Aérosol submicronique en site urbain de fond : cas de la station de Genneviliers, hiver 2003

Abstract : This paper presents the preliminary results of a winter 2003 5 weeks field campaign which has been carried out at the urban background station of Gennevilliers Paris area. In order to characterise the exposure to submicrometer particles, a Differential Mobility Analyser has been employed in the 10 to 500 nm range. The statutory air survey parameters, and meteorological parameters have been also considered. The hourly 10 nm - 500 nm number concentration ranged from 1.500 to 83.500 p.cm-3 . The median value is 13.000 p.cm-3 . The ultrafine particles (< 100 nm) are the dominant mode. The lowest correlation coefficient (0.46) concerns the ultrafine mode and PM 10. It suggests a certain independence of these two parameters. The linkage is better between the 100-500 nm range and PM 2.5.
