ANALYSIS OF ALDEHYDES IN THE INDOOR ENVIRONMENTS OF ULSAN
This study analyzes aldehyde concentrations in the indoor environments of Ulsan, a typical industrial city in Korea during the fall and summer seasons. The indoor air samples were collected from 8 classified indoor environments which have different characteristic of aldehyde sources and human activities. The aldehyde air samples of 84l were collected from a center of the classified indoor environments and their outdoors using 2,4-DNPH (2,4-dinitrophenylhydrazine)-silica cartridges, attached O3 scrubber to remove O3 in front of the cartridges, and personal air sampling pumps during the summer seasons (56 samples) and the fall seasons (43 samples). Summer concentrations of formaldehyde, regulated as a carcinogenic suspecting compound, were much higher than the fall ones. However, there was no significant difference in acetaldehyde and acrolein concentrations between the summer and the fall. The highest concentrations of formaldehyde, acetaldehyde, and acrolein were identified in meat restaurants followed by smoking houses and apartments. The average concentration ratio between formaldehyde and acetaldehyde was about 2.9 in the summer and 1.5 in the fall. A linear relationship between formaldehyde and acetaldehyde concentrations during the fall (r=0.64) was higher than that of the summer (r=0.5). This study also found that there are strong linear relationships between aldehyde concentrations.
