Abstract
Following the increasing attention on perfluorinated compounds, the European Union issued in 2010 a Commission Reccomendation on the monitoring of these contaminants in food. In this document it’s required to focus not only on the most commonly considered perfluorinated compounds, namely perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), but also on precursors forms including perfluorooctane sulfonamidoethanols (FOSEs) and fluorotelomer alcohols (FTOHs). In this general context, the objective of the present work was to develop an efficient analytical strategy for isolating (extract and purify) FOSEs and FTOHs from fish samples (notably 6:2 FTOH, 8:2 FTOH and 10:2 FTOH), and then identifying and quantifying these analytes by gas chromatography coupled to tandem mass spectrometry (GC-MS/MS).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
