abstract

  • In recent years, perfluorinated organic compounds have appeared as a new class of global pollutants, being widely distributed in many environmental matrices, including those in remote locations. Besides being an industrially important group of compounds, they are regarded as persistent, bioaccumulative, and toxic chemicals. The aim of this study is to determine the levels of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in drinking water, river water and selected fish species from the Rhine river area. The compounds were isolated by liquid-liquid extraction from fish and solid-phase extraction from water samples. Identification and quantification of the target analytes were achieved by high performance liquid chromatography - negative-ion electrospray ionization tandem mass spectrometry. The method gave recoveries ranging from 72 to 111 %. Perfluorinated compounds were detected in most river and drinking water samples at concentrations ranging between 0.4 - 5.2 ng L -1 for PFOA and 0.4 - 7.5 ng L -1 for PFOS. PFOS levels in trout and roach fish were 3.1 ng g -1 and 2.1 ng g -1, respectively, in liver samples. © by PSP.
