—The assimilative capacity of Dawai industrial complex, located in Mynamar has been evaluated by the AERMOD air dispersion model. Maximum emission loadings of PM-10, SO2
are calculated and presented in the unit of amount per unit of time as well as amount per area per unit of time. Assimilative capacity concentration is determined by subtract the 90% of air pollution standard with the exiting measured air concentration in the study area. Then the maximum loading is calculated using those assimilative capacity values. It is found that assimilative capacity of PM-10, SO2
in this area are0.0025, 0.0031 and 0.0075 kg/ha/day, respectively. By considering the modeled results of maximum ground level concentration, it is found that dispersions of air pollutants in this study are greatly affected by complex topographical characteristic of the area.
