Abstract

Context: Indoor air pollution (IAP) affects the long-term health, cognitive growth, and academic performance of children. Since children spend most of their time at school, quantifying IAP in classrooms is an important parameter for air pollution.

Aim: To assess the average particulate matter (PM) levels inside and outside of classrooms along with their associated factors and teacher's perceived indoor climate.

Setting and design: Cross-sectional survey in nine government-run schools.

Methods and material: PM_2.5 and PM₁₀ were measured inside the classroom and outdoors simultaneously during summers, using an Atmos monitor for two consecutive days, along with several school and classroom characteristics. Perception about indoor air quality was captured from teachers (n = 15) using a validated questionnaire.

Statistical analysis: Mean values of PM using mixed effect linear regression. Perceived indoor air quality is presented using percentages.

Results: Mean indoor PM_2.5 and PM₁₀ was 52.5 µg/m³ and 65 µg/m³. Indoor and outdoor PM levels were highly correlated, but the indoor-outdoor ratio of PM concentrations was more than 1. Teachers were mostly bothered by dust, dirt, and noise in the schools.

Conclusion: Indoor air quality was higher than World Health Organization (WHO) standards but within the national standards. Need further research to find the exact cause for higher indoor PM levels compared to outdoor PM levels.

印度恰蒂斯加尔邦比拉斯普尔区公立学校室内颗粒物质和教师感知室内气候的评估：一项横断面研究。

背景：室内空气污染（IAP）会影响儿童的长期健康、认知成长和学习成绩。目的：评估教室内外的颗粒物（PM）平均水平及其相关因素和教师感知的室内环境：在九所公立学校进行横断面调查：方法：使用 Atmos 监测器在夏季连续两天同时测量教室内外的 PM2.5 和 PM10，以及学校和教室的一些特征。统计分析：可吸入颗粒物的平均值采用混合效应线性回归法。结果：结果：室内 PM2.5 和 PM10 的平均值分别为 52.5 µg/m3 和 65 µg/m3。室内和室外的可吸入颗粒物浓度高度相关，但室内和室外的可吸入颗粒物浓度比大于 1：室内空气质量高于世界卫生组织（WHO）的标准，但在国家标准范围内。需要进一步研究，找出室内可吸入颗粒物浓度高于室外可吸入颗粒物浓度的确切原因。
