Abstract

This paper presents an air quality study in an urban traffic hot-spot in Lisbon, Portugal, by comparing the atmospheric pollutant concentrations obtained by a numerical model with measured values. Results indicate that the mean variation of particle and gaseous concentrations followed the traffic flow rate, evidencing the occurrence of PM10 concentrations greater than the respective air quality limit. SO2 and CO results fulfil the national legislation. The performed simulations showed that current methodologies for PM10 dispersion modelling allow to obtain acceptable results on air quality assessment within complex urban areas.
