Wplyw zawartosci dioksynopodobnych kongenerow PCB w miesie ryb pochodzacych z Miedzyodrza na stopien zagrozenia toksykologicznego konsumentow

The aim of this study was the toxicological risk assessment for consumers on the basis of toxic equivalents (TEQs) from fish netted from Miêdzyodrze waters. The quantitative analysis of dioxin-like compounds (non- and mono-orto PCBs) were conducted using the capillary gas chromatography method (GC MSD HP 6890/5973). Toxic equivalents values were dependent of the most toxic congeners concentration, e.g. PCB 126 and PCB 169. Mean TEQ ranged from 0.03 ± 0.02 ng-TEQ/kg w.w. to 0.09 ± 0.01 ng-TEQ/kg w.w. The highest equivalents were received for ide’s meat and the lowest - for roach’s meat. Consideration of the mean consumption of fish in Poland and the highest TEQs of examined fish ascertained that their meat is safe for consumers from the hygienic and toxicological perspective.
