Abstract
Recently the problem of indoor air quality in new apartments has become a serious issue. Therefore, this study targets the main causes of Sick House Syndrome caused by VOC (formaldehyde, benzene, toluene, ethylbenzene, xylene, styrene). We obtained the indoor air quality data for the two types of new apartments that comprised 16 units. The results are summarized as follows. 1) The average formaldehyde concentration was $527.3{\mu}g/m^3$, benzene was $1.8{\mu}g/m^3$, toluene was $101.9{\mu}g/m^3$, ethylbenzene was $9.5{\mu}g/m^3$, xylene was $9.4{\mu}g/m^3$, and styrene was $5.5{\mu}g/m^3$. 2) Indoor air quality analysis results showed that the formaldehyde concentration exceeded the recommended standard. However, other concentrations of volatile organic compounds satisfied indoor air quality recommendation standards.
