中文摘要：
利用PUF被动采样技术对珠江三角洲地区大气中多溴联苯醚（PBDEs）进行了为期8周的监测分析。以研究该区域中PBDEs的含量及分布．结果表明。内地采样点PBDEs含量为62-625pg／m^3，平均值210pg／m^3,其中东莞（625pg/m^3）和佛山（560pg/m^3）是PBDEs的高污染地区，工业点源释放可能是该地区PBDEs的主要来源．香港PBDEs含量为92-420pg／m^3,平均值200pg／m^3,其中High st（420pg／m^2）和Kwung tong（325pg／m^3）的PBDEs含量较高，历史上大量PBDEs阻燃剂的使用可能是香港地区大气中PBDEs残留的主要来源．
英文摘要：
The monitoring analysis of 8 week period of polybrominated diphenyl ethers （PBDEs） in the atmosphere of Pearl River Delta region was made using PUF passive sampling technique, to study the PBDEs content and distribution of the region. The inland sampling point PBDEs content was 62-625pg/m^3, with average value of 210pg/m^3, in which Dong Guan （625pg/m^3） and Fo Shan （560pg/m^3） were high pollution regions, the discharge of industrial point source might be the main source of PBDEs in this region. The PBDEs content of Hong Kong was 92-420pg/m^3, with average value of 200pg/m^3, in which the contents in High st （420pg/m^3） and in Kwung tong （325pg/m^3） were high relatively; the use of large amount of PBDEs burning resistive agent in history might be the main source of PBDEs residual in the atmosphere of Hong Kong region.
