Abstract
This study is for investigation of indoor conditions with air contamination after occupation 120 households in brand-new apartments by measuring the concentration of VOCs and carbonyl compounds. It has been found that TVOC (total volatile organic compounds; TVOCs) were $688.61{\mu}g/m^3$ after moving in. And formaldehyde, toluene, m, p-xylene, acetone and ethylbenzene were $158.56{\mu}g/m^3$, $146.58{\mu}g/m^3$, $69.28{\mu}g/m^3$, $63.80{\mu}g/m^3$ and $29.65{\mu}g/m^3$, respectively. The mean concentrations of indoor air pollutants tend to decrease along an increase dwelling period. But, the mean concentration of d-limonene increased from 2 months to 10 months. Also, toluene, ethylbenzene, m, p, o-xylene amounted to 38.8 % among VOCs studied, this ratio tend to decrease along with and increased dwelling period.
