AB  - The molecular and isotopic composition of biomarkers in initial bitumen isolated from immature (0.41% Rr) oil shale samples (Aleksinac deposit) and liquid products obtained by pyrolysis in open (OS) and closed (CS) systems are studied. The influence of pyrolysis type and variations of kerogen type on biomarkers composition and their isotopic signatures in liquid products is determined. The applicability of pyrolysis type, numerous biomarkers and carbon isotopic compositions (δ13C) of n-alkanes in liquid pyrolysates is established. Pyrolysis experiments were performed on two selected samples that showed high content of total organic carbon and hydrocarbon generation potential, but also certain variations in sources/depositional environment of organic matter (type I and mixed type I/II kerogen) within previous research of the oil shales sample set. The biomarker signatures were evaluated using gas chromatography-mass spectrometry (GC-MS) and δ13C of individual n-alkanes in bitumen and liquid pyrolysates. The molecular composition of liquid pyrolysates from the OS is very similar to those in initial bitumen, independently on kerogen type, confirming algal origin of organic matter (OM) deposited in lacustrine environment, even more apparently than results of initial bitumen. Therefore, OS can be useful for assessment of source and depositional environment of OM. Pyrolysis in the CS caused more intense thermal alterations, therefore the source fingerprints sometimes notably disappear. The liquid pyrolysates from the CS have the distributions of biomarkers similar to those in crude oils. The biomarker maturity parameters showed slightly higher values in the CS pyrolysate of mixed type I/II kerogen in relation to type I kerogen. δ13C of n-alkanes in liquid pyrolysates from the OS are isotopically lighter in comparison to bitumen, independently on kerogen type. Oppositely, in liquid pyrolysates from the CS, they become heavier than in bitumen, indicating the thermal influence on δ13C signatures, with more pronounced difference for type I kerogen.

AB  - Purpose The Great War Island (GWI) is a landform of exceptional features and a protected area located in the center of
Belgrade at the Sava and Danube River’s confuence. The position of GWI causes a large number of possible hydrocarbons inputs that infuence the quality of both river waters and sediments. The main objective of this research is to assess
the distribution and source of hydrocarbons in sediments deposited at the GWI depending on the river’s fow regimes and
depositional environment.
Material and methods Sediment samples were collected from 16 sites (11 sites along the GWI’s coast, 4 sites from the
inner of the Island, and 1 specifc wetland site). The grain size was determined using a standard wet sieving procedure. The
extractable organic matter (OM) was quantifed after Soxhlet extraction, and aliphatic and aromatic fractions were isolated
by column chromatography. n-Alkanes, diterpanes, terpanes, steranes, and 16 PAHs are analyzed by gas chromatographymass spectrometry.
Results and discussion Sand fraction predominates in coastal samples, and clay size fraction in the samples from the inner
island environment. The predominance of odd higher n-alkanes indicates the terrestrial origin of OM, while the distribution
of lower n-alkanes indicates a certain proportion of algae, bacteria, and/or high maturity of OM. The presence of oil-type
pollutants is confrmed by thermodynamically stable biomarker isomers and/or the presence of unresolved complex mixture
(UCM). Inner island samples are characterized by the largest amount of Corg (up 6%), indicating high bioproductivity and
good preservation of OM. Samples from wetland environment are distinguished by the domination of pimaranes and phyllocladanes among saturated hydrocarbons.
Conclusions This study revealed that sediments of the GWI mainly contain native OM with a certain anthropogenic input.
The native OM predominately comes from higher terrestrial plants (Salix alba, Populus nigra, Fraxinus viridis, Taxodium
distichum Rich.), followed by various types of grasses, macrophytes (Salvinia natans, Nymphaea alba), bacteria, algae, and
phytoplankton. Anthropogenic OM originates from petroleum, but also combustion products arrived by deposition from
the air and runof.

