AB  - Lakes and reservoirs are the main water resources for household, irrigation, and industrial use. Hence, it is necessary to control water pollution and have reliable information on water quality, which refers to its suitability for a particular purpose. The main objective of this study was to evaluate the suitability of water for drinking and irrigation purposes from ten artificial lakes on the territory of the Republic of Serbia. The physicochemical parameters were determined using standard analytical methods, whereas the optical emission spectrometry with inductively coupled plasma, ICP-OES, was used to determine the concentrations of 23 macro-, micro-, and trace elements in water. Health risk indices of drinking water and its suitability for irrigation purposes were evaluated. The results of physicochemical parameters, except for total organic matter, indicated that most samples were within the recommended values. Among analyzed elements, the concentration of Mg was elevated in the water of the lakes Srebrno and Prvonek. The results of health risk assessment clearly showed that there was no acute health risk (HQA < 1), whereas long-term risk (HQL) in the studied lakes was observed with respect to As (lakes Grlište and Srebrno), Mn (lakes Srebrno and Prvonek), Ni (Lake Vrutci), and Sr (Lake Grlište). The irrigation criteria indicated that the water from the examined lakes had satisfactory quality for this purpose, except for residual sodium carbonates (RSC). This criterion indicated low quality or unsuitability of the water in 7 lakes. The main outcomes provided valuable information on the suitability of water from the artificial lakes for intended uses.

AB  - The paper presents the results of research on the content of accessible forms of Ni and Cr in the ranker-type soils that are formed on the serpentinites massifs in Serbia. Soil samples were taken from seven 
different locations across Serbia (Zlatibor mountain, Kopaonik mountain, Miroč, Maljen mountain, 
Bukovi, Suvobor and Bubanj Potok) at the altitude range between 100 and 1700 m. There were 
analyzed 46 soil samples in total. The concentration of accessible forms of Ni and Cr was determined 
by extraction in a solution of DTPA-TEA (pH 7.3, ratio soil and solution = 1:2) by optical emission 
spectroscopy with induced coupled plasma (ICP-OES).
The content of accessible Ni in the all examined soil samples of ranker-type soils varies from 68 - 920 
mg/kg, while the most common results (about 70% of the total number of samples) vary from 200 -
600 mg/kg. The content of accessible Cr in all examined soils varies from 16 - 216 mg/kg. The content 
of both, Ni and Cr significantly exceeds the value limits in soils. 
The results of the analysis of all soil samples of ranker-type soils refer to high concentration of 
accessible Ni and Cr and thus correspond to phytotoxic concentrations.
Given the fact that there are no anthropogenic sources of pollution nearby the investigation locations, 
it can be concluded that such a high concentration of accessible Ni and Cr in the ranker-type soils, that 
were formed on serpentinites massifs under the various pedogenetic conditions, is of geochemical 
origin. The geochemical distribution of Ni and Cr places this type of soil in the group of lithogenic soils.

