Identification des sources et facteurs d'influence de la pollution aux particules ultrafines au niveau d'un site de fond parisien

Abstract : The French community involved in air quality monitoring early got interested in the measurement of submicronic particles. Since 2003 INERIS has carried out monitoring campaigns once or twice a year in an urban site located near Paris, enabling the constitution of a large hourly database. Besides air quality measurements, other variables have been introduced into the database: traffic and heating emissions provided by the local air quality monitoring agency (AIRPARIF) ; meteorological variables issued from monitoring or extracted from the meteorological MM5 model (height of the boundary layer). An exploratory study of the data collected from 2003 to 2007 has been performed. Two physically independent factors prove to play a significant role in the evolution of submicronic particle concentrations: emissions, especially traffic emissions, and atmospheric dispersion conditions.
