The purpose of this study is to survey volatile organic compounds(VOC) and indoor emission source of them through field measurements. As a basic survey of VOC, hydrocarbons from C9 to C19 were measured for 3 months, and the relations of concentrations between indoor and outdoor were analyzed. Then VOC were measured in two atriums, and emission sources of them were evaluated by principal component analysis. The results are as follows; 1) The sum of each indoor hydrocarbon concentration was ranged from 30 to 180μg/m^3. Indoor hydrocarbon compounds were primarily consisted of outdoors, but some compounds were considered to be emitted from sources of indoor. 2) Ethylbenzene, xylene, trimethylbenzene, dichlorobenzene, D4 and hydrocarbon were detected at μg/m^3 order in atrium, and total VOC concentrations were ranged from 150 to 300μg/m^3. 3) Ethylbenzene, xylene and dichlorobenzene in A atrium were considered to be emitted from smoking, and ethylbenzene and xylene in B atrium were from insecticide used to plant in atrium.
