Five kinds of odorous aldehyde were investigated at industrial complex in Busan. Samples were collected by DNPH cartridge at 24 work places, 81 samples in 44 sites, and analysed by HPLC/UV system. Acetaldehyde was detected in 78 samples with range of 1.2~299.7 ppbv. Propionaldehyde, butyraldehyde, n-valeraldehyde and i-valeraldehyde were detected in 7 samples, 11 samples, 2 samples and 9 samples, respectively. Measured concentration of propionaldehyde, butyraldehyde, n-valeraldehyde and iso-valeraldehyde were ranged 14.8~74.1 ppbv, 1.6~132.0 ppbv, 11.7~13.3 ppbv and 113.9~8858.9 ppbv, respectively. Among total analysed samples, 15 samples were over than degree 3 of calculated odor intensity. All of i- Valeraldehyde detected samples were showed over than degree 3. The work places subsisted aldehydes with high concentrations were related with leather-factory wastes disposal plant, leather, feedstuff, producing synthetic seasoning and textile mill.
