The Air Quality Index (AQI) is a standardized system used to communicate the quality of air in a specific area, reflecting the level of pollution and its potential health effects. It typically ranges from 0 to 500, with lower values indicating better air quality and higher values signifying worse conditions. The AQI is calculated based on the concentrations of various pollutants, such as particulate matter (PM), ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2). It helps inform the public about air quality and provides guidance on when to limit outdoor activities for health reasons.
Air Quality Health Index was created in 2005.
The Air Quality Index (AQI) also known as the Air Pollution Index (API) or Pollutant Standard Index (PSI)), is an indicator of air quality, based on pollutants that have adverse effects on human health and the environment.

Air Quality Index
An air quality index of 0-15 is considered good, with little to no risk to health. This level indicates that the air quality is clean and poses minimal health concerns for the general population.

During the 1970s, the air quality index in Los Angeles was often very poor due to high levels of pollution from vehicles and industry.
