dc.description.abstractThe distribution and contents of organochlorine pesticides (OCPs) and congeners of polychlorinated biphenyls (PCBs) were analyzed in Bream (Blicca bjoerkna) and Barbel (Barbus barbus) from the Danube River, near Batajnica. 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, p,p'-Dichlorodiphenyldichloroethylene (p,p'-DDE), α-Chlordane, Dieldrin, Endrin, p,p'-Dichlorodiphenyldichloroethane (p,p'-DDD), p,p'-Dichlorodiphenyltri-chloroethane (p,p'-DDT)) and 7 PCB congeners (IUPAC numbers 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 by applying standard SRPS ISO methods. The statistically significant difference (p lt 0.05) was found between the OCPs content in Bream and Barbel, as well as between PCBs content in the analyzed fish filets. Among all analyzed pesticides, both fish contained the highest amounts of ΣDDT (expressed as sum of p,p'-DDT + p,p'-DDE + p,p'-DDD), (13.8 ng/g fish - Bream, 2.6 ng/g fish - Barbel). The sum of PCB congeners in Bream filets (40.8 ng/g fish) was significantly higher than in Barbel filets (7.2 ng/g fish). Results of Student's t-test (p = 0.05) showed the differences in the content of lipids, moisture, ash and calculated energy value between the analyzed fish filets. Four times higher fat content in Bream (4.25%) than in Barbel (1.07%) is one of the main reasons for higher content of OCPs and PCBs in Bream compared to Barbel, which were taken from the same location (The Danube River, Batajnica).en
dc.description.abstractU ovom radu prikazana je distribucija i sadržaj organohlornih pesticida (organochlorine pesticides, OCP) i polihlorovanih bifenila (polychlorinated biphenyls, PCB) u ribama krupatici (Blicca bjoerkna) i mreni (Barbus barbus) iz Dunava u blizini Batajnice. Ispitano je 16 organohlornih pesticida i 7 kongenera polihlorovanih bifenila. Anlizirana su sledeća jedinjenja: α-heksahlorocikloheksan (α-HCH), β-heksahlorocikloheksan (β-HCH), heksahlorobenzen (HCB), γ-heksahlorocikloheksan (γ-HCH), δ-heksahlorocikloheksan (δ-HCH), heptahlor, aldrin, cis-heptahloroepoksid (cis-HCE), trans-heptahloroepoksid (trans-HCE), γ-hlordan, α-hlordan, p,p'-dihlorodifenildihloroetilen (p,p'-DDE), dieldrin, endrin, p,p'-dihlorodifenildihloroetan (p,p'-DDD) i p,p'- dihlorodifeniltrihloroetan (p,p'-DDT) i PCB kongeneri označeni IUPAC brojevima 28, 52, 101, 138, 153, 180 i 118. Kvalitativna i kvanitativna ispitivanja ovih jedinjenja rađena su GC-ECD metodom. Sadržaj proteina, lipida, vlage i pepela u filetima riba određen je korišćenjem standardnih SRPS ISO metoda. Utvrđena je statistički značajna razlika (p lt 0,05) između sadržaja organohlornih pesticida u krupatici i mreni, kao i između sadržaja polihlorovanih bifenila u ispitanim ribama. Najveći sadržaj među ispitivanim organohlornim pesticidima, u obe vrste ribe utvrđen je za ΣDDT (pp'-DDT + pp'-DDE + pp'-DDD), (13,8 ng/g ribe - krupatica, 2,6 ng/g ribe - mrena). Ukupan sadržaj PCB jedinjenja u filetima krupatice (40,8 ng/g ribe) bio je značajno veći nego u filetima mrene (7,2 ng/g ribe). Na osnovu rezultata Studentovog t-testa (p = 0,05) utvrđeno je da postoji statistički značajna razlika u sadržaju masti, vlage, pepela i izračunate energetske vrednosti između fileta ispitanih riba. Četiri puta veći sadržaj masti u filetima krupatice (4,25%) u odnosu na filete mrene (1,07%) jedan je od glavih razloga većeg sadržaja organohlornih pesticida i polihlorovanih bifenila u krupatici nego u mreni, koje su uzete sa istog lokaliteta (Dunav, Batajnica).sr
