Objectives: This study evaluated the odor emission characteristics from fundamental environmental facilitiesat an industrial complex area in Daegu City. Methods: The odor samples were collected from May 2015 to January 2016 and were analyzed for specifiedoffensive odor substances. The odor quotient and the odor contribution was calculated. Results: Ammonia was detected in all samples monitoring specified odor compounds, followed by hydrogensulfide and acetaldehyde. According to contribution analysis, hydrogen sulfide shows the highest contribution inall facilities. At wastewater treatment plants A and B and sewage treatment plant F, it was followed byacetaldehyde. At wastewater treatment plant C, it was followed by imethyl sulfide. Conclusion: The major component of odor can be determined by evaluating the degree of contribution to theodor intensity rather than the concentration of the individual odor components. To increase the effectiveness ofodor reduction, policies focused on materials with a high odor contribution are needed rather than focusing onhigh-concentration odor compounds.
