AB  - The relationships between magnetic susceptibility (MS) and elemental variations have been the focus of considerable study in the fields of environmental assessment. The aim of this study was to apply a rapid and inexpensive, low-field magnetic susceptibility method to stream sediments from Vlasina (Serbia) and Kupa (Croatia) river basins, and discuss the relationships between MS and content of 26 studied elements using statistical approaches. 
In this research, magnetic susceptibility was measured using SM30, a small magnetic susceptibility meter with a very high sensitivity of 1 × 10-7
SI. Inductively Coupled Plasma Optical Emission Spectroscopy was used to determine the concentration of the studied elements, after sequential 
extraction procedure (Sakan et al., 2016). Total concentrations of each element were determined as the sum of concentrations determined in each fraction.
The Kupa River basin, occupies the west-central part of Croatia and is shared by two neighboring countries (Slovenia, Bosnia and Herzegovina). The Kupa itself is a tributary to the Sava River and meets the latter at Sisak after traversing a distance of 294 km. The river basin is one of the most significant water resources in Croatia (Frančišković-Bilinski et al., 2012). 
Vlasina River Basin covers an area of 1061.72 km² and covers the south eastern part of Serbia. The total length of Vlasina River is 65.9 km. The largest part of the geological base of the Vlasina River Basin belongs to the Serbo-Macedonian mass, formed in the Palaeozoic (Carbon-Perm) (Durlević et al., 2019).
Correlation analysis was performed to reveal statistical correlations between MS and 26 elements analyzed by ICP-OES in Kupa sediment samples. Ten of them showed negative correlation (As, B, Ba, Fe, K, Li, Mg, Na, P, S), while other elements showed positive. Chromium showed excellent correlation with MS (0.91) and is element with the highest correlation to MS, what could  indicate its anthropogenic origin. Element with strongest correlation to MS after Cr is vanadium (0.62), followed by Mn (0.52), Al (0.52) and Cd (0.50). All other elements have rather weak correlation with MS, among which highest are those of Sr (0.45), Zn (0.35), Be (0.28), Co (0.27), Pb (0.27) and Ti (0.26). 
Measured MS values in Vlasina samples are mostly very low, with several locations where values are a bit higher; they range from 0.02 x 10-3
to 1.113 x 10-3 SI units. The strongest correlation was observed with Mo (0.43), then with Ag (0.29). Correlations > 0.10 are determined between MS and following elements: Zn (0.17); Cu (0.12); Pb (0.17); Ba (0.13); Mn (0.10); Ti (0.20); V (0.21); In (0.16); Sn (0.16); Tm (0.10); Lu (0.12); Hg (0.16); Bi (0.13); Th (0.15) and U (0.24). Correlation analysis between MS and measured chemical elements has shown that strong correlations do not exist. 
From that it could be concluded that in Vlasina samples there is no significant anthropogenic influence.

AB  - Increasing pollutant levels in surface water are a very important problem in developing countries. In Serbia, the largest rivers are transboundary rivers that cross the border already polluted. Taking this into account, evaluation of the distribution characteristics, ecological risk, and sources of toxic elements in river water and surface sediments in the watercourses of the Vlasina watershed is of great significance for the protection of water resources in Serbia. A total of 17 sediment and 18 water samples were collected and analyzed by Inductively Coupled Plasma—Optical Emission spectrometry (ICP-OES) and Inductively Coupled Plasma—Mass spectrometry (ICP-MS) to determine micro- and macroelements contents. The geo-accumulation index (Igeo) was applied to determine and classify the magnitude of toxic element pollution in this river sediment. The contents of the studied toxic elements were below water and sediment quality guidelines. For studied river water, results of principal component analysis (PCA) indicated the difference in behavior of Cr, Mn, Ni, Cu, and As and V, respectively. Cluster analysis (CA) classified water samples according to As and Cu content. The PCA results revealed that lead in river sediments had different behavior than other elements and can be associated mainly with anthropogenic sources. According to the degree of Igeo, the majority of sediments in the Vlasina region were uncontaminated regarding studied toxic elements. The origin of elements is mostly from natural processes such as soil and rock weathering.

