The increasing importance of understanding the structure of Air Pollution
Index (API) makes it necessary to come out with a compositional of API based
on its pollutants. This will be more comprehensible for the public and easier to
cooperate with authorities in reducing the causes of air pollution. Since five
pollutants contribute in determining the API values, API can be shown as a
compositional data. This study is conducted based on the data of API and its
pollutants collected from Klang city in Malaysia for the period of January 2005
to December 2014.
