The objective method, combined sensory and instrumental analysis, was desired to evaluation of intensity as well as odor active compounds because malodor is sensory pollution. This work was carried out to investigate emission characteristics of odor materials from muncipal waste landfill at Yeosu city. Target compounds were odor materials such as sulfur compounds, aromatic compounds, ammonia, carbonyl compounds and ketone, fatty acid and amine. The odor intensity and the ammonia concentration at landfill site in Yeosu city was in the orders : R-1 < M-4 < M-1 < M-5 < M-3 < M-2 and R-1 < M-4 < M-5 < M-1 < M-3 < M-2, respectively. Ammonia concentration identified at M-2 and M-3 site was exceeded the Korean odor regulations. The sulfur compounds concentration at landfill site was in the order : (CH3)2S < CH3SH < (CH3)2S2 < H2S. The emission of aromatic compounds were consistently observed at tota1 landfill site. Toluene appeared to be the most abundant one among aromatic compounds. The carbonyl compounds concentration at landfill site was in the order : n-Valeraldehyde < iso-Valeraldehyde < Butyraldehyde < Propionaldehyde < Acetaldehyde. Major odor compounds related at landfill site were found to be sulfur compounds(H2S), aromatic compounds(Toluene) and carbonyl compounds (Acetaldehyde).
