Discharges of wastewater, enriched with inorganic and organic chemicals, may induce
pollution of the aquatic environment and thus affect biological communities. The main
problem considering pollution of the Danube River in Belgrade represents the
discharges of wastewaters without any previous treatment. This study aims to assess
the distribution of pollutants (metals and trace elements, PCBs and pesticides) in the
tissues of two commercial fish species (common bream and pike-perch) belonging to
the different trophic levels. The metal and trace element concentrations were assessed
by inductively coupled plasma mass spectrometry (ICP-MS) while organochlorine
pesticides (PCBs and pesticides) were assessed by gas chromatography with electron
capture detectors (GC-ECD). Detected As, Cd, Pb and Hg concentrations in the fish
muscle were below the maximum allowed concentrations (MAC) established by both
the EU and the Republic of Serbia. Gills significantly differ in the concentrations of
the most assessed metals and trace elements while liver differs among species in
concentrations of As, Cd, Hg and Zn. Detected ndl PCB and pesticides concentrations
in both analyzed species were below MAC established by both the EU and the
Republic of Serbia. Statistical analysis revealed no significant differences in ndl PCB
and pesticides concentrations among analyzed species. In this study it was shown that
high position in the food chain doesn’t indicate higher tissue contamination, even
though arsenic, cadmium, mercury and iron were in higher concentrations in liver and
gills of pike-perch.
