What is AQI
AQI is a measure of the concentration of certain air pollutants in the air.
These pollutants include particulate matter (PM2.5 and PM10), ozone, nitrogen dioxide, and sulfur dioxide.
The AQI is calculated using a formula that takes into account the concentrations of these pollutants and their potential health effects.
The higher the AQI, the more polluted the air and the greater the health risk.
People with respiratory problems, such as asthma, are especially sensitive to the effects of air pollution.
AQI range
Good (0-50): Green
Moderate (51-100): Yellow
Unhealthy for Sensitive Groups (101-150): Orange
Unhealthy (151-200): Red
Very Unhealthy (201-300): Purple
Hazardous (301-500): Maroon
The AQI is used to inform the public about the quality of the air in their area.
The AQI is calculated by government agencies and is available to the public on websites and mobile apps.
