The observed fluorescence was assigned to particles bearing polycyclic aromatic hydrocarbons (PAH). This assignment was supported by an intercomparison with classical speciation on filters followed by gas chromatography-mass spectrometry (GC-MS) analysis. As compared with daily-averaged data, our time resolved approach provided information about the physicochemical dynamics of the particles. In particular, distinctions were made between background emissions related to heating, and traffic peaks during rush hours. Also, the evolution of the peak fluorescence wavelength provided an indication of the aging of the particles during the day. arXiv: 1707.05177 - http://arxiv.org/abs/1707.05177 Aerosols Monitoring Fluorescence Polycyclic aromatic hydrocarbons Identification Pollution Real time Dewey 333.7-333.9 Dewey 500.2 Swiss National Science Foundation NCCR MUST CH European Commission Laser Identification of Pollen and Bacteria in Air 632156 LIPBA EU FP7 18 Institut des sciences de l'environnement 0DB 35 Groupe de physique appliquée 135 false 943 ISE Climat 938 ISE Pôle Sciences Environmental science and pollution research international 24 24 eebe1c8a-c79f-4b5d-907c-40205b3e3204 Article (Accepted version) Public Biobox_HAP_Geneve_arXiv.pdf 474141 application/pdf a9ee556c-3cd5-4f17-8c97-cfa42f6ec4e8 Article (Published version) Restricted 2017_Souza_time_resolved.pdf 1206568 application/pdf openAccess Centres et instituts / Institut des sciences de l'environnement Faculté des sciences / Section de physique / Groupe de physique appliquée
