Abstract:

The purpose of this study was the detection of risk metal(loid)s such as As, Cd, Cu, Ni, Pb, Zn and the assessment of contamination level in the surveyed area of Staré Ransko deposit. Considering its rich mining history, Staré Ransko may represent potential hazard for its inhabitants. Therefore, we investigated these risk metals and the uptake by Norway spruce using sampling bark. Each sample was always taken from trees within the same species, of approximately the same age and from various distances from the deposit (i.e. contamination source). Three representative bark samples were collected, 1) close to the old mine, 2) in a waterbody area known as “mineralization Jezírka”, and 3) a control sample outside the studied area (i.e. off-site control sample). We found traces of many risk metal(loid)s differed due to their soil background, location and vegetation cover. The highest concentrations of metal(loid)s contamination was detected at the waterbody location (also known as “mineralization Jezírka”) and the least risk metal(loid) contamination was confirmed for the off-site (control) sample. Our results showed that the old mines can be a source of contamination of the studied area and potential mobility of several risk elements, depending on the site characteristics and its distance from ore deposit.
