Objectives: This study was carried out to investigate the characteristics of odors emitted from sewage in asanitary sewer and its outlets. Methods: The concentration of mal-odorous sulfur was analyzed by gas chromatograph, and odor intensity wasestimated by an on-site sensory test. Odor intensity calculated from instrumental analysis results was comparedwith odor intensity observed at field. Results: As a results, the concentration of H2S ranged from 2.4 ppb to 5,889 ppb (average 703 ppb), whileCH3SH, (CH3)2S, and (CH3)2S2 showed from 10 ppb to 554 ppb (average 119 ppb) and from 20 ppb to 332 ppb(average 70 ppb) and from 2.7 ppb to 8.1 ppb (average 5 ppb) individually. Average odor intensity observed inthe field was degree three. Odor intensity calculated from sulfur compound concentration was confirmed assimilar to the observed odor intensity because the coefficient of variance between the observed and the calculatedintensities was less than one. Conclusion: It was expected that the results of this study will be helpful to design a deodorizing device to reduceodor emissions from sewerage facilities in the future.
