    Research Progress in Detection Methods of Per- and Polyfluoroalkyl Substances in Complex Matrices

    • 摘要: 全氟和多氟烷基物质(PFASs)是一类合成的持久性有机污染物,对环境和健康构成严重威胁。基于PFASs污染现状,聚焦复杂基质中PFASs残留检测技术,重点探讨了其在食品、纺织品、化妆品和中药等特殊领域的应用情况。通过比较国内外管控策略和检测标准,强调统一标准的重要性。还系统阐述了在PFASs检测中的固相微萃取、离子液体分散液液微萃取、基于纳米材料和新型材料等前处理技术,以及喷雾质谱法、基质辅助激光解吸质谱法、实时直接分析质谱法、原位分析、非靶向分析技术及机器学习等检测技术的研究进展,为满足监管需求,未来PFAS检测技术将更注重绿色环保、灵敏度、特异性、便携性和智能性(引用文献61篇)。

       

      Abstract: Per- and polyfluoroalkyl substances (PFASs) are a class of synthetic persistent organic pollutants that pose a serious threat to the environment and health. Based on the current situation of PFAS pollution, the detection technology of PFAS residues in complex matrices was focused, and its application in special fields including food, textiles, cosmetics, and traditional Chinese medicine was extensively discussed. The importance of unified standards was emphasized by comparing domestic and international control strategies and detection standards. The research progress of pretreatment technologies (solid phase microextraction, ionic liquid dispersion liquid-liquid microextraction, and nanomaterial and new material-based pretreatment technologies) and detection technologies (spray mass spectrometry, matrix assisted laser desorption mass spectrometry, direct analysis in real time-mass spectrometry, in-situ analysis, non-targeted analysis technology, and machine learning) in PFASs detection was also systematically described. The future PFAS detection technology will pay more attention to green environment, sensitivity, specificity, portability, and intelligence to meet regulatory requirements (61 ref. cited).
