Study Notes
Air Quality Index (AQI)
- AQI stands for Air Quality Index, a measure of air pollution levels
Purpose of Air Quality Index (AQI)
- The main purpose of AQI is to inform the public about the level of air pollutants and associated health risks
Pollutants Included in AQI
- The AQI considers five key air pollutants: ozone (O3), particulate matter (PM), nitrogen dioxide (NO2), carbon monoxide (CO), and sulfur dioxide (SO2)
Primary Sources of Air Pollution
- Primary sources of air pollution include: industrial activities, vehicle exhaust, construction, and agricultural burning
Classification of Air Pollutants
- Air pollutants are classified into two categories based on their source: • Primary pollutants: directly emitted from sources (e.g., vehicle exhaust, industrial processes) • Secondary pollutants: formed through chemical reactions in the atmosphere (e.g., ozone, particulate matter)
