This paper was aimed to determine the level of particulate matter that satisfies the requirements of Malaysia Ambient Air Quality Guidelines (MAAQG) and World Health Organization (WHO), which includes the tracing of the concentration of heavy metal in dust samples. The study of ambient air quality was conducted at Aman Perdana, Klang, Selangor, Malaysia where the sampling of each size of the PM10, PM2.5 and PM1 was conducted within three days in order to determine the concentration levels. However, the sampling of PM10 was conducted over a period of five months to determine the concentration pattern. The dust sampling was conducted to trace and determine the concentration of heavy metal in the dust. Element of heavy metal was chosen based on the first batch sample screening namely Aluminium, Arsenic, Calcium, Cadmium, Chromium, Iron, Potassium, Magnesium, Nickel, Lead and Zinc. Methodically, the dust samplings, filter digestion and tracing heavy metal were determined by using the Real Time Aerosol Monitoring System (E-Sampler), Milestone Microwave Laboratory System (ETHOS Touch Control) and Inductively Coupled Plasma Optical Emission Spectroscopy (Perkin Elmer Optima 7300 DV) respectively. The values of PM10, PM2.5 and PM1 are within the ranges of 55µg/m³ and 25µg/m³, 42µg/m³ and 20µg/m³, and 42µg/m³ and 20µg/m³ inclusive, respectively. The analysis, which reflects the important step forward in the evaluation of environmental quality, reveals that on average, concentration of the three types of aerodynamic sizes is below the permissible limit of MAAQG, however, several data exceeded the maximum allowable limit of the World Health Organization (WHO, 2005), for examples, Calcium was recorded with higher concentration of 86ppm and the lowest is Zinc 0.5ppm.
