ESTIMATION OF THE "NON EXHAUST PIPE" PM10 EMISSIONS OF STREETS FOR PRACTICAL TRAFFIC AIR POLLUTION MODELLING

The paper describes procedure and results of a study for Saechs. Landesamt fuer Umwelt und Geologie and for Senatsverwaltung fuer Stadtentwicklung, Berlin. It contains the results of silt load measurements of 2 streets in Germany and PM10 emission factors for these streets, deduced from curb side and background PM10- and NOx-concentration measurements. The paper presents a first proposal for Germany for an operational method to determine the "non exhaust pipe" emissions of single streets. It is a modification of the AP-42 model of the US-EPA, using as parameters location of the street (city/open country), kind of street, traffic load, average weight of a fleet vehicle, yearly number of days with rain and quality of the street surface. It is shown that the quality of the street surface might have significant influence on the PM10 emission and that the modelling is far from being satisfactory.
