The study of aerosol particle sources is essential to improve air quality, thus reducing their health impacts (Kelly et Fussell 2015). In Europe, more than 400 000 premature deaths have been attributed to fine particle exposure (EEA 2020). France, for instance, is still affected by relatively high particle matter (PM) concentrations and, with several exceedances the daily PM2.5 concentration of 25 μg m-3 recommended by WHO (EEA 2020). More specifically, the north of France is considered a pollution hotspot, affected by heavy traffic, high urban density, significant agricultural activities overlapped with transnational pollution transport (UK, Benelux, Germany, etc.).