AB  - In this research, the optimized three-step sequential extraction procedure for the fractionation of micro- and macroelements, proposed by Commission of European Communities of reference (BCR) has been applied to the soils from Vlasina region. Element concentrations in the extracts were determined using ICP OES. Magnetic  susceptibility (MS) was measured using magnetic susceptibility meter. The index of geoaccumulation (Igeo) has been applied to assess trace elements distribution and contamination in studied soils. An assessment of toxic element levels in the studied soils is made by comparing the total contents of the extracted elements with the limit values determined by Serbian Regulation. Metal fractionation showed that easily mobile form is 
dominant for lead and manganese. Other elements (Zn, Ni, Cr, Co, As, Cu, Cd, and V), found dominantly in the residual fraction indicate that these elements may be an indicator for natural sources input. Obtained results indicated that the soils from Vlasina region were not contaminated with toxic elements and the origin of elements is mostly from natural processes such as soil and rock weathering.

AB  - In this work, we present the results of element content in river sediments and soil of the Rangárvellir river in southern Iceland as well as in the volcano ash from the Eyjafjallajökull eruption in 2010. Severe natural catastrophes have devastating impact on the environment. We selected the Rangárvellir area located in the vicinity of Mt Hekla, Iceland’s most active volcano, for our study. This study site is ideal to investigate wind and water erosion and sediment transport processes of two main glaciers rivers: the Eystri-Rangá and the Ytri-Rangá and the Hroarslækur River. Sediments of these rivers consist of volcano materials, ash and lava. In order to assess the sediment dynamics, we collected sediment, soil and volcanic ash. The fractioning of the elements was carried out using sequential extractions. The distribution of Si indicates that the sediments originate from the same geochemical basis. Li and partly B exist in the first phase of volcanic ash and river sediments but not in the mobile phases of soils. In the mobile phase of volcanic ash, P was found but it did not exist in the first phase of soil and sediments. These results suggest the different chemical fingerprints in the water sediments and surrounding soil.

AB  - This study investigated the quality of Kupa River sediment using sequential extraction,
ecological risk, and contamination indexes (Risk assessment code, Index of geoaccumulation,
Enrichment factor, Ecological risk factor, Ecological risk index), determination of magnetic
susceptibility of sediments, and statistical methods. The BCR sequential extraction technique
was used for evaluating various element-binding forms. Most of the elements were considered to
be immobile due to the high availability in the residual fraction. Lead was present mainly in the
reducible fraction, while more easily mobile and bioavailable forms were predominant for cadmium
and barium. Sediment samples from the river catchment exhibited low ecological risk. The most
toxic element, Cd, is the main contributor to the total potentially ecological risk. Increased values
of contamination factors have been observed for Zn, Cr, and Ba in some localities. Results of the
comparison of element contents in sediments in a 15-year period (2018 vs. 2003) indicated that the
situation with toxic element content in sediments along Kupa River improved formost of its course.
Unfortunately, on the lower course of the river, the situation has worsened. Using the example of
Kupa River sediments, it was shown that the magnetic susceptibility method is excellent indetecting
increased values of Cr.

AB  - This study reports the contents and sources of chromium, nickel and cobalt, as well as Al, Ca, Mg, K, Fe and Mn in Vojvodina regions Srem and Central Banat area soil samples. Different methods were applied to identify the sources of the studied elements and to classify the latter as geogenic and/or anthropogenic: modified Tessier sequential extraction, calculation ratio of E/Al, XRPD, correlations and cluster analysis. The sampling methodology was according to the GEMAS project.

