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 (FTSA) 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±80μg absolute and was distributed as follows: Gonad>liver≈muscle>blood>gill. The bioconcentration factor (BCF) and sediment/water partition coefficient (Kd) 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.
由于使用了含有全氟和多氟烷基物质（PFAS）的水基消防泡沫（AFFF），消防训练设施可能成为周边环境中 PFAS 的潜在来源。在瑞典斯德哥尔摩阿兰达机场的一个消防训练设施附近，对全氟烷基羧酸（PFCAs）、全氟烷基磺酸盐（PFAS）、全氟辛烷磺酰胺（PFOSA）和 6:2 氟代烷烃磺酸盐（FTSA）进行了多介质分布研究。欧洲鲈鱼（Perca fluviatilis）体内的 PFAS 总负荷为 334±80μg 绝对，分布如下：性腺>肝脏≈肌肉>血液>鳃。对于 PFCAs 和 PFAS，每个额外的 CF2 部分，生物浓缩因子（BCF）和沉积物/水分配系数（Kd）分别增加了 0.6-1.7 和 0.2-0.5 个对数单位。2009 年至 2013 年间，水中的 PFAS 浓度没有明显的下降趋势（p>0.05），这表明斯德哥尔摩阿兰达机场可能是附近环境中 PFAS 长期污染的重要来源。
