Health aspect of two commercial fish species from the Belgrade Danube sector

Abstract

In this study, the concentrations of seven metals were determined in two commercial fish species, roach and white bream caught at two different sites in the Belgrade part of the Danube. The measured metal concentrations were below the standard concentrations recommended EU and the Republic of Serbia regulations. The EDI index values are far below the reference doses, which means that the risk of eating the fish analysed is minimal. The results obtained show no clear influence of untreated wastewater on the concentration of metals in the muscle of fish, but continuous monitoring of these pollutants is still necessary.

U ovoj studiji utvrđene su koncentracije sedam metala kod dve komercijalne vrste riba, bodorke i krupatice ulovljenih na dve različite lokacije u beogradskom delu Dunava. Izmerene koncentracije metala bile su ispod standardnih koncentracija preporučenih propisima EU i Republike Srbije. Vrednosti indeksa procenjenog dnevnog unosa (EDI) su daleko ispod referentnih doza, što znači da je rizik od konzumiranja analizirane ribe minimalan. Iako dobijeni rezultati ne pokazuju jasan uticaj neprečišćenih otpadnih voda na koncentraciju metala u mišićima riba, kontinuirano praćenje ovih zagađivača se i dalje preporučuje.
