Aerosols are important constituents of the atmosphere and secondary organic aerosols (SOA) represent a main fraction of the organic aerosols in the total budget. This thesis mainly reports the investigation of three aspects of the growth and aging of SOA: the photosensitized SOA growth ; the mechanistic investigation of SOA aging and of the photochemistry of photosensitizers ; the analysis of the chemical composition of aged SOA. The photosensitized growth and aging processes of SOA were investigated using an aerosol flow tube coupled with various aerosol and gas sensing instruments. For further analysis of the aerosol composition and a better understanding of the formation and growth of SOA in these experiments the aerosols produced in the...
