Investigation of the odor source is necessary to establish of the effective counter plan for reducing the odor emitted from the industrial complexes. This study was carried out to investigate the characteristics of the odor emitted from leather manufacturing plants, using three methods which are a direct sensory technique, an air dilution sensory test and a instrumental analysis. Total 7 samples were sampled at 3 points of three factories in this study. As a results of this study, while odor intensity of 7 samples ranges from 2 degree to 4 degree, dilution ration of olfactory test shows the range from 300 to 600. It was estimated that main malodorous compounds ordered hydrogen sulfide, methyl mercaptan, i-valeraldehyde.
