초록

Wax is a protectant for floors that is used widely in Korea and is considered an emission source of volatile organic compounds (VOCs) in the indoor environment. This study examined the concentration change of indoor VOCs due to waxing and also due to wiping the floor with an oiled dustcloth. VOCs were identified using a cryogenic concentration/thermal desorption system with capillary GC that utilized a liquid nitrogen cryostat and induction heating. The major components emitted from the waxing were nonane, decane, undecane, $C_2$-benzene, and $C_3$-benzene. The concentrations of nonane were 1,276 $\mu\textrm{g}$/㎥ an hour after wax applications, 832 $\mu\textrm{g}$/㎥ after 3 days, and less than 10$\mu\textrm{g}$/㎥) after 15 days. Another emission source of VOCs in indoor was the oiled dustcloth used for cleaning the floor. The oiled dustcloth gave VOCs concentrations three times higher than the normal undusted floor.
