  • The purpose of this study is to analyze the pattern distribution of the odorous compounds and air pollutants from the inventory sources in the Cheon-an second industrial complex. Twelve analysis including specified odor materials and air pollutants were concurrently measured during the month of August, 2005 to evalaute odor emission characterization in m3;or treatment facilities. Also, Concentration of air pollutants has been calculated by ISCST3 in ISC3 models. A Korean air diffusion modeling software, Air Master, was developed on a basis of diffusion theories adopted in U.S. EPA's ISC3 model to assess the air quality impact from the stacks. This investigation will be executed how large the complex pollutant sources such as industrial complex contribute to atmospheric environment and air quality of the surrounding the area as predicting by comparing and analyzing results of odorous compounds and air pollutants diffusion concentration model.

  • This research was conducted on characteristic of offensive odors in Shihwa industrial complex. Result of blocks distribution of TVOC indicates that mechanic block, site D, was the highest concentration (74 ppb). Chemistry block, site A, was the second highest concentration (50 ppb). Also, mixed blocks, metal blocks and park etc. were measured almost similar concentration about 30 ppb, but mixed block, site F, was the place where concentrations were the smallest. Average of TVOC was shown about 35 ppb concentration. Aldehydes including acetaldehyde, butyraldehyde and hydrogen sulfide concentrations were prevalent among offensive odors in Shihwa industrial complex. Comparing the offensive odor intensity mostly about acetaldehyde, butyraldehyde and hydrogen sulfide which contain high offensive odor intensity showed results that sites A, B (chemistry block) and site D, I (mechanic block) site H (metal block) have showed the intensity over 1. In the case of acetaldehyde, relatively the high odor intensities over '2' were able to obtain in many cases. The correlation coefficient (r) for hydrogen sulfide was 0.91, so that high positive correlation exists between offensive odor intensity and the hydrogen sulfide element. Butyraldehyde also showed high positive correlation coefficient, as 0.82. Correlation coefficient of acetaldehyde that had the highest value as offensive odor substance was 0.62, had somewhat correlation with offensive odor intensity.

  • 국가적으로 운영되는 국가산업단지는 악취를 포함한 유해 대기오염물질이 다량으로 배출되어 악취 피해의 민원이 증가하면서 이에 따른 악취 저감 대책 및 규제대책 마련에 관심도가 높아지고 있다. 특히 악취는 여러 가지 성분이 복합적으로 존재하고 후각에 의해 인지되기 때문에, 감각공해로서 후각의 개인적 차이와 기후와 지리적 여건에 따라 그 피해 정도가 달라지게 된다. 이러한 악취의 특성을 고려하면, 정량적으로 산출하기가 매우 까다롭고, 그에 따른 악취규제대책 마련도 매우 복잡할 수 있다. (중략)

  • It would be the most effective way to have government take care of social problems and hazardous material danger due to odor. It is also well known that odor acceptance and their willingness to pay for resolving the odor problem vary person by person. This is why public sector's intervention is required to get ride of any possibility of market failure resulted from negative external effect of human. This paper has tried to do empirical research based on survey of residents who are currently living in the area of Ochang industrial complex in North Chong-chung province. According to the empirical research results, first of all, it was proven residents' perception of legal regulation has a negative effect on odor acceptance. That is, the more residents are aware of law and regulation, the less they tend to accept odor. In addition, resident's perception on need to improve odor regulation has a positive impact on their odor acceptance. Finally, residents' satisfaction on the legal complaints to local government has an interaction effect to causative relationship between the perception of improving odor regulation and odor acceptance.

  • 차량의 증가와 각종 산업분야에서의 유기용제 사용에 따른 VOC 물질의 증가는 발암성과 관련된 환경보건 및 오존의 전구물질 등 기타 복잡한 대기화학과도 긴밀하게 연루되어 있다. 또한, VOC는 공단지역에서 지역주민에게 악취를 유발시키는 있어 악취와 건강보건에 있어서 집중적인 관리가 요구된다고 하겠다.(중략)

  • 산업화가 급속히 진행됨에 따라 삶의 질은 향상된 반면, 대기오염으로 인한 피해는 증가하고 있다. 대기 중 존재하는 휘발성 유기화합물 (VOCs)은 인체에 독성을 가지며 암을 유발하고, 오존의 전구물질(precursor), 광화학 스모그의 원인물질, 성층권의 오존층 파괴 및 지구온난화에도 영향을 미칠 뿐 아니라 (Derwent et al., 1996) 악취를 유발하기도 한다. 악취는 황화수소(hydrogen sulfide), 메르캅탄류(mercaptans), 아민류(amines) 등 기타 자극성 있는 기체상 물질이 사람의 후각을 자극하여 불쾌감과 혐오감을 주는 냄새로 정의되며, 주로 인체의 위해성보다는 정신적ㆍ심리적인 피해를 일으키는 감각공해라고 할 수 있다 (환경부, 2002).

  • In this study, the distribution patterns of major odorous compounds in ambient air were investigated in the areas surrounding the Ban-Wall industrial complex of Ansan, Korea (Aug. 2004 to Sep. 2005). The results indicated the environmental significance of several major odorous compounds which include carbonyl compounds, reduced sulfur compounds (RSC), and volatile organic compounds (VOC). When the results were compared on a diurnal basis, the afternoon time concentration of most odorous compounds were notably higher than their morning time counterparts. It also indicated that the odor concentrations differed greatly, in terms of spatial grouping scheme of data sets, such as between industrial area and non-industrial area. The comparison of spatial patterns indicated that the concentrations of most of the compounds at the industrial area were maintained at high concentration levels, compared to the surrounding areas. The overall results of this study thus suggest that the distribution of odorous compounds in a large industrial complex can exhibit a unique pattern of their own.

  • As a typical example of simultaneous analysis of the odorous compounds, the volatile organic compounds from inventory sources in Seongseo industrial area were concentrated and analyzed with thermal desorber/GC/MSD, and major malodorous compounds were estimated. Odor intensity and odor concentration was analyzed simultaneously During a period from November in 2002 to December in 2003, this study was conducted to evaluate malodor emission characterization in major treatment facilities. The major components were Dimethyl sulfide, Dimethyl disulfide, Methyl mercaptane, Ammonia, Benzene, Toluene, m,p-xylene, o-xylene, Styrene, 1,2,4­T.M.B and 1,3,5-T.M.B. Among the six major inventory sources, the odor unit concentration of Night-soil disposal facilities was the highest, $669\~2344\;ou/m^{3}.$
