AB  - Soil erosion is a problem that affects the landscape at different scales and represents a serious challenge for land management and soil conservation in both natural forests and meadows. The aim of this study was to determine how the parent material and land use affect the physical and chemical properties of the soil in the area of the Fruska gora Mountain. The soils were developed on five bedrock types: serpentinite, marl, trachyte, shale, loess and two land use types: forest and meadow. Twenty-three forest soil and 24 meadow soil from a depth of 0-20 cm were sampled from the Fruska gora Mt. Following properties were determined: pH, electrical conductivity, oxidation-reduction potential, content of organic carbon, sodium adsorption ratio, aggregate size and stability. There is no statistically significant difference in pH, Eh, EC, and SAR values between the analyzed forest and meadow soils, but there is a statistically significant difference in the content of Corg. It can be conculded that both the parent matrial, and to a slightly less extent, land use have a great influence on physico-chemical properties of the soil.
AB  - Ерозија земљишта је проблем који утиче на пределе у различитим размерама и представља озбиљан изазов за управљање земљиштем и очување земљишта како у природним шумама тако и на ливадама. Циљ овог истраживања био је да се утврди како матична стена и начин коришћење земљишта утичу на физичко-хемијске особине земљишта на подручју Фрушке горе. Земљишта су развијена на пет типова стена: серпентинит, лапорац, трахит, шкриљац, лес, као и на два начина коришћења терена: шума и ливада. Са Фрушке горе узоркована су 23 шумска земљишта и 24 ливадска земљишта са дубине од 0-20 цм. Одређена су следећа својства: pH, електрична проводљивост (EC), оксидо-редокс потенцијал (Eh), садржај органског угљеника (Corg), однос адсорпције натријума (SAR), величина агрегата и стабилност. Не постоји статистички значајна разлика у вредностима pH, Eh, EC и SAR између анализираних шумских и ливадских земљишта, али постоји статистички значајна разлика у садржају Corg. Може се закључити да на физичко-хемијске особине земљишта велики утицај имају изворни материјал и у нешто мањој мери начин коришћење земљишта.

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 confluence. The position of GWI causes a large number of possible hydrocarbons inputs that influence 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 flow 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 specific wetland site). The grain size was determined using a standard wet sieving procedure. The extractable organic matter (OM) was quantified 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 chromatography-mass 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 confirmed 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 runoff.

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 runoff.",

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 Herzegovina (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 followed 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  - 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  - Petroleum pollutants and organic waste are both important environmental issues. Biochar is a highly complex and heterogenous material consisting of both organic and inorganic compounds obtained by thermal degradation of organic wastes. Using biochar for removal of petroleum pollutants could decrease the environmental impact of both petroleum pollutants and organic waste. Furthermore, immobilising microorganisms on biochar could increase removal trough the effect of biosorption and eventually biodegradation. The aim of this research was to examine the efficiency of removal of petroleum hydrocarbons using biochar, microbial consortium and their
combination. Microorganisms were isolated from soil polluted with hydrocarbons and enriched on media supplemented with diesel, while two biochar samples (made from wheat straw pellets and sewage sludge) were used as adsorbers and carriers for immobilization of these hydrocarbon degrading microorganisms.
The remediation study was performed on water samples prepared in laboratory condition by adding crude oil and minerals into the distilled water. The period of the remediation was 96 days, while the analysis of the removal and degradation of petroleum pollutants was performed every 32 days for each sample.
Measurement of the removal of total petroleum pollutants was followed gravimetrically measuring fraction of extracted soluble organic matter, separated saturated and aromatic fractions of crude oil that remained in water phase. Furthermore, saturated and aromatic fractions were analysed by GC-MS. From the obtained results it can be seen that more than 99% of crude oil was removed from numerous water samples and that microorganisms primarily degrade n-alkanes over other groups of compounds.
In further studies, if method effectiveness proven successful, should be tested on real samples and it should be scaled up for industrial purposes.

Furthermore, immobilising microorganisms on biochar could increase removal trough the effect of biosorption and eventually biodegradation. The aim of this research was to examine the efficiency of removal of petroleum hydrocarbons using biochar, microbial consortium and their
combination. Microorganisms were isolated from soil polluted with hydrocarbons and enriched on media supplemented with diesel, while two biochar samples (made from wheat straw pellets and sewage sludge) were used as adsorbers and carriers for immobilization of these hydrocarbon degrading microorganisms.
The remediation study was performed on water samples prepared in laboratory condition by adding crude oil and minerals into the distilled water. The period of the remediation was 96 days, while the analysis of the removal and degradation of petroleum pollutants was performed every 32 days for each sample.
Measurement of the removal of total petroleum pollutants was followed gravimetrically measuring fraction of extracted soluble organic matter, separated saturated and aromatic fractions of crude oil that remained in water phase. Furthermore, saturated and aromatic fractions were analysed by GC-MS. From the obtained results it can be seen that more than 99% of crude oil was removed from numerous water samples and that microorganisms primarily degrade n-alkanes over other groups of compounds.
In further studies, if method effectiveness proven successful, should be tested on real samples and it should be scaled up for industrial purposes.",

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 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  - 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.

