AB  - In Sečovlje Salina Nature Park, the therapeutic mud matured in the natural sedimentary environmental site. This work aimed to determine the influence of the peloid maturation process on the hydrocarbon and elemental distributions, as well as changes in morphology. For this purpose, the sample before and after maturation was examined using various methods. n-Alkanes were the most abundant among saturated hydrocarbons in both immature and mature peloid samples. The results showed that the maturation mainly influenced the change in distribution and concentration (from 378 to 1958 ppm) of n-alkanes. The organic matter (OM) of the immature peloid sample was characterized by a slight prevalence of long-chain and odd carbon-numbered n-alkanes, maximizing at n-C27. However, mature peloid's OM showed a similar share of short-, mid- and long-chain n-alkanes with a slight dominance of short-chain members, maximizing at n-C16. The origin of short-chain and even carbon-numbered n-alkanes was attributed to microbial precursors (e.g., Leptolyngbyaceae). Hopanes were considerably more dominant compared to steranes in both peloids. The hopane series of immature peloid was characterized by the dominance of 22,29,30-trinor-hop-5(6)-ene (C27 hopene), as well as the presence of C30-hop-22(29)-ene (diploptene), which are widespread in cyanobacterial species. The aromatic fraction of immature peloid pointed to the predominance of polycyclic aromatic hydrocarbons (PAHs). As peloid aging progressed, the sample was richer in methyl-branched alkanes, carboxylic acids, their methyl esters, and thermodynamically more stable hopanes and steranes. The presence of elements with toxicological relevance during maturation was reduced below the limits prescribed in most of the directives for cosmetic products. It specifically refers to: As, Ni and Se. A higher concentration of total sulfur in the mature peloid can be related to gypsum precipitation in the summer and/or more intensive microbial activity.

AB  - The aim of this study is to investigate the influence of weathering processes on the distribution of n-alkanes in unweathered and weathered samples of badland material. Organic matter (OM) of both the weathered and unweathered zones in badland environments is derived from the same sources such any differences between the n-alkane pattern of the two zones can be attributed to the impact of weathering processes under different climate conditions. Organic geochemical and mineralogical characterizations were employed to investigate twenty-one samples from weathered badland environments in Italy, Spain, and Canada that originally derive from marine, distal alluvial, and fluvial depositional settings, respectively. According to the distribution of n-alkanes and diterpanes, unweathered samples from Italy have an original mixed aquatic-terrestrial origin of OM, with a variable (low to moderate) contribution of terrestrial plants as precursors, while unweathered samples from Spain predominantly contain OM originating from submerged/floating macrophytes deposited under reducing conditions. Unweathered samples from Canada predominantly consist of terrigenous OM. Intensity of changes in n-alkanes distribution when subjected to weathering depends on the type of precursor biomass and quantity of smectite. Predominantly terrigenous OM under semi-arid conditions shows the highest affinity for adsorption is in contact with smectite surfaces. Mid- and long-chain odd n-alkanes have a tendency to build colloidal particles with polar organic compounds such as fatty acids by strong binding and thus their preservation from degradation is possible.

AB  - A diversity of factors, led by lithology, weathering, and erosion processes, plays a significant role in the formation and future of badland terrains. Then on previous observations it can be concluded that surface flow processes are the first trigger of erosion and that intense soil erosion combined with rapid and deep weathering are tightly connected to high erosion rates.Since climate change presents a global issue that gains increasing attention and due to the complexity of the interactions and processes that are a part of general badlands origin and evolution, a weathering experiment on badland sediments from China was conducted. Explaining temporal changes, the impact of different precipitation types and its durations of exposure on sediments during weathering processes, as well as its impact on leachate ions behaviour are the aims behind this experiment.Red clayey siltstone and mudstone badland sediments selected for the laboratory experiment were organized in four sets that included three different samples, making a total of 12 treated samples. Based on field climate data, in laboratory conditions samples were exposed to rain, acid rain, snow, and acid snow through fifteen daily cycles. Leachate was collected after each cycle and its volume, pH, electrical conductivity (EC), and ion concentrations were measured and analysed from the leachate. Changes occurring on the surface of the sample were observed through photographs taken at the end of each cycle.Based on obtained results it can be said that the main differences occur when comparing rain and snow treatments generally. Temporal, cyclic changes were, to a certain extent, noticed through sediment decay. More importantly, durations of sediment exposure to precipitation proved to be crucial for weathering processes of tested siltstones and mudstones, having exclusion and ionic forces - ion exchange chromatography as dominant chemical processes.

