The increase in urbanization and the growth of industrialization is a result of modern life, but this phenomenon also creates the problem of air pollution. Today, air pollution has reached such dimensions that it has a global impact, not only locally and regionally. Since air pollution constitutes a great risk for human health, air quality has become an issue that the whole world attaches importance to. Many domestic and foreign organizations are working to solve air pollution problems and determine strategies in this direction.
A classification system called the Air Quality Index is now widely used all over the world. This system classifies air quality as good, medium, bad or dangerous depending on the concentration of pollutants in the air. The methods and criteria used to calculate this index in various countries have been determined in accordance with the countries' own air quality standards. The Air Quality Index uses different definitions and colors in certain categories and is regulated separately for all pollutants measured. In our country, National Air Quality Index has been prepared by adapting to national legal regulations and limit values. This index determines air quality based on five main pollutants: particulate matter (PM10), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2) and ozone (O3).
The following table shows the internationally accepted index values and criteria:

Meaning |
|
0 - 50 |
Good |
Green |
Air quality is good, air pollution is risk-free or less risky |
|
51 - 100 |
Medium |
Yellow |
Air quality is appropriate, but for sensitive people some pollutants may occur at moderate levels of health concern |
|
101- 150 |
Sensitive |
Orange |
Health effects may occur for vulnerable people, but generally not likely to affect |
|
151 - 200 |
Unhealthy |

Anyone can have health problems, can have serious health effects for vulnerable people |
|
201 - 300 |
Bad |
Purple |
Health emergency, everyone is likely to be affected |

301 - 500 |
Dangerous |
Brown |
Health alarm, everyone at more serious health risk |
