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  - The investigation of the relationship between paleoenvironmental conditions and distribution and relative abundance of specific saturated and aromatic hydrocarbons was the main objective of this study, thus marking the parameters, which were most sensitive to environmental changes. Insights on the type, generative potential, and maturity of organic matter (OM), as well as paleoclimate conditions, along with the reconstruction of depositional settings of the northwest part of the Toplica basin (Serbia), were provided. Organic petrographic, palynofacies, organic geochemical, mineralogical, and XRF analyses were carried out to investigate 40 sediment samples of the Prebreza and Čučale sedimentary units. Investigated samples were deposited in the saline and anoxic environment, under semi-arid to semi-humid/humid climate conditions, along with the constant inflow of volcanoclastic material. The predominance of δ-methyltrimethyltridecil chroman (δ-MTTC) within euxinic portions of the stratified water column was associated with an increase in salinity, which was noticed for sediments of the Prebreza unit. Sediments from this stratigraphic unit showed a higher contribution of algae precursor, whereas sediments of the Čučale unit suggested higher participation of microbiologically reworked OM. Most of the samples contained oil-prone kerogen type II. Maturity of the OM for sediments of the Prebreza unit ranged from immature to early-mature, while for samples of the Čučale unit varied from early-mature to mature stages. Distribution of hopane biomarkers typical for crude oil indicated that depth of 1 km was a boundary for the genesis of thermodynamic, more stable compounds. A significant portion of semifusinite was correlated with the paleofire event, which affected the distribution of n-alkanes. The high production of hydrocarbons was related to volcanic activity. Parameters, which proved to be highly susceptible at the stratigraphic boundary between the Prebreza and Čučale units, were C-value, S/H, α-MTTC, δ-MTTC, β-/γ-MTTC, and (1,3- + 1,6-)/(1,4 + 1,5-DMC), respectively.

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.

abstract = "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.",
