The objectives of this study were to analyze the characteristics of odor in the major facilities of a fishery industrial complex using the air dilution olfactory method and the instrumental analysis method. The results indicate that although the limit of dilution to threshold (D/T) ratio in the major facilities is not regulated by the Odor Emission Standard, the mean (D/T) ratio over than 3,000 which is higher than the limit in the outlet of industrial area 3 times was found at three sampling sites. In the case of the concentration of the malodorous compounds, ammonia concentration is higher than any other odor compounds. The methyl mercaptan, n-Butyric acid and hydrogen sulfide as the main pollutants are confirmed by the odor quotient (OQ). In our study, it is showed a moderately good correlation between the (D/T) ratio and the sum of OQ. By this result, we can estimate the odor characteristics and evaluate the potential impact of each odor compound. In addition, we consider that it will affect the people"s normal life and even cause for complaint around the boundary area by the diffusion of odor.
