Abstract
Indoor Volatile organic compounds (VOCs) are classified as known or possible toxicants and odorants. This studycharacterized VOC levels in 11 homes in an area in the capital of Seoul by using two different methods of VOCssampling, which are the active sampling using a thermal sorption tube and the passive sampling using a diffusionsampler. When using the active sampling method, the total target VOC concentration ranged from 41.7 to 420.7 μg/m3 (mean 230.4 μg/m3; median 221.8 μg/m3) during winter and 21.3 to 1,431.9 μg/m3 (mean 340.1 μg/m3; median175.4 μg/m3) during summer. When using the passive method, 29.6 to 257.5 μg/m3 (mean 81.8 μg/m3; median49.4 μg/m3) during winter and 1.2 to 5,131.1 μg/m3 (mean 1,758.8 μg/m3; median 1,375.1 μg/m3) during summer.
Forty-nine VOCs were quantified and toluene showed the highest concentration regardless of the season and thesampling method studied. The distribution of VOCs was relatively varied by using the active method. However,it showed a low correlation with indoor environmental factors such as room temperature, humidity and ventilationtime. The correlation between indoor environmental factors and VOCs were relatively high in the passive method.
In particular, these characteristics were confirmed by principal component analysis.
