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

The odor quotient and the odor contribution was calculated.Results: Ammonia, hydrogen sulfide, acetaldehyde, and toluene were detected in all samples for monitoring specified odor compounds. The result of contribution analysis is that hydrogen sulfide had the highest contribution in all processes, followed by acetaldehyde.
Conclusion:The major components of odor can be determined by evaluating the degree of contribution to the odor intensity and the concentration of the individual odor component. To increase the effectiveness of odor reduction, rather than addressing high-concentration odor compounds, policies focused on materials with a high odor contribution are necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
