Children under 15 years spend over six hours per day in school buildings and are particularly vulnerable to the effects of poor indoor air quality (IAQ). However long-term monitoring of indoor environmental conditions is limited in Australian schools. This study evaluates IAQ in ten Australian school classrooms in the temperate settings of Victoria. Temperature, relative humidity, CO2 concentration, PM2.5 and PM10 were monitored over a period of one year. The temperature and relative humidity values in the monitored classrooms ranged between 18.7°C and 23.8°C and 44–63 RH%, respectively, indicating that the conditions have been mechanically controlled. The average air change (ACH) rates in the 10 school classrooms varied considerably (range: 0.7–4.83 ACH). The ventilation rates ranged from 1.6 Ls−1 to 11.5 Ls−1 per person with 7 out of the 10 classrooms showing ventilation rates below the recommended minimum. This study points to the need for increasing ventilation rates in classrooms.

澳大利亚维多利亚州学校教室的室内空气质量和通风监测长达一年

15 岁以下的儿童每天在学校建筑中花费超过六个小时,并且特别容易受到室内空气质量差 (IAQ) 的影响。然而,澳大利亚学校对室内环境条件的长期监测是有限的。本研究评估了维多利亚温带环境中十个澳大利亚学校教室的室内空气质量。温度、相对湿度、CO 2浓度、PM 2.5和 PM 10进行了为期一年的监测。被监测教室的温度和相对湿度值分别在 18.7°C 和 23.8°C 之间以及 44-63 RH% 之间,表明条件已经受到机械控制。10 所学校教室的平均换气 (ACH) 率差异很大(范围:0.7–4.83 ACH)。通风率从每人1.6 Ls -1到 11.5 Ls -1不等,10 间教室中有 7 间的通风率低于建议的最低值。这项研究指出需要提高教室的通风率。
