Abstract
In this study, the level of NO, and SO2 concentrations in the surrounding areas of
Serdang Power Station have been calculated using ISCST3 dispersion model.
The 256 grids defined in area of 22km x 22km are accepted as receptor grids and
the contribution of emission ffom the existing Serdang Power Station has been
used as an input data. The maximum 1-hr averaging ground level concentration
of NOx and SO2 predicted by the model are 134.17 &m3 and 159.31 pg/m3 at
distance of 1.5 km southeast of the plant. However, these levels are well within
the Malaysian Ambient Air Quality Standards 1990 and the World Health
Organisation (WHO) Guidelines 1999. The model was validated by comparing
the model output and actual field measurement with 95% of the accumulative
frequency distribution by a factor of less than 2. Results of the study revealed
that the air pollution disper
