In this study, leachate treatment facility (outlet, facility inside) and landfill sections (vent systems, landfill surface) of nine landfills is being buried in korea were studied emission characteristics of odor compounds. Air dilution value in ventpipes of landfill section was generally highest and was more 3 times higher than emission standard (air dilution value of facilities outlet : 500) in Daejeon, Tongyeong, and Busan landfill. Outlet of leachate treatment facilities in Tongyeong and Daegu landfill, in case, was higher respectively 20 times, 6 times than other landfills, commonly show that a large contribution to the odor of hydrogen sulfide. In case of ordor emission rate, ammonia and hydrogen sulfide were surveyed to comprise a high rate for odor emission rate. Odor emissions based on landfill scale, large landfill (Sudokwon) and small landfills (Yeosu, Chuncheon, Chungju) is low in odor emissions per unit area, whereas medium landfill (Busan, Daejeon, Daegu) was estimated to be high odor emissions. In case of large landfill, leachate treatment facilities is management in good condition and discharged odor emission of landfill sections was low into ambient air. In case of small landfill, decay gases and leachate is few. Therefore odor emissions is fewer than estimated medium landfill. In case of medium landfill, management condition of leachate treatment facility was in poor and landfill sections was under not stabilization stage. Thus, medium landfills was identified that needs to be intensive care. Keywords : Landfill, Leachate treatment facility, Air dilution value, Emission rate, Dynamic flux chamber
