Abstract:
An important component of air quality management and health risk assessment is improved understanding of spatial and temporal variability in pollutant concentrations. The aim of this paper is to assess the concentration levels of PM10 in a few urban sites in Bucharest, Romania. The key influences on the causes of high concentrations of pollutants include traffic characteristics but also meteorology, which affects the dispersion of emissions. Therefore, the analysis of the measured concentrations was related to traffic and meteorological conditions. The direct contribution of the traffic relative to the contribution from urban background was studied. The study has been performed for winter and summer seasons. The measurements shown that the highest NOx, SO2 and particulate matter (PM10) concentrations occur in the winter and summer periods, due to unfavourable meteorological dispersion conditions. Generally, the results show that the road traffic is the main contributor when the NOx. For the PM10 both the traffic and resuspension of road dust are important. This type of study of spatial and temporal variability of pollutant concentrations allows evaluating the requirements of air quality models to represent the key effects.
