Abstract: | We report and analyze data on the PM10 fraction of airborne particles measured at five recording stations in the Brussels
region from October 2002 till September 2003. These stations are representative of the various activity sectors of the Brussels
urban area. The objective was the determination of the origin of the PM10 particles (particles up to 10 μm) that are recorded
in that region in order to follow the EU directives concerning tolerance level of airborne particles concentration. In order
to evaluate the impacts of local and external factors that inject solid particles in the atmosphere of Brussels we compared
concentration data from working and not working (holidays) periods. Moreover, we also compared concentrations from periods
of agricultural activity and rest in the Brabant provinces surrounding the Brussels region for various crop types. The results
lead to the conclusion that the impact or urban traffic is rather limited while that of the agricultural activities is important.
Moreover, there appears a clear-cut distinction between different types of crops. |
