The Air Quality Index (AQI) is a standardized indicator used to communicate how polluted the air currently is or how polluted it is forecasted to become. The AQI is used by government agencies to inform the public about local air quality and its potential health effects.

The AQI focuses on five major air pollutants:

​1.​Ground-level ozone

​2.​Particulate matter (PM10 and PM2.5)

​3.​Carbon monoxide

​4.​Sulfur dioxide

​5.​Nitrogen dioxide

The AQI scale ranges from 0 to 500, with higher values indicating worse air quality and greater health concerns:

​•​0-50: Good

​•​51-100: Moderate

​•​101-150: Unhealthy for sensitive groups

​•​151-200: Unhealthy

​•​201-300: Very Unhealthy

​•​301-500: Hazardous

Each category is associated with a different level of health concern, and as the AQI increases, a larger portion of the population is likely to experience adverse health effects.
