2009-2010年夏季，在南极的乔治国王岛部署了基于聚氨酯泡沫（PUF）盘的被动空气采样器，以调查南极空气中多氯联苯（PCBs）和多溴联苯醚（PBDEs）的水平、分布和潜在来源。大气中∑指示多氯联苯和∑14PBDEs的浓度分别为1.66 ~ 6.50 pg m−3和0.67 ~ 2.98 pg m−3。多氯联苯的同系物以二氯联苯、三氯联苯和四氯联苯为主，而BDE-17和BDE-28是多氯联苯的主要同系物，这可能与远距离大气输运过程有关。然而，靠近南极科考站的采样点显示多氯联苯和多溴二苯醚的大气浓度高于其他采样点，反映了南极科考站可能的当地来源。所有空气样本中均检测到非aroclor同系物PCB-11，空气浓度为3.60 ~ 31.4 pg m−3（平均15.2 pg m−3）。通过对puf盘被动空气采样与大容量空气采样结果的比较，验证了被动空气采样在南极大气中应用的可行性。据我们所知，这项研究是首次在南极大气中使用基于puf盘的被动空气采样器。
Polyurethane foam (PUF)-disk based passive air samplers were deployed in King George Island, Antarctica, during the austral summer of 2009–2010, to investigate levels, distributions and potential sources of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in Antarctic air. The atmospheric levels of ∑ indicator PCBs and ∑14PBDEs ranged from 1.66 to 6.50 pg m−3and from 0.67 to 2.98 pg m−3, respectively. PCBs homologue profiles were dominated by di-PCBs, tri-PCBs and tetra-PCBs, whereas BDE-17 and BDE-28 were the predominant congeners of PBDEs, which could be explained by long-range atmospheric transport processes. However, the sampling sites close to the Antarctic research stations showed higher atmospheric concentrations of PCBs and PBDEs than the other sites, reflecting potential local sources from the Antarctic research stations. The non-Aroclor congener PCB-11 was found in all the air samples, with air concentrations of 3.60–31.4 pg m−3(average 15.2 pg m−3). Comparison between the results derived from PUF-disk passive air sampling and high-volume air sampling validates the feasibility of using the passive air samplers in Antarctic air. To our knowledge, this study is the first employment of PUF-disk based passive air samplers in Antarctic atmosphere.
