air quality index (aqi)

The air quality index (AQI) is a measurement that categorizes the level of air pollution in a specific area. It provides a clear indication of the quality of the air based on various pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. The AQI scale typically ranges from 0 to 500, with higher numbers representing worse air quality. The index helps individuals and governments understand the potential health risks associated with the air they breathe and make informed decisions regarding outdoor activities and pollutant control measures.
