AQI provides a simple, uniform way to report daily air pollution concentrations,to tell the public about ways to reduce air pollution(associated)with these concentrations, and to describe some general precautionary steps that can be taken. AQI is a reporting tool that converts the pollutant concentrations measured in a community’s air to a simple number on a scale of 0 to 500. Intervals on the AQI scale are related to the potential health effects of the daily measured concentrations of five major pollutants: carbon monoxide (CO), ozone O3, nitrogen dioxide (NO2), sulfur dioxide (SO2) and  particulate matter. The intervals and the terms describing the air(quality)levels are:

Value
