食品中全氟化合物分析技术研究进展
全氟化合物(perfluorinated compounds, PFCs)是一类人工合成的脂肪烃类化合物, 自上个世纪50年代合成以来, 该类化合物以其优良的稳定性及表面活性作为加工助剂被应用于多种民用及工业领域, 如纺织品、灭火器和油漆等行业。近些年来越来越多的调查研究发现, 在空气、沉积物、饮用水、海水和食品中检测出全氟类化合物。膳食作为人体暴露PFCs的重要途径之一, 已受到了各国研究人员的重视。本文综述了食品中PFCs的检测技术的研究进展, 讨论了不同食品中PFCs的前处理及检测方法, 当前主要采用离子对液液萃取和液固萃取, WAX柱净化提取液, 液相色谱-质谱联用技术定量分析食品中的PFCs。由于食品中PFCs处于痕量水平, 对该类物质的检测方法中空白本底的控制尤为重要。另外, 全氟化合物存在的多种同分异构体之间的差异将是研究人员对其准确监测的困难之一。
Perfluorinated compounds (PFCs) are a group of manmade fluorinated aliphatic compounds. Due to their special stable and surfactant properties, PFCs have been applied for a wide range of industrial and civil use as processing acids since manufactured in 1960s. PFCs have been detected in a variety of matrices such as air, sediment, drinking water and seawater, and so on. Diet has attracted attention of researchers as an important pathway of human exposure to PFCs. In this paper, the recent advances of determination for PFCs in foodstuffs are reviewed. The methods of sample pre-treatment and detection of PFCs in different foodstuffs are discussed, and the main extraction methods of PFCs in foodstuffs are ion-pair liquid-liquid extraction and liquid-solid extraction, further purified by WAX column, and then, analysis of PFCs is mostly carried out by Liquid chromatograph-tandem mass spectrometer. Since the concentration of PFCs in foodstuffs is in trace levels, controlling the blank background is particularly important. In addition, the existing of differences between the various isomers of the PFCs is one of the difficulties of accurate monitoring for researchers.
