✦ Synopsis

This article describes and critically evaluates a complete method for the quantitation of PCB in sediment samples. The extraction and clean-up procedure is described. Packed column and capillary column results are compared. Capillary column quantitation yields lower values for total PCB loading. Preferences for capillary column quantitation are discussed and explained. Capillary quantitation is based on the combination of an external Aroclor standard and an internal decachlorobiphenyl standard for normalizing data. In light of the recent report of synthesis of all 209 PCB congeners a suggestion is made to use these as absolute standards to establish a bank of primary standard Aroclors.
