In this study, emission characteristics of volatile odorant species released from urine samples were investigated in relation to two key variables: [1] storage conditions before sampling and [2] incubation conditions during sampling. To this end, 20 offensive odorants were quantified by four different analytical systems and then sorted according to seven functional groups. It is indicated that benzene (B), styrene (S), isobutyl alcohol (i-BuAl), butyl acetate (BuAc), butyraldehyde (BA), isovaleraldehyde (IA), and valeraldehyde (VA) did not contribute to urine odor because their concentration levels were measured below detection limits in all samples. On the other hand, emission concentrations of toluene (T), methyl ethyl ketone (MEK), methyl mercaptan ($CH_3SH$), carbon disulfide ($CS_2$), and ammonia ($NH_3$) were generally higher than other compounds. In terms of odor intensity (OI), $CH_3SH$ and $NH_3$ showed the largest OI values in the range of 2~4. According to t-test (storage approach and urine temperature), the results of T, $CS_2$, and $NH_3$ were statistically distinguished from each other in terms of differences in sampling temperature. Likewise, the emissions of certain odorants from urine samples were affected by changes in sample treatment conditions to a degree.