AB  - Crude oil samples from the Sharara-C oil field (Concession NC-115, Murzuq Basin, SW Libya) were analysed by organic geochemical methods in order to infer the geochemical characteristics of their respective source rocks. Aromatic hydrocarbons were analysed by gas chromatography – mass spectrometry (GC-MS), and gas chromatography – tandem mass spectrometry (GC-MS-MS) was used to analyse saturated biomarkers. The Sharara-C oils are interpreted to have been generated by marine shales containing mixed terrigenous and marine organic materials deposited in an intermediate (suboxic) environment. Age-specific biomarker ratios indicated that the oils are older than Cretaceous, and maturation-related parameters pointed to their high thermal maturity. Consistent with previous studies, source rocks are inferred to be “hot” shales in the Lower Silurian Tanezzuft Formation. Almost all the parameter ratios calculated varied over a very narrow range, indicating that the investigated oils were compositionally similar. The only significant difference that was noted concerned the sterane/hopane ratios whose variation suggested that there was some variability in the composition of the source organic material. The organic geochemical parameters determined for the Sharara-C crude oils were compared with published data on other crude oils from Concession NC-115. Almost all the parameters agreed well with previously published data on oils from this part of the Murzuq Basin. The greatest deviation concerned the values of some of the maturity parameters. This tended to confirm the conclusions of previous studies concerning the presence of a number of distinct oil families and sub-families in the Sharara oil field area which are genetically related but which have different maturities.

Petroleum desulphurisation catalysts can also be hazardous refinery waste. They contain various metals, such as cobalt, molybdenum, nickel and tungsten. In this paper, three petroleum refiner’s spent desulphurisation catalysts were investigated. These catalysts were not suitable for recycling and, therefore, were classified as hazardous waste. They were chemically characterised, including phase composition and their effect on a consortium of microorganisms used in the process of bioremediation. Catalysts contained up to 2.26 g kg−1 of total petroleum hydrocarbons, up to 56.7 g kg−1 of iron, 18.6 g kg−1 of molybdenum, and less than 0.1 mg kg−1 each of cobalt and nickel. These obtained results show that bioremediation of such waste is possible.

AB  - The main objective of this study was to analyze the capacity of Cedrus atlantica (Endl.) Manetti ex Carrière 1855 to accumulate macro- and microelements in order to assess the environmental status. The element concentrations were measured using X-ray Fluorescence (XRF) analysis. The obtained pH values in this study show that the urban soils are neutral to slightly alkaline with low OM content. Macroelements with the highest mean concentrations in soil are Si, Al, Fe, K, Mg, and Ca. The ratio > 2 was determined for mean concentrations of Ca in the soil and Mg in needles from the Zvezdara forest, and for mean concentrations of Cl, Ti, and Fe in needles from the Byford’s forest in relation to the reference site. The accumulation pattern of the macroelements based on the Biological Concentration Factor (BCF) values > 1 for needles is for P, S, Cl, and Ca. Microelements with the highest mean values in soil are Ba, Zr, Ce, Cr, Zn, Rb, Sr, V, and La. Microelements with the highest mean values in Atlas cedar needles are Ce, La, Ba, and Cs. The ratio > 2 was determined for Cr and V concentrations in the needles from the Byford’s and Zvezdara forests and for Cu concentrations in needles from the Byford’s forest in relation to the reference site. The accumulation pattern of the microelements based on the BCF for needles is higher for I, Cs, Mo, Ag, Cd, In, Sn, Sb, and Tl. Since differences in the concentrations of macro- and microelements in the urban areas and the reference site can be identified C. atlantica can be recommended for assessing the environmental status.

