摘　　要：目的了解大连市某小区居民居室空气中多种挥发性有机物(VOCs)污染现状,为防治VOCs污染对居民健康影响提供依据。方法于2007年8月1—15日在大连市某小区随机选择装修后<0.5a的15户住宅,0.5～1.5a的17户住宅,>1.5～3.0a的21户住宅,在卧室、厨房和室外各设1个采样点,采样时间为24h,采用气相色谱-质谱联用仪测定空气中VOCs浓度。结果装修后0.5a内卧室甲基异丁基甲酮、醋酸丁酯、1,2-二氯乙烷、1,1,1-三氯乙烷、四氯乙烷、己烷和正丁醇的浓度分别为0.60、9.15、3.10、1.00、1.67、1.90和14.50μg/m3;厨房内该7种VOCs浓度分别为0.60、8.10、3.95、1.74、0.85、1.87和12.45μg/m3。其中装修0.5a内室内醋酸丁酯、1,2-二氯乙烷和正丁醇浓度高于装修0.5a以上(P<0.05,P<0.01)。装修1.5a后卧室和厨房空气中甲基异丁基甲酮、1,2-二氯乙烷和正丁醇浓度均高于室外(P<0.05,P<0.01)。该7种VOCs浓度之间存在相关性。结论该小区居室存在VOCs污染状况,居室装修1.5a后仍有多种VOCs浓度高于室外,为预防VOCs对居民健康的慢性危害,采取较长期的室内污染防治措施是非常必要的。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 μg/m3 in the bedrooms; they were 0.60, 8.10, 3.95, 1.74, 0.85, 1.87 and 12.45 μg/m3 in the kitchens. The concentrations of VOCs indoor were still higher than those of outside atmosphere （P〈0.05 or P〈0.01） 1.5 years after decorations. At the same time, a positive correlation was observed among the VOCs （P〈0.01）. Conclusion Under the conditions of the natural ventilation, the concentrations of VOCs in the indoor air were still higher than those of outside air after the decoration.
