This study analyzed the odor contribution rate using AERMOD at odor emission facilities in an urban industrial area (North-Daejeon, Korea) where residential facilities, industrial complexes, and public environmental facilities are mixed. When comparing the average odor emission concentration by prevention facility, the multistage treatment method including oxidation and combustion was about three times more effective in reducing the concentration than the commonly used biofilter and scrubber. These results suggest the importance of management aspects of prevention facilities such as biofilters and cleaning towers to improve treatment efficiency. Currently, management of odor emission facilities is being conducted in terms of instantaneous odor concentration management. Due to the limitations of this management method, research results show that some workplaces ranked 7th in terms of momentary odor concentration level, but in terms of emissions, they soared to 2nd place, indicating that management from the perspective of emissions as well as concentration is necessary for odor management. The odor impact in the study area varies by season, but public environmental facilities have an impact of 62~76% in spring, summer, and winter, and odor emission facilities in industrial complexes have an impact of 66% in autumn. It can be inferred from these results that the odor impact of public environmental facilities would be low because they are located away from residential areas, but the results confirmed through this study showed that the concentration and emission levels of prevention facilities operated in public environmental facilities were relatively higher than those of odor-emitting facilities in industrial complexes.
