Abstract
This study was performed to investigate the distributions of volatile organic compounds and carbonyl compounds at the 120 households in new apartments before occupation. The concentration of toluene, m, p-xylene, formaldehyde, acetone and ethylbenzene dominated as <TEX>$272.81{\mu}g/m^3$</TEX>, <TEX>$98.90{\mu}g/m^3$</TEX>, <TEX>$71.68{\mu}g/m^3$</TEX>, <TEX>$70.58{\mu}g/m^3$</TEX> and <TEX>$49.76{\mu}g/m^3$</TEX>, respectively. The identified compounds by standards occupied 42.5% of the TVOCs, also the concentration of toluene occupied the largest part of the identified compounds as 18.5%. The concentration of formaldehyde and acetone were 43.1% and 42.4% among carbonyl compounds. The indoor/outdoor ratio of the concentration of benzene, toluene, formaldehyde and o-xylene were investigated 1.29, 3.59, 10.76 and 28.74, respectively.
