AIR POLLUTANT INDEX (API)

3

Air Pollutant Index (API) is an indicator for the air quality status at anyparticular area

It is calculated based on 5 major air pollutants which are:

Sulphur Dioxide, SO2 Nitrogen Dioxide, NO2 Carbon Monoxide, CO

Particulate Matter With Diameter < 10 micron, PM10

Ground Level Ozone, O3

The air pollutants concentration are measured by 52 automatic airquality stations throughout Malaysia
