Abstract
Particulate matter is a dominant air pollutant in Malaysia and it is a major emission that has caused many respiratory problems. In this study the influence of trace gases and meteorological parameters with particulate matter that has an aerodynamic diameter of less than 10 m (PM‚�‚) were investigated. Simple linear regression was used to analyse the strength of trace gases and meteorological parameters with PM‚�‚ while the Principal Component Analysis (PCA) was used to determine the sources of air pollution. The average concentration of PM‚�‚ for a year (January 2010 to December 2010) in Pasir Gudang was 56.567 g/m which exceeded the New Ambient Air Quality Standards and international guidelines. The highest mean daily was recorded at 9 a.m (LT) (63.644 g/m) while the lowest was at 11 p.m. (LT) (31.44 g/m) (12-60 g/m). PM‚�‚ concentrations are significantly correlated with SO‚‚ (R0.0302 p0.01) CH‚„ (R20.0817 p0.01) RH (R 0.0581 p0.01) NOx (R0.1118 p0.01) and NO (R0.0786 p0.01). The major sources of PM‚�‚ are traffic combustion at 35.505 followed by meteorological factors at 28.972 and traces gases from industry such as SO‚‚ and NOx at 11.009.