AB  - Biological markers (BMs) are organic compounds in oils in which a precursor is known, and during the transformation of organic matter these compounds undergo certain structural and stereochemical changes. Based on the established precursors of BMs, the origin of the examined oils can be estimated, and based on the intensity and the type of changes and also geological history. It includes defining the deposition medium, the degree of maturation, the length of the oil migration path, the degree of biodegradation. The most studied and applied BMs are normal alkanes, isoprenoid aliphatic alkanes pristane and phytane, and polycyclic alkanes of the sterane and terapane type. On the other hand, in the environmental chemistry, these compounds can significantly contribute to the identification of petroleum pollutants, as well as to the assessment of the migration mechanism and the intensity of biodegradation. This review paper first presents the results related to the application of BMs in the organic geochemical correlations of oil in the south-eastern part of the Pannonian Basin (I). The second part provides an overview of those researches in which the same BMs were used in the identification of oil pollutants and in monitoring their changes during the migration and the biodegradation in rivers and river sediments of Serbia (II).

AB  - The main objectives of this research were to (i) investigate the concentration; (ii) characterize the distribution;
(iii) determine the sources apportionment; (iv) estimate environmental and health risks of heavy metals in soil
from mountain beech forest. A total of 76 soil samples from 20 pure beech forest stands from Bosnia and Her-
zegovina (BA), Bulgaria (BG), Check Republic (CZ), Germany (DE), Italy (IT), Poland (PL), Romania (RO), Serbia
(RS), Slovakia (SK), Slovenia (SL), and Spain (ES) were collected. The content of major elements was measured
by X-ray fluorescence spectroscopy (XRF). The content of heavy metals was measured by inductively coupled
plasma–optical emission spectrometry (ICP/OES). Heavy metals had a specific concentration range, which fol-
lowed in soil samples from depth 0–40 cm the common order (low to high): Hg < Cd < As < Co < Pb < Ni < Cu
< Cr < Zn, and from depth 40–80 cm: Hg < Cd < As < Pb < Co < Ni < Cu < Cr < Zn. The grouping of the
examined parameters according to rock types, soil types, and localities indicated the separation of carbonate
rocks from other substrates, luvisol, and rendzina from other soil types, and samples from BA, SL, and IT from
other localities. According to sources apportionment As, Pb and Zn are of anthropogenic origin, Cd, Co, Cr, and Ni are of geogenic origin, while the middle position of Cu and Hg indicates a combined contribution of both
sources. Elements Cd and Hg indicated severe to extremely severe enrichment with a mean value of 24.3 and
70.6, respectively. Based on the determined values Ni, Cr, As and Cd do not pose a health risk.

AB  - Forests in Europe are currently not endangered by soil erosion. However, this can change with climate change or
with intensified forest management practices. Using a newly established network of plots in beech forests across Europe,
the aims of this study were to (i) distinguish soil properties and erodibility indices in relation to bedrock, (ii) determine geochemical
properties and organic carbon (Corg) influencing erodibility, and (iii) assess the effect of soil depth on erodibility
indices. Seventy-six soil samples from 20 beech forests were collected in 11 countries to quantify soil properties influencing
erodibility indices: clay ratio, modified clay ratio, sodium adsorption ratio, and oxides ratio. The results indicate that the
dominant soil properties, determined by bedrock, that correlate with forest soil erodibility indices are Corg, pH, electrical
conductivity, calcium and sodium ions concentrations, total water-soluble cations, and the percentage of sand. According
to the tested indices, soil susceptibility to erosion follows the order granite > andesite > sandstone > quartzite > limestone.
Deeper soil horizons on granite are more susceptible to erosion than surface horizons are, but this is not the case for
soils on limestones. In conclusion, forest management should consider the predisposition of different soil types to erosion.

