여수국가산단 및 주변지역 악취발생 원인조사 = Investigation on the Cause of Odor in Yeosu National Industrial Complex and Its Surrounding Area

다국어 초록 (Multilingual Abstract)

The purpose of this study is to understand the current status and cause of the distribution of odor substances in the Yeosu National Industrial Complex and its surrounding areas. Samples were analyzed by collecting 90 samples at dawn, daytime and night from a total of 15 points, 9 points in the management area, 2 points in the boundary area, and 4 points in the affected area. The analysis items include 5 meteorological factors, complex odor, 22 types of the designated odors and other Volatile Organic Compounds (VOCs). At the MA3 (Fig. 1) point in the management area, the strict emission allowance standard for complex odors was exceeded three times, Ammonia, two types of sulfur compounds, two types of aldehydes, and six types of VOCs were detected, but they were within the standard. As a result of by calculating the odor contribution, the contribution of 74.9 % or more was found at the point where butyraldehyde was detected. Therefore, in order to prevent odors at the Yeosu Industrial Complex, measures to reduce aldehydes with high odor contribution should be prioritized, and it is necessary to simultaneously investigate through real-time harmful atmospheric measurement vehicles. Based on the contents presented in this study, if the system and policies reflecting the results of the odor occurrence survey of Yeosu National Industrial Complex and surrounding areas are supplemented, the odor environment of Yeosu National Industrial Complex will be sufficiently improved.
