目的 通过对北京市某区游泳场所水质中氰尿酸含量进行测定和卫生学调查,了解辖区泳池场所中氰尿酸的水平及其相关因素,为制定相关卫生标准提供科学数据。方法 2018年(4—8)月,选取使用氯化异氰尿酸酯类消毒剂的游泳场所,采集泳池水,分析池水温度、浑浊度、尿素、pH值、游离性余氯和氰尿酸6项指标,采用偏相关检验方法分析游泳池水质中氰尿酸含量及其相关因素。结果 氰尿酸中位数为23.0 mg/L,合格率为70.6%。游泳场所经营类型、结构设计、强制淋浴设备与否和消毒剂加药方式对氰尿酸合格率具有影响,其中学校泳池氰尿酸合格率最高,宾馆饭店其次,社会营利性泳池最低,露天泳池氰尿酸合格率最高,室内有窗泳池氰尿酸合格率高于室内无窗泳池氰尿酸合格率;有强制淋浴、机器自动加药的泳池氰尿酸合格率均高于无强制淋浴、人工加药泳池氰尿酸合格率,差异均具有统计学意义(P<0.05)。泳池温度和尿素与氰尿酸含量呈正相关关系。结论 某区游泳池中氰尿酸合格率不高,泳池温度和尿素与氰尿酸含量呈正相关关系,建议管理者合理选择消毒剂种类,应继续关注泳池中氰尿酸含量,及时更换泳池水,保障游泳者的身体健康。

Objectives To determine the level of cyanuric acid in swimming pools and related factors in the water quality of swimming pools in a certain area, and to provide scientific data for the development of relevant sanitary standards. Methods From April to August in 2018, swimming pools using chlorinated isocyanurate disinfectants were selected to collect pool water, and analyzed six indicators including pool water temperature, turbidity, urea, pH value, free residual chlorine and cyanuric acid. Relevant basic information were collected and the cyanuric acid content and related factors in swimming pool water quality were analyzed by partial correlation test. Results The median cyanuric acid was 23.0 mg/L, and the qualifed rate was 70.6%. Different swimming places, different structure design, forced shower, and different disinfectant dosing method had an effect on the qualified rate of cyanuric acid. The school pool had the highest qualified rate of cyanuric acid, followed by hotels and restaurants, and the lowest was social for-profit swimming pools. For the open-air swimming pool cyanuric acid, the pass rate was the highest, and the qualified rate of cyanuric acid in the indoor window swimming pool was higher than the cyanuric acid qualified rate in the indoor windowless swimming pool, and the qualified rate of cyanuric acid in the swimming pool with forced shower and automatic machine dosing was higher than that of the compulsory uric acid in the artificial dosing pool. The qualified rate was statistically significant (P<0.05). Pool temperature and urea were positively correlated with cyanuric acid content. Conclusions The qualified rate of cyanuric acid in the swimming pool of a certain area was not high. The temperature of the swimming pool and the content of urea and cyanuric acid were positively correlated. It is recommended that the manager choose the type of disinfectant reasonably. The cyanuric acid content in the swimming pool should be continuously paid attention to, and the swimming pool water should be replaced in time to protect the swimmers' health.
