In this study, the spatial and temporal distribution of odorants in ambient air was investigated at three measurement points in a University campus in Seoul city during a 15 day study period. The concentrations of 12 target analytes designated as malodor compounds by KMOE were measured through time. The highest mean concentration (in ppb unit) was found from NH₃(25.3) followed by styrene (0.51) ＞ acetaldehyde (0.13) ＞ H₂S, propionaldehyde (0.07) ＞ butyraldehyde, isovaleraldehyde, and valeraldehyde (0.06) ＞ DMDS (0.04) ＞ TMA (0.03) ＞ CH₃SH and DMS (0.01). Comparison of odorant data showed fairly strong distinctions across diurnal period, while differences in concentration levels were not clear enough between different sampling locations. The results of correlation analysis showed that the concentrations of DMS and NH₃ were strongly correlated with relative humidity. In addition, most of reduced sulfur compounds (RSC) exhibited strong correlations with each other. When the odorant concentrations were converted into odor intensity, the values were typically found below the odor degree of 1. The odor intensity, if assessed by the maximum values of each compound, were generally in between 1~2 odor degree level (e.g., H₂S, CH₃SH, DMDS, acetaldehyde, and TMA). The results of this study thus show that most odorant species occurred below the threshold value at clean space like a University campus. Hence, more efforts are desirable toward the development of the analytical technique at various concentration levels.
