Odor management area was introduced by Odor prevention laws in 2004. Odor is generated a lot of sources. It is generated from various process as well as stack outlet. So it is hard to control odor. The ministry of environment develops the system to control odor. Nineteen areas were selected as Odor management area. Odor management area should be conducted for periodical research on the actual condition. Odor is normally measured by Odor analysis method. However, there are some difficulties to conduct by Odor management area because of measurement frequency, limitation of areas and high cost. Therefore we need to figure out how to reinforce this performance in Odor management area. So we have checked possibility of monitoring system with realtime odor monitoring, electron sensor, mobile communication and odor modeling system. The Odor monitoring system is consist of realtime monitoring system and electron sensor system. The Odor monitoring system could be checked for odor concentration and source of odor by accessing internet and mobile communication. 악취관리지역은 2004년 악취방지법이 제정되면서 악취관리지역의 개념이 도입 되었다. 악취의 발생원이 다양하고 배출구이외의 다양한 공정에서 발생하는 배출원의 관리 방법으로 해결이 어려워 지역전체의 관리차원으로 계획을 세우고 효율적 관리가 되도록 하였다. 악취관리지역으로 지정된 지역은 악취실태조사를 주기적으로 수행하여야 하며 현재 19개 지역이 지정되어 있다. 악취를 측정하는 방법은 악취공정시험방법에 의하여 측정을 수행하도록 되어 있으나, 악취의 측정빈도, 공간적 제한성, 고비용의 측정비용 등으로 악취관리지역에서의 실태조사는 좀더 보완이 필요한 때이다. 이에, 현장연속측정시스템, 취기를 측정하는 전자센서, 이동통신, 악취모델링 기법을 도입한 감시시스템의 구축방안과 이에 대한 가능성과 활용방안에 대하여 검토 하였다. 악취감시시스템은 현장연속측정시스템과 전자센서로 구성하며 인터넷과 이동통신방법으로 연결되어 악취농도 예측, 배출원 규명 등의 목적에 적용 가능성이 있는 것으로 보인다.

Incheon is an area where complaints about odors occur frequently and there are many sources of odor emission. In this study, we used a real-time monitoring device to measure the odorous concentration near the areas where there are complaints about odors. The measurements were carried out for the three areas (G, C, S) that are located around emissions sources. G is situated in an industrial complex that has a reputation for being one of the most foul smelling regions of Incheon. A petroleum refining plant and storage facility are located around C. S is a residential area nearby an industrial site. The concentration of major designated odor substances in the G and S areas satisfied the site boundary emission standards. With regard to the characteristics of odor substances by region, although the C area region had the highest odor intensity among the three regions due to the odor intensity near the oil storage facility areas G and S were similar in terms of odor intensity. In the region of the G area, the odor intensity was slightly higher at the northern side of the industrial complex. In terms of the odor intensity of the designated odor substances, trimethyl amine was the strongest, followed by hydrogen sulfide. The real time monitoring system was necessary to analyze the changing trends of odor substances and for the determination of major odor sources. This study was conducted to identify the material causes of odors in areas of Incheon where there are frequent complaints about major odors. .

박소영,Gökçe Nur Ayaz,김희원,윤형기,권태홍,김성균 한국환경보건학회 2024 한국환경보건학회지 Vol.50 No.2

Background: In this study, we investigate the rapid increase in environmental odors and notable rise in civil complaints near Dorim Stream in the Gwanak-gu area of Seoul. Objectives: This study aims to identify the causal compounds responsible for environmental odors in the Dorim Stream and investigate the structural characteristics of the stream that inf luence odor generation. Methods: The research methodology involved setting up 41 sampling points, selecting panels for direct sensory evaluation to assess odor intensity, measuring dissolved oxygen and hydrogen sulfide concentrations, and using all-in-one low-temperature desorption gas chromatography (ATD-GC) and thermal desorption- gas chromatography-mass spectrometry (TD-GC/MS) analysis to identify odor-causing compounds. Results: The evaluation of Dorim Stream revealed that in areas with complete meandering, there were lower dissolved oxygen levels (4.5±2.67 mg/L) and higher odor intensity (4.0±0.92), while in partially meandering sections, higher dissolved oxygen levels (7.8±1.15 mg/L) and lower odor intensity (2.8±1.06) were observed. Hydrogen sulfide levels measured with sensors increased with higher temperatures, especially in the afternoon hours (12:00~14:00). Acetaldehyde was the dominant odor compound detected in both the Bonglim Bridge (0.4 ppm) area and Guro Bridge area (0.867 ppm), with concentrations more than twice as high near Guro Bridge. Odor-causing compounds identified by TD-GC/MS indicated a pungent, sulfurous odor in the Guro Bridge area and a musty odor in the Bonglim Bridge area. Conclusions: This study categorizes and analyzes the sources of odor in Dorim Stream in Seoul based on meandering patterns and the distribution of sewage facilities, highlighting the potential odor issues associated with combined sewage systems and sewer junctions and suggesting policy improvements.

