摘　　要：[目的]了解居民居室空气中5种主要污染物的污染现状,为防治室内污染物对居民健康影响提供现况调查依据。[方法]在大连市泡崖小区,随机选择居室装修后不同时期的居民53户,用活性碳活化过的空气采样管24h采样,通过气相色谱质谱联用仪分别测定居民卧室、厨房以及室外空气中多种污染物的浓度。[结果]装修后1年内的卧室空气中甲醛、二氧化氮、甲苯、二甲苯、苯的浓度分别为0.035 mg/m3、0.031 mg/m3、18.7μg/m3、7.5μg/m3、4.2μg/m3;上述5种污染物在厨房空气中分别为0.030 mg/m3、0.042 mg/m3、16.7μg/m3、7.1μg/m3、2.9μg/m3,均明显高于室外浓度(P<0.05或P<0.01)。即便是装修3年以上的居室,其空气中的甲醛和二氧化氮的浓度仍然为室外的2.1倍和2.2倍以上。相关性分析表明,除了二氧化氮以外其他4种污染物浓度之间存在一定相关性(P<0.01)。[结论]对于装修3年以上的居室,即便在保持经常通风条件下其居室空气中的甲醛和二氧化氮浓度仍然高于室外浓度,预防居室装修产生的污染物对居民健康的慢性有害影响,将是一项长期的措施。[ Objective] This investigation is to determine the status of 5 indoor air pollutant concentrations and to provide scientific advice for preventing residents from adverse health effects. [ Methods] According to different time after citizen accommodation decorated, 53 households were randomly selected in Paoya district of Dalian. Air was sampled in bedroom, kitchen and outdoor of the housholds for 24 hours by sampling tubes which were activated by activated carbon and concentrations of 5 pollutants in these air samples were determined by GC - MS. [ Results] In one year after decoration, the concentrations of formaldehyde, nitrogen dioxide, toluene, xylene and benzene in the bedroom were 0. 035 mg/m^3, 0. 031 mg/m^3, 18.7 μg/m^3, 7.5μg/m^3 and 4.2 μg/m^3 respectively. In the kitchen, their concentrations were 0. 030 mg/m^3, 0.042 mg/m^3 , 16.7 μg/m^3 , 7.1 μg/m^3 and2.9μg/m^3 , respectively. The concentrations of these pollutants in the bedroom （P 〈 0.05 ） and kitchen （P 〈 0.01 ） were significantly higher than those in outdoor sampled air. Even if the time after fitment was over 3 years, the concentrations of formaldehyde and nitrogen dioxide in inside were 2.1 and 2.2 times higher than those in outside. Results of correlation analysis showed that there was correlation between concentrations of the 4 pollutants （P 〈 0.01 ） except nitrogen dioxide. [ Conclusion ] These results indicate that prevention against chronic adverse effects of indoor pollutants by fitment on resident health is a long - term issue.
