New Malaysia Ambient Air Quality Standard
New Ambient Air Quality Standard was established in order to replace the older Malaysia Ambient Air Quality Guideline
that has been used since 1989.
The New Ambient Air Quality Standard adopts 6 air pollutants criteria that include 5 existing air pollutants which are
particulate matter with the size of less than 10 micron (PM10), sulfur dioxide (SO2), carbon monoxide (CO), nitrogen
dioxide (NO2), and ground level ozone (O3) as well as 1 additional parameter which is particulate matter with the size of
less than 2.5 micron (PM2.5).
The air pollutants concentration limit will be strengthen in stages until 2020. There are 3 interim targets set which include
interim target 1 (IT-1) in 2015, interim target 2 (IT-2) in 2018 and the full implementation of the standard in 2020.