abstract = "Forests in Europe are currently not endangered by soil erosion. However, this can change with climate change orwith intensified forest management practices. Using a newly established network of plots in beech forests across Europe,the aims of this study were to (i) distinguish soil properties and erodibility indices in relation to bedrock, (ii) determine geochemicalproperties and organic carbon (Corg) influencing erodibility, and (iii) assess the effect of soil depth on erodibilityindices. Seventy-six soil samples from 20 beech forests were collected in 11 countries to quantify soil properties influencingerodibility indices: clay ratio, modified clay ratio, sodium adsorption ratio, and oxides ratio. The results indicate that thedominant soil properties, determined by bedrock, that correlate with forest soil erodibility indices are Corg, pH, electricalconductivity, calcium and sodium ions concentrations, total water-soluble cations, and the percentage of sand. Accordingto the tested indices, soil susceptibility to erosion follows the order granite > andesite > sandstone > quartzite > limestone.Deeper soil horizons on granite are more susceptible to erosion than surface horizons are, but this is not the case forsoils on limestones. In conclusion, forest management should consider the predisposition of different soil types to erosion.",

AB  - The study investigates the influence of alluvial-lacustrine processes and paleoclimate variations on the distribution of terpenoids and unsubstituted Polycyclic Aromatic Hydrocarbons (PAHs). The XRF, ICP-MS, Rock-Eval, and organic geochemical analyses were employed to investigate thirty Lower and Middle Miocene sedimentary samples from the Prebreza and Čučale formations, collected from boreholes BL3 and BL5, situated in the central part of the Toplica Basin (Serbia). The development of the studied basin part was influenced by alluvial-lacustrine processes, which affected the type of organic matter (OM) and the paleoenvironment. Sandy silt and gravel layers in the profile of the BL3 borehole indicate the contribution of thicker clasts brought by rivers. In the BL5 borehole, there are fine-grained intrabasinal lacustrine sediments in the lower part, and swamp sediments in the upper part. The lowest total organic carbon (TOC) content is in alluvial sediments of BL3 and some lacustrine sediments of BL5. Based on Hydrogen Index (HI) and C/N ratio, various mixtures of terrigenous and algal organic matter are present in the sediments, while an increase in the proportion of terrestrial organic matter with higher HI (Type II kerogen) is recorded in upper parts of both boreholes, which may be related to paleoclimatic changes. Based on Tmax, the OM is immature and/or in the initial stage of maturity. The presence of plant terpenoids and unsubstituted PAHs, which reflected paleoflora and paleoclimate changes, was associated with the suggestion of predominating Type III kerogen in the studied sediments. Various factors influenced the application of gymnosperms/angiosperms parameters. For instance, the progressive aromatization of triterpenoids occurred in the BL5, whereas the process was hindered in the upper part of the BL3, probably as a result of high sedimentation rates. Based on C-value, Sr/Cu, and Rb/Sr ratios, during the deposition of the Lower and Middle Miocene formations of Čučale and Prebreza, a warm and humid climate prevailed, reflecting the Middle Miocene Climatic Optimum (MMCO). The production of unsubstituted PAHs in the studied samples probably relates to paleo-wildfires, anoxic conditions, or the presence of specific biomass precursors. © 2021 Sciendo.

AB  - The Vrbas River is an important river ecosystem in Bosnia and Herzegovina with a length of 250 km and catchment areas of 5900 km2 . Before reaching Banja Luka, the Vrbas River passes through a canyon and numerous gorges, which are from 1955 protected by the Law on the Protection of Natural Values. This river flows through many towns and villages along the entire course, but the main anthropogenic influence comes from Banja Luka, one of the largest cities in Bosnia and Herzegovina.The aim of this research was to characterise extractable organic matter of sediments from the Vrbas River in the city area of Banja Luka. Six samples were collected at locations which were selected based on the vicinity of potential sources of anthropogenic pollution: 1 and 3 – sites near bridge and frequent traffic, 2 – city’s promenade, 6 – site in the vicinity of the thermal power plant, 7 – site close to Banja Luka Brewery and the bridge on frequent road, and 8 – site close to the food industry “Vitaminka”. Extractable organic matter was isolated with dichloromethane/ methanol mixture using a Soxhlet apparatus. Hydrocarbons were isolated from the extracts using a column chromatography and analyzed by gas chromatography – mass spectrometry (GC-MS). Detailed analysis of n-alkanes (m/z 71), diterpanes (m/z 123), hopanes (m/z 191) and steranes (m/z 217) was done. The individual peaks were identified by comparison with literature data [1] and based on their mass spectra (library: NIST11). Among saturated hydrocarbons diterpane, 16α(H)phyllocladane is the most dominant component in almost all samples (Fig.1). The exception is a sample 7. This diterpane is followed by n-alkanes with a predominance of higher odd homologues.  It indicates predominately native organic matter of Vrbas river sediments, originated mostly from terrestrial plants. That was noticed the predominant presence of native organic material in noticed in samples 2, 3, 6, while the presence of oil type pollutants was confirmed in other samples (1, 7, 8), which are near the bridge and frequent traffic roads. Fig 1. Total ion current (TIC) of saturated fraction. The previous study regarding the contents distribution of heavy metals in these sediments showed that most contaminated samples are at sampling points 2 and 6 [2]. That is not the case with oil contamination pointing to probably different sources of anthropogenic pollution.