AB  - Vlasina is a beautiful plateau in the south-east of Serbia. It is a natural protected area, known due to unspoiled nature, clean springs and Vlasina Lake, which is the largest artificial lake in Serbia, located at 1.213 m a.s.l. Vlasina River has its spring under the Vlasina Lake dam and it is about 70 km long tributary of South Morava River. Because of its location in a sparsely inhabited mountain region and because of lack of industrial pollutants in this area, Vlasina is considered to be one of the cleanest Serbian rivers.
We aim to introduce the relatively new, fast and cheap method of magnetic susceptibility (MS) in environmental research in Serbia, in addition to usually used geochemical and mineralogical methods. Until recently MS measurements have not been used for this purpose in the broader region around Serbia, e.g. first such measurements in Croatia were performed by Francišković-Bilinski (2008) on the samples from Kupa River watershed. ´
Measured MS values in Vlasina samples are mostly very low, with several locations where values are a bit higher; they range from 0.02 x 10-3 to 1.113 x 10-3 SI units.
Statistical boxplot analysis of anomalies has shown that 3 extremes (anomalies of higher degree) and 1 outlier (anomaly of lower degree) exist.
Correlation analysis between MS and measured chemical elements has shown that strong correlations do not exist. From that it could be concluded that in Vlasina samples there is no significant anthropogenic influence. In the case of Vlasina strongest correlation was observed with Mo (0.43), then with Ag (0.29). Correlations > 0.10 are determined between MS and following elements: Zn (0.17); Cu (0.12); Pb (0.17); Ba (0.13); Mn (0.10); Ti (0.20); V (0.21); In (0.16); Sn (0.16); Tm (0.10); Lu (0.12); Hg (0.16); Bi (0.13); Th (0.15) and U (0.24). Those correlations support our hypothesis about natural (geogene) origin of those elements from metamorphic rocks,
which prevail in this region.
Q-mode cluster analysis was also performed. It also supports our claim that in Vlasina region there is no significant anthropogenic influence. Cluster 1 from Vlasina is correlated with carbonates, as mean Ca value in this cluster is 8 times higher than in Cluster 2. Cluster 1 contains samples from 4 locations, which are located in the area where carbonate rocks (mainly limestones) are present. On those locations also statistical anomalies of Ca were found using boxplot method. In this carbonate cluster concentrations of majority of heavy metals are lower than in Cluster 2, also MS value is lower, what is due to the fact that in carbonates metal concentrations are naturally lower.

AB  - The need for further research into potentially toxic elements in Serbian rivers led to an
investigation of distributions, sources, and ecological risks in a sample base of sediments from
15 rivers. The analyses were carried out through both experimental and theoretical methods.
Geochemical fractionation of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, As, V, and Zn in sediments was
studied using a sequential extraction procedure. Both a Håkanson risk index (RI) and a Monte Carlo
simulation (MCS) were used in order to estimate ecological risk, applying the probability distribution
of RI values instead of single-point calculations. In order to both further the development of the used
method and include additional processes, software for the simulations was developed instead of
using proprietary solutions. Metal fractionation showed high percentage recoveries of Cd, Cr, Co, Cu,
Fe, Ni, and V in residual fractions. The high content of Pb, Mn, and Zn in mobile fractions might
cause serious environmental concerns. In some localities, Cu and Cd could be problematic elements,
since their mobility was high. An environmental assessment based on the described criteria provided
risk levels varying from low to median (mainly contributed by Cd and Cu).

AB  - The synthesis, spectroscopic characterization, cytotoxic activity and DNA binding evaluation of seven new dinuclear platinum(ii) complexes Pt1-Pt7, with the general formula [{Pt(L)Cl}(2)(-1,5-nphe)](ClO4)(2) (1,5-nphe is 1,5-naphthyridine; while L is two ammines (Pt1) or one bidentate coordinated diamine: ethylenediamine (Pt2), (+/-)-1,2-propylenediamine (Pt3), trans-(+/-)-1,2-diaminocyclohexane (Pt4), 1,3-propylenediamine (Pt5), 2,2-dimethyl-1,3-propylenediamine (Pt6), and 1,3-pentanediamine (Pt7)), were reported. In vitro cytotoxic activity of these complexes was evaluated against three tumor cell lines, murine colon carcinoma (CT26), murine mammary carcinoma (4T1) and murine lung cancer (LLC1) and two normal cell lines, murine mesenchymal stem cells (MSC) and human fibroblast (MRC-5) cells. The results of the MTT assay indicate that all investigated complexes have almost no cytotoxic effects on 4T1 and very low cytotoxicity toward LLC1 cell lines. In contrast to the effects on LLC1 and 4T1 cells, complexes Pt1 and Pt2 had significant cytotoxic activity toward CT26 cells. Complex Pt1 had a much lower IC50 value for activity on CT26 cells compared with cisplatin. In comparison with cisplatin, all dinuclear Pt1-Pt7 complexes showed lower cytotoxicity toward normal MSC and MRC-5 cells. In order to measure the amount of platinum(ii) complexes taken up by the cells, we quantified the cellular platinum content using inductively coupled plasma mass spectrometry (ICP-QMS). Molecular docking studies performed to evaluate the potential binding mode of dinuclear platinum(ii) complexes Pt1-Pt7 and their aqua derivatives W1-W7, respectively, at the double stranded DNA showed that groove spanning and backbone tracking are the most stable binding modes.

