The atmospheric dispersion of pollutants characterizes the evolution in time and space of an ensemble of particles (aerosols, gases, dust) emitted into the atmosphere. This report explores the impact of cow farm on the atmosphere and aims to provide practical suggestions which could be easily monitored on how to reduce or eliminate any identified negative environmental effects. The study attempts to assess the emissions of pollutants (CH4 and NH3) in the atmosphere at cow farm, located in the village Garbova, the Alba county, and their atmospheric dispersion modeling using AERMOD program, developed by the American Meteorological Society in collaboration with the Environmental Protection Agency the United States. The study has shown that the volume of gases emitted have no significant impact on nearby communities . The results, measured in terms of average concentration of the pollutants at ground level show that such concentrations are below the limits established by current Romanian legislation. It can be concluded that AERMOD program can provide useful information to identify high pollution impact areas. Therefore, air dispersion model is an easy way used for simulation and assessment of directions and concentrations of air pollutants exposure to the environment
