This study examines the correlation between livestock odor civil petitions and the establishment of malodor control areas in Jeju Special Self-Governing Province, focusing on swine farms where numerous civil petitions regarding malodors have been received. After the designation of the malodor control areas, high odor concentrations occurred in Aewoleup and Jocheon-eup, and the odor concentration decreased in other areas. The number of civil petitions shows a consistent annual trend, with increased petitions from March, peaking during summer (July and August), and decreasing from September into winter. In Jeju-si, there were many civil petitions in Hallim-eup and Aewol-eup where there were many malodor control areas. However, in Seogwipo-si, there were also many civil petitions in Pyoseonmyeon, where there is no malodor control area. Additionally, we compared the average multiple of compound malodors and the rate of exceeding the maximum allowable emission level for compound malodors with the number of livestock malodor civil petitions to assess the actual state of malodors. The results reveal a stronger correlation between the number of civil petitions and the rate of exceeding the compound malodors allowable emission level than the average multiple for compound malodors. These findings provide valuable insights into addressing livestock odor concerns and enhancing malodor control measures in Jeju Island.

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 t he 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.

The relation between civil appeals of odor in major regions of Incheon area and the operation of odor management area was examined for recent several years. From the studies the civil appeals of odors in the odor management area were closely related and estimated to decrease gradually with the tendency of civil appeals of odors neighboring and outside the odor controlled regions showed the tendency of increase in the Incheon area. To explain those phenomena detailed analysis was conducted with quality analysis of those area.

The tendency of regional civil appeals and characteristics were investigated in Incheon area and the consciousness of citizen related with effective odor was analyzed from questions in this study. The tendency of regional civil appeals were different and the consciousness of citizen with the conception and kind of odors were diverse with each regions. The improvement methods of odor management were suggested from those results.

The malodor control law enacted in 2005, regulated malodor substances ansmg from factory or service industry. In this work, an attempt is made to understand the actual conditions of malodor occurrence for types of industry and to settle trouble for a odor complaint. The odor concentration unit (o.u/㎥) of each major odor emitting industry was actualized by the indirect olfactory method including air dilution sensory test method in Korea. The industry that malodor complaint originate mainly were Chemical manufacturing industry, Waste disposal facilities and Livestock farming. As the results, Livestock farming were measured from 3 o.u/㎥ to 30 o.u/㎥ in the source boundary site, Waste disposal facilities were measured from 300 o.u/㎥ to 669 o.u/㎥ in the stack and Chemical manufacturing industry was analyzed from 300 o.u/㎥ to 1442 o.u/㎥ in the stack. Sampling of the source boundary site was demand the reform because malodor state at the field not expressed properly. In oder to solve such problem, propose total odor emission rate (T.O.E.R) introduction.

정부에서는 분리수거에 의한 폐기물 감량화를 유도하기 위하여 1995년부터 전국적으로 종량제를 실시하고 있으나, 수거 및 운반단계에서 발생되는 문제(폐기물 방치에 따른 악취 및 미관저해 등 환경위생적인 측면, 수거차량 이동에 따른 교통안전 등의 문제)를 크게 개선하지 못하고 있다. 이러한 문제를 해결하고자, 생활폐기물 수거운영방식으로 이미 유럽 및 일본 등에서 운영되고 있는 자동집하시스템이 도입되고 있다. 대전광역시는 서구 도안동에 신도시를 조성하면서 친환경 도시환경 조성과 쓰레기수거 경비 절감을 위해 총사업비 927억원을 투입해 자동집하시스템인 크린넷을 설치하여 운영하고 있으나, 제1집하장은 수변공원내에 주거지역과 근접하고 있어 집하장 주변에서 악취에 대한 민원이 많이 발생하고 있다. 제1집하장 주변 악취 민원해결을 위해서 기존의 악취방지시설을 보완하여 운영하고 있으나, 효과적인 대안이 수립되지 않은 실정이며, 현재 악취방지시설은 약액세정법으로 운영되고 있어 새로운 약품의 추가 주입과 기존 주입약품과의 주입량 비율을 조정함으로써 부지경계에서의 측정값은 배출허용기준 15이하는 충분히 만족하지만 큰 효과는 없어 이에 대한 민원을 해결하고자 한다. 악취는 감각공해로 사람마다 악취의 강도를 느끼는 정도가 다른 특징이 있어 민원소지가 많으므로 악취는 배출허용기준을 만족하더라도 복합악취희석배수 만큼 악취가 발생된다는 결과를 의미하므로 악취가 전혀 발생되지 않게 처리하는 방법은 기술적 한계와 더불어 과다한 소요비용이 발생될 수 있다. 따라서 악취를 현재보다 줄이기 위한 방법적용은 기술적 부분과 비용적 부분이 동시에 검토되어야 하며 다음과 같은 방안을 제시할 수 있다. 1) 기존에 설치되어 있는 악취방지시설의 운전조건 수정을 통해(일반 물세정이 아닌 약액세정을 실시, 일반 활성탄을 첨착활성탄으로 교체) 보다 높은 악취제거 효율을 기대하고, 2) 기존 방지시설 운전조건을 개선한 후에도 사업장 주변에서 악취민원이 발생한다면 최종배출가스를 하수 차집관로로 유입하여 처리하도록 하며, 3) 장기적인 방안으로 기존의 악취방지시설로 악취문제를 해결하기 어렵다면 신규 악취방지시설(촉매연소)을 설치할 수 있다.

5 public complaint areas against odor in Changwon Industrial Complex were selected and investigated to clear up the cause of the complaint. 16 companies operated in public complaint areas were visited and had a grip of their situation about odor generation and treatment. Two samples at it's site boundary of each company were taken to measure complex odor unit. Complex odor unit at the site boundary of investigated companies in the public complaint areas, for the most part, exceeded standard(odor unit 20) in industrial area. It was due to that this area was not designated as odor control region and that there are also many problems in current laws of Odor Protection Act, Air Quality Act and regional legislation. Accordingly, It will be necessary to revise the related legislation, to organize governance, to financially support the improvement of environmental facilities and to enforce guidance and the regulation rigidly for the odor emission reduction in Changwon Industrial Complex.

We studied the relationship between a civil affair occurrence of bad smell and meteorological conditions around Seongseo district for recent 2 years. The results were as follows; (1) The civil affair occurrence days of bad smell were concentrated from May to August. (2) Daily mean temperatures were mostly 20～28℃ and daily mean relative humidities were 60～80%. (3) Wind speeds were mostly less than 2m/s(75%), and wind directions were southerly winds(50%). It was hardly occurred for relatively well-ventilated conditions in cases of wind speeds 2m/s over. And the Lagrangian particle dispersion model were used to figure out the transport route in a civil affair occurrence days of bad smell. It was found that the south-western winds transported the bad smelling materials from Jungni-dong(the place of source) to the housing complex located along a piedmont district.
