Reduktionspotenziale verkehrsbeschränkender maßnahmen in Bezug zu meteorologisch bedingten schwankungen der PM₁₀- und NO _x-immissionen

Potential reduction of PM₁₀ and NO_x immissions through traffic restrictions in comparison to variations caused by meteorological conditions

Summary, in English

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 NO_x 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.
