This study was conducted to identify status of odor managing zones in incheon metropolitan city. There are four odor managing zones in incheon ; Namdong industrial complex, Seobu industrial complex, Seoknam-Wonchangdong industrial complex, Baekseok-Oryudong area. Each zone with 16 sampling sites consisted of three parts. One was inner area (1-1~1-4 site) and another was boundary area (2-1~2-4 site) and the third was outer area (3-1~3-8 site). We analyzed quarterly 18 items of odor pollutants in order to investigate air quality of odor managing zones during 2006. Data of inner area was higher than that of boundary or outer area and concentration of odor pollutants of night was higher than that of day. Overall results of this study showed that concentration of odor pollutants in some sampling sites of boundary and outer area was too low (about ND). Especially ambient hydrogen sulfide of inner area (1-1 site) and boundary area (2-1 site) in baekseok-oryudong odor zone were 0.82 ppm and 0.55 ppm respectively due to landfill gas.

In this study, QA/QC (quality control/quality assurance) data of reduced sulfur compounds from several institutes were obtained and compared based on the Korean standard method for off-odor. From the results, attempts were made to optimize the analytical conditions and improve the measurement reliability of reduced sulfur compounds analyses from detailed CF/TD and GC/PFPD information. Analysis results (minimum detection limit, precision, recovery rate) of reduced sulfur compounds based on the each analytical condition corresponded with the Korean standard methods for off-odor. Therefore, we expect that we could execute the exact analysis if we use the analytical condition of CF/TD and GC/PFPD in this study
