| Abstract: | A method for the analysis of polychlorinated naphthalenes (PCN) has been developed. It is based on a simple clean-up procedure using activated carbon and a mass fragmentographic analysis using the negative ions formed during chemical ionization (NCI). Unlike the technical PCN products we have analyzed, a few isomerides containing four to six chlorine atoms dominate the PCN pattern in the environmental samples. The levels found in samples of biota from fresh water and marine environments in Sweden were between 3 and 62 ng PCN per gram lipid. |