AB  - The mutual impact of low-quality lignite and high-density polyethylene (HDPE) during open system pyrolysis was investigated, aiming to improve utilization of lignite with simultaneous treatment of HDPE waste. Pyrolysis of lignite, HDPE, and their mixture (mass ratio, 1:1) was performed at temperatures 400, 450, 500, 550, and 600 °C. Initial substrates and pyrolysis products were characterized by thermogravimetric analysis (TGA), gas chromatography–mass spectrometry (GC–MS), specific carbon isotope analysis of individual hydrocarbons (δ13C), Rock-Eval pyrolysis, and elemental analysis. The positive synergetic effect during co-pyrolysis of lignite/HDPE mixture was observed at temperatures ≥450 °C, with the greatest being at 500 °C. The highest yield of liquid co-pyrolysis products with a similar composition to that of crude oils is also noticed at 500 °C. The yields of liquid and gaseous products and quality of pyrolytic products obtained by co-pyrolysis of lignite/HDPE mixture are notably improved compared with pyrolysis of lignite alone. On the other hand, data obtained from pyrolysis of HDPE alone indicate that it cannot be concurrent to well-developed catalytic thermal processes for polymer recycling. However, concerning the huge amount of produced HDPE, at least part of this plastic material can be reused for advanced thermal treatment of lignite, particularly in countries where this low-rank coal represents the main source of energy.

AB  - The paper briefly presents goals, activities, challenges, and outcomes of the NETCHEM project (http://www.netchem.ac.rs/) that was co-funded by the Erasmus+ Program of European Union (573885-EPP-1-2016-1-RS-EPPKA2- CBHE-JP). The project has been started in October 2016 and with extension lasted until April 2020. Western Balkan region has been targeted by upgrading capacities for education and research in environmental and food analysis in cooperation with partners from France, the UK, and Czech Republic. NETCHEM platform providing Web Accessed Remote Instrumental Analytical Laboratories (WARIAL) network, Database service and Open education system was created in order to improve the cooperation, educational, and research capacities of Higher Education Institutions involved, but also targeting whether audience not only from academic domain but from industry as well. The NETCHEM platform is free for access to public; thus, the external users to NETCHEM consortium can not only see its content but also actively participate, enter Database and WARIAL network, and upload their own educational/research material.

AB  - The objective of this study is geochronological investigation of sedimentological and inorganic composition, in the Danube Djerdap Lake sediments in order to obtain reliable information about former pollution. Eleven samples were taken from the 135-cm-deep sediment core drilled at the Orlova location. Since the core represents sediments deposited during 1972–2016, the sedimentation rate of ~ 3 cm year−1 was estimated. Grain size, mineralogical and geochemical composition was determined. Sediments are sandy silts and clayey silts, and only the deepest and shallowest layers contain > 30% of sand-size fraction. The highest concentrations of minor elements are found in the oldest sediment (1972–1977) as a consequence of the high flux of the material from variable sources. During the sedimentation period (1975–1990), the concentrations of analyzed elements are generally decreasing until the beginning of 1990s. After this period, there are two distinct decreases and two distinct increases in concentrations of elements. The fluctuations in minor element concentrations are a consequence of both natural and anthropogenic sources. Granitic rocks situated south are source of minerals that carry minor elements. Enrichment Factor, Geoaccumulation Index, Contamination Factor and Pollution Load Index indicate that concentrations of certain minor elements at specific depositional periods have anthropogenic source.

