Ambient air concentrations of particulate matter from passenger cars.
Using our measurement results on particulate emissions from passenger cars we have calculated ambient air concentrations for various US and European scenarios. This was carried out with the help of mathematical dispersion models for different traffic situations including street canyons and motorways. We have been very conservative in our choice of the scenarios, i.e. we have always used situations in which there are very high stress levels (e.g. constantly high traffic flow instead of average traffic flow). Finally, the thus determined air concentrations are compared with the corresponding air quality standard available from the literature.
