| 摘 要： | 分析评价了杭州市家庭室内空气中多溴联苯醚(PBDEs)的污染现状及特征.结果显示:杭州家庭客厅空气中气相和颗粒相PBDEs的总浓度平均值分别为52.57 pg·m-3,范围为21.37～83.47 pg·m-3、卧室浓度为43.78 pg·m-3,范围为28.72～58.75 pg·m-3,BDE-47和BDE-99是家庭室内空气中最重要的两种单体,占总浓度的62.75％.室内空气中气相PBDEs浓度是颗粒相的1.49倍.高层建筑中的PBDEs浓度与低层建筑差别不大,均处于较低水平.PBDEs的理化性质、环境条件是影响其气固分配的重要因素. |

| Abstract: | Concentrations and characteristics of gas-phase and particle-phase PBDEs in indoor air of homes in Hangzhou were investigated. The concentrations of total PBDEs in living rooms and bedrooms were in the range of 21.37~83.47 pg·m-3 (with a mean value of 52.57 pg·m-3) and 28.72~58.75 pg·m-3 (with a mean value of 43.78 pg·m-3), respectively. BDE-47 and BDE-99 were the major pollutants among the congeners of PBDEs, which accounted for 62.75% of total PBDEs. Gas-phase concentration of PBDEs was 1.49 times that of PBDEs in particle phase. Concentrations of PBDEs in indoor air were low. There was no significant difference in the concentrations of the congeners of PBDEs in indoor air between high-rise and low-rise buildings. Physicochemical properties and environmental conditions were important factors to affect the concentration distribution of PBDEs in gas and particle phases. |
