The smaller particles that dominate the particle number concentration (PNC)
in the ambient air only contribute to a small percentage of particulate matter
(PM) mass concentration although present in high particle number
concentration. These small particles may be neglected upon assessing the
health impacts of the PM. Hence, the knowledge on the particle number
concentration size distribution deserves greater attention than the particulate
mass concentration. This study investigates the measurement of the particle
mass concentrations (PM2.5) and PNC of 0.27 ?m < Dp < 4.50 ?m during the southwest (SW), inter-monsoon (IM) and northeast (NE) monsoons in the industrial-residential airshed of Skudai, Johor Bahru, Malaysia.
