The tapered element oscillating microbalance (TEOM) is one of utilized instrument to
measure ambient particulate matter concentrations used by Department of
Environment Malaysia to measure particles concentration across country. In this study,
an experimental set-up were at 2 Continuous Air Quality Monitoring (CAQM) stations
(Kuala Terengganu and Kota Bharu stations) for 4 consequent days by using TEOM
and DustTrak DRX 8533. The open-source software “R” and associated packages were
used to anlaysed the data. Measurements of particulate matter made with a TEOM
were found to be lower than DustTrak (DRX). It was found that high concentration of
PM10 and PM2.5 with over 30% average differences between these instruments were
indicated through-out this study. Lower relationship with R 2 between 0.20 - 0.30 were
found which indicated weak correlation were indicated. Other factors such as lagging
time and the effects of meteorological parameters to the concentrations of particulate
matter were also observed.
