Abstract
In this study, we focused on typically problematic sulfide compounds Gas samples were captured at Unjung-ding landfill site in Metropolitan Kwangju with flux chamber and floating chamber, and analyzed for the amount of hydrogen sulfide($H_2S$), dimethyl sulfide $((CH_3)_2S)$ and dimethyl disulfide$((CH_3)_2S_2)$. From the gas pipe, landfill surface and leachate treatment plant, estimated total amount of $H_2S$ emission are 12.6ton/yr, 0.01ton/yr and 1.04ton/yr; estimated total amount of $((CH_3)_2S)$ 30.7ton/yr, 0.08ton/yr and 1.72ton/yr; and estimated total amount of ($((CH_3)_2S_2)$ 2.2tom/yr, 0.02ton/yr and 1.03ton/yr, respectively. Further in-depth study on co-relation between age, packing characteristics, temperature and humidity of landfill site and gas emission characteristics is needed.
