimming pool water samples were collected,and the qualification rates of urea and ammonia nitrogen were 81.51%and 46.22%,respectively.A total of 98 swimming venues used urea-reducing agents,accounting for 82.35%.Conclusion There is a relatively high rate of use of urea-reducing agents in swimming venues in Luohu district of Shenzhen,and the more frequency of using urea-reducing agents,the higher mass concentration of ammonia nitrogen.Therefore,it is necessary to strengthen the control of water quality monitoring in swimming venues within the jurisdiction.