AB  - Klomazon (IUPAC: 2-(2-hlorobenzil)-4,4-dimetil-1,2-oksazolidin-3-on) je selektivni
herbicid iz grupe izoksazolidinona, koji se na osnovu svojih fizičko-hemijskih karakteristika
može svrstati u grupu pesticida koji predstavljaju potencijalne kontaminante površinskih
voda, dubljih slojeva zemljišta i podzemnih voda.
Glina i organska materija, pre svega huminske kiseline (HA), su glavne sorbujuće
komponente zemljišta. Literaturni podaci ukazuju da u sorpciji klomazona u zemljištu
učestvuje ili organska materija [1-3]ili glina i organska materija [4,5]. S toga je cilj ovog
radabio ispitati potencijal HA i glina izdvojenih iz različitih tipova poljoprivrednog zemljišta
sa područja Republike Srbije (rendzina, černozem i smonica) u sorpciji klomazona, odnosno
odrediti njihov remedijacioni potencijal.
Za proučavanje sorpcionog ponašanja klomazona i određivanje njegovih sorpcionih
konstanti (Kd) za pomenute supstrate je korišćen batch metod [6], zasnovan na ravnotežnoj
raspodeli molekula klomazona u sistemu supstrat/vodena faza. U slučaju HA, sistem se
sastojao od smeše 25 mg supstratai 2,5 mL rastvora određene koncentracije (0,5 – 25
g/mL)klomazona u 0,01 M CaCl2, dok je u slučaju glina sistem sadržao 250 mg gline i 2
mL pomenutih rastvora. Svaka smeša je homogenizovana 24 h radi dostizanja ravnotežne
raspodele ovog jedinjenja između dve faze sistema. Nakon centrifugiranja, vodena faza je
analizirana HPLC-om opremljenim sa PDA detektorom, pri čemu su Kd koeficijenti
klomazona za proučavane supstrate računati kao odnos koncentracije pesticida koja je
sorbovana za supstrat (Cs) i koncentracije jedinjenja koja je zaostala u vodenoj fazi (Ce), u
uslovima ravnotežne raspodele. Adsorpcione izoterme su dobijene primenom Frojndlihove
jednačine na eksperimentalno dobijene rezultate, pri čemu su Frojndlihovi koeficijenti Kf i
n, dobijeni primenom linearne forme Frojdlihove jednačine.
Dobijeni rezultati ukazuju da je sorpcija klomazona mnogo veća za HA nego za gline,
i da opada u sledećem nizu: HA, rendzina (Kd=114,02 mL/g) >HA, smonica
(Kd=97,71 mL/g) >HA, černozem (Kd=91,24 mL/g)>> glina, smonica (Kd=2,29 mL/g)>
glina, černozem (Kd=2,16 mL/g)>glina, rendzina(Kd=1,61 mL/g).
Da je sorpcija klomazona za HA znatno veća nego za gline, ukazuju i vrednosti
Frojndlihovih Kf koeficijenata, koji za pomenute supstrate imaju sledeće vrednosti:
Kf=188,63 (HA, rendzina), Kf=170,61 (HA, smonica), Kf=167,19 (HA, černozem), Kf=1,80
(glina, černozem), Kf=1,10 (glina, rendzina) i Kf=0,98 (glina, smonica). Dobijene vrednosti
Frojndlihovih 1/n koeficijenata ukazuju da su izoterme dobijene za sve analizirane HA Ltpa (0,767, 0,698 i 0,708 za HA poreklom iz zemljišta tipa rendzina, černozem i smonica,
redom), što ukazuje na snažnu sorpciju molekula klomazona za sorpcione centre analiziranih
HA pri nižim koncentracijama pesticida, pri čemu ona opada kako koncentracija jedinjenja
raste. Sa druge strane, izoterme dobijene za gline poreklom iz rendzine i smonice (1/n=1,146
i 1,342, redom) su tzv. S-tipa, što ukazuje na slabiju adsorpciju klomazona za sorpcione
centre supstrata pri nižim koncentracijama pesticida u sistemu, nakon čega se sorpcija
pojačava, da bi pri većim količinama pesticida u sistemu, ona opet počela da se smanjuje
(postepena saturacija sorpcionih centara supstrata). Izoterma dobijena za glinu izdvojenu iz
zemljišta tipa černozem (1/n=1,074) je C-tipa i karakteriše je linearna zavisnost između
sorbovane količine klomazona i količine ovog pesticida koja zaostaje u rastvoru u sistemu
glina/voda.
Prikazani rezultati ukazuju da HA imaju dobar sorpcioni potencijal za klomazon,
odnosno da se mogu koristiti za remedijaciju zemljišta i različitih vodenih sistema
kontaminiranim klomazonom. Dodatne FTIR analize treba da pokažu koje funkcionalne
grupe HA i glina su odgovorne za vezivanje molekula klomazona i samim tim objasne
razlike u veličini sorpcije između različitih HA i glina poreklom iz različitih zemljišta.

zemljišta tipa černozem (1/n=1,074) je C-tipa i karakteriše je linearna zavisnost između
sorbovane količine klomazona i količine ovog pesticida koja zaostaje u rastvoru u sistemu
glina/voda.
Prikazani rezultati ukazuju da HA imaju dobar sorpcioni potencijal za klomazon,
odnosno da se mogu koristiti za remedijaciju zemljišta i različitih vodenih sistema
kontaminiranim klomazonom. Dodatne FTIR analize treba da pokažu koje funkcionalne
grupe HA i glina su odgovorne za vezivanje molekula klomazona i samim tim objasne
razlike u veličini sorpcije između različitih HA i glina poreklom iz različitih zemljišta.",

