In this work, the distribution of polycyclic aromatic hydrocarbons (PAHs) was examined in the soil from the Bor region, sampled from the rooting zones of poison ivy. The samples were taken from different locations in the Bor town and its surroundings and analyzed using gas chromatographic-mass spectrometric method, and hierarchical cluster analysis with the average linkage between groups as an appropriate statistical method. The obtained results soundly illustrated the distribution of individual PAHs in soil and simultaneously, they indicated probable PAH sources, i.e., anthropogenic or natural. In accordance with the obtained hierarchical dendrogram, it can be supposed that only benzo(a)pyrene had a natural origin (from different processes in the soil), whereas all other PAHs had anthropogenic, i.e. atmospheric origin. The grouping of the latest compounds showed that they were kept in soil for different - longer or a shorter time.

The study aims to explore the environmental factors which activate accumulation abilities of Plantago lanceolata in the research area under strong anthropopressure resulting from the long-term pollution originating from copper mining-metallurgical activities in Southeastern Europe. Sampling was performed at the most endangered sites regarding its proximity to the major and/or secondary pollution sources, as well at the control site. The content of toxic elements (Al, Cu, Fe, Mn, Ni, Pb and Zn) was determined in the roots, leaves, stalks and flowers of P. lanceolata. The anthropogenic origin of environmental contamination was denoted through the high concentrations of Cu, Pb and Zn in the leaves of P. lanceolata, reaching toxic levels, combined with the enrichment of plant parts (Enrichment factor >2), especially with Cu (as well as with Al, Fe, Ni and Zn) in samples from the immediate proximity to the copper smelter or at the prevailing wind directions. Biomonitoring potential, assessed through the correlations between toxic element content, as well as the values of Enrichment factor, was indicated for roots (in the case of Cu), all the aboveground plant parts (Fe) and stalks (Zn). The results have shown that the contents of toxic elements in plant parts as well as phytoremediation of P. lanceolata were dependent on soil element content, soil physico-chemical properties and soil enzyme activities, which were regarded as the main environmental drivers affecting phytoremediation ability. The analysis of biological factors (bioconcentration, translocation and bioaccumulation factor) indicated exclusion strategy and possible usage of P. lanceolata in phytostabilization of Zn. The results indicated that the study area is 'environmental hotspot' with potential threat to human health due to the high levels of bioaccumulation of the investigated toxic elements in P. lanceolata parts.
Case study on metal(loid)s distribution in linden tree parts, in areas with hight environmental pollution
(University of Belgrade, Technical Faculty in Bor, 2025) Kalinović, Tanja; Radojević, Ana; Kalinović, Jelena; Jordanović, Jelena; Šerbula, Snežana
The investigation focuses on the distribution of Al, Fe, Cu, Zn, Pb, As, and Cd, in the roots, branches and leaves of linden tree, a very common plant species used in traditional medicine, sampled in the area affected by pollution from the mining-metallurgical facilities for copper production, and one unpolluted zone. Plant samples were collected and processed following the established scientific methods, while concentrations of metal(loid)s were determined using the ICP-AES. Distinct patterns in the metal(loid)s distribution in the linden parts were revealed, which varied depending on the environmental pollution levels, highlighting obvious differences between the polluted and unpolluted zones.
Comparative assessment of potentially toxic elements bioaccumulation and biomonitoring ability using rosehip, hazelnut, and black elder leaves
(Crnogorsko društvo za koroziju, zaštitu materijala i zaštitu životne sredine, 2025) Šerbula, Snežana; Kalinović, Tanja; Radojević, Ana; Kalinović, Jelena; Jordanovic, Jelena
This paper aims to evaluate and compare the environmental role of the rosehip, hazelnut and black elder, in areas with various anthropogenic sources of pollution. In addition to the essential elements for plants such as Ni, Zn, Cu and Fe, the leaves of the studied plant species contained certain amounts of toxic or non-essential elements such as Cd, As, Pb and Al. The concentrations of the analysed elements in the hazelnut and elder leaves from the urban-industrial (UI) and rural (R2) sampling sites stood out in the box plot analyses by the highest number of outlying (mild and extreme) data points. Cu and Pb were the elements with the highest values of the Enrichment factor (EF), in the leaves of the studied plant species, while enrichment was also noted for Zn, Fe, Al, As and Cd, depending on the sampling site and plant species. The highest EF values were calculated for the samples from the UI and R2 sampling sites. The rosehip, hazelnut and elder leaves have a good retention capacity for particulate matter originating from the air containing potentially toxic elements (PTEs), and thus represent green resources for monitoring and mitigation of environmental pollution.
Potential of using zinc processing tailings (ZPT’s) in the production of burnt clay bricks
(University of Belgrade, Technical faculty in Bor, 2025) Messai, Ali; Berrekbia Linda; Meramria, Ikram; Menendez-Aguado, Juan Maria; Fernandez-Perez, Begona; Nikolić, Vladimir; Trumić, Milan; Boustila, Amir
Zinc processing tailings (ZPTs) from the Kharzet Youcef processing complex (Setif- Algeria) are mainly stockpiled in tailings dumps without use, occupying a significant area with potentially influencing the environment and human health. Incorporating ZPTs in building materials manufacturing is an effective solution to meet the dual objectives of environmental protection and economic development. The study investigates the influence of integrating ZPTs to partially replace clays and firing temperature on the physic-mechanical properties of fired clay bricks (FCB). Microstructural, chemical, and mineralogical analyses of ZPT and clays were carried out by SEM-EDS, XRF and XRD, respectively. Seven mixtures were produced with various percentages of ZPTs added to clays (0%, 5%, 10%, 15%, 20%, 25% and 30%) and were fired to three different temperatures (950, 1000 and 1050 °C) at a ramp rate of 5 °C. Physic-mechanical tests were carried out on different brick specimens, and the results obtained showed the FCB incorporated with 30% of ZPTs produced the highest flexural strength of 6.24 MPa, compressive resistance of 29.78 MPa, bulk density of 1.37 g/cm3 and water absorption of 15.1% at 900 °C. Therefore, recycling ZPTs for FCB manufacturing is a feasible alternative waste disposal solution for sustainable development while reducing negative environmental impacts.
