The distribution and concentrations of organochlorine pesticides (OCPs) and congeners of polychlorinated biphenyls (PCBs) were analyzed in two wild fish species (European perch, Perca fluviatilis, and Blue bream, Abramis ballerus) from the Danube River, Iron Gates region, Serbia. The analysed compounds were 16 OCPs (α-Hexachlorocyclohexane (α-HCH), β- Hexachlorocyclohexane (β-HCH), Hexachlorobenzene (HCB), γ-Hexachlorocyclohexane (γ-HCH), δ-Hexachlorocyclohexane (δ-HCH), Heptachlor, Aldrin, cis-Heptachloroepoxide (cis-HCE), trans- Heptachloroepoxide (trans-HCE), γ-Chlordane, α- Chlordane, p,p'-Dichlorodiphenyldichloroethylene (DDE), Dieldrin, Endrin, p,p'-Dichlorodiphenyldichloroethane (DDD), p,p'-Dichlorodiphenyltrichloroethane (DDT)) and 7 PCB congeners (28, 52, 101, 138, 153, 180, 118). Determination and quantification of OCPs and PCBs were performed by a GC-ECD method. The proximate composition of fish fillets was determined, as well. It was found that Blue bream contain a higher number and significantly higher content (p<0.005) of the examined pollutants, found in both fish species, than European perch. Results of Student’s t-test showed differences (at significance level 95%) between all items of proximate composition and energy values of analyzed fish fillets.
