On human health they cause cancer and also promote respiratory diseases. These problems have become in recent years a permanent concern for scientists, public authorities and even civil society. It is in this context that our ends study. We are more particularly interested in the modeling of atmospheric pollution at the localscale of a power plant (case of a chimney) as well as the influencing factors. this dispersion.frpollution, atmosphere, dispersion, concentration, gaseouspollutants, dispersion model.pollution, atmosphère, dispersion, concentration, polluants gazeux, modèle de dispersionThesis
