Abstract
Numerical modelling was used to study the impact of urban air pollution from Setúbal City intwo important natural reserves. Setúbal is a city in the middle south Portugal with a large residentpopulation, important industry and intense traffic activities. There is an important harbour, which isresponsible for intense heavy vehicle traffic. Setúbal is surrounded by two natural reserves, a mountain(Arrábida) and a river delta (Sado River). There is also an important tourist zone near Setúbal withimportant beaches and tourist activities. The main pollutants considered in this study were SO2, Particles,NOx, CO, and VOC. A range of numerical models there was used to produce results. The AMDS-Urbanmodel was used for the pollutants dispersion, the FLOWSTAR model for the meteorological conditions andthe MOBILE 6.0 to estimate traffic emissions. One database was made containing information aboutindustry emissions and other emissions in the city. It was also used a geographic information system.Numerical modelling was done considering all models and information coupled and numerical simulationswere produced for different emissions and meteorological conditions.This numerical approach can be successfully applied to other cases to study the impact of urban airpollution. The tourist zone is the most affected by the urban air pollution but both reverses can also beaffected manly depending on the meteorological conditions which are mostly depending on the seasonally.This work has been developed with the financial support of the Fundação para a Ciência e Tecnologia andFEDER under Sapiens Programme (project nº POCTI/MGS/47247/2002).
