Trace elements in the soil of some specific localities on Mt. Medvednica

Over most of the area the mountain massif of Medvednica is a nature park surrounded by settlements with more than one million inhabitants. It is a large forest complex covering about 20, 000 ha and containing several grassland enclaves intended for recreation, and grasslands and pastures used for cattle breeding purposes. The forest area is sporadically broken up by quarries, whereas old medieval mines are completely covered by forests. Research was conducted in four specific localities. The first locality refers to recreational areas - grasslands whose top parts are converted into skiing and sledging grounds in winter months. The second locality is grasslands used for grazing and producing hay in experimental cattle breeding programmes (cows, bulls and sheep). The third and the fourth localities are areas of medieval mines (lead-zinc ore). Soil analysis aimed at detecting trace elements was made for the topsoil layer 5 cm deep. The results of research reveal high values of Pb, Zn, Mn and Se in the “ Zrinski” mining site. Pb concentrations reach over 20, 000 mg/kg, those of Zn over 3, 000, of Mn more than 7, 000, of Cd 27, and of Se 1.2 mg/kg. High values of Pb (up to 500 mg/kg) and Mn (up to 2, 500 mg/kg) were found in the “ French” mine locality. Extremely high lead and zinc concentrations were to be expected since these are lead-zinc mines dominated by the minerals galenite (PbS) and sphalerite (ZnS) with considerable portions of silver, which was the reason for mining. High copper (230 mg/kg) and arsenic (100 mg/kg) values were also registered in this locality. The invariably increased values of arsenic in livestock pastures and mine localities are indicative ; in contrast, the skiing grass area manifests considerably lower values. Increased manganese values are the consequence of the geochemical composition of the bedrock.
