Emissions of Air Pollutants and Greenhouse Gases from Aircraft Activities at the Gimhae International Airport

Emissions of air pollutants and greenhouse gases (GHGs) by aircraft at the Gimhae International Airport (GIA) were investigated using the Emissions and Dispersion Modeling System (EDMS) version 5.1.3. The number of Landing and Take-Off (LTO) at the GIA for aircraft B737 was dominant, accounting for more than 60% of the total LTOs. For air pollutant emissions, CO was the most dominant pollutant by aircraft, followed by NOx, VOCs, SOx, etc. The emissions of CO, NOx, and VOCs in 2009 (and 2010) at the GIA were 974 (968), 447 (433), 118 (122) ton/yr, respectively. The emissions of GHGs such as CO2, CH4, and N2O in 2009 (and 2010) were 110,795 (111,114), -0.157 (-0.151), and 1,989 (1,998) ton/yr, respectively. The negative number in CH4 emission represents the consumption of atmospheric CH4 in the engine. In addition, the emissions of most air pollutants (except for PM10) and GHGs were estimated to be high in Taxi-Out and Climb-Out modes.
