    Abstract:
    Qualitative and quantitative composition of di- to octa-CBs have been determined in the Polish PCB mixture Chlorofen after HRGC-LRMS and 2D-HPLC and HRGC-HRMS separation, identification and quantification. 103 peaks representing up to 121 congeners from di-to octa-CB were quantified. Of the highly toxic planar PCBs only PCB IUPAC no. 77 was found at 10 microg/g concentration, while nos. 81, 126 and 169 were absent. Of the di- to octa-CBs a dominating congeners quantified in Chlorofen were nos.: 196/201 (19.7%), 194 (16.6%), 180 (12%),198 (9.5%), U7CB (8.6%) and 153 (5.3%).
