Assessment of Organic Compounds Emission from Consumer Products in an Environmental Chamber System

In order to present the scientific information of organic emissions from consumer products available, the current study examined the emissions composition for three different types of consumer products being used in Korea in an environmental chamber: air freshener (AF), mosquito repellents (MSQR), and moth repellents (MTHR). Emission rates were evaluated by determining emission rates of the target compound from the selected products using an electropolished stainless steel (SS) test chamber $(40{\times}25{\times}50cm^3)$. A time-dependent empirical relationship developed in this study agreed well with the test results. As same with the emission concentrations, MSQR exhibited the highest emission rate for all target compounds except for limonene and naphthalene. MTHR ($9,200\;{\mu}g\;h^{-1}$) showed the highest emission rate of naphthalene followed by MSQR ($8,300\;{\mu}g\;h^{-1}$). Moreover, the concentrations in residential bedroom conditions for target compounds emitted from three types of consumer products were estimated. This estimation suggests that the uses of consumer products can elevate indoor levels of target compounds. In particular, any types of the consumer products may increase the indoor level of m, p-xylene.
