全氟烷基酸 (PFAA) 在环境中无处不在。它们很容易在生物体中积累，并在近几十年来引起了公众的关注。羽毛样品已成功用作多种污染物的无损指示剂。然而，仍然缺乏确定羽毛中 PFAA 的复杂分析方法。在本研究中，对羽毛中 13 种 PFAA 的分析优化了一系列条件，例如使用固相萃取柱类型和萃取/消解方法。根据加标回收率，选择弱阴离子交换柱，并选择甲醇作为萃取溶剂。本研究建立了优化的前处理程序结合高效液相色谱-电喷雾电离-串联质谱（HPLC-ESI-MS/MS）方法来测定羽毛中的PFAA。 PFAA 的回收率和方法检测限分别为 71 至 120% 和 0.16 至 0.54 ng/g。最后，对青藏高原纳木错盆地的四个鹰羽毛样品中的 13 种 PFAA 进行了分析，结果表明，PFOS 是鹰羽毛中的主要 PFAA，平均值为 4.67 ng/g，其次是短链 PFAA、PFBS 和 PFBA，平均值分别为 1.91 ng/g 和 1.39 ng/g。这些结果部分反映了纳木错盆地PFAA污染现状，特别是该地区短链PFAA的存在。
Perfluoroalkyl acids (PFAAs) are ubiquitous in the environment. They are prone to accumulate in organisms and have raised public attention in recent decades. Feather samples have been successfully applied as nondestructive indicators for several contaminants. However, a sophisticated analytical method for determining PFAAs in feathers is still lacking. In the present study, a series of conditions, such as the use of the solid-phase extraction cartridge type and extraction/digestion methods, were optimized for the analysis of 13 PFAAs in feathers. According to the spiked recoveries, a weak-anion exchange cartridge was chosen and the methanol was selected as the extraction solvent. In the present study, an optimized pretreatment procedure combined with high-performance liquid chromatography–electrospray ionization–tandem mass spectrometric (HPLC–ESI–MS/MS) method was established for the determination of PFAAs in feathers. The recoveries and method detection limits of the PFAAs ranged from 71 to 120% and 0.16 to 0.54 ng/g, respectively. Finally, 13 PFAAs in four accipiter feather samples from Nam Co Basin, Tibetan Plateau, were analyzed, indicating that PFOS was the predominant PFAA in accipiter feathers, with an average of 4.67 ng/g, followed by the short-chain PFAAs, PFBS and PFBA, with averages of 1.91 and 1.39 ng/g, respectively. These results partly indicated the current situation of PFAA pollution in the Nam Co Basin, especially the existence of short-chain PFAAs in this region.
