| 摘要: |
| 齐齐哈尔富拉尔基区为典型的国家重工业集中区域，为研究其大气中多溴联苯醚（PBDEs）的质量浓度水平、污染特征和气/粒分配规律，分别在其下风向和上风向采集大气颗粒相和气相样品，对PBDEs的质量浓度进行测定.结果表明，大气中PBDEs总质量浓度为13.9~102 pg·m-3，平均值为53.6 pg·m-3，BDE-209是质量浓度最高的同系物.来源分析表明，PBDEs主要来源于商用五溴联苯醚和十溴联苯醚的使用.由log KP和log pLo线性回归得到的斜率均高于平衡状态理论值-1，说明大气中的PBDEs气粒分配未达到平衡状态.采用Junge-Pankow吸附模型和Harner-Bidleman吸收模型对PBDEs颗粒态百分比（φ）进行了模拟，结果均高于实际值.

| Abstract: |
| Fularji district of Qiqihar is a typical heavy industry district in China. Gas and particle phases air samples were collected using active air sampler at upwind and downwind of the district in order to study the occurrence, pollution characteristic, and gas/particle partitioning of polybrominated diphenyl ethers (PBDEs). The results indicated that the total concentration (gas plus particle phases) of PBDEs ranged from 13.9 to 102 pg·m-3 with the mean concentration of 53.6 pg·m-3, and BDE-209 was the dominant congener. According to the results of source analysis, PBDEs in air were mainly originated from Commercial Deca-BDEs and Commercial Penta-BDEs. The slopes obtained from the linear regression between log KP and log pLo were lower than the theoretical value of -1, suggesting the non-equilibrium between gas and particle phases. The particle bound fraction (φ) values were modeled using the Junge-Pankow Adsorption Model and the Harner-Bidleman Absorption Model. The values of φ from both the two models were overestimate compared to those obtained from field measurement.
