Korea is a country where the population is concentrated in metropolitan areas that have undergone rapid industrial development. As of 2020, more than 43% of the total population lives in large cities, and about 18.5% of the total population lives in Seoul. A basic human need living in such a metropolis is a pleasant environment. In this study, complex odors and designated odors were evaluated at the boundary areas and at the outlets for 15 public environmental facilities selected from among odor sources in Seoul. As a result of measuring the complex odor intensity was 3 ~ 6 times at the boundary areas and 100 ~ 4,481 times at the outlets. In food waste treatment facilities, incineration facilities, and waste transfer station facilities, the compound making the largest contribution to odor is acetaldehyde, which was recorded at 46%, 25%, and 32% respectively. At a sewage treatment facility and agro-fisheries wholesale market, hydrogen sulfide was the largest contributing compound at 71% and 29% respectively.
