악취배출시설별 공기희석관능법의 희석배수와 악취센서 측정치의 상관성 분석

The correlation analysis between odor sensor and air dilution olfactometry method with odor emission facilitieswas performed for the real-time evaluation of odor emitted from the 13 facilities. The total correlation was lesssignificant for all facilities due to various emission characteristics of odor. The correlation for the individual facility,however, showed a higher correlation coefficient (R=0.7371~0.9897). Especially, the strong correlation (above 0.9)was observed for the industry type with the odor characteristics like tobacco, styrofoam, acetic acid, and burningsmell. The repeated odor measurements using the odor sensor showed good reproducibility with the mean relativestandard deviation of 5.06%. The odor sensor could be useful tools for identifying and evaluating odor with anolfactometry in field, if the use and proofreading of the odor sensor are improved by a standardized method.