AB  - Stepen kontaminacije zemljišta toksičnim elementima definiše se u skladu sa važećim pravilnicima na teritoriji R. Srbije. Neki od definisanih elemenata su uvek toksični za biljke ili ljude (Pb, Cd, As, Hg, V, Sb, Be), a drugi esencijalni, ali u zavisnosti od koncentracija toksični (Cr, Ni, Co, Cu, Zn, Se, Mo...). Međutim, da bi se utvrdio realan stepen rizika, posebno je važno utvrditi sadržaj onih oblika koji su potencijalno mobilni odnosno biodostupni. U ovom radu, utvrđen je sadržaj navedenih toksičnih i potencijalno toksičnih elemenata u onom obliku koji predstavlja opasnost kako za biljke, tako i za ljude, putem lanca ishrane.

abstract = "Stepen kontaminacije zemljišta toksičnim elementima definiše se u skladu sa važećim pravilnicima na teritoriji R. Srbije. Neki od definisanih elemenata su uvek toksični za biljke ili ljude (Pb, Cd, As, Hg, V, Sb, Be), a drugi esencijalni, ali u zavisnosti od koncentracija toksični (Cr, Ni, Co, Cu, Zn, Se, Mo...). Međutim, da bi se utvrdio realan stepen rizika, posebno je važno utvrditi sadržaj onih oblika koji su potencijalno mobilni odnosno biodostupni. U ovom radu, utvrđen je sadržaj navedenih toksičnih i potencijalno toksičnih elemenata u onom obliku koji predstavlja opasnost kako za biljke, tako i za ljude, putem lanca ishrane.

AB  - Potentially harmful trace elements pollution in soils is a worldwide environmental problem that has received increasing attention over the last few decades because of its adverse effects. Metals in soils are present in different chemical forms which affect their ability to transfer. The objective of this body of work was to assessment of contamination degree of elements Cu, Hg, Ni, Cr, Co, Zn, Pb, Cd, As and B in agricultural and grazing soils surrounding the industrial objects, in order to quantify their real influence and real health risk by using investigated soils as croplands. Combination of different methods was applied for estimation of the environmental status of soils and to determine the potential risk of ecological damage. Obtained results indicate that heavy metal contamination should be taken into account during development of management strategies to protect the soil in the Serbia.

AB  - Metals in sediments are present in different chemical forms which affect their ability to transfer. The objective of this body of work was to compare different extraction methods for the bioavailability evaluation of some elements, such as Ba, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Ni, Pb, V and Zn from Serbian river sediments. A bioavailability risk assessment index (BRAI) was used for the quantification of heavy metal bioavailability in the sediments. Actual and potential element availability was assessed by single extractions with mild (CaCl2 and CH3COONH4) and acidic (CH3COOH) extractants and complexing agents (EDTA). Aqua regia extraction was used for the determination of the pseudo-total element content in river sediments. In different single extraction tests, higher extraction of Cd, Cu, Zn and Pb was observed than for the other elements. The results of the single extraction tests revealed that there is a considerable chance of metal leaching from the sediments assessed in this study. When the BRAI was applied, the results showed a high risk of heavy metal bioavailability in Serbian river sediments.
