Sažetak
Properties, (trans)formation, and removal of organic particles remain the least understood aspects of atmospheric chemistry despite the importance of organic aerosol (OA) for both human health and climate change. Organosulfur compounds (OS) have come into the focus of atmospheric research as significant reservoirs of S in the atmosphere, being important components of formation of secondary organic aerosol (SOA), especially in the oceanic region. A range of global exchange processes between the sea and atmosphere is hindered by the sea surface microlayer (SML), serving both as a sink and source of marine organic aerosols. A progressive approach to understanding the SML chemical composition and, hence, its role in global biogeochemistry can only be achieved by considering all the key components of this complex environment as an integrated whole. We will present our study on the linkage of the ocean and the atmosphere through detail chemical characterization of organic matter with the emphasis on OS, of both the SML as well as of marine aerosols collected at Middle Adriatic area during the spring and summer period. For that purpose a complex methodological approach was applied including high-performance liquid chromatography coupled with tandem mass spectrometry, ion chromatography, inductively coupled plasma optical emission spectrometry and electrochemistry.
