| Abstract: | The analysis of individual PCB components in river sediments with glass capillary gas chromatography was studied. For Aroclor 1242 a mean recovery of over 85 % was established. Decachlorobiphenyl contents obtained by perchlorination appear to be 1.1 to 3.7 times higher than total-PCB contents estimated with capillary GC. Besides reliable contents of individual PCBs the capillary method provides information about the composition of the PCB contamination in sediments and may be of use in the identification of PCB sources. |
