Sažetak
The paper deals with multi-elemental analysis of the topsoil (0−10 cm) samples taken on the Medvednica Mountain, which is situated near Zagreb (the capital of Croatia) and some of its parts are ordinarily visited by the citizens and other hikers. During the past years, Medvednica Mt. has attracted the attention of several researchers from various scientific branches, e.g. geologists, biologists, silviculture scientists, etc. The list of the elements that were determined in this research consists of 25 selected metal(loid)s and (Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sr, Ti, Tl, V, and Zn) as well as C(org). The soil samples, which were tested in this study, were grouped according to their acidity. The samples were digested by aqua regia employing microwave digestion system. The selected metal(loid)s then were quantified employing ICP-OES technique. Organic carbon was determined by dry ashing method. Measurement quality control was carried out by multi-elemental analysis of the certified reference material for soil GBW07425. The results of the tested soil samples show that the mass fractions of most of the tested elements lie in their usual ranges, but in the samples that were collected in the areas which are anthropogenically influenced the concentrations of some of the elements (e.g. Cr, Ni, Pb, Zn) were elevated.
