Distribution and behavior of selected elements in the Veliki Potok/Črnomerec Creek, Medvednica Mts., Croatia

The Veliki Potok/Črnomerec creek, Medvednica Mts., originates near the historical Pb-Zn-Ag mining site. The upper course of the creek flows through the Nature Park Medvednica presenting uninhabited and preserved nature area. The lower course flows through the city of Zagreb presenting urbanized area. Chemical characteristics of the stream water and sediment from the creek were investigated to examine the effects of historical mining activity and urbanization on the quality of water. Temperature, pH, redox potential, dissolved oxygen and conductivity of stream water were measured in situ. Concentrations of nitrates, ammonia, sulphates, phosphates and chlorides were determined in a laboratory. Concentration of heavy metals in stream water, as well as exchangeable metals content in stream sediments were estimated by atomic absorption spectrometry. According to obtained geochemical parameters, the Veliki Potok creek was divided into two principal segments. The upper course is characterized by moderate pH, high redox potential, low nitrate, ammonia, phosphate and sulfate concentration, as well as with low content of all analyzed metals with exception of manganese. The lower course shows high pH value, low redox potential, increased conductivity, increased content of nitrogen and phosphorous species and increased concentration of mercury and copper. The stream sediments from the lower course are characterized by high content of exchangeable metals, especially lead, zinc and copper.
