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:

Air Quality Index
Levels of Health Concern
Good 0-50 Air quality is considered satisfactory, and air pollution poses little or no risk.
Moderate 51-100 Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
Unhealthy for
Sensitive Groups
101-150 Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Unhealthy 151-200 Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
