08 - Application of Atomic Force Microscopy in Characterization of Marine Aerosols

Abstract

The current knowledge in aerosol science is still incapable to give a real and quantitative assessment of their actual impact on global climate and health. This problem arises from the fact that, until today, there is insufficient knowledge regarding aerosol sources, mechanisms of formation, aerosol properties and chemical composition. In this study, atomic force microscopy (AFM) was applied for characterization/imaging of water soluble fraction of marine aerosols. Obtained results were discussed in terms of water soluble organic matter results obtained by high temperature catalytic oxidation (HTCO) and electrochemistry. Each technique characterized different chemical components of marine aerosols and provided complementary information.