AB  - Kinetic studies are important for understanding the parameters and processes involved in the sorption of pesticides to soil. Considering the agricultural and environmental relevance of clomazone, its sorption kinetics was studied in four agricultural soils (Regosol, Planosol, Chernozem and Vertisol) at two concentrations (0.5 and 15 mg L−1). Different kinetic models were applied to the experimental data. The pseudo-second-order model described the data much better than the hyperbolic and pseudo-first-order models, and the kinetic rate constants indicated concentration-dependent clomazone sorption kinetics. The application of the two-site nonequilibrium model (TSNE) revealed a more time-dependent sorption of the lower clomazone concentration than that of the higher clomazone concentration, and the greatest concentration impact occurred in Regosol. Elovich and intraparticle diffusion models predicted more intensive sorption during the slower second phase and that sorption kinetics is governed more by mass transfer across the boundary layer than by a intraparticle diffusion process at higher clomazone concentration. Intraparticle diffusion is the rate-controlling process in Regosol at lower concentration, while this process and the boundary layer control the sorption kinetics in other soils. Significant correlations between some kinetic parameters and soil properties indicate an impact of the soil texture on the clomazone sorption mechanism, which must be considered in assessing the clomazone leaching behavior.

AB  - UVOD i CILjEVI: Sadržaja organske materije (OM) u zemljištu je bitan faktor pri odabiru
loznih podloga i sorti vinove loze pošto značajno utiče na vegetativni porast i prinos, koji su u
proizvodnji vina kontrolisani, tako da je važno precizno odrediti sadržaj OM pri podizanju i
eksploataciji zasada vinove loze. Cilj ovog istraživanja jeste precizno i prostorno predstavljanje
sadržaja OM u rendzinama na području Krnjevačkog vinogorja. Rendzina je jedno od najpogodnijih
vinogradarskih zemljišta kod nas. Prema zvaničnom sistemu klasifikacije zemljišta Srbije,
rendzina je tip zemljišta sa A – AC – C – R profilom, razvijen na matičnoj steni koja sadrži
više od 20% krečnjačkog materijala (osim zemljišta sa A – R profilom na tvrdom čistom
krečnjaku ili dolomitu). U Svetskoj referentnoj bazi za zemljišne resurse (WRB) rendzine
odgovaraju uglavnom renzičnim leptosolima (Rendzic Leptosols) ili faozemima (Phaeozems).
MATERIJAL i METOD: Krnjevačko vinogorje je deo Šumadijskog vinogradarskog rejona, nalazi
se na brežuljkastim padinama i kosama zapadno od Velike Morave, a severno od Smederevske
Palanke i Velike Plane, prostire se na površini od 11188,22 ha. Istraživanje je sprovedeno u
vinogradu Podruma Radovanović (44°25ʹ57,60ʺ SGŠ; 21°02ʹ40,34ʺ IGD i 44°25ʹ 41,33ʺ SGŠ;
21°02ʹ51,29ʺ IGD), na pet parcela zasađenih različitim sortama vinove loze gde je otvoreno i
opisano 15 pedoloških profila. Uzorci u narušenom stanju su uzeti iz svih genetskih horizonata
od površine do matične stene. Sadržaj organskog ugljenika (OC) određen je dihromatnom metodom
u 54 uzorka zemljišta, a sadržaj OM je proračunat prema formuli OM = OC x 1,72. Prostorni
prikaz sadržaja OM u ispitivanim zemljištima urađen je korišćenjem programa ArcGis 10.0.
REZULTATI i ZAKLjUČCI: Na ispitivanom lokalitetu identifikovana su tri varijeteta
rendzine: karbonatana rendzina, rendzina u ogajnjačavanju i izlužena rendzina. Sadržaj OM u
humusnom horizontu rendzina varirao je u opsegu od 1,18% do 4,17%, sa prosečno vrednošću od
2,55 ± 0,56%. Zemljišta ispitivanog područja su slabo i srednje humusna, što je povoljno s
obzirom na to da se najbolji vinogradraski i vinarski rezultati dobijaju na srednje plodnim
zemljištima koja imaju neka pedološka ograničenja. Idealno vinogradarsko zemljište sadrži 2–
4% OM. Sadržaj OM se pravilno smanjivao po dubini profila, tako da je u C horizontu iznosio od
0,67% do 1,04%, a prosečna vrednost je bila 0,97 ± 0,21%. Relativno visok sadržaj OM u C
horizontu je posledica dubokog prodiranja korenovog sistema vinove loze. Na tematskoj karti koja
prostorno prikazuje sadržaj OM u površinskom horizontu može se uočiti da je najviši sadržaj
OM u zoni gde se vinograd graniči sa šumom, što dovodi do zaključka da je u ovom delu izraženije
nakupljanje OM (u odnosu na preostalu ispitivanu površinu), verovatno kao posledica prirodnog
unošenja organskih ostataka šumske vegetacije. Na osnovu rezultat studije može se zaključiti da
su ispitivana zemljišta prema sadržaju OM pogodna za uzgoj vinove loze. Prostorni prikaz
sadržaja OM omogućava izdvajanje određenih površina za dalje analize kvaliteta grožđa i vina.

