摘　　要：为了研究哈尔滨市不同室内空气中多溴联苯醚(PBDEs)的污染,于2011年冬季采集了哈尔滨市12个不同类型的室内空气样品,通过索氏萃取的方式对空气中的PBDEs进行提取,采用GC/MS进行定性和定量分析.结果表明,Σ12PBDEs的平均质量浓度为5.33 pg/m3,其中BDE-47是主要的污染物,其平均质量浓度为2.83 pg/m3,其次是BDE-28(1.85 pg/m3).不同类型的室内空气比较发现,实验室空气中PBDEs的质量浓度最高,家庭空气中PBDEs的质量浓度最低.主成分分析表明,哈尔滨室内空气中PBDEs的来源主要是商用五溴和商用八溴.通过计算空气吸入的PBDEs的暴露分析表明,婴儿的PBDEs暴露量最高,说明婴儿受PBDEs的潜在危害较大.In order to study the pollution of polybrominated diphenyl ethers （PBDEs） in in-door air of Harbin , 12 different types of indoor air samples were collected in the winter of 2011.Soxhlet extraction method was used for the extraction of PBDEs in Air samples .PB-DEs were analyzed by GC/MS for qualification and quantification .The results indicated that the average concentration for Σ12 PBDEs was 5.33 pg/m3 , and BDE-47 was the dominated compound with the average concentration of 2.83 pg/m3 , followed by BDE-28 （1.85 pg/m3 ） .For the comparison with concentrations among different types of indoor environment , the highest and lowest concentrations of PBDEs were found in laboratory and in home .Prin-cipal component analysis showed that the main sources of PBDEs in the indoor air in Harbin were Penta-BDE and Octa-BDE commercial products .Air inhalation exposure estimation showed that infants had the highest exposure to PBDEs , which indicated the highest risk for infants .
