Abstract

A study was carried out to model the dispersion of NOx and PM10 concentration from the point sources at KKIP by using the ISC-AERMOD View dispersion model. In this study, there are 7 locations as sensitive receptors were defined within the 1500m x 1500m area surrounding the SESB power plant and ARL power plant. The contour 20 map of the dispersion in NOx and PM10 showed uneven trends of circular which is mainly headed to the north and south region due to the wind blows in multi-direction and caused by the southwest wind dominant. From the combined of 3 stacks, the maximum concentration of NOx was recorded 73.75 µg/m3 at distance of 0.075 km to the northwest of SESB power plant in 24-hr averaging while the maximum concentration of PM10 is 56.87 µg/m3 at the distance of 0.335 km to the northwest of ARL power plant. While for the single source of SESB power plant in NOx and PM10 is 70.84 µg/m3 and 49.99 µg/m3 of maximum ground level concentration, for ARL power plant the maximum ground level concentration of NOx and PM10 is 1.42 µg/m3 and 1.41 µg/m3 respectively. Among seven receptors, the highest ground level concentration predicted of NOx and PMlO was 55.02 µg/m3 and 32.47 µg/m3 at the Polytechnic KK. The single point source that contributed the largest amount of NOx and PM10 was from SESB power plant. The statistical analysis between predicted concentration and the measured data of NOx and PM10 showed strong correlation with r-value of 0.966 and 0.965 and r² value of 0.933 for NOx and 0.931 for PM10. The study result revealed that the NOx and PM10 emitted from the point sources in KKIP were well and not exceeded the limit of Malaysia Ambient Air Quality Guideline. Therefore, the emission of both pollutant from the SESB power plant and ARL power plant did not harmful to public health and no adverse impacts or effects to the surrounding area. The receptors that exposed to higher concentration of both pollutant should take implementation and prevention steps.
