| 中文摘要 |
| 分析评价了杭州市办公场所中PBDEs的污染现状、污染特征. 结果表明，办公场所中PBDEs气相和颗粒相总浓度范围为40.66~141.00 pg·m-3，平均浓度为93.22 pg·m-3，是家庭室内、室外浓度的1.87、5.01倍. BDE-47、BDE-99为办公场所中最重要的两种同系物，分别占总浓度的33.29%、31.99%. PBDEs气相浓度是颗粒相的1.34倍，其中BDE-28、BDE-47、BDE-99主要存在于气相中，BDE-153、BDE-183主要存在于颗粒相中. |
| 英文摘要 |
| Pollution Status and characteristics of PBDEs in offices were investigated in Hangzhou. As a result, the total concentration of PBDEs was 40.66-141.00 pg·m-3, and the mean concentration was 93.22 pg·m-3, being 1.87 and 5.01 times as high as those in homes and outdoor. In particle and gas phases, BDE-47 and BDE-99 were the most abundant congeners, which accounted for 33.29% and 31.99% of total PBDEs, respectively. Concentration of PBDEs in gas phase was 1.34 times as high as that in particle phase. BDE-28, BDE-47 and BDE-99 mainly existed in the gas phase, while BDE-153 and BDE-183 mainly existed in the particle phase. |
