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 x m(-3), and the mean concentration was 93.22 pg x 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.
对杭州办公室中多溴二苯醚的污染状况和特征进行了调查。结果显示，多溴二苯醚的总浓度为40.66 - 141.00 pg x m(-3)，平均浓度为93.22 pg x m(-3)，分别是家庭和室外浓度的1.87倍和5.01倍。在颗粒相和气相中，BDE - 47和BDE - 99是含量最高的同系物，分别占多溴二苯醚总量的33.29%和31.99%。气相中多溴二苯醚的浓度是颗粒相的1.34倍。BDE - 28、BDE - 47和BDE - 99主要存在于气相中，而BDE - 153和BDE - 183主要存在于颗粒相中。
