 Introduction

The adverse health effects of air pollution from traffic are well known, especially the health effects of particles. In the new EU directives on ambient air quality the limit values of particles have been strengthened significantly. The limit values have been set for PM10/PM2.5, but all new investigations have indicated close relationship to the smallest particles. The aim of the present study is to quantify the emissions of ultrafine particles from diesel and petrol vehicles and include the results in models of exposure estimates. Preliminary results are shown in the poster.
