What is the standard of air index? What is IAI air index?

The air index, also known as the air quality index or air pollution index, simplifies the concentrations of several air pollutants that are routinely monitored into a single conceptual index value based on ambient air quality standards and the impact of various pollutants on human health, ecology, and the environment. The following mainly shares the standards of the air index, which I hope will be useful to you.

What is the standard of air index?

The standards of the air quality index are: 0-50, 51-100, 101-200, 201-300 and greater than 300, which correspond to the pollutant concentration limits of the national air quality standards for daily average values ​​of Level I, Level II, Level III, Level IV and Level V. In practical applications, Level III and Level IV are further divided into Level III (1), Level III (2) and Level IV (1), Level IV (2). Level I, the air quality is assessed as excellent and has no impact on human health; Level II, the air quality is assessed as good and has no significant impact on human health; Level III, is light pollution, and healthy people experience irritation symptoms; Level IV, is moderate pollution, and healthy people generally experience irritation symptoms; Level V, is severe pollution, and healthy people experience severe irritation symptoms.

What is the IAI Air Index?

The air index, also known as the air quality index or air pollution index, simplifies the concentrations of several conventionally monitored air pollutants into a single conceptual index value based on ambient air quality standards and the impact of various pollutants on human health, ecology, and the environment. It represents the degree of air pollution and air quality in a graded manner, and is suitable for representing the short-term air quality status and changing trends of cities.

The range of the air pollution index is set at 0-500, of which 0-50, 51-100, 101-200, 201-300 and greater than 300 correspond to the pollutant concentration limits of the national air quality standards for daily average values ​​of Level I, Level II, Level III, Level IV and Level V. In practical applications, Level III and Level IV are further divided into Level III (1), Level III (2) and Level IV (1), Level IV (2). Level I, the air quality is assessed as excellent and has no impact on human health; Level II, the air quality is assessed as good and has no significant impact on human health; Level III, is light pollution, and healthy people experience irritation symptoms; Level IV, is moderate pollution, and healthy people generally experience irritation symptoms; Level V, is severe pollution, and healthy people experience severe irritation symptoms.

How much air index is not suitable for running?

The Air Quality Index is a quantitative indicator of air quality.

Generally, air quality below 50 is excellent, 100-50 is good, 100-150 is lightly polluted, 150-200 is heavily polluted, and above 200 is severely polluted.

The lower the air quality index, the more suitable it is for outdoor sports. Generally speaking, the more suitable air quality index is below 100. If the air quality index reaches above 150, it is best not to do outdoor sports.
