2009年2月（南极夏季），在南极西部半岛附近的空气中测量了挥发性全氟烷基和多氟烷基化合物。第六：二、八：2和10：2氟调聚物醇（FTOH）是最丰富的化合物，其8：2和10：2 FTOH浓度平均值分别为9.9和7.4 pg m（-3），其次是甲基全氟丁烷磺酰胺（MeFBSA）和磺酰胺基乙醇（MeFBSE）的短链（C-4）化合物，其平均浓度接近3至4 pg m（-3）。甲基/乙基氟辛烷磺酰胺和磺酰胺基乙醇（FOSA/Es）是
Volatile per- and polyfluoroalkyl compounds were measured in air in the vicinity of the Western Antarctic Peninsula during February 2009 (Austral summer). The 6: 2, 8: 2 and 10: 2 fluorotelomer alcohols (FTOHs) were the most abundant compounds with 8: 2 and 10: 2 FTOH concentrations averaging 9.9 and 7.4 pg m(-3) respectively, followed by the shorter chain (C-4) compounds of methyl perfluorobutane sulfonamide (MeFBSA) and sulfonamidoethanol (MeFBSE) with average concentrations of similar to 3 to 4 pg m(-3). Methyl/ethyl fluorooctane sulfonamides and sulfonamidoethanols (FOSA/Es) were
