우리나라의 악취배출 허용기준에는 직접관능법, 공기희석관능법 및 기기분석법에 의한 측정과 규제 기준을 제시하고 있다. 직접관능법의 경우 신속하고 간편하여 현장에서 바로 판정을 내릴 수 있다는 점에서 부지경계선상에서의 악취의 평가수단으로 이용되어 현재까지 많은 평가서에 측정결과를 제시하고 있다. 그러나 직접관능법에 의한 평가결과가 규제치를 넘어 법적 조치가 이루어진 사업장은 거의 없는 듯하다. (중략)

산업이 발달하고 경제가 성장될수록 환경을 오염시키는 신종 오염물질은 계속 증가하는 반면 인간의 삶의 질 향상으로 대기질 개선에 대한 욕구는 과거에 비하여 훨씬 더 높아지고 있다. 산업화이전 악취에 대한 오염문제는 다른 환경 오염에 비하여 아주 작은 위치를 차지하였지만 현대에 와서는 대기오염문제에서 빼놓을 수 없는 사회문제로 대두되고 있다. 악취 원인물질을 정확하게 분석하는 것은 매우 어렵다. 악취에 관한 국내의 측정방법은 대기오염공정시험법에서 직접관능법과 공기희석관능법, 그리고 일부항목에 대한 기기분석법이 제시되고 있다.

This study is to develop the production method of stepwise dilution gas for the evaluation of complex odor concentration by orifice tube. The basic orifice tube for 10 and 30 times of dilution sample was made at first, and with the combination of the basic orifice tubes we can continuously manufacture the stepwise dilution sample gas for air dilution sensory test ; 10, 30, 100, 300, 1,000, 3,000 times etc. The hole size of orifice tube was 0.84 mm for 10 times of dilution sample, and was 0.34 mm for 30 times. Dilution sample gas made with the basic orifice tube have an excellent reproducibility, 2%RSD. In addition, over 90% of correlation was shown between the sample made by the orifice tube and the sample by the syringe dilution method. Because there was no concentration drift of dilution gas with changes of connected pump flow, the basic orifice tube could be mounted directly with a vacuum suction box, and could be used simply as a tool for the evaluation of odor, especially on site.

악취현상은 더 이상 대기오염물질에 한 형태가 아니며 또다른 하나의 감각공해라는 개념이 점차 확산되면서 악취에 대한 관심이 점차 고조되고 있다. 그러나 악취현상의 규명이 국내는 물론 국외에서도 충분한 근거를 제공받지 못하는 데에는 첫째, 대기환경 중에 악취물질은 약 40만종 이상이며, 각 물질의 최소감지 농도(threshold:역치) 값 자체가 수ppm∼수ppb 이하 수준이므로 물질농도를 정확히 규명하는 데에는 물질 고유의 특성과 더불어 상당한 수준의 기술과 장비가 요구된다. (중략)

This study aimed to provide the basic data to establish measures for the management of the public toilets and reduction of the offensive odor through the air dilution olfactory method and instrumental analysis about offensive odor dilution rate of public toilets, focusing on the Dong-gu, Daejeon Metropolitan City, Korea. The offensive odor intensities ranged from 10 degree to 669 degrees in the urinal toilets and from 31 to 464 in closet bowl toilets. Meanwhile, toilets that had offensive odor of more than 2.5, of which a civil complaint can be filed, were researched 6 (33%). Offensive odor intensities were different according to the closet bowl toilets of the flush, fermented and conventional methods and the year of their installation, but not according to the area of the toilets. As a result of the instrumental analysis targeting 6 public toilets to identify the offensive odor substance, the maximal concentration of $NH_3$ was 2.04 ppm and the average concentration was 0.67 ppm, but $H_2S$, $CH_3SH$ and $(CH_3)_3N$ were not detected. In the fermented and conventional public toilets were not soaps, air fresheners and wastebaskets. Just 50% of the flush toilets had toilet tissue.

In this study, we attempted to evaluate the relationship between air dilution sensory test and instrumental detection method for individual odorous compound. For the purpose of our comparative study, we conducted the analysis of malodor on total of 46 samples collected from both industrial and food waste sectors using the two independent approaches. The results of instrumental analyses were explained after modification to several parameters such as: the sum of odor concentration (SOC), sum of odor quotient (SOQ) and sum of odor intensity (SOI). When we compared dilution ratio values (DRV) of threshold limit (TL) with the modified instrumental data sets, pearson coefficient of SOC, SOQ, and SOI were 0.556 (p=5.83E-05), 0.911 (p=9.64E-19) and 0.847 (p=8.93E-14), respectively. The results of this study thus suggest that the DRV of TL sensitively reflects odor strength measured intuitive.