AB  - Universal Soil Loss Equation (USLE) is the most applied model for soil erosion assessment. It
takes into consideration five soil erosion factors among which soil erodibilty factor (K) is a
measure of inheritant reistance of soils to erosion. In the formulation of USLE model, K–factor
was determined experimentally, and then the authors created USLE nomograph to facilitate the
work, and in the next step, created the equation for faster K–factor determination. This paper
aims to compare K–factor obtained by USLE nomograph and USLE equation. A total number of
108 soil samples have been collected in Western Serbia. For the determination of K–values,
particle size distribution and soil organic matter were analyzed in the laboratory, whereas soil
permeability and soil structure were assessed according to the USLE document procedure. The
results have been compared using basic statistics. The average K–values obtained by nomograph
and equation differ for almost 15%. There is statistically significant correlation between the two
methods, but coefficient of determination amounts to 0.5802, which indicates pretty high
deviation. Root Mean Square Error (RMSE) amounts to 0.008, which is quite high, whereas
index of agreement amounts to 0.93, representing good agreement. These results are ambiguous.
We think that 15% of absolute error is a threshold value between single samples, which occur in
only 56% of the cases. Therefore, the obtained results indicate the gaps in the determination of
K–factor and could contribute to further improvment of soil erodibilty determination and
consequently, soil erosion assessment.

AB  - Universal Soil Loss Equation (USLE) is the most applied model for soil erosion assessment. It takes into consideration five soil erosion factors: rainfall erosivity, topographic factor, vegetation cover, applied conservation practices, and soil erodibility. Soil erodibilty factor (K-factor) is a measure of inheritant reistance of soils to erosion. In the formulation of USLE model, K-factor was determined experimentally. Experimental determinations are costly and time- consuming, so the authors have encouraged scientists to utilise USLE nomograph or derived equations. This paper aims to compare USLE nomograph and soil erodibility equation which was derived from nomograph by the same authors. A total number of 108 soil samples have been collected on agricultural land of Western Serbia. For the determination of K-values, particle size distribution and soil organic matter content were determined in the laboratory, whereas soil permeability and soil structure were assessed according to the nomograph. The results have been compared using basic statistics. The average K-values obtained by nomograph and derived equation are 0.034±0.010 and 0.029±0.012, which is 14.7% difference. Coefficient of determination (R2) amounts to 0.5802, which indicates deviation of 23.9%, although there is statistically significant correlation between two methods. Root Mean Square Error (RMSE) is 0.008, which is 23–27% difference. The RMSE is not low, whereas index of agreement amounts to 0.93, which represent good agreement, and also there is significant correlation. These results are ambiguous. We think that 15% of absolute error is a threshold value for good correlation, which occur on only 56% of samples. K-factor is an important part of various soil erosion models and it is of high importance to determine it in the best manner. Therefore, the obtained results indicate the gaps in the determination of K-factor and could contribute to further improvment of soil erodibilty determination and consequently, soil erosion assessment.

