o:3765 ASSESSMENT OF THE CONTENT OF MACRO, MICRO AND POTENTIALLY TOXIC ELEMENTS IN THE SOIL OF THE SERBIAN MOUNTAINS BY MULTIVARIATE ANALYSIS PROCENA SADRŽAJA MAKRO, MIKRO I TOKSIČNIH ELEMENATA U ZEMLJIŠTU SRPSKIH PLANINA MULTIVARIJANTNOM ANALIZOM en The goal of this investigation was to assess the presence, content and limit concentrations of macro elements of plant nutrituion, trace elements, and potentially toxic elements in the soil. The research was carried out in Kopaonik, Crni Vrh and Mokra Gora during the period 2020-2022 on the different depths. Samples were prepared by microwave digestion with mixture of mineral acids. Concentration of extractedelements were measured by Inductively Coupled Plasma Optical Emission spectroscopy (ICP-OES). The method of sample preparation is very important for the successful determination of elements because it is a very complex matrixChemometric approach was applied to explain the distribution of elements and potentially toxic elements in the soil by location and sampling depth. Principal Component Analysis and Cluster Analysis have proven to be excellent tools for reducing the number of measurements and for grouping data by parameters and by sampling location. Research has shown that there was no major soil contamination with toxic metals in the selected areas. soil, microwave digestion, trace metals, ICP-OES, PCA, HCA 1552099 10.5937/SustFor2388001B 1552101 1821-1046 2024-01-16T09:19:22.859Z 44 yes 46 Jelena Božović 0000-0002-9304-0970 46 Snežana STAJIĆ 0000-0001-9023-3542 46 Ilija ĐORĐEVIĆ 0000-0001-9499-3565 46 Bojan KONATAR 0009-0006-9023-4397 46 Goran ČEŠLJAR 0000-0003-0438-1050 46 Dragana ŽIVOJINOVIĆ application/pdf 354384 https://unilib.phaidrabg.rs/o:3765 no yes 16 70 1552253 Sustainable Forestry: Collection 87-88 1 8 Институт за шумарство 2023
