Study on Emission Characteristics of Designated Odor Substances by Emission Source in Busan Industrial Complex Area Using SIFT-MS

In this study, the emission characteristics of designated odor substances emitted from 11 odor emission sources in the industrial complex area were investigated using SIFT-MS for efficient management of malodor emission facilities in the industrial complex area of Busan.The concentration distribution, odor activity value (OAV), odorous contribution rate (OCR), and odor intensity (OI) of designated odorous substances for each emission source were identified.By creating a pollution rose map, we identified the direction and distance affecting the measurement point and secured basic data for management and reduction of odor in the industrial complex area.The concentrations of acetaldehyde and trimethylamine were high in wastewater treatment companies.High concentrations of butanoic acid were detected in food manufacturers and feed manufacturers that handle something related to food.The sum of the concentrations of 20 designated odor substances was highest (4.732 mL/m 3 ) at the SS-3 site of the wastewater treatment company, followed by SS-2 > GJ-2 > SS-1.In the case of OAV of designated odor substances, it was the highest (5352.9mL/m 3 ) at SS-3 site, followed by SS-2 > GJ-2 > SH-1.Based on OVA, the OCR of trimethylamine among amines, methyl mercaptane among sulfur compounds, acetaldehyde among aldehydes, and butanoic acid and valeric acid among organic acids was high.The result of odor intensity was that TMA in wastewater treatment companies and methyl mercaptane in food waste disposal company was high.As a result of creating a pollution rose map, the SH-3 site which is located in precision machinery facilities showed a high concentration of odorous substances when the north wind blew.In the case of the SH-4 site, a food manufacturer, it was greatly affected by the southeast wind blowing from manufacturers are scattered.At GS-1 site, casting manufacturing business, the high concentration was observed when the northeast wind blew from the industrial complex area, which is in the opposite direction to the sea.
