Sammanfattning

The health limit values for PM10 concentration which are presently in force cannot be met on many heavily polluted streets in German conurbations. Soot filters, bans on motorised traffic during certain time periods and areas or for specific vehicle classes, speed limits and other measures are meant to lead to a substantial reduction of the pollution. This article compares the effects of the mentioned reduction measures to variations caused by meteorological conditions. The investigation is based on a comprehensive analysis of data sets recorded in the German state of Baden-Wurttemberg. Methods of data screening are used to show that the PM 10 load is largely determined by meteorological conditions, which is not the case for NOx immissions. Site conditions are of particular importance for the interpretation of measured PM10 concentrations, i. e., the local exchange of air, the conditions for the disposition of particles as well as the resuspension. Nitrogen oxides may be significantly reduced by local traffic restrictions, whereas the reduction potential with regard to particulate matter concentrations is rather low.
