Abstract In this work, a reliable and affordable QuEChERS sampling method is developed for simultaneous detection and quantification of 13 perfluorinated compounds (PFCs) in aquatic products. Liquid chromatography/tandem mass spectrometry (LC-MS/MS) was used for rapid analysis and the analytes were extracted using styrene-divinylbenzene copolymer (PS-DVB). The performances of the sorbents were evaluated based upon parameters, such as recovery and matrix effect. Under optimized conditions, the limits of detection of 13 PFCs were found to be lying within the range of 0.001–0.070 μg kg−1. The application of aquatic sampling demonstrated that ultra-trace levels of PFCs were successfully detected and quantified within the range of 0.028–31.0 μg kg−1 in tilapia (Oreochromis niloticus), salmon (Oncorhynchus mykiss), mussels (Perna viridis) and clam (Ruditapes philippinarum). Compared with the solid phase extraction method, the application of PS-DVB beads as an adsorbent proved to be quicker and successful in the determination of PFCs in aquatic samples.

使用 QuEChERS 开发苯乙烯-二乙烯基苯共聚物珠，用于同时检测和定量水产样品中的 13 种全氟化合物

摘要 在这项工作中，开发了一种可靠且经济实惠的 QuEChERS 采样方法，用于同时检测和定量水产品中的 13 种全氟化合物 (PFC)。液相色谱/串联质谱 (LC-MS/MS) 用于快速分析，并使用苯乙烯-二乙烯基苯共聚物 (PS-DVB) 提取分析物。吸附剂的性能根据回收率和基质效应等参数进行评估。在优化条件下，发现 13 种 PFC 的检测限在 0.001–0.070 μg kg-1 范围内。水生采样的应用表明，在罗非鱼 (Oreochromis niloticus)、鲑鱼 (Oncorhynchus mykiss)、贻贝 (Perna viridis) 和蛤蜊 (Ruditapes philippinarum)。与固相萃取方法相比，使用 PS-DVB 珠作为吸附剂被证明在测定水生样品中的 PFCs 方面更快、更成功。
