Recently, because of the regulatory enhancement together with the technology development, concentration of pollutants in emission sources are decreasing significantly. The Nox concentrations at stack gases are almost lOppm and sometimes less than that for facilities constructed in city areas. Therefore, the concentrations at emission source are less than one hundred times and for some cases less than ten times of ambient concentration. The ventilation towers for automobile tunnels in urban areas are typical examples. For such kind of sources, particularly nitrogen oxides dispersion usual plume dispersion model assuming inactive gases are not suitable, since the dispersion and chemical reactions took place together in the atmosphere. We developed An Integrated Plume Dispersion Model of Nox with chemical reaction and examined the performance of the model.