This study was conducted to find an odor reducible solution in Hwayang agricultural industrial complex. Civilcomplaints have lasted because of odor caused by recycled plastic producers. In order to understand the emissioncharacteristic and concentration of key odor components, we investigated the complex odor and 17 odorcompounds at 3 sites of five chemical facilities from march to october 2013. The results of complex odor showed8~12 at a boundary of 5 facilities. The results of complex odor showed 6694, 3000, 1442 at an emission (stack)of 3 facilities, which exceeded the emission standard. The highest compound and its concentration of each sitewas different because each facility has different processes and use different raw materials. We suggested thesuitable prevention facility for each company to reduce odor. We analyzed the odor contribution with the emission(stack) point of S, I, B and the inside point of W, J. S plant was Acetaldehyde (45%), I plant was Trimethylamine(32%), B plant was Styrene (35%), W plant was Hydrogen sulfide (42%), J plant was Hydrogen sulfide(41%). An objective of study is odor management area and will apply odor strict emission standards. A suitable preventionfacility should be operated efficiently based on survey data to reduce odor.

열차화장실에서 발생하는 악취저감을 위한 기초연구로서, 무궁화호 내 67개소의 화장실을 대상으로 악취강도를 조사하였으며, 6회에 걸쳐 열차화장실 악취시료를 채취하여 복합악취농도를 조사하였다. 복합악취농도는 악취공정시험법에 제시되어 있는 공기희석관능법을 이용하여 측정하였으며, 악취강도는 직접관능법을 이용하여 조사하였다. 조사결과, 복합악취농도는 희석배수 6에서 30의 범위로 나타났으며 평균 복합악취농도는 17 정도인 것으로 나타났다. 악취강도는 67개의 화장실을 조사한 결과 0도에서 3.3도였으며, 이 가운데 16개소에서는 악취강도가 2.5도 이상으로 높게 나타나 악취저감이 필요한 것으로 조사되었다. This study was carried out to estimate odor emitted from toilets in the Mugunghaw train. Two parameters which are odor intensity and odor concentration are used for odor estimation. Direct olfactory method to observe odor intensity for 67 toilets and air dilution olfactory method to estimate odor concentration for 6 samples were performed. As the results, odor concentration of toilets in trains ranged from 6 OU/m³ to 30 OU/m³, and odor intensity of 67 toilets were varied from 0 degree to 3.3 degree. The results suggest that the odor emitted from the existing toilets should be controlled because odor intensity of 16 toilets exceeded the level of complaint due to odor.

Even though offensive odor control law was enforced in 2005, the civil appeal of odor doesn’t decrease all parts of the country. On Effluent Quality Standard site, the reason why the civil appeal is filed could be the restriction which is regulated by odor concentration(dilution threshold) without considering odor emission. When regulating odor concentration only, the different scenarios were considered and analyzed for diffuse form through odor concentration, stack height and flow rate using AERSCREEN. Oder compounds from the analyzed scenarios were fluctuated by not only odor concentration but flow rate. Therefore, flow rate regulation introduction is necessary because odor concentration regulation of Effluent Quality Standard doesn’t make the civil appeal reduce. Now, Odor Effluent Quality Standard is managed by Effluent Quality Standard like air pollutants in Korea. It means, the concept conversion of Receptor-centric is need for preventing civil appeal and complaint of odor. For the odor management of receptor-centric, workplace emission is regulated in accordance with odor concentration at receptor. but it’s hard to regulate all of workplace respectively because all workplace condition is different each other In Japan, odor diffusion modeling for calculating the causal relationship between receptor and emission is used for the method to figure out the problem. By expanding odor automatic monitoring network that some of local governments have, odor emission management and continues receptor current status analysis are needed to combine and operate for resolving odor problem.
