This study is for investigation of indoor conditions with air contamination after occupation 120households in brand-new apartments by measuring the concentration of VOCs and cabeen found that TVOC (total volatile organic compounds; TVOCs) were 688.61 g/m3 after moving in. Andformaldehyde, toluene, m, p-xylene, acetone and ethylbenzene were 158.56 g/m3, 146.58 g/m3, 69.28 g/m3, 63.80 g/m3 and 29.65 g/m3, respectively. The mean concentrations of indoor air polutants tend to decreasealong an increase dwelling period. But, the mean concentration of d-limonene increased from 2 months to 10months. Also, toluene, ethylbenzene, m, p, o-xylene amounted to 38.8 % among VOCs studied, this ratio tendto decrease along with and increased dwelling period.
