全氟烷基酸（PFAA）作为生产副产品或其前体降解而排放到环境中。开发有效的识别和定量PFAAs在不同的环境介质中是重要的环境和人类健康风险评估。本研究采用人工提取和加速溶剂提取（ASE）两种方法对海水和海水沙蚕中9种全氟乙酸进行了提取测定。采用固相萃取法对海水样品中的全氟辛酸进行净化富集。采用高效液相色谱-串联质谱法分析样品中全氟辛酸的含量。海水样品中替代物（SUR）的回收率分别为52 - 72%（空白）、52 - 88%（1 ng）和56 - 79%（10 ng）。沙虫的手动提取导致SUR化合物的回收率为57%至93%。ASE提取得到较高的回收率的SUR化合物（62至92%）。海水和沙虫提取的分析方法可以确保高质量的PFAA数据的生产。
Perfluoroalkyls acids (PFAAs) have been emitted in the environment either as manufacturing by products or through degradation of its precursors. Development of efficient identification and quantification of PFAAs in different environmental media is important for environmental and human health risk assessments. In this study, different extraction methods were developed to determine nine (9) different PFAAs in seawater and seawater sandwormPerinereis wilsoni.P. wilsoniextracted using two methods: manual extraction and accelerated solvent extraction (ASE). Solid phase extraction method was used for the clean-up and preconcentration of PFAAs from the marine water samples. High-performace liquid chromatography–tandem mass spectrometry was used to analyze PFAAs concentrations in the samples. Percent recoveries of surrogate (SUR) in marine water samples were between 52 to 72% (blank), 52 to 88% (1 ng), and 56 to 79% (10 ng). Manual extraction of sandworm resulted in 57 to 93% recovery of SUR compounds. ASE extraction gave higher recoveries of SUR compounds (62 to 92%). The developed analytical methods for seawater and sandworm extraction can assure production of good quality PFAAs data.