AB  - National soil classification system (NSCS) used in Serbia is based on the principles of genetic classification. It is utilizes the concept of genetic soil horizons. The world reference base (WRB) for soil resources is based on soil properties defined in terms of diagnostic horizons, diagnostic properties, and diagnostic materials, which to the greatest extent possible should be measurable and observable in the field. The difference between genetic vs. diagnostic horizons creates an obstacle in correlation of soil types from NSCS with reference soil groups (RSG's) of WRB for soil resources, whereas the advantage in this work is that most of the soil names of national system correlate to the revised legend of the Soil Map of the World which is an forerunner of WRB for soil resources.
This work aims to compare Ranker soil type of NSCS with corresponding RSG from WRB for soil resources, namely with Leptosols, as they have been reported in Serbia and abroad, as an appropriate reference soil group. The comparison was conducted on the base of qualitative and semi–quantitative information collected from the literature and experience of the authors – theretical approach. It was conducted in two ways: a) Leptosols vs. Rankers, meaning which Leptosols of WRB for soil resources are Rankers in NSCS, and b) Rankers vs. Leptosols, meaning which Rankers of NSCS are Leptosols in WRB.
The conclusion of our work is that Leptosols RSG can correspond to Rankers in NSCS, but some WRB Leptosols are also Lithosols, Technosols, soils of Subaquatic soil order, Eugleys, Humogleys, Peat Soils, Rendzinas, Kalkomelanosols, Eutric and Dystric Cambisols, whereas Gypsiric Leptosols can not be classified according to NSCS. Observing in different direction, the results show that Ranker Soils could be also part of some other RSG with Leptic principal qualifier, such as Andosols, Phaeozems, Umbrisols, Cambisols, and Regosols. This work represents a small contribution to soil science in Serbia as WRB is comprehensive classification system that enables accommodation of NSCS's for communication at the international level.

AB  - Soil structure pertains to the natural organization of soil particles into various forms as a result of pedogenic processes. On one hand, it is formed in interaction of physical, chemical, mineralogical, and biological factors, whereas on the other hand it affects them. Soil structure can differ in grade of development, size and type of aggregates, and their stability to mechanical pressure and water, which is often soil-horizon or soil-type dependent. This paper aims to analyze the structure of Calcomelanosols of mountain Rtanj, Serbia, as that is the most widespread soil type in this area. Calcomelanosols are soils from the national classification system that often correspond to Rendzic Leptosols in the World Reference Base (WRB) for soil resources. Soil structure is analyzed in terms of soil dry aggregate size distribution (ASD) and soil aggregate stability to water (WAS), and related soil structure indices, as they are essential parameters in understanding the structural state of the soil. Eight soil profiles have been excavated, described and sampled in the field. Soil horizon sequence of all profiles was A – R, with humus-accumulative horizon overlying calcareous bedrock. Six profiles of Calcomelanosols correspond to Rendzic Leptosols of WRB, whereas other two profiles correspond to Leptic Rendzic Phaeozems and Leptic Chernic Rendzic Phaeozems. Basic physical and chemical soil properties were determined. Both ASD and WAS were determined by Savinov's method. The following soil structure indices were calculated: dry mean weight diameter (dMWD), wet mean weight diameter (wMWD), dry geometric mean diameter (dGMD), wet geometric mean diameter (wGMD) and structural stability index (SI). The results indicate favorable structure of the examined Calcomelanosols. The content of agronomically most valuable aggregates (0.25–10 mm) in all soil profiles exceeds 80% (90.5±3.6% on average). Among these aggregates, very fine, fine and medium size aggregates dominate. Dry MWD showed values ranging from 3.0–5.5 mm, whereas wMWD ranges from 1.9– 3.3 mm. The wMWD and dMWD ratio is an indicator of the stability of structural aggregates. A small change in the aggregate size after wet sieving was found, 0.7±0.1 mm on average. In all examined soil profiles SI is higher than 19% (32.9±7.1% on average), which indicates an extremely stable structure, without risk of the structural degradation of soil. Correlation analysis showed a significant positive relationship between the content of agronomically valuable fractions (0.25–10 mm) and the following soil parameters: soil organic matter (SOM), pH, and base saturation (%V). Also, there is a strong positive correlation between SI and pH, and SI with %V. Other calculated structural indices show a strong negative correlation with SOM, pH and %V. All analyzed soil profiles have favorable soil structure and water stable soil aggregates with low risk of soil structure degradation. This is of extreme importance because Calcomelanosols cover the steep and
sloping land which is naturally more prone to soil water erosion and soil degradation.

