Abstract
This research is being done to investigate the physical- and chemical properties of
airborne particulate matters (PM) from Nibong Tebal and Parit Buntar. Non~reactive
carbon layer is glued onto a stub to collect airborne particulate matters from the.
atmosphere. The st'ub was exposed to the ambient atmosphere for 24 hours to allow
the particulate matter to deposit onto it. PM sample from vehicles exhaust also being
collected and analyzed in order to see the association between the vehicles as a source
of particulate matter. The stubs then are placed directly into the Scanning Electron
Microscope (SEM) to analyze their images. Chemical compositions of those
particulate matters are being analyzed by using Energy Dispersive X-ray equipment
that is presences as an accessory to the SEM. The electron microscope (SEM) used
was a Leo Supra 50 VP while Energy Dispersive X-ray equipment used was Oxford
Inca 400. From the research~ it was found that the greatest contribution to particulate
matters mass collected in Parit Buntar and Nibong Tebal are carbon (organic carbon
or/ and elemental carbon), 0, AI, Si and other species such as Ca, K, Fe and Mg.
These elements probably come from earth crust mineral and particles from vehicles
exhaust as well as fact~rie~n.~arby ..WhileJhe .size is varies from 7.9 ~m to 158 Jlm
-·and can be· categorized as coarse particles.
