Abstract: The objective of this study was to simulate carbon monoxide (CO) dispersion exited from the stacks of a cement industry in Doroud, Iran by Gaussian Model (GM). Four sampling period was conducted for the measurement of CO from the factory's three-stack flow during a period of one year. The input parameters were the rate of CO emission, meteorological data,  factors related to the stack, and factors related to the receptor. Parameters were incorporated in the model and the dispersion of CO during a period of four season was modeled.The southwesterly winds have dominated for the past five years. The highest and the lowest CO levels were estimated at spring and fall seasons with maximum amount of 842.06 and 88.31 µg/m3 within distances of 526 and 960 m away from the cement plant, respectively. Althoughthe maximum predicted CO concentration at four seasons were lower than the NAAQS standard,the simulation results can be used as a base for reduction of CO emissions rate, because the long-term exposure to emissions of cement plant imposes potentially significant health and environmental impacts.
