【摘要】：目的了解银川市中小学体育馆空气卫生质量现况,为更好地改善空气质量提供依据。方法抽取银川市中小学体育馆12所,对馆内CO_2、甲醛、可吸入颗粒物(PM2.5)、温度、相对湿度进行调查,参考《体育馆卫生标准》(GB9668-1996)(以下简称《标准》)中标准值进行判断。结果银川市中小学体育馆CO_2体积百分比浓度在开馆前均小于国家标准值最高限(0.15%),符合《标准》规定;但在运动1 h后CO_2体积百分比浓度均大于0.15%,16.7%的中学CO_2体积百分比浓度高达0.25%,超出《标准》最高值66.7%;24 h CO_2体积百分比浓度均值均大于0.15%,不符合《标准》规定。甲醛质量体积浓度开馆后1 h均值均大于国家标准值最高限(0.12 mg/m3),不符合《标准》规定;16.7%的小学高达0.21 mg/m3,超出《标准》最高值75%。可吸入颗粒物(PM2.5)在开馆前均小于国家标准值最高限(0.25 mg/m3),符合《标准》规定;但运动1 h后普遍升高并超过规定值,16.7%的中学高达0.62 mg/m3,超出《标准》最高值148%;24 h均值也均0.25 mg/m3,不符合《标准》规定。温度在开馆前和运动1 h后均≥16℃的国家最低限,符合《标准》标准;相对湿度开馆前均低于《标准》限值,开馆1 h后虽略有提升,但仍不符合《标准》规定。结论银川市中小学体育馆空气卫生质量不容乐观,应积极采取措施进行改善。
[Abstract]:Objective to understand the current situation of air health quality in Yinchuan's primary and secondary school gymnasium to provide a basis for better air quality improvement. Methods 12 primary and secondary school gymnasiums in Yinchuan were selected to investigate the CO_2, formaldehyde, inhalable particulate matter (PM2.5), temperature and relative humidity in the library, and refer to the gymnasium hygienic standard (GB9668-1996) (hereinafter referred to as < standard >). The CO_2 volume percentage concentration in Yinchuan's primary and secondary school gymnasium is less than the national standard maximum (0.15%) before the opening of the gymnasium, which is in line with the standard of < standard >, but the volume percentage concentration of the CO_2 volume is more than 0.15% after the 1 h movement, and the CO_2 volume percentage of the middle school is 0.25%, exceeding the < standard > the highest value 66.7%; 24 h CO The mean value of _2 volume percentage concentration is more than 0.15%, which does not conform to the standard of < standard >. The 1 h mean of formaldehyde volume concentration is greater than the national standard maximum (0.12 mg/m3), and does not conform to the standard of < standard >; 16.7% primary school is up to 0.21 mg/m3, and the highest value 75%. inhalable particles (PM2.5) are less than the national standard value before the opening of the library. The maximum limit (0.25 mg/m3) is in conformity with the standard of < standard >, but the exercise is generally elevated and exceeded the prescribed value after 1 h, 16.7% of the middle school is up to 0.62 mg/m3, exceeding the highest value of < standard > 148%; the 24 h mean is also 0.25 mg/m3, which is not in accordance with the standard. The national minimum limit of the temperature before the opening and after the movement 1 h is equal to < standard > standard; relative humidity is open. The pre library was lower than the standard < standard >. Although the opening 1 h was slightly improved, it still did not conform to the standard. Conclusion the air hygiene quality of Yinchuan primary and secondary school gymnasium is not optimistic, and measures should be taken to improve it.
