(083) Detection and Quantification of Perfluorochemicals in Environmental Samples.
Simcik, Matt*,1, Dorweiler, Kelly1, 1 University of Minnesota, Minneapolis, MN, USA
ABSTRACT- A chemical class of emerging concern in environmental chemistry is that of perfluorochemicals. These compounds are extremely persistent, and in the case of perfluorooctane sulfonate have been found in wildlife around the globe. While perfluorinated surfactants have been around for quite some time, only recently have analytical techniques been developed to adequately quantify these compounds in environmental samples. The instrumentation of choice to date has been liquid chromatography with triple quadrapole mass spectrometry (LC/MS/MS). These instruments are quite expensive, and so we have developed a method for perfluorochemical analysis using liquid chromatography with single quadrapole mass spectrometry (LC/MS). We will present our analysis technique and results from the analysis of surface water and fish from the Great Lakes region, with implications for sources and transport.
Key words: perfluorochemicals, pfos, surfactants, LC-MS
