A photochemical dispersion model has been used to calculate concentrationlevels for an area covering the Netherlands and its surroundings during a given episode. The agreement between measured and calculated concentrations of O3, and to a somewhat less extent of NO2, showed to be remarkably good. With this model the influence of traffic emissions, the emissions from industry and the inflow of emissions from outside the area during the episode considered on the existing concentration levels of O3, NO2 and NO has been determined. The emissions from outside the area showed to have a large influence on the O3-concentrations. The influence of industry on O3- and NO2-levels is larger than that of traffic.The model has proven to be a valuable tool in determining the influence of different source categories and control regulations on the concentration levels.