AB  - With the objective to quantify the Neogene extensional geodynamic drivers of the Peri Pannonian Realm s.l., a series of 1D basin models were carried out by integrating the available geological and geochemical data extracted from the landlocked Toplica Basin (central-southern Serbia; Serbo-Macedonian Unit). The modeling was conducted on four wells located immediately south of Jastrebac Mt., in the area of the Toplica Basin. The investigated southernmost point of the Peri Pannonian Ream s.l. (areas surrounding the basin, to the south of rivers Danube and Sava) underwent intense tectonically-driven subsidence episodes, which lasted from the Lower Miocene up to the Pliocene. The restored Neogene burial history (subsidence rates), paleotemperature, and calibrated paleo-heat fluxes (or changes in the ancient crustal or basal heat flow) indicated a two-staged crustal stretching of the wider Toplica area. The combined tectonic, i.e., thermal subsidence, resulted in a very high sedimentation rate, having an average ca. 300–400 m/Ma (Čučale unit). The intense tectonically-driven subsidence is consistent with the involvement of extensional processes, affecting the crustal and lithospheric layers of the retreating Adria/Dinarides, amplified by a distant Carpathian rollback stage. The regional extension led to the asymmetric opening and the formation of the Toplica Lower Miocene mesosaline to the freshwater lacustrine system. Higher participation of mixed microbiologically reworked/terrestrial organic matter incorporated in oil-prone Type II kerogen mainly characterized the investigated lacustrine sedimentary sequence. The latest Oligocene–earliest Neogene subsidence onset was characterized by elevated temperatures, affecting the early development of the oil window (ca. at 16 Ma). The 1D models also showed that the Lower Čučale unit achieved ca. 50% transformation ratio for the Type II organic matter. The two intra-Neogene extensional episodes suggested the existence of the Early Neogene “syn-rift” stage, followed by a thermal sagging. The Neogene continuous thinning of the overriding Serbo-Macedonian continental crust contributed to the “negative inversion” of the former pre-Neogene nappes. Therefore, Neogene tectonic reactivation induced contemporaneous subsidence, further allowing the extensional rise of the Jastrebac core complex.

AB  - The oil pollutant in the Sava River aquifer in the residential area of Belgrade, Serbia was investigated in order to analyze the extent, origin and spatial distribution of the pollution, with the aim to estimate potential human health risks from exposure to the compounds detected. Analytical methods indicated that the dominant compounds in this oil pollutant were gasoline range organic compounds. Benzene, toluene, ethylbenzene and xylenes (BTEX) were identified as compounds of concern and quantified by headspace gas chromatography. The concentrations of benzene measured at all sampling points were higher than the remediation value while the maximum concentrations of BTEX quantified were among the highest concentrations of these compounds reported in the petroleum-contaminated aquifers in the world. The assessment of the human health risks from exposure to BTEX-covered industrial scenario for adult receptors and residential scenario for adult receptors and children. The exposure routes analyzed were dermal contact with and ingestion of contaminated water, considering both cancer and non-cancer effects. The analysis of the lifetime incremental cancer risk indicated the potential for adverse health effects for human exposure at the investigated location, and because of that it was interpreted as an unacceptable risk level or risks of high priority which required immediate consideration for remedial measures at this location. A complete set of mitigation measures was proposed including: groundwater decontamination treatment, installation of filters for tap water, development of the system for monitoring of BTEX in the groundwater and development of the emergency response capacities at this location.

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.

abstract = "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  - Abstract
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 hydrocar-
bons 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.

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  - Heavy metals are naturally occurring elements, but they are regarded as significant environmental pollutants due to their high density and high toxicity even at low concentrations. The aim of this paper is the evaluation of the pollution level of heavy metals in the river and riverbank sediments, as well as the estimation of their origin and spatial differences along the course of the Vrbas River through Banja Luka. The concentrations of metals have been assessed using the Inductively coupled plasma – optical emission spectrometry and Advanced mercury analyzer for mercury determination. The anthropogenic impact on heavy metal concentration in sediments was estimated by the calculating of pollution indices: geoaccumulation index (Igeo), contamination factor (Cf), pollution load index (PLI) and potential ecological risk index (Er). Obtained results indicate that there is no statistically significant spatial difference in metal concentration, indicating that heavy metals in sediments have a constant source. The anthropogenic impact expressed by the values of pollution indices showed that sites are generally uncontaminated by Co, Cr and V and moderately contaminated by Zn, Cu and Ni. On the contrary, lead, mercury and cadmium pose the highest ecological risk. The anthropogenic source of Pb, Hg and Cd is industry, municipal waste and the combustion of fossil fuels. The obtained results demonstrate the high ecological risk and the need for environ-mental monitoring, with the aim to support an efficient strategy to reduce local pollution and contamination of the investigated system.

