Why Indoor Air Quality Matters in Schools
Indoor air quality represents a critical yet often overlooked factor in educational environments, directly impacting student health, cognitive performance, and overall academic success. Children spend approximately 90% of their time indoors, with a significant portion of that time in school settings, making the air they breathe a fundamental consideration for educators and policymakers.
Health Implications for Students
Children are particularly vulnerable to indoor air pollutants due to their developing respiratory systems and higher breathing rates relative to their body size. The U.S. Environmental Protection Agency emphasises that poor indoor air quality can trigger a range of health issues, including increased respiratory problems, higher rates of asthma attacks, and greater susceptibility to infectious diseases.
Research from the International Journal of Environmental Research and Public Health reveals that students exposed to suboptimal air quality experience more frequent health symptoms such as headaches, fatigue, and respiratory irritations. These health challenges directly translate into reduced academic performance, higher absenteeism, and diminished learning capacity.

Beyond immediate health concerns, indoor air quality profoundly influences cognitive function and academic achievement. Studies have demonstrated that students in well-ventilated classrooms with superior air quality exhibit enhanced concentration, improved test scores, and better overall cognitive performance.
Key factors affecting indoor air quality in schools include:
- Ventilation Systems: Inefficient air circulation can trap pollutants and increase indoor contaminant concentrations.
- Building Materials: Older school buildings might contain asbestos, lead-based paints, or other harmful substances.
- External Pollution: Proximity to industrial areas or high-traffic zones can introduce additional air quality challenges.
Investment in comprehensive indoor air quality management is not merely a health intervention but a strategic approach to optimising educational outcomes. Schools that prioritise air quality create environments conducive to learning, student well-being, and long-term academic success.
Addressing indoor air quality requires a multifaceted approach involving regular monitoring, strategic ventilation improvements, appropriate filtration systems, and ongoing maintenance. Educational institutions must recognise that clean air is fundamental to creating supportive, healthy learning environments that enable students to thrive academically and physically.
Common Sources of Indoor Air Pollution in Schools
Indoor air pollution in schools emerges from a complex network of sources that can significantly compromise the health and learning environment of students and staff. Research from the National Library of Medicine highlights the multifaceted nature of these pollutant sources, which range from building materials to daily classroom activities.
Below is a table summarising the main sources of indoor air pollution in schools, along with examples and their typical pollutants. This table aims to help readers quickly identify where air quality threats may arise in educational settings.

Building and Construction Materials
School infrastructure itself can be a primary contributor to indoor air quality challenges. Older school buildings often contain materials that continuously release harmful chemical compounds. Asbestos in aging infrastructure, lead-based paints, volatile organic compounds (VOCs) from flooring and wall materials, and formaldehyde in pressed wood products create ongoing air quality risks.
Modern construction materials are not exempt from scrutiny. New furniture, carpets, and synthetic building components can off-gas chemicals for extended periods, introducing potentially hazardous substances into the school environment. These materials release microscopic particles and chemical emissions that can accumulate over time, creating a persistent indoor air quality challenge.
Classroom Activities and Equipment
Everyday educational activities contribute significantly to indoor air pollution. Science laboratories with chemical reagents, art rooms with solvents and adhesives, and printing equipment generate substantial airborne contaminants. Cleaning products, disinfectants, and maintenance chemicals further compound these pollution sources.
