keywords: polychlorinated biphenyls, the tuna, toxic equivalence (TEQ)
abstract: . In present work the levels of total PCB and the most toxic non-ortho ( PCB 77, PCB 126, PCB 169) and mono-ortho (PCB 114, PCB 156, PCB 157) congeners contents in selected imported tinned tuna in own sauce were investigated. The quantitative and qualitative determination of these compounds was made using capillary gas chromatography method (GC MSD HP 6890/5973). In most of assortments the contents of congener PCB 169 was detected. Calculated toxic equivalences (TEQs) for investigated tins resulted from 10 to 200 pg-TEQ/kg w.w. The contents of total PCB was noted at the level of 1.4-11.4 g/kg w.w.
