Sažetak
The Karašica-Vučica River catchment area is located in eastern Croatia in the Pannonian Plain, and extends from Papuk and Krndija mountains in the south to Drava River in the north, and from the Municipality of Petrijevci in the east to the town of Slatina and the Municipality of Voćin in the west. It is located in the territory of Osijek-Baranja and Virovitica-Podravina Counties, which is a fertile agricultural and forested land with a total area of 2, 352.63 km2 (1, 419.87 km2 of which is agricultural land). The aim of this study was to collect and analyse data on concentration of heavy metals: copper, zinc, cadmium, chromium, nickel, lead, mercury, arsenic, manganese and iron, in Karašica-Vučica River surface waters. Samples were taken in the period 2010–2015 and cover several locations: Karašica Črnkovci, Karašica downstream from Valpovo, Vučica Marijančaci, Vučica Petrijevci and Vučica Beničanci. Mean annual value of heavy metals concentration was within legally defined boundaries, except in the year 2011 at location Črnkovci, where concentration of arsenic in surface water was elevated and amounted to 12.134 µg/L. Analysis of collected data regarding surface water of Karašica River points out to a slight increase in value of concentration of analysed metals, which are still within legally defined boundaries. One observed exception was concentration of arsenic, which by the year 2015 decreased to the value of 8.26 µg/L. Analysis of data regarding concentration of heavy metals in Vučica River surface water points out to a decrease in value, with highest observed concentrations measured at locations Beničanci and Marjančaci, and lowest at location Petrijevci. The exception was concentration of arsenic for which in 2012 higher value was measured at location Petrijevci (7.9 µg/L, in compare to 3.5 µg/L, measured at location Marjančaci, and 3.6 µg/L measured at location Beničanci).
