Although Beijing was not ranked in this list, it still averaged air pollution (29.89μg/m3) levels more than twice the recommended limit.

How Air Pollution Was Measured

There are various pollutants (both particles and gases) that can be found in the air. One of the most commonly tracked pollutants are very small, fine particles called PM2.5.

These small pollutants are under 2.5 micrograms in width and considered to be one of the more dangerous pollutants due to their ability to enter deep into the lungs and bloodstream. 

Recommended limits

The limit that is closely aligned to what studies show about the health effects of pollution is the annual limit of 10 micrograms/m3