AB  - Analysis of limnic sediments can serve as a tool to assess sedimentary pollution for both the status quo as well as changes over time. However, in environmental studies, often only a small number of established well-studied contaminants are considered. This study focused on a more comprehensive investigation of sedimentary pollution of Djerdap Reservoir. Therefore, complementary analytical approaches were applied covering lipophilic organic contaminants and heavy metals. Investigations were performed on limnic sediment layers representing a period of 43 years of reservoir functioning. The core was sectioned on 11 samples and analyzed for, loss on ignition (LOI), and organic compounds (gas chromatography-mass spectrometry). Here, we report the quantitative data of 43 lipophilic organic compounds indicating both domestic and industrial emissions. Measured concentrations are generally low. Surprisingly, no polychlorinated biphenyls have been detected. Data concerning grain size, sedimentological, and inorganic composition were measured and published by in Kasanin-Grubin et al. (Kasanin-Grubin et al. 2019).

AB  - In this thesis oil shale and bitumious marlston samples from the Upper layer of Aleksinac deposite (block Dubrava) were investigated. Within the investigation done in this thesis the Upper layer of oil shale, which is considerably thicker and more accessible, thus easier for exploitation and processing, was for the first time geochemically characterized in more detail.The examinations of organic matter (OM) has shown that it is significantly preserved, formed mainly from algae precursor organisms with a certain input of higher terrestrial plants, deposited in reduced lacustrine alkaline brackish to freshwater environment, and it is in low degree of maturity. The OM of most analysed samples predominantly contains kerogen types I and/or II. These types of kerogen have high hydrogen content and therefore have a high potential for generation of liquid hydrocarbons.Based on the degree of enrichment (Ki) and enrichment factor (EF) it was found that the investigated samples are enriched only in Mo and Cs.Analysing the most potential samples it has been determined that a higher yield of shale oil is obtained in the open pyrolysis system in comparison to the closed one. The yields of hydrocarbons in pyrolysates from the open system correspond to the values for excellent source rock potential, while in the closed pyrolysis system indicate very good potential. The obtained results showed that the quantity of OM has a greater impact on the shale oil generation than the kerogen type in the open pyrolysis system, while in the closed system in conditions, which more intensively simulate maturity changes of OM, the situation is reversed.The composition of obtained shale oil has certain undesirable characteristics due to the relatively high content of olefins (open system) and polar compounds (closed system), which may require additional treatment prior to use and increases the price of the entire process of obtaining shale oil.

AB  - A detailed evaluation of geochemical properties of oil shale samples,from the outcrops of the Lower Miocene upper layer in the Dubrava area, Aleksinac basin, Serbia, was performed. For that purpose X-ray diffraction (XRD) analysis, Rock Eval pyrolysis, gas chromatography-mass spectrometry (GC-MS) analysis of biomarkers and conventional pyrolysis in an autoclave were used. Most of the samples have similar mineral compositions with predominance of clay and feldspar minerals. Three samples are characterised by an elevated content of carbonates, and among them one sample has a notable prevalence of this mineral group. This sample also demonstrated certain differences in biomarker distribution. In most samples organic matter (OM) consists predominantly of type I and II kerogens, showing high oil generative potential, whereas three samples, which contain type II kerogen with a certain input of type III kerogen, demonstrated potential to produce both, oil and gas. The OM of all samples is immature and corresponds to the vitrinite reflectance of ca. 0.40%. Biomarker patterns along with Rock-Eval data indicated a strong contribution of aquatic organisms such as green and brown algae and bacteria with some influence of higher plants OM. The organic matter was deposited in a reducing lacustrine alkaline brackish to freshwater environment under warm climate conditions. Preservation of OM was governed by stratification of the water column rather than its height. Tectonic movements that caused the regional tilting of an investigated area and supported minor marine ingression and influx of fresh water played an important role in formation of the sediments. Conventional pyrolytic experiments confirmed that these sediments at the catagenetic stage could be a significant source of liquid hydrocarbons.

