This study investigated the characteristics of odor emissions from Public Environmental Facilities in Gwangju by analyzing both complex odors and designated odorous substances. The measured data were further examined using statistical analysis to identify the relationships between complex odors and designated odorous substances. Dilution factor of complex odor at facility boundary areas ranged from 3 to 10. Three were large variations in sewage treatment facilities, particularly at outlets for sedimentation basins and sludge-thickening tanks. Among the 22 designated odorous substances analyzed at the boundary area, eight substances exceeded their threshold concentrations. The most frequently detected substances were hydrogen sulfide, methyl mercaptan, and various aldehydes. At the emission outlets, odor profiles varied by facility type: sulfur compounds dominated at sewage treatment plants, whereas ammonia and aldehydes were prominent at food waste treatment facilities. Contribution analysis showed that sulfur compounds were the primary odor sources at sewage and sanitation facilities, whereas aldehydes were the main contributiors at food waste treatment facilities. Correlation analysis revealed strong associations between complex odors and hydrogen sulfide, methyl mercaptan and dimethyl sulfide. Multiple regression analysis showed that five key odorous substances explained 78.6% of the variation in dilution factor of complex odor, emphasizing the need for targeted odor control strategies.
