摘要：

A gel permeation chromatographic method was developed for the isolation and determination of small amounts of polychlorinated naphthalenes (PCNs) present in polychlorinated biphenyl (PCB) products. The method was applied to nine commercial PCB products: Aroclor 1016, 1232, 1242, 1248, 1254 and 1260 and Clophen A30, A40 and A50. All products were found to contain total PCN concentrations between 1.8 and 870 mug/g. High concentrations of PCNs were detected in Clophen A30 and A40 whereas a low concentration was found in Clophen A50. The PCN congeners were dominated by compounds substituted with two to six chlorine atoms.
