ABSTRACT
Objective To understand the pollution status of indoor volatile organic compounds(VOCs) and to provide evidence for preventing the adverse effects of them on resident health.Methods According to the different times of the house decoration, 53 residents were randomly selected from a district of Dalian.Air was sampled in the bedrooms, the kitchens and the outdoors for 24 h by sampling tubes which were activated by activated carbon and the concentrations of VOCs were analyzed by GC-MS/ SIM.Results The concentrations of VOCs indoor were higher at the half year after decoration.The concentrations of methyl isobuthyl ketone, butyl acetate, 1, 2-dichloroethane, 1, 1, 1-trichlo-roethane, tetrachlorocarbon, hexane and buthanol were 0.60, 9.15, 3.10, 1.00, 1.67, 1.90 and 14.50 ?g/m3 in the bedrooms;they were 0.60, 8.10, 3.95, 1.74, 0.85, 1.87 and 12.45 ?g/m3 in the kitchens.The concentrations of VOCs indoor were still higher than those of outside atmosphere(P
