In today's industrialized world, air quality monitoring has become increasingly critical as air pollution poses significant threats to human health. To effectively monitor and improve air quality, experts analyze five key indicators: carbon dioxide (CO2), temperature and humidity, volatile organic compounds (VOCs), formaldehyde, and particulate matter (PM). This article explores their impacts on air quality and public health while providing strategies to mitigate pollution and enhance environmental conditions.
1. Carbon Dioxide (CO2) – A Double-Edged Sword
Overview:
CO2 is a colorless, odorless gas naturally present in the environment. Its sources range from fossil fuel combustion and industrial processes to human and animal respiration. In enclosed indoor spaces, CO2 concentration often rises due to limited ventilation and high occupancy.
Significance:
While low CO2 levels are harmless, excessive concentrations can displace oxygen and lead to symptoms like headaches, fatigue, and impaired focus. As a greenhouse gas, CO2 also contributes to global warming, exacerbating climate change and extreme weather events. Controlling CO2 levels benefits both human health and the environment.
2. Temperature and Humidity – Environmental Regulators for Health
Overview:
Temperature reflects air heat, while humidity measures moisture content. Both significantly affect indoor comfort and air quality.
Significance:
Optimal temperature and humidity levels support bodily functions, such as temperature regulation and respiratory hydration. However, extremes can lead to health issues like heatstroke or respiratory infections. Additionally, high temperatures and humidity facilitate the release of harmful substances like formaldehyde, increasing air pollution risks. Maintaining appropriate temperature and humidity is vital for comfort and pollution reduction.
3. Volatile Organic Compounds (VOCs) – Hidden Pollutants Indoors
Overview:
VOCs are carbon-based chemicals, including benzene and toluene, often released from paint, furniture, and building materials. Their volatility allows them to disperse easily into indoor air.
Significance:
Prolonged exposure to VOCs can cause headaches, nausea, liver and kidney damage, neurological disorders, and even cancer. Controlling VOC concentrations is crucial to safeguarding residents’ health and improving indoor air quality.
4. Formaldehyde (HCHO) – The Invisible Threat
Overview:
Formaldehyde, a colorless gas with a pungent smell, is commonly found in construction materials, furniture, and adhesives. It is a major indoor air pollutant due to its toxic and carcinogenic properties.
Significance:
Even low concentrations, of formaldehyde can irritate the eyes, nose, and throat, leading to discomfort and respiratory diseases. Monitoring and reducing formaldehyde levels are essential for ensuring safe indoor environments.
5. Particulate Matter (PM) – A Leading Air Pollutant
Overview:
Particulate matter, including PM10 and PM2.5, consists of suspended solid or liquid particles in the air. Sources include industrial emissions, vehicle exhaust, and construction activities.
Significance:
PM, especially PM2.5, can penetrate deep into the lungs and bloodstream, causing respiratory issues, cardiovascular diseases, and even cancer. Reducing PM levels is critical for health protection and visibility improvement in urban areas.
Importance of Air Quality Monitoring

- Increase ventilation or use air purifiers to reduce accumulation indoors.
05、Minimize Particulate Matter:
- Implement clean combustion technologies.
- Regulate construction site dust and road emissions.
06、Regular Air Quality Monitoring:
- Use monitoring devices to detect harmful substances promptly.
- Encourage public participation in maintaining healthy air in shared spaces.
Five Key Measures to Improve Air Quality
Improving air quality demands collective efforts, from monitoring pollutants to adopting sustainable practices. Clean air not only safeguards public health but also fosters ecological balance and long-term economic progress.
