통계분석을 이용한 아파트내 휘발성유기화합물의 환경인자 분석

The aim of this study is to understand the characteristics of volatile oranic compounds (VOCs) and provide information about the present Indoor Air Quality (IAQ) at residential apartments. All samples were collected in 60-min interval using the tenax absorption trap between May, 2011 and February, 2012. And the effects of environmental factors such as temperature, humidity and construction characteristics were analyzed in relation to the measured concentrations. The results of this study showed that the mean concentration of VOCs was lower than the Ministry of the Environment’s standards for maintenance of indoor air quality. The correlation analysis showed that ethylbenzene and xylene (r=0.916, p＜0.01), toluene and ehtylbenzene (r=0.810, p＜0.01), toluene and xylene (r=0.803, p＜0.01) and toluene and styrene (r=0.588, p＜0.01) were significant. The result of regression analysis was found that the influenece factors associated with the concentration of VOCs were the age and location of the apartment, remodeling, the temperature and the season.
