室内空气质量(IAQ)和室内空气污染是影响城市环境的关键问题。显著影响生活质量。如今,不良的IAQ与呼吸系统和心血管疾病有关,过敏反应,和认知障碍,特别是在教室之类的环境中。因此,这项研究调查了一年多的室内环境质量对大学教室学生健康的影响,使用各种传感器测量19个环境参数,包括温度,相对湿度,CO2、CO、挥发性有机化合物(VOCs),颗粒物(PM),和其他污染物。因此,这项研究的目的是分析室内小气候对在教室工作的个人健康的影响,以及它对教育成果的影响。数据揭示了甲醛(HCHO)国际标准的频繁超标,VOC,PM2.5,NO,和NO2。HCHO和VOCs水平,通常源于建筑材料和课堂活动,特别高。PM2.5水平超过年度和每日标准,而NO和NO2水平,可能受到通风不足的影响,也超过了建议的限制。尽管有许多现行国际标准的超标,室内小气候质量指数(IMQI)得分表明室内环境总体良好,该指标大多在0到50之间。此外,分析表明,一些指标很有可能超过现行标准,它们的价值预计在未来会呈上升趋势。该研究强调了教室需要更好的通风和污染物控制,以确保健康的学习环境。污染物标准的频繁超标可能会对学生的健康和学习成绩产生重大影响。因此,本研究强调了持续监测和积极措施以维持最佳室内空气质量的重要性。
Indoor air quality (IAQ) and indoor air pollution are critical issues impacting urban environments, significantly affecting the quality of life. Nowadays, poor IAQ is linked to respiratory and cardiovascular diseases, allergic reactions, and cognitive impairments, particularly in settings like classrooms. Thus, this study investigates the impact of indoor environmental quality on student health in a university classroom over a year, using various sensors to measure 19 environmental parameters, including temperature, relative humidity, CO2, CO, volatile organic compounds (VOCs), particulate matter (PM), and other pollutants. Thus, the aim of the study is to analyze the implications of the indoor
microclimate for the health of individuals working in the classroom, as well as its implications for educational outcomes. The data revealed frequent exceedances of international standards for formaldehyde (HCHO), VOC, PM2.5, NO, and NO2. HCHO and VOCs levels, often originating from building materials and classroom activities, were notably high. PM2.5 levels exceeded both annual and daily standards, while NO and NO2 levels, possibly influenced by inadequate ventilation, also surpassed recommended limits. Even though there were numerous exceedances of current international standards, the indoor
microclimate quality index (IMQI) score indicated a generally good indoor environment, remaining mostly between 0 and 50 for this indicator. Additionally, analyses indicate a high probability that some indicators will exceed the current standards, and their values are expected to trend upwards in the future. The study highlighted the need for better ventilation and pollutant control in classrooms to ensure a healthy learning environment. Frequent exceedances of pollutant standards can suggest a significant impact on student health and academic performance. Thus, the present study underscored the importance of continuous monitoring and proactive measures to maintain optimal indoor air quality.
