Monthly Air Quality


Particulate matter (PM-10) is a fraction of the Total Suspended Particulate with an aerodynamic diameter less than or equal to 10µm. These particles are measured in ambient air using the Tapered Element Oscillating Microbalance (TEOM) System. Measurements are made at seven sites by the MetMalaysia, namely, Petaling Jaya, Tanah Rata (Cameron Highlands), Kuching, Kuantan, Senai, Bayan Lepas and Kota Kinabalu.  The average daily PM-10 level recommended in the Malaysian Ambient Air Quality Guidelines for PM-10 is below 150.0mg/m3. Concentration of PM-10 above 150.0µg/m3 in 24 hours is considered unhealthy to humans. The reports for PM-10 concentrations recorded at five selected stations in June 2017 are given below.
