초록

This study was undertaken to determine the concentrations of 15 aldehydes in air samples collected from 21 households including 9 atopy patient's homes and to assess the extent of exposure and risk for an individual due to inhalation. Of all the aldehydes identified in both indoor and outdoor environment, formaldehyde and acetaldehyde were the most abundant aldehydes, which were occupied $60\%\;and\;17\%$ of total amount, respectively. The geometric mean concentration of formaldehyde and acetaldehyde in indoor air were $170.5\pm1.9\;{\mu}g/m^3\;and\;47.3\pm1.5\;{\mu}g/m^3$, respectively. There existed a strong correlation between formaldehyde, acetaldehyde and other aldehydes. And the ratio of indoor and outdoor concentrations (I/O) exceeded 1.0 for almost every measured aldehydes except m-tolualdehyde... No associations were found between the level of aldehydes and either housing characteristics or living habits in most of the samples with only a few exception. And the concentrations of all aldehydes indoor air between atopy patient's homes and control homes were not significant(p>0.05). Formaldehyde and acetaldehyde exposures and risks were estimated by using the inhalation unit risk, mean concentrations and the 95th percentiles, and which were $2.6\times10^{-3}\;and\;1.1\times10^{-4}$, respectively. The mean and the 95th percentile risk estimates were 25 times higher for formaldehyde than for acetaldehyde in homes.
