Abstract:Predstavljeni so rezultati geokemičnih preiskav v okolici površinskih kopov Kopriva (nahajališče naravnega kamna-apnenec) in Lipovški vrh (nahajališče apnenca za industrijske namene). Izvedli smo jih v okviru evropskega projekta LIFE IP RESTART. V sklopu omenjenega projekta se na degradiranih površinah omenjenih kopov, z namenom njihove revitalizacije, predvideva vzpostavitev testnih območij vgradnje sekundarnih materialov (mešanice recikliranih materialov in mineralnih surovin). Glavni cilj te študije je opredeliti izhodiščno stanje geokemične porazdelitve elementov v okoljskih materialih (kamninah, tleh, potočnih sedimentih in površinskih vodah) pred vzpostavitvijo testnih območij. Določene vsebnosti elementov bodo podlaga za spremljanje morebitnih okoljskih vplivov vgrajenih sekundarnih materialov. Rezultati so pokazali, da v kamninah zaradi geološke sestave (pretežno apnenec) med elementi prevladuje vsebnost Ca. Glede na zakonodajne smernice za tla smo ugotovili preseganja vsebnosti Pb v enem vzorcu (izvor je lahko antropogen ali naraven) in Ni v dveh vzorcih (predvidoma naraven izvor) v Koprivi. Na območju Lipovškega vrha so v Suhem potoku v dolvodnem sedimentu vsebnosti za elemente Mg, Na, Sr, Ca, Mn in S višje kot v gorvodnem sedimentu. Višje vsebnosti pripisujemo povečanemu antropogenemu doprinosu karbonatnega materiala vzdolž potoka (izpiranje materiala iz bližnjega kamnoloma in cest). V površinski vodi Suhega potoka smo ugotovili višje vsebnosti elementov S, Sr, B, U in Zn, ki niso presegle zakonodajnih smernic.

Title:Geochemical distribution of elements in the environmental media from the surroundings of open pit areas
Abstract:The results of geochemical investigations - carried out within the framework of the European project LIFE IP RESTART - in the degraded areas of the Kopriva (deposit of natural stone-limestone) and Lipovški vrh (deposit of limestone for industrial purposes) open pits are presented. There test sites of the installation of secondary raw materials (a mixture of recycled materials and mineral raw materials) with the aim of revitalizing degraded surfaces are planned. The main goal of this study is to define the baseline geochemical distribution of elements in environmental materials (rocks, soil, stream sediment and surface water) for the purpose of monitoring the potential environmental impacts of installed secondary raw materials. In rocks Ca content predominates due to the geological setting (predominantly limestone) of the studied areas. According to the legislative guidelines for soil, exceedances have been found for Pb in one sample (origin can be natural or anthropogenic) and Ni in two samples (presumably natural origin) from the area of Kopriva. In the area of Lipovški vrh in the stream Suhi Potok, higher contents of Mg, Na, Sr, Ca, Mn and S occur in the downstream sediment compared to upstream sediment. It is assumed higher contents occur due to anthropogenic contribution of carbonate material along the stream (washing of materials from nearby open pit and road). In the surface water of Suhi Potok, higher concentrations of S, Sr, B, U and Zn were determined. However, the concentrations did not exceed the legislative guidelines.
