Abstract
The use of dechlorination and subsequent analysis by means of column liquid chromatography (LC) as a quantitative, or qualitative, method of analysis for polychlorinated biphenyls (PCBs) and terphenyls (PCTs) and hydroxylated PCBs has been evaluated. A relatively simple dechlorination procedure with LiAlH4 as reagent has been developed and applied to various types of PCB-containing environmental samples, analysis being carried out by adsorption LC in the system silica gel/hexane with UV detection. The results are compared with those obtained by means of the gas chromatographic pattern-comparison and perchlorination methods. Preliminary data are presented on the use of dechlorination for the analysis of PCTs in environmental samples. Besides, the utilization of dechlorination as an aid for structure elucidation in metabolic studies of PCBs is reported.Keywords