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 Techirghiol Lake, located on the Romanian coast of the Black Sea, is a hypersaline lake. In this environment, a unique ecosystem in Europe has developed with the specific capacity of producing mud by the decomposition of flora and fauna under the microbial activity (saprogenic sludge), which is used for therapeutic purposes.In this study, hydrocarbon compositions of the Techirghiol Lake mud are investigated in order to determine the origin and type of organic matter (OM). All samples are characterized by a high abundance of n-alkanes, short and high chain alkenes, pimarane, phyllocladane, indicating that OM was mainly derived from phytoplankton, filamentous green alga Cladophora vagabunda, Cyanobacteria, submerged/floating macrophytes, terrestrial and emergent plants. The terrestrial origin of organic matter is probably related to a significant input by wind or rivers. Typical oil distributions of terpanes and steranes biomarkers clearly indicate that the muds of Techirghiol Lake, in addition to native organic matter, contain a relatively low contribution of petroleum type pollutants, as well as PAH compounds of pyrogenic origin. The relatively high abundance of 1-chloroalkenes, which in some samples represent the most abundant compounds in the total distribution of hydrocarbons, together with isoprenoid thiophenes indicate the local presence of significant amounts of chloride and sulphur species in the water column or surface sediment.

AB  - Badlands are areas with limited vegetation, reduced or no human activity, and a great variety of geomorphic processes [1]. Badland materials have a different responsetothe same environmental conditions, because of differences in their mineralogical and physico-chemical characteristics. Many studies show that smectite-poorsediments are more resistant to different weathering treatments of freezing, thawing, wetting, and drying,than smectite-rich materials [2,3].In this paper, three unweathered samples of badlands from Spain were analyzed with the aim of monitoring, but also comparing physico-chemical changes caused by simulations of changes in climatic conditions. Selectedsediment samples havedifferent compositions. Besides quartz and calcite, the first sampleis composed of smectite and gypsum (3 UW), the second of smectite (4 UW), while the third sample is composed of neither smectite nor gypsum (5 UW). The experiment setup was designed in the way that each sample had three sub-samples, a sample for simulation of rain, snow, and a control sample (Figure 1). Sample_rain was treated with a rain intensity of ~850 ml/h for 10 minutes (~140 ml), while sample_snow was treated with crushed ice (~150 g). After precipitation simulations snow were put samples were placed in a climate chamber at - 3 °C together with a control sample. This was repeated for 15 cycles. Every cycle was documented with photographs. The leached solution was collected and its volume, pH, electrical conductivity (EC), and ion concentrations were measured. The second part of the experiment was based on exposing the samples after wetting to higher temperatures, 50 ° C. It was done in 8 cycles. FESEM and BET analyzes were performed for each sample before and after the experiments.The 3 UW samples had significantly different leachate pH and EC, while the leachate volume was similar for all samples during the experiment. Sulphate ions were leached in the highest concentrations during the whole experiment from the sample with both smectite and gypsum present. The sample with smectite has shown the highest disintegration of the structure, especially after the simulation of snow. The sample with smectite and gypsum has shown a lower degree of degradation than sample 3 UW due to the content of gypsum which increases the weathering resistance of the material. Sample 5 UW has shown the lowest degradation of the structure along with the weathering cycles. This study has proven that both mineralogical and physico-chemical properties of sediments are important for predicting their response to variable climate factors.

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  - Badlands are areas with scarce or completely absent vegetation formed in a wide range of lithologies in different climate conditions and exposed to a wide range of geomorphological processes [1]. Generally, rapid evolution governed by erosion processes is a consequence of complex mineralogical and physico-chemical sediment composition and climate conditions. Because of that, badlands are often described as natural field laboratories and, furthermore, badland material is suitable for laboratory experiments that can, in controlled conditions, provide insight of changes that occur in the field. As indicated above, beside lithology, climate is one of the most significant factors in badlands forming. Since human activities have great impact on the environment and since climate changes present one of the biggest environmental pollution problems nowadays, in this research badland material was exposed to different conditions with the aim of monitoring changes caused by extreme climate conditions and acid ice. Three samples from badlands in China organized in six sets were treated with ice (representing snow) and acid ice (frozen acid rain) during fifteen cycles, dried in the oven for three cycles and afterwards again threated with ice and acid ice for additional five cycles. After each cycle samples were photographed, so that physical changes can be tracked, while leachate was collected and analyzed for monitoring changes in its volume, pH, electrical conductivity (EC) and cation concentration. Beside slight oscillations in parameters through cycles of samples treated with acid ice, extreme changes in observed parameters were not noticed neither between samples, nor between treatments. Leachate EC were a bit higher in samples treated with ice, leachate volume was higher for samples treated with acid ice, while pH was similar in both cases. Cation concentrations are similar in the leachate of all tested samples. In most of cases, the highest concentrations were measured at the beginning of the experiment, during the first two cycles or during the first “ice” cycles after drying. This indicates the high cation concentrations originate from the sediment surface or washing along the crack that appeared after drying. Physical changes that occurred through cycles implied that heat/drought is more aggressive agent of sediment decay. Decay caused by ice is slower, not as aggressive as drought, but not negligible, causing noticeable and significant cracks and fissures of fragments.  This experiment confirmed that drought has high impact on sediment weathering, but more importantly, pointed out the impact of ice and its thawing, opening new questions about climate impact on forming, erosion processes and evolution of badlands which need to be further examined.

