(Abstract) Chemical emissions from various Household products are influenced indoor air quality. Accordingly, this study aims to comprehensively evaluate emission characteristics of volatile organic compounds(VOCs) from household product(Aromatic and Insecticide). In this study, Household Deodorizer(Air fresheners) of 26 products; Insecticide of 12 products(Catching fleas of 5 products and Repellents of 7 products) were examined under different experimental conditions using headspace, environmental chamber and filed study. The study includes in Three experiments parts. In the First experiment, 33 Household products were analysed for VOCs using headspace method - gas chromatography/mass spectrometer(GC/MS). For the second experiment, Household Deodorizer(Air fresheners) of 7 gel-type products; Insecticide of 6 products(Catching fleas of 3 products and Repellents of 3 products) were selected for a chamber test, respectively. There were five toxic analysts in the headspace phase of Air fresheners and Insecticide (toluene, benzene, ethylbenzene, and m.p-xylene) which occurred at a frequency of more than 50%. Limonene and linalool, Which are known as unsaturated ozone-reactive VOCs, were detected at a frequency of 58 and 35%, respectively. Also Naphthalene id detected at a frequency of 35%, respectively. The empirical model fitted well with the time-series concentration in the chamber, thereby suggesting that the empirical model was suitable for testing emission. Limonene exhibited the highest emission concentration at air fresheners, and Naphthalene exhibited the highest emission concentration at Repellents and Ethylbenzene exhibited the highest emission concentration at Catching fleas. Each emission concentration was about 133 Times higher for limonene(34.56 mg m-3), Naphthalene(643.51 mg m-3), Ethylbenzene(650 mg m-3). In the third experiment, It experimented from the public facilities and the apartment and the automobile which uses the household products. Result, The mean concentrations of Limonene and Naphthalene were either significantly or slightly higher in indoor with Air fresheners and Repellents than without.
