| Abstract: | PM2.5 aerosol samples were collected at Gosan in Jeju Island during six intensive measurement periods between November 2001 and
August 2003. In order to investigate the chemical composition of fine particles, major ion components, trace elements, and
elemental and organic carbon were analyzed. Quite different seasonal characteristic in the chemical composition of fine particles
was observed. The concentration of most secondary aerosol components showed a summer minimum and a winter maximum with higher
correlation between them at Gosan. This fact clearly reveals the possibility of long-range transport of such pollutants in
winter. On the other hand, OC and EC had the highest concentration and good correlation with ion components, such as K+, Ca2+ in fall. It means that biomass burning could significantly influence the ambient fine carbonaceous particulate in fall, which
was primarily long-range transported. |
