Abstract
- In this study, the impact of long-range transport, one of the factors contributing to the presence of PM<subscript>2.5</subscript>, was examined, and an analysis of marker compounds associated with its long-range transport was conducted. Aerosol optical depth, wind field, CO/CO<subscript>2</subscript> back-trajectory analysis, and satellite observation results were performed to determine PM<subscript>2.5</subscript>, volatile organic compound (VOC), CO, CO<subscript>2</subscript>, SO<subscript>2</subscript>, O<subscript>3</subscript>, NO, NO<subscript>2</subscript>, and NH<subscript>3</subscript> levels at an orchard located in Jeollabuk-do, Republic of Korea. The characteristic of long-range transport at the observation area was evaluated during the research period. The concentrations for long-range transport based on concentration changes in gaseous materials and composition changes in PM<subscript>2.5</subscript> were analyzed. A back-trajectory analysis for the ratio of CO to CO<subscript>2</subscript> with satellite observation results was used to identify long-range transport. Furthermore, the proportionality between the ratio of 1,2-dichloroethane to naphthalene in VOCs and the quantity of precursor compounds linked to long-range transport were observed.
