Air Pollution Index
open-in-new
<p> The Air Pollution Index is a simple and generalized way to describe the air quality, which is used in <a href="/facts/Malaysia/8zbUMzCP">Malaysia</a>. It is calculated from several sets of air pollution data and was formerly used in <a href="/facts/Mainland_China/HFXJcUky">mainland China</a> and <a href="/facts/Hong_Kong/4nAf3mqQ">Hong Kong</a>. In mainland China the API was replaced by an updated <a href="/facts/Air_quality_index/VY02cUut">air quality index</a> in early 2012 and on 30 December 2013 Hong Kong moved to a health based index. </p>
