【 摘 要 】

This research aims to study the possibility of using AERMOD air quality model to estimate the air pollutant levels of a selected city - Nakhon Ratchasima Municipality, Thailand. Four pollutants were studied: PM10, CO, SO2, and NOx. The measurement data were obtained from a PCD automatic pollutant monitoring station for comparison with the model's results. The air pollution sources used were residential, furnace, traffic and industrial sources. Emission factors were used to estimate the concentration of pollutants from the activities of the population in the area. The estimation was based on the Top Down Approach method (TDA). Results shows that the pollutant concentrations obtained from the model were lower than the measurement values in all parameters. The values obtained from the model were 4.14% to 77.88% of the measurement values. The cause may be due to incomplete account of sources. However, the model can be useful for assessing the carrying capacity of the urban area.
