In this study, the grid field olfactory odor method was supplemented to the domestic situation in the surrounding areas of a domestic science industrial complex. The actual condition of the occurrence of odor frequency in the field was then investigated over the first period of late spring to summer and the second period of autumn in 2017. The frequency of odor occurrence in the area around the science industrial complex was increased as odor discharge facilities in the nearby area were concentrated. The odor occurrence frequency of the total period was 0.09~0.28, that of the first period was 0.08~0.32, and that of the second period was 0.05~0.25. The odor occurrence frequency in summer was higher than in autumn. The frequency by which the measurement of odor occurrence by smell type was most dominant was mainly smell of chemicals, plastics, and livestock houses during the first period, and the smell of chemicals, burning gases, and plastics during the second period. And the frequency of each smell type was judged to be different according to season. The odor occurrence frequency was measured as higher than 0.15, which is the standard of Germany's odor frequency in an industrial area, and it was judged that measures for odor management in the region were necessary. Since most of the odor discharge facilities are non-continuous systems and the odor generation frequency is more important than the concentration of the minimum detection concentration, it was judged that the German grid method can reflect the odor occurrence characteristics of the odor complaints or receptors for a certain period of time compared to the domestic measurement method. In the future, it was judged that the field olfactory odor method would be able to replace the evaluation method of odor assessment in Korea with the survey method of odor assessment under actual conditions in areas where it is difficult to access the odor discharge source or the receptor where odor complaints occur.

The purpose of this study was to investigate the current status of odor and to examine the application method of the odor emission standard in a restaurant environment. The complex odor dilution concentrations (“times”) and odor compounds were measured in 8 restaurants. The highest complex odor dilution times were 966 in outlets and 97 in site boundaries of C restaurants. The average complex odor dilution times were 632 in outlets and 29 in site boundaries, which exceeded the allowable odor discharge standard of residential areas. Eighteen of the 22 specified offensive odor substances were detected. Aldehyde-type substances showed high concentrations, and the highest concentration of ethanol was detected in addition to the designated odorous substances. Dichloromethane, benzene, and phenol, which are harmful air pollutants, were also detected. The odorant concentrations of restaurants were found to exceed the odor standard threshold in A, B, and F restaurants. Upon review of the Japanese-style odor index respective to restaurant odor, it is difficult to apply an equivalent emission allowance standard as the permissible emission standard of the workplace. It is necessary to regulate emission standards by different emission standards. In the future, it will be necessary to determine how to measure the odor index and how to apply the odor emission standard to everyday facilities, such as restaurants, grocery stores, etc.

In this study, a correlation analysis of odor was performed in order to assess the reliability and the field applicabilityof the Odorous gas sensor for continuous real-time monitoring. Hydrogen sulfide was found to have a correlationof 41.5~65.8%, and Ammonia is was found to have very low correlation in less than 200 ppb concentration. Reactivity evaluation result, hydrogen sulfide is the reactivity was higher than the low concentration condition of100 ppb or less indicated by 31.3~36.4% in the 100 ppb or more high density condition based on the referencedensity value. For ammonia was very low reactivity in the low-concentration conditions below 200 ppb. TVOCand composite odor assessment did not occur Reactivity no reference concentration value, the specific comparisonbetween both sensors showed a similar trend. In the same Odorous gas sensor accuracy between the result,40.3~130.6% hydrogen sulfide, ammonia, 69.1~104.9%, TVOCs is 24.7~98.6%, exhibited human odor intensityfrom 5.5~33.2%.
