The objective of our study was to simulation of carbon monoxide (CO) dispersion exited from the stacks of a cement industry of Doroud, Iran by Gaussian Model (GM). Four sampling period was conducted to measurement of CO from the factory's three-stack flow during one year. The input parameters for were the rate of CO emission, meteorological data, factors of related to the stack, and factors of related to the receptor. Parameters were corporate and the dispersion of CO during four season was modeled. The southwesterly winds were dominated during recently five years. The highest and the lowest CO levels were estimated at spring and fall seasons with maximum amounts of 842.06 and 88.31 µg/m3 within distances of 526 and 960 m away from the cement plant, respectively. Although, the 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.