abstract = "Badlands are areas with scarce or completely absent vegetation formed in a wide range of lithologies in different climate conditions and exposed to a wide range of geomorphological processes [1]. Generally, rapid evolution governed by erosion processes is a consequence of complex mineralogical and physico-chemical sediment composition and climate conditions. Because of that, badlands are often described as natural field laboratories and, furthermore, badland material is suitable for laboratory experiments that can, in controlled conditions, provide insight of changes that occur in the field. As indicated above, beside lithology, climate is one of the most significant factors in badlands forming. Since human activities have great impact on the environment and since climate changes present one of the biggest environmental pollution problems nowadays, in this research badland material was exposed to different conditions with the aim of monitoring changes caused by extreme climate conditions and acid ice. Three samples from badlands in China organized in six sets were treated with ice (representing snow) and acid ice (frozen acid rain) during fifteen cycles, dried in the oven for three cycles and afterwards again threated with ice and acid ice for additional five cycles. After each cycle samples were photographed, so that physical changes can be tracked, while leachate was collected and analyzed for monitoring changes in its volume, pH, electrical conductivity (EC) and cation concentration. Beside slight oscillations in parameters through cycles of samples treated with acid ice, extreme changes in observed parameters were not noticed neither between samples, nor between treatments. Leachate EC were a bit higher in samples treated with ice, leachate volume was higher for samples treated with acid ice, while pH was similar in both cases. Cation concentrations are similar in the leachate of all tested samples. In most of cases, the highest concentrations were measured at the beginning of the experiment, during the first two cycles or during the first “ice” cycles after drying. This indicates the high cation concentrations originate from the sediment surface or washing along the crack that appeared after drying. Physical changes that occurred through cycles implied that heat/drought is more aggressive agent of sediment decay. Decay caused by ice is slower, not as aggressive as drought, but not negligible, causing noticeable and significant cracks and fissures of fragments.  This experiment confirmed that drought has high impact on sediment weathering, but more importantly, pointed out the impact of ice and its thawing, opening new questions about climate impact on forming, erosion processes and evolution of badlands which need to be further examined.",

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 investigated the influence of maturity, biomass type, and depositional settings on the distribution and relative abundance of polycyclic aromatic hydrocarbons (PAHs) for lacustrine sediments collected from depths up to 1000 m of Prebreza and Čučale stratigraphic units (the northwest part of the Toplica Basin). A recently proposed benzo[ghi]perylene/(perylene + benzo[ghi]perylene) parameter, along with commonly used Phenanthrene Alkylation Index and benzo[e]pyrene/(perylene + benzo[e]pyrene) indices, pointed out differences in maturity levels between stratigraphic units by displaying a positive linear relationship with vitrinite reflectance. However, in several immature Prebreza sediments, a substantial presence of algae and/or anoxic, mesosaline/hypersaline conditions were suitable for forming β-substituted methylphenanthrenes and 6-ring benzo[ghi]perylene. Generally, high molecular weight unsubstituted PAHs (HMWPAHs), particularly perylene, predominated Prebreza sediments. Anoxic conditions appeared to be decisive for accumulating and preserving the perylene carbon skeleton in studied stratigraphic units. Besides, more intense volcanism in the Čučale unit favored combustion processes, which prompted the accumulation of low molecular weight unsubstituted PAHs (LMWPAHs), especially phenanthrene. A general prevalence of retene over cadalene in Prebreza sediments, in which alginite and liptodetrinite predominated, implied algae as retene precursor. Selective degradation of retene or hindered demethylation of 9-methylphenanthrene under anoxic and more saline environmental settings had occurred notably in the Prebreza unit, which led to the formation of 1-methylphenanthrene and/or pimanthrene (1,7-dimethylphenanthrene). Čučale sediments with substantial amounts of vitrinite macerals or saturated diterpenoids had a predominant simonellite derived from conifers. Non-degraded and well-preserved Pinaceae conifers predominated in Prebreza sediments deposited under semi-arid climatic conditions, whereas mixed degraded/non-degraded conifers characterized Čučale sediments deposited in a wide range of climatic conditions, from semi-arid to semi-humid. © 2021, The Author(s), under exclusive licence to Springer Nature B.V.
