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 annual number of odor complaints increased about 10 times over 14 years from 4,302 in 2005 to 40,854 in 2019, in Korea. Especially, livestock facilities account for more than 50% of the odor complaints and the swine farms account for the most odor complaints among livestock. It is therefore necessary to manage swine farms as the major odor emission source. In this study, a real-time odor monitoring system equipped with PTR-TOF-MS (proton transfer reaction time-of-flight mass spectrometric) was used to measure the odorous substances in two swine farms. Odorous substances emitted from outlets were sampled and measured at the two types of swine farms. In addition, the boundary spots were designated as measurement points. As a result, the rankings of the odorous substances in order, from highest to lowest, were ammonia, acetaldehyde, methyl mercaptan, fatty acids, etc. and the level of odor intensity was 0.8-4.4 at the outlet of the swine farms. The concentration at the boundary decreased between 1/100 ~ 1/10000 compared to the concentration emitted from outlets. Base on the results of evaluating odor activity values, Skatole and p-Cresol were estimated as major odor substances in swine farms.

2019년 3월 27일 경기도 고양시 일산동구 장항동에 위치하는 일산호수공원에서 일광욕 중이던 외래거북 한 개체가 발견되었다. 발견된 개체의 배갑 색, 배갑 중앙의 무늬, 머리 옆면의 무늬, 등껍질의 형태를 근거로 서부비단거북 (Chrysemys picta bellii)임이 확인되었다. 근처에는 서부비단거북이 아닌 외래거북들이 일광욕하고 있었다. 본 논문에서는 국내 야생에서 처음으로 확인된 서부비단거북의 관찰 사례를 보고하였다. 다양한 외래거북들이 국내 생태계에서 지속적으로 발견되고 있으나 그 실태가 잘 알려지지 않고 있다. 따라서 외래생물의 효과적인 관리를 위해서는 지속적인 조사와 보고가 있어야 할 것이라 판단된다.

We conclude if Jeju Peace Island for Koreas 2018 gets international awareness from participants in the spheres of Peace Island Education & Tourism Welfare Model at the Grass Roots Level, it will contribute to institutionalization of both peace island and welfare tourism. In addition, if Jeju government supports the financial budget for the establishment of a Jeju Peace University or a Jeju Environmental University, our efforts might include an impetus to create and operate a Jeju Peace University or a Jeju Environmental University based on collaborative Jeju Peace Studies in Korea and internationally in the nearer future. Of course, we believe that, through this kind of collaborative leadership, a vision of a Nonviolence Korea “Jeju Peace Island for two Koreas” might serve as a buffer zone potentially approved by the Six Nations in the Asia Pacific region in 2019.
