The aim of the research was to determine concentrations of non-ortho (PCB nr 77, PCB nr 126, PCB nr 169) and mono-ortho (PCB nr 114, PCB nr 156, PCB nr 157) PCB congeners in selected food products from marine invertebrates. The data were used to asses toxicological risk of the products for consumers by determination of toxic equivalents TEQs. PCB congeners were found in 10 types of the tinned marine invertebrates witch were purchased in 2004 from retail network in Szczecin. The capillary gas chromatography in a GC MSD apparatus (6890/5973) was used. Residues of analysed PCB congeners were detected in all examined products. Only PCB 114 was not found in „Octopuses in Plant Oil” and „Coldwater Shrimps in Marinade”. Of non-ortho PCB congeners, the highest concentration of PCB 77 was found in „Crabs in Natural Juices” (0,264 μg·kg^-1 w.m.). Of mono-ortho PCBs, the highest concentration of PCB 114 was found in „Smoked Oysters in Oil” (0,793 μg·kg^-1 w.m.). TEQs ranged from 0,0004 μg·kg^-1 w.m. in „Marinated Clams” to 0,0065 μg·kg^-1 w.m. in „ Octopuses in Plant Oil”. Marine invertebrates are subjected to culinary treatment preceding consumption, so they are characterized by low concentrations of toxic PCB congeners. Considering toxicological aspects the food products from marine invertebrates are safe for consumers.
