French Network on Ultrafine Particles Monitoring: first results
Abstract
Since 2012, various projects have been dedicated to airborne ultrafine particles by French regional air quality monitoring networks (in Rhône-Alpes, Aquitaine, and Provence-Alpes-Côte d’Azur), constituting the first French UFP monitoring “observatory”. These projects were carried out in close collaboration between each network and with the French reference laboratory for air quality monitoring (LCSQA), leading to the building up of a national Working Group on UFP. Several questions are addressed, including the identification and quantification of local industrial sources, the assessment of the impact of industrial, traffic and residential heating emissions on total particle number, as well as the investigation of phenomena’s (meteorology, photochemistry, etc...) influencing urban background concentrations...
