This study examines air pollutant emissions from agricultural activities in paddy fields and cropland areas in Buan and Gochang, South Korea. From June 2022 to May 2024, air quality monitoring stations collected data on particulate matter (PM-10, PM-2.5) and gaseous pollutants (NO2, SO2, O3). The findings indicate that particulate matter levels were notably higher in spring and fall, due to farming activities like herbicide application and crop harvesting. In contrast, gaseous pollutant levels remained within national air quality standards, although SO2 displayed unique seasonal patterns, particularly in the paddy field areas, where concentrations were higher in the mornings and afternoons. A comparison between urban and agricultural areas showed similar patterns for particulate matter, influenced by external factors like dust storms, but agricultural areas exhibited higher concentrations during farming seasons. The study emphasizes the importance of establishing dedicated air quality monitoring systems in agricultural regions, as the emission characteristics differ significantly from urban areas. Future research is needed to investigate the chemical composition of finding particulate matter in these regions to develop more effective pollution control strategies and improve overall air quality management in agricultural areas.
