| Abstract |
For the purpose of examining about seasonal difference in concentration of indoor organic compounds in Korea, 96 houses in the winter and 49 houses in the summer were investigated. Indoor organic compounds level were measured and survey was performed by questionnaire. Indoor organic compounds were monitored with two diffusive samplers. One was a cartridge treated with 2,4-dinitrophenylhydrazine for aldehydes sampling. The other was a passive charcoal tube for VOCs sampling. Two samplers were simultaneously exposed in living room during 24 hours. The main Results were as follows. (1) Both of Formaldehyde and VOCs concentration in the summer are lower than that in the winter. This is because of increasing ventilation rate according to the opening of windows in the summer. (2) Formaldehyde, toluene and ethylbenzene were indicated as the major indoor volatile organic compounds in Korean houses. (3) There were 10 times of deference in concentration level between non-occupied new house and that of post-occupied. (4) There was no significant relation between house type and concentration level. |
