南极洲是评估持久性有机污染物持久性和远距离大气迁移的重要研究区域。在这项研究中，XAD-树脂被动空气采样在中国长城站附近，南极洲，在2009-2010年为期一年的采样期。空气中多氯联苯的浓度很低，总浓度为26.74-45.08 pg m−3。多氯联苯分布以四氯联苯、三氯联苯和二氯联苯为主，表明南极大气中的污染物主要来自LRAT。中国长城站附近的采样点没有显示出比其他地点更高的多氯联苯水平，这表明与长城站有关的多氯联苯来源可以忽略不计。PCB-11是一种非多氯联苯同系物，与其他多氯联苯同系物相比，它有特定的来源。在所有空气样本中都发现了PCB-11，平均浓度为1.22 pg m−3。据我们所知，这项研究是第一次调查PCB的水平和分布在中国长城站，南极洲周围的大气。
Antarctica is an important research region for assessing persistence and long-range atmospheric transport (LRAT) of persistent organic pollutants (POPs). In this study, XAD-resin passive air sampling was conducted near the Chinese Great Wall Station, Antarctica, during a one-year sampling period in 2009–2010. The air concentrations of polychlorinated biphenyls (PCBs) were at a very low level, with total PCBs in the range of 26.74–45.08 pg m−3. PCB profiles were dominated by tetra-PCBs, tri-PCBs and di-PCBs, indicating LRAT was responsible for the pollutants in the Antarctic atmosphere. The sampling site near the Chinese Great Wall Station did not show higher PCB levels than the other sites, suggesting that PCB sources associated with the Great Wall Station were negligible. PCB-11 is a non-Aroclor congener, which has specific sources compared to other Aroclor PCB congeners. PCB-11 was observed in all air samples, with an average concentration of 1.22 pg m−3. To our knowledge, this study is the first investigation of PCB levels and distribution in the atmosphere around the Chinese Great Wall Station, Antarctica.
