利用环境卫生审核结果，对都市区X区中小学冬季空气质量进行了分析。分析期限定为2007年至2009年3年，得到以下结论： 1）小学教室气温、相对湿度、CO2浓度平均值符合学校环境卫生标准。 2）CO2观测值超过1500ppm标准值的比例，小学为30.5%，中学为58.5%。 3）中小学均存在室外温度越低，供暖利用率越高的明显趋势。在室外温度相同的条件下，中学供暖使用率高于小学。 4）在室外温度相同的条件下，中学教室的平均室温明显高于小学。中学各温度等级的平均二氧化碳浓度均超出标准值。
The air quality during winter period in elementary/secondary schools located in metropolitan district X was analyzed by using results of the environmental hygienic audit. The period of analysis was set as 3 years from 2007 to 2009. The following conclusions were obtained; 1) The average values of air temperature, the relative humidity, and CO2 concentration in classrooms of the elementary schools met the standard of school environmental hygiene. 2) The ratio of the CO2 observations exceeding the standard value of 1500 ppm in the elementary schools was 30.5 %, and that in the secondary schools was 58.5 %. 3) The clear tendency that the lower the outdoor temperature, the higher the heating usage ratio, was observed both in the elementary and the secondary schools. Under the same outdoor temperature condition, the heating usage ratio in the secondary schools was higher than that in the elementary schools. 4) Under the same outdoor temperature condition, the average room temperature in the classrooms of the secondary schools was significantly higher than that of the elementary schools. The average CO2 concentrations in the secondary schools exceeded the standard values under the all temperature classes.
