새만금 간척지 지역 미세먼지 특성

The Jeonbuk region is an area with high concentration of particulate matter. Due to environmental changes in the Saemangeum reclaimed land with an area of 219 ㎢, it is necessary to evaluate the impact of the particulate matter in the Jeonbuk region. Particulate matter was measured from June in 2020, the Jangjado island the westernmost region, was set as the background concentration, and three measurement station were installed around the Saemangeum reclaimed land area. In addition, the concentration of particulate matter and air pollutants were measured by installing an intensive air quality measurement station in the Kehwa rice experiment station nearby Saemangeum reclaimed land. The concentrations of PM10 and PM2.5 were highest in the order of Gimje, Buan, Gunsan, and Jangjado(background concentration) area in June. However, it has changed seasonally. The total suspended particle(TSP) was high in Gimje and Buan, where compartment and leveling work are actively underway. The concentration of PM10, PM2.5, NO2, SO4, O3 were measured lower than that of the urban air quality monitoring station located in the nearby area. It was needed that longer-term air quality monitoring was necessary for accurate impact assessment.
