Abstract

High-resolution gas chromatography—mass spectrometry of polychlorinated biphenyl congeners in biological samples A study is peroformed on polychlorinated biphenyl (PCB) congener residues in samples of human blood and milk as well as in falcon and pigeon eggs. Most of the PCB congeners found in these biological samples were quantified by high-resolution gas chromatography (HRGC). A PCB technical mixture —namely, DP6 (Phenochlor)— was used for the calibration as its composition was previously determined by HRGC—mass spectrometry. The usefulness of such a congener analysis is outlined. It is the firs time to be the best of our knowledge that a Phenochlor is used for standardization.
