由于使用含全氟烷基和多氟烷基物质的水性灭火泡沫，消防训练设施是向附近环境排放全氟烷基和多氟烷基物质的潜在来源。在瑞典斯德哥尔摩阿兰达机场的消防训练设施附近，研究了全氟烷基羧酸盐（PFCAs）、全氟烷基磺酸盐（PFSAs）、全氟辛烷磺酰胺（PFOSA）和6：2氟调聚物磺酸盐（FFSA）的多介质分布。欧洲鲈鱼（Perca fluviatilis）的PFASs全身负荷为334 +/- 80 μ g绝对值，分布如下：性腺>肝脏接近肌肉>血液>鳃。对于PFCA和PFSA，每增加一个CF 2部分，生物富集系数（BCF）和沉积物/水分配系数（K-d）分别增加0.6-1.7和0.2-0.5个log单位。2009 - 2013年水体中PFAS浓度没有显著下降趋势（p > 0. 05），表明斯德哥尔摩阿兰达机场可能是PFAS长期污染附近环境的重要来源。(C)2014爱思唯尔有限公司版权所有。
Fire training facilities are potential sources of per- and polyfluoroalkyl substances (PFASs) to the nearby environment due to the usage of PFAS-containing aqueous fire-fighting foams (AFFFs). The multimedia distribution of perfluoroalkyl carboxylates (PFCAs), perfluoroalkyl sulfonates (PFSAs), perfluorooctanesulfonamide (PFOSA) and 6:2 fluorotelomer sulfonate (FFSA) was investigated near a fire training facility at Stockholm Arlanda Airport in Sweden. The whole body burden of PFASs in European perch (Perca fluviatilis) was 334 +/- 80 mu g absolute and was distributed as follows: Gonad > liver approximate to muscle > blood > gill. The bioconcentration factor (BCF) and sediment/water partition coefficient (K-d) increased by 0.6-1.7 and 0.2-0.5 log units, respectively, for each additional CF2 moiety for PFCAs and PFSAs. PFAS concentrations in water showed no significant decreasing trend between 2009 and 2013 (p > 0.05), which indicates that Stockholm Arlanda Airport may be an important source for long-term contamination of the nearby environment with PFASs.
