Abstract
Recently, air pollution is one the most important issues of concern to the public. The growth in industrial areas directly increases the traffic density of that area. Hence it will increase the air pollution particularly PM10. This research investigates the concentration of PM10 for year 2006 and 2007 in five different areas that includes industrial, residential and background. SPSS and WRPlot view software were used to obtain the descriptive statistics and wind distribution for each station. From the descriptive statistics, Nilai station records the highest concentration for both years that is 231.750 µg/m3 in 2006 and 123.580 µg/m3 in 2007. It was found that industrial areas have contributed to the highest concentration on PM10. The comparison between each industrial station with background and residential station also shows the similar findings. From time series result, both three industrial stations show the peak value especially during 2006. This is due to short period of haze event in 2006, which affects the air quality during that year. Many factors influence PM10 concentration in the
atmosphere. One of the main factors is seasonal variations. Mostly, maximum concentration and highest peak occur during southwest monsoon due to dry weather period. From the wind distribution, the possible sources of pollutant were determined. Industrial areas were the major sources of pollutant, followed by emission from vehicles, power plant and open burning activities. Based on the analysis, Perai station shows the lowest concentration compared to Nilai and Pasir Gudang. Hence, it was proposed to be the reference station for industrial area.