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 objective of this study was to determine the impact of geological substrate and and use on: physico-chemical properties of soil and size and stability of soil aggregates. Seventeen soil samples of forest soil and 30 samples of meadow soil developed on different bed-rock from Fruška Gora slopes were analyzed: forest soil on serpentinites, marls and trachytes, and meadow soil on serpentinites, marls, shale and loess. The Fruška Gora is located in the northern part of Serbia and stretches be-tween the Sava and the Danube rivers. The maximum length of this mountain is 75 km along the east-west direction, and along the north-south direction the maximum width is about 15 km, while the total area is 500 km2. After air drying following parameters were determined on all soil samples: grain size, electrical conductivity (EC), pH, available ions (Na+, K+, Ca2+, Mg2+), sodium adsorption ratio (SAR) [3], and organic carbon (Corg). Aggregate stability was determined using the aggregate size of 2-4 mm. Five grams of material was immersed in water and after 10min water was drained with a pipette and the soil was dried. Percentage of stable aggregates was determined from the weight difference. Analysis of variance was used to determine whether the relationship between tested parameters exists.

AB  - The molecular and isotopic composition of biomarkers in initial bitumen isolated from raw immature oil shale samples from the Lower Miocene Aleksinac Basin (Serbia) and liquid products (LPs) obtained by pyrolysis in open (OS) and closed systems (CS) are studied. The influence of pyrolysis type and variations of kerogen type on biomarkers composition and their isotopic signatures in LPs is determined.The molecular composition of the LPs from the OS pyrolysis is very similar to those in initial bitumen, independently on kerogen type. The LPs from the CS pyrolysis have the distributions of biomarkers similar to those in crude oils generated in an early to main stage of “oil window“. The biomarker data suggests that mixed type I/II kerogen attained slightly higher maturity level by the CS pyrolysis than type I kerogen. The isotopic signatures of n-alkanes in LPs obtained by the OS pyrolysis are isotopically lighter than in initial bitumen, independently on kerogen type, whereas in liquid products from the CS they become heavier; showing more pronounced difference for type I kerogen. The results indicate that δ13C data should be used with caution in interpretation of samples having different maturity and particularly of LPs obtained by different system pyrolysis.

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.

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 ele-mental 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-pyrol-ysis 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 lig-nite/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 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.

abstract = "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  - Mercury (Hg) has been listed as a global high priority pollutant by many international organizations due to its mobility and persistence in the environments and high toxicity to organisms. This research was conducted with the aims to determine: (i) total Hg content (THg) and its spatial distribution in sediments of river Tisa along the river course, (ii) possible sources of THg and (iii) degree of THg pollution in sediments from the river Tisa through different criteria. Total Hg in the sediments ranged from 0.07 to 0.49 mg kg-1, with mean ± S.D. value of 0.26 ± 0.10 mg kg-1. The highest mean value of THg (0.30 mg kg-1) was found in the lower stream, while the lowest (0.13 mg kg-1) was found in the tributary. According to Principal Component Analyses (PCA) strong positive loading of metals in all parts of the river Tisa is mainly controlled from the same sources. These sources are related to anthropogenic activities based on calculated Enrichment Factor (EF) values. Total Hg are higher than background value. According to the Republic of Serbia official standard, THg values of river Tisa sediments were within the range of maximum permissible values. Compared with National Oceanic and Atmospheric Administration (NOAA) guideline, 80.49% of sediment samples indicated that THg in the river Tisa sediments represented minimal and possible risk towards the living organisms. Integrating the results of pollution assessment, it could be concluded that THg in river Tisa sediments in Serbia demonstrates considerable contamination according to Geoaccumulation Index (Igeo), and Contaminant Factor (CF), and high pollution risk according to Potential Environmental Risk Index (PERI).

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.

