This study aims to evaluate the relationship with the concentration and odor intensity using the odor sensory method for aromatic hydrocarbon, ketone and ester compounds. For the measurement, 18 panelists were selected by several criteria through a panel test. Panelists chosen for their closely similar sensitivities provide more reproducible values. The estimation showed that the correlation of the concentration with odor intensity for the 5 compounds including of the aromatic hydrocarbon, keton and ester compounds can be reasonably expressed by the equation I = A·log C + B (I :Odor Intensity, C : material concentration, A : material constant, B : constant). The result of this study is suggested to be used as a base data for research on measures to improve the regulation standards for complex odor concentration on site boundary in operation, as well as a correlation between the concentration and odor intensity for the designated foul odor substances, and their characteristics.

본 연구에서는 악취방지법에서 배출허용기준으로 설정하고 있는 지정악취물질중 m-자일렌과 톨루엔, 케톤류, 뷰틸아세테이트, 총 5개의종에 대하여 각 개별 물질농도와 악취강도와의 관계를 살펴보고자 하였다. 지정악취물질농도와 악취강도의 상관관계는 I = A·log C + B (A :물질상수, B :상수) 에 의해 적합하게 표현되었으며, 각 물질의 물질상수값을 제시하였다. 관계식의 물질상수(A)는 m-자일렌 1.6226, 메틸에틸케톤 1.5729, 톨루엔 1.4269, 메틸아이소뷰틸케톤 1.4254,뷰틸아세테이트 1.3706으로 나타났다. 악취강도 1도의 변화를 유발하기 위해서는 m-자이렌 4.13배, 메틸에틸케톤 4.32배,톨루엔 5.02배, 메틸아이소뷰틸케톤 5.03배, 뷰틸아세테이트 5.37배의 물질농도 변화가 필요한 것으로 나타났다.
