Sources of Indoor Air Pollution

Understanding sources of indoor air pollution is critical for maintaining a healthier indoor environment. Identifying these sources allows for effective mitigation measures to improve air quality and minimize potential health hazards associated with indoor air pollution.

Common Indoor Pollutants

• Volatile Organic Compounds (VOCs): Emitted from paints, cleaning products, and building materials.
• Particulate Matter (PM): Fine particles from smoke, cooking, or outdoor sources.
• Carbon Monoxide (CO): Produced by combustion appliances, such as gas heaters or stoves.
• Radon: A radioactive gas naturally occurring in soil and can enter homes through cracks or openings.
• Nitrogen Dioxide (NO2): Released from gas stoves, fireplaces, and vehicle exhaust.
• Formaldehyde: Found in materials like pressed wood and insulation.