AB  - Đerdapsko jezero formirano je 1972. godine kada je izgrađena hidroelektrana Đerdap
1 na Dunavu na srpsko-rumunskoj granici. Zapremina jezera je od oko 3.500 miliona m3 sa suspedovanim opterećenjem od oko 8.900 kt a-1. Cilj ovog istraživanja bio je ispitivanje neorganskog sastava sedimenata Đerdapskog jezera sa posebnim akcentom na teške metale u cilju utvrđivanja potencijalnog antropogenog zagađenja u ispitivanim sedimentima. Da bi se dali odgovori na postavljeni cilj sedimenti su uzorkovani iz jezgra dubine 140 cm, tako da sedimentno jezgro predstavlja sedimente koji su se taložili od nastanka jezera do 2016. godine (oko 43 godine). Potom je sedimentno jezgro podeljeno na 11 uzoraka. Sadržaj metala određen je rendgenskom fluorescentnom spektrometrijom (XRF), kvalitativna analiza mineralnog sastava urađena je rendgenskom difraktometrijskom analizom (XRD) i na svim uzorcima je urađena granulometrijska analiza prosejavanjem i pipet analizom. Dobijeni rezultati granulometrijske analize pokazuju da u većini uzorka dominira frakcija ispod 125 μm i da se uzorci uglavnom sastoje od alevrita i glina. Rendgenska difraktometrijska analiza je pokazala da se uzorci sastoje od sledećih minerala: liskuna, hlorita, kalcita, dolomita, feldspata, smektita i kvarca.
Određen je sadržaj sledećih teških metala Ni, As, Cd, Zn, Pb, Cu, Hg, Cr, Mn, Ba, Sr i Co.U koncentracijama ispod detekcionog limita za XRF(1 ppm)nalaze se As, Hg i Cd. Posmatrajući promene koncetracije teških metala sa dubinom isti trend imaju Zn, Pb, Cu, Cr i Mn, dok se Ni, Ba i Sr ponašaju drugačije (Slika 1). Najniže koncentracije teških metala primećene su na dubinama od oko 20 m, dok se najviše koncentacije većine teških metala nalaze na dubinama od oko 40 i 120 m. Ispitivani teški metali ne pokazuju korelaciju sa sadržajem organske supstance i frakcije glina. Nađene koncentracije ispitivanih elemenata u najvećoj meri ukazuju na geološko poreklo, i da je antropogeni uticaj mali. Da bi se dali precizniji odgovori buduća istraživanje biće usmerena ka detaljnijim minerološkim analizama, određivanju dostupnih jona i izotopskom određivanju starosti sedimenata da bi se dali odgovorim o potencijalnom zagađenju ispitivanih sedimenata.

Rendgenska difraktometrijska analiza je pokazala da se uzorci sastoje od sledećih minerala: liskuna, hlorita, kalcita, dolomita, feldspata, smektita i kvarca.
Određen je sadržaj sledećih teških metala Ni, As, Cd, Zn, Pb, Cu, Hg, Cr, Mn, Ba, Sr i Co.U koncentracijama ispod detekcionog limita za XRF(1 ppm)nalaze se As, Hg i Cd. Posmatrajući promene koncetracije teških metala sa dubinom isti trend imaju Zn, Pb, Cu, Cr i Mn, dok se Ni, Ba i Sr ponašaju drugačije (Slika 1). Najniže koncentracije teških metala primećene su na dubinama od oko 20 m, dok se najviše koncentacije većine teških metala nalaze na dubinama od oko 40 i 120 m. Ispitivani teški metali ne pokazuju korelaciju sa sadržajem organske supstance i frakcije glina. Nađene koncentracije ispitivanih elemenata u najvećoj meri ukazuju na geološko poreklo, i da je antropogeni uticaj mali. Da bi se dali precizniji odgovori buduća istraživanje biće usmerena ka detaljnijim minerološkim analizama, određivanju dostupnih jona i izotopskom određivanju starosti sedimenata da bi se dali odgovorim o potencijalnom zagađenju ispitivanih sedimenata.",

AB  - The scale of human impacts on the natural environment is now considerably larger than at any point in history. The concept of geomorphic sensitivity can help to understand the rate, magnitude and nature of landscape adjustment to perturbation in a given natural system. Aim of this research is to show that geochemical and mineralogical data are important factors in determining landscape sensitivity. To test the suggested premise Neogene lacustrine Kremna basin (Serbia) was selected since sediments found in lacustrine basins are usually prone to dispersion and erosion. Furthermore, lacustrine basins often bear fossil and mineral resources and because of that are often undergoing land use changes. For the purpose of this study, samples of serpentinite, carbonates, marly carbonates, oil shale and tuff were analyzed. Besides mineralogical and petrographic analyses, samples were subjected to the weathering experiments. Obtained results indicate that marly carbonates and tuff are most prone to dispersion primarily due to presence of clay minerals. However, oil shale which also contains clay minerals showed minor leaching characteristics due to high content of organic matter. It can be concluded that mineralogical and geochemical characteristics are important for determining landscape sensitivity to erosion processes of an area.
