POLLUTANT DISPERSION MODELLING WITH OSPM IN A STREET CANYON FROM BUCHAREST

摘要

In urban areas, where the population is very numerous and the traffic is relatively high, the exposure of people to the traffic related concentrations is significant. The aim of this study is to evaluate the predictions derived from the Danish Operational Street Pollution Model (OSPM) when the input data are obtained by simple measure methods. Pollution concentrations, temperature, flow and turbulence conditions were measured in Bucharest, Bd. Dacia, for different periods of year. The background concentrations ware obtained using the OML model. Measurements are compared to model results which reproduce reasonably well the observed distribution of pollutants in the street. The results indicate that the OSPM data might be useful in assessing long-term exposure to air pollutants in epidemiological studies.
