20.500.12556/DiRROS-23415 Geokemični atlas Maribora Geochemical atlas of Maribor Poznavanje prostorske porazdelitve vsebnosti kemičnih elementov v tleh je bistveno za zagotavljanje varnega in zdravega bivalnega okolja ter pomembno za prostorsko načrtovanje, posege v prostor in spremljanje dolgoročnih antropogenih vplivov na okolje. Zaradi velikega števila prebivalcev je to še posebej pomembno v urbanih okoljih. V monografiji podajamo rezultate raziskav vsebnosti kemičnih elementov, pH vrednosti in vsebnosti celotnega ter organskega ogljika v tleh v Mariboru in prikaze njihovih prostorskih porazdelitev z geokemičnimi kartami. Vzorčili smo zgornjih 10 cm tal po celotnem Mariboru v mreži 500 × 500 m. Po razklopu z zlatotopko smo z ICP-MS analizirali vsebnosti 65 elementov. Rezultati kažejo, da tla na območju Maribora niso močno obremenjena s potencialno strupenimi elementi, odkrili smo le manjša območja in nekatere izolirane lokacije z visokimi vsebnostmi bakra (Cu), svinca (Pb) in cinka (Zn), predvsem znotraj industrijskih območij ter starega mestnega jedra. Njihove mediane, ki so nekoliko nad slovenskimi, velika variabilnost v vsebnostih in prostorska porazdelitev kažejo na vsaj deloma antropogen izvor. Deloma antropogen izvor lahko pripišemo tudi kadmiju (Cd), antimonu (Sb), kositru (Sn), živemu srebru (Hg) in srebru (Ag). Nekateri preostali elementi, kot so aluminij (Al), kobalt (Co), krom (Cr), železo (Fe) in vanadij (V) jasno odražajo prevladujoč vpliv geološke podlage. S predstavljeno raziskavo smo želeli opredeliti trenutno geokemično stanje tal v Mariboru, približati rezultate splošni javnosti in omogočiti dolgoročno spremljanje stanja tal ter okolja na splošno. Understanding the spatial distribution of levels of chemical elements in soil is crucial for ensuring a safe and healthy living environment. It also plays an important role in spatial planning, land use management, and monitoring long-term anthropogenic impacts on the environment. This is particularly relevant in urban areas due to their high population density. This study presents the results of research on the levels of chemical elements, pH values, and total and organic carbon contents in the soil of Maribor, along with spatial distribution maps. Soil samples were collected from the upper 10 cm across the entire city using a 500 × 500 m grid. After digestion with aqua regia, the levels of 65 elements were determined using ICP-MS. The results indicate that the topsoil in Maribor is not heavily contaminated with potentially toxic elements. However, we identified several smaller areas and a few localized sites with elevated levels of copper (Cu), lead (Pb), and zinc (Zn), primarily within industrial zones and the historic city centre. Their slightly elevated medians compared to Slovenian medians, along with high variability of levels and spatial distribution, suggest at least a partially anthropogenic origin. A partially anthropogenic origin can also be attributed to cadmium (Cd), antimony (Sb), tin (Sn), mercury (Hg), and silver (Ag). In contrast, some elements, for example aluminium (Al), cobalt (Co), chromium (Cr), iron (Fe), and vanadium (V) clearly ref lect the predominant inf luence of the geological setting. With this study, we aimed to define the current geochemical state of the soil in Maribor, make the findings more accessible to the general public, and enable long-term monitoring of soil and environmental conditions. soil chemical elements potentially toxic elements geochemical mapping urban geochemistry true false true Geološki zavod Slovenije, = Geological Survey of Slovenia Slovenski jezik Angleški jezik Neznano 2025-08-27 03:43:23 2025-08-28 11:54:02 2025-12-24 09:36:10 0000-00-00 00:00:00 2025 0 Ljubljana 2025 Ljubljana 88 str. no. 1 vol. 68 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-07-25 550.4(497.4Maribor)(084.4)(0.034.2) 978-961-6498-84-5 10.5474/geologija.2025.002 242776579 Geologija_68_1_2025.pdf Geologija_68_1_2025.pdf 1 769DCECE9DEDAB68180F917BF5616E8C d0dd8679de61eb0d498655774237c8117f8153491c044de7ad09d7205d758901 708dfd09-83f5-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34639 Geološki zavod Slovenije Geologija 0 0 0
