Abstract

To better understand the wet scavenging processes of organic aerosols from the atmosphere, aerosol and rain samples were simultaneously collected in suburban Tokyo and analyzed for neutral lipid components using a capillary gas chromatography (GC) and GC/mass spectrometry. n-Alkanes, unresolved complex mixture of hydrocarbons (UCM), polycyclic aromatic hydrocarbons (PAHs), n-alcohols and sterols were determined in both aerosol and rainwater samples. Concentrations of n-alkanes, UCM and PAHs that originate from terrestrial higher plants or anthropogenic sources, were found to decrease with time during precipitation in both rain and aerosols. In contrast, concentrations of n-alcohols (<C<sub>20</sub>) and cholesterol that are characteristic to marine organisms generally increased during precipitation events. This study demonstrates that composition and concentrations of organic compounds in rain and aerosol samples during wet precipitation can be controlled not only by the scavenging process but also by a likely inflow of air mass of marine origin.
