This study analyzed emission inventories and air quality monitoring data for the Gwangyang Bay Area, including Gwangyang-si, Yeosu-si, Hadong-gun, and Namhae-gun, using the Clean Air Policy Support System (CAPSS). Annual trends and correlations were examined over the period 2011-2021. 1) The annual average increase rate of change in total emissions (2011-2021) showed a decrease -8 to -9% for PM10, PM2.5, and SOx and -2% for NOx, but an increase +3% for VOCs and CO. The contribution rates of Yeosu and Gwangyang were very high, at 78-96%. 2) The concentrations of SO2,
NO2, CO, PM10, and PM2.5 showed a decreasing trend. In Gwangyang and Yeosu, SO2 and NO2 concentrations began to decrease gradually from 2000 onward. O3 concentrations showed an increasing trend, and as of 2023, were highest in the following order: NH and GS sites (36 ppb) > HD site (35 ppb) > WN site (32 ppb) > TI site (27 ppb). 3) Very high correlations were found between SOx and NOx emissions, and SO2 and NO2 concentrations. O3 concentrations were found to be highly correlated with increasing VOCs emissions and decreasing NOx emissions. The influence of overseas inflow may have contributed more to the decrease in PM10 and PM2.5 concentration than the reduction in emissions alone.
