极地地区由于地处偏远，没有受到重大的人为影响。然而，某些污染物可以通过大气和/或海洋环流输送到那里。本文通过对有机磷酯在极地的分布、来源和迁移方面的文献综述，对极地环境中有机磷酯的研究现状进行了综述。目前对OPEs的研究揭示了两个极地地区的重大人为影响。除了预期在北极发生的情况外，在距离海岸650公里的南极冰盖上也发现了OPE，由于寒冷的气候保留，高海拔地区的OPE浓度较高。内陆南极洲的OPEs的直接来源可能是围绕大陆的南大洋，那里的气溶胶和海水中的OPEs浓度与欧洲北极的偏远地区相当。开放水域气溶胶OPEs与海流表面涡的正相关性表明，这些化合物可能在海流中传输和积累。南极洲绕极流将它们聚集在南极洲的边缘海。引用文献：程文辉，Blais JM，谢振强，等.极地对有机污染物有机磷酯（OPEs）的响应，综述。Adv Polar Sci，2017，28（1）：13-22，doi：10.13679/j.advps.2017.1.00013
Polar regions are free from major anthropogenic impact due to their remoteness. However, certain pollutants can be transported there via atmospheric and/or oceanic circulations. Here we present an overview of current research on organophosphorus esters (OPEs) in polar regions by reviewing the literature on distribution, source and transport of OPEs. Current research on OPEs reveals significant anthropogenic influences in both polar regions. As well as the expected occurrence in the Arctic, OPEs were found on the Antarctic Ice Sheet up to 650 km from the coast, and the OPE concentrations were higher at high elevation due to cold climate retention. The immediate source of OPEs for inland Antarctica might be the Southern Ocean surrounding the continent, where OPEs in aerosols and seawater showed comparable concentrations to remote areas in the European Arctic. A positive correlation between aerosol OPEs in the open water and the surface vortex of ocean currents indicates that these compounds may be transported and accumulated in the ocean currents. The Antarctica Circumpolar Current accumulates them in the marginal seas of Antarctica. Citation: Cheng W H, Blais J M, Xie Z Q, et al.