AB  - The influence of pyrolysis type on the shale oil generation and its composition was studied. Different methods such as Rock-Eval pyrolysis, thermogravimetric analysis (TGA) and pyrolysis in the open and closed systems were applied. Samples from the Upper layer of Aleksinac oil shale (Serbia) were used as a substrate and first time characterized in detail. The impact of kerogen content and type on the shale oil generation in different pyrolysis systems was also estimated. Majority of the analysed samples have total organic carbon content  gt 5 wt. % and contain oil prone kerogen types I and/or II. Therefore, they can be of particular interest for the pyrolytic processing. The thermal behaviour of analysed samples obtained by TGA is in agreement with Rock-Eval parameters. The pyrolysis of oil shale in the open system gives higher yield of shale oil than the pyrolysis in the closed system. The yield of hydrocarbons (HCs) in shale oil produced by the open pyrolysis system corresponds to an excellent source rock potential, while HCs yield from the closed system indicates a very good source rock potential. The kerogen content has a greater impact on the shale oil generation than kerogen type in the open pyrolysis system, while kerogen type plays a more important role on the generation of shale oil than the kerogen content in the closed system. The composition of the obtained shale oil showed certain undesirable features, due to the relatively high contents of olefinic HCs (open system) and polar compounds (closed system), which may require further treatment to be used.

AB  - In this paper an applied organic geochemical approach in studying the nature of organic matter (OM) in water and sediments of the River Ibar (upsteream and downstream of towns Kosovska Mitrovica and Kraljevo) was used. A forensic approach that relies on the fact that the composition of OM of recent sediments and oil varies due to geological age and maturity was applied. The content of bitumen, its group composition of saturated, aromatic and NSO compounds (nitrogen, sulphur, and oxygen compounds) and the distribution of n-alkanes in saturated fractions identified by gas chromatography-mass spectrometry (in almost all samples incorporated into the colloidal micelles formed by water and NSO compounds) could not answer the question whether OM in isolated extracts has native or anthropogenic origin. However, the presence of sterane and terpane, with the distribution of structural and stereochemical isomers characteristic of oil, as a form of most matture OM in sediments, unambiguously confirmed presence of oil type pollutants in anlayzed samples. Based on significant differences in the distributions of these polycyclic alkane (water-water, sediment-sediment and water-sediment), it was concluded that they have more than one source of pollution, and that the River Ibar is permanently exposed to this form of pollution.

AB  - On a global scale, it was found that the surface of the vulnerable land and land affected by degradation has been increasing in the last decades and that unsustainable land management is one of the key drivers of land degradation. In order to assess the effect that these changes have on biodiversity and ecosystem services, and to realize appropriate planning and management actions for the conservation of the environment, it is essential to identify and quantify changes caused by land degradation. The aim of this study was to determine the impact of the geological setting, i.e., the type of bedrock, and land use on the physicochemical properties of soil in the vulnerable mountainous areas of Fruska Gora. For the purpose of this study, 30 soil samples were collected from a depth of 0-20 cm at four locations on the Fruska Gora Mt. The geological setting was serpentinite and marl and land cover was forest and meadow. The following soil properties were determined: pH, redox potential (Eh), electrical conductivity (EC), total dissolved solids (TDS), concentrations of available cations Ca, Mg, K, Na, contents of organic carbon (Corg) and nitrogen (N). The correlation between the obtained parameters was tested with two-way ANOVA and principal component analyses (PCA). All of the obtained results indicated that the soil physicochemical properties depended on the geological setting and that rock composition has to be taken into consideration during land management.
