Summary

The health impact of soot particles emitted by human activity justifies the large number of studies on this topic. By the way, the characterization of urban aerosol has underlined the major contribution of these particles to global urban pollution. However, the commercially available devices are not always well suited for the study of soot particles, especially when mass information is needed. The present study deals with the possibility to establish, from a number size distribution of soot particles, a mass size distribution. For this purpose, the knowledge of mass evolution versus diameter for soot aggregates is primordial. In this work, we have determined experimentally the relationship between soot effective density and aerodynamic/mobility diameters. In parallel to this study, a determination of bulk density of soot particles has been made, and comparison between this bulk density and the effective density of primary particles has underlined the reliability of our method. The results presented here deal with combustion aerosol emitted by three different fuels: acetylene, toluene and PMMA, and show promising results.
