Sažetak
The Ilova River is a lowland river situated in the central part of Croatia. In its lower course it is influenced by wastewaters of petrochemical industry, as well as by the municipal wastewaters. The aim of this study was to establish if the evident input of different wastewaters into the Ilova River has impacted the river water quality regarding the levels of dissolved metals in the surface water and the metals consequently accumulated in the gills of Prussian carp (Carassius gibelio), as tissue responsible for the waterborne metal uptake. Although Prussian carp represents an invasive species in the Ilova River, it is very abundant in its water and thus was considered as a suitable and representative bioindicator for this study. Fish were caught at two locations (the Ilova village as a reference site, and the Trebež village as a contaminated site) in two sampling campaigns (October 2017 and May 2018). Dissolved metal concentrations in the filtered and acidified samples of the river water, and total metal concentrations in the samples of acid digested gill tissues were measured by high resolution inductively coupled plasma mass spectrometry. The obtained results indicated that several elements (Na, Li, Rb, Cd, Cs, Tl, U, Al, and Ti), mainly nonessential and rather toxic, were present in significantly higher concentrations in the vicinity of the Trebež village both in the fish gills and in the river water in both seasons, thus pointing to observable impact of known contamination sources on the aquatic life in the Ilova River.
