| Research Abstract |
The aim of this study was to perform congener-specific determination of polychlorinated naphthalenes (PCN) using two-dimensional gas chromatography mass spectrometry (GCxGC/MS) for prediction of their environmental fate. As a result, 73 PCN isomers among all the 75 isomers could be separated with developed GCxGC/MS method. In addition, the accuracy of fingerprint and risk assessment was enhanced based on congener-specific data obtained by applying the developed method to several environmental samples. Moreover, this method was applicable to analysis of polybrominated naphthalenes (PBN). From the results in this study, comprehensive determinations of PCN/PBN could be performed, thereafter, it is expected that the scope of the method will be expanded to many related environmental contaminants including PCN/PBN.
