Emissions of air pollutants and greenhouse gases (GHGs) from aircraft activities at 11 small-scale airports were investigated using the emissions and dispersion modeling system (EDMS) version 5.1.3 during the two year period of 2009~2010. The number of landing and take-off (LTO) at these airports was dominant for the aircraft type B737, accounting for more than 60% of the total LTOs. Out of the 11 small-scale airports, Gwangju (GJ. RKJJ) airport was the larest emitter of air pollutants and GHGs, whereas Yangyang (YY.RKNY) airport was the smallest emitter. The emissions of Nox and VOCs in 2010 at the 11 airports ranged from 1.9 to 83 ton/y and 0.1 to 17 ton/y, respectively. In 2010, the emissions of CO2 ranged from 394 to 21,217 ton/y. The emissions of most air pollutants (except for NOx and PM10) and GHGs were estimated to be the highest in taxi-out mode. The highest emissions of NOx and PM10 were emitted from climb-out and approach modes, respectively. In addition, the total LTOs at the 11 small-scale airports accounted for the range of 9.3~9.9% of those at four major international airports in Korea. The total emissions of air pollutants and GHGs at the 11 airports ranged from 4.8 to 12% of those at the four major airports.
2015~2016년 경남지역의 PM<sub>2.5</sub>의 시·공간적 특성

Characterization of spatio-temporal variations in PM<sub>2.5</sub> in Gyeongnam (GN) province during 2015-2016 was investigated to assess the air quality in this area in terms of fine particles. Yearly mean concentrations of PM<sub>2.5</sub> ranged from 19.1 to 29.5 μgm<sup>-3</sup>. High concentrations of PM<sub>2.5</sub> were observed in spring (21.2-30.3 μgm<sup>-3</sup>) and winter (20.2-30.3 μgm<sup>-3</sup>). Low concentrations of PM<sub>2.5</sub> were generally observed in fall (16.2-23.2 μgm<sup>-3</sup>). PM<sub>2.5</sub> concentration was highest in the morning (10 AM). The fractions of PM<sub>2.5</sub> in PM<sub>10</sub> were 0.51-0.62 and two were significantly correlated (r=0.779-0.830), suggesting common sources (fossil fuel combustion, mobile sources, etc). CO was significantly correlated with PM<sub>2.5</sub> in highly urbanized areas such as the city of Changwon (CW, r=0.711), compared to other air pollutants (SO<sub>2</sub>, NO<sub>2</sub>, and O<sub>3</sub>), suggesting dominance of industrial combustion sources.
