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40.66~141.00Pg·m^-2,平均浓度为93.22Pg·m^-2,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.
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.
