What is the purpose of the Air Quality Index (AQI) in public health practice?

Explanation:
AQI communicates health risk from air pollution in a simple, actionable way. It combines readings from multiple pollutants into a single, easy-to-interpret index, typically shown with color codes that range from good to hazardous. This translation lets public health practitioners issue timely alerts and guidance, helping people—especially vulnerable groups—adjust outdoor activities and take protective actions to reduce exposure. Because it covers several pollutants, it gives a fuller picture than focusing on any one pollutant. It is not a measure of water quality or noise, nor is it limited to ozone alone.
