Today, air pollution in developing countries, has imposed a significant negative effects on public health and the environment. Box model is among the techniques that are used for modeling and predicting of air quality. Box model is widely used in modeling of air pollution. In this paper, after collecting the necessary information from analyzing the chimneys of an industrial plant located in south west of Iran, predictions of the pollution distribution of CO gas was analyzed by the air box model. The formula of box model was estimated by Excel 2013Microsoftsoftware in 20 zones and 14 hours, and by entering the information, three-dimensional graph height, time and zone were obtained. It should be noted that if the selected times and zones are divided into smaller intervals, the accuracy of the estimation of pollution concentration in this model increases. The results showed that by the stability of air and reduced the volume of element, the accuracy prediction increases and the pollution of the industrial plant goes to towards the city. Contamination concentration (CO) after passing through the first zone of the city gradually decreases to the boundary that the concentration will be the same in all zones.