AB  - Environmental problems related to the application of herbicides are causing a concern due to their increasing presence in soil, groundwater and surface water. Numerous methods have been developed in order to reduce herbicide mobility and protect natural water resources. The results presented in this paper show the interaction of herbicide S- metolachlor with inorganic and organically modified montmorillonite from Bogovina (Boljevac municipality, Serbia). Clay sample from Bogovina represents Ca-Na montmorillonite with a small amount of quartz, cristobalite and carbonate minerals. Organic montmorillonites were obtained after modification with different concentrations of organic complex (HDTMA and PTMA), whereas inorganic modification was performed with 1M NaCl solution. The interaction between minerals and herbicide was monitored using infrared spectroscopy. IR bands observed in the inorganic modified montmorillonite (Na-montmorillonite) are typical for smectites with a high Al content in the octahedron position.
The intercalation of HDTMA+ cations into the interlayer space produces redshift of the IR bands that originate from the vibrations of the adsorbed water, as a consequence of the hydrogen bond strength reduction in HDTMA-montmorillonite. Also, the intensity of these bands decreases significantly with the increasing concentration of HDTMA+ cation. All these changes are related to the decreasing of the water content in the interlayer space by increasing the content of HDTMA. The occurrence of the stretching CH2 vibrations is generally the main difference in the spectrum of HDTMA modified montmorillonite in comparison with the spectrum of inorganically modified montmorillonite. The wavenumber, intensity and width of these bands are sensitive to conformation in hydrocarbon chains. After the organic modification of the montmorillonite with the PTMA complex, stretching vibrations of the phenyl ring occurred.
Analysis of FTIR spectroscopy data showed that the hydrogen bond is one of the most important mechanisms that occur between Na-montmorillonite and S-metolachlor. Comparing the FTIR spectra of herbicides before and after the sorption, it can be concluded that the carbonyl group participate in the binding process. Sorption of S- metolachlor on HDTMA-montmorillonites causes the redshift of the C=O absorption band. Shifting to lower wavenumbers and joining with the deformation vibration band of water indicates that the C=O group participated in the formation of a bond with the montmorillonite. Sorption of S-metolachlor molecules on PTMA-montmorillonite takes place through the interaction between the aromatic benzene ring of S-metolachlor and the aromatic benzene ring of the organic complex (π-π bonds). Also, the formation of a hydrogen bond occurs between the molecules of S-metolachlor and the molecules of water that are in the interlayer space and/or oxygen on the surface of the tetrahedral sheet of the montmorillonite.

AB  - UVOD i CILjEVI: U okviru klasifikacije zemljišta u genetskim klasifikacionim sistemima
se nekada javljaju dileme kome tipu zemljišta pripadaju neke zemljišne jedinice, jer ne postoje
direktno utvrđeni kvantitativni pokazatelji koji razgraničavaju pojedine zemljišne jedinice ili
pojedine pedogenetske procese, i utvrđuju hijerarhiju među njima za potrebe klasifikacije. U
okviru šire studije, u podnožju krečnjačkog masiva planine Vukan, na potesu Veliko polje,
otvoreno je 42 zemljišna profila. Karbonatna skeletna zemljišta na jedrim krečnjacima sa
izraženim humusno-akumulativnim horizontom su identifikovana na oko 40% područja, odnosno
na 15 otvorenih profila.
MATERIJAL i METOD: Istraživanja su obuhvatala otvaranje profila zemljišta do 90 cm
dubine, odnosno do dubine matične stene, detaljan opis zemljišta na terenu, kao i uzimanje uzoraka
zemljišta u narušenom i nenarušenom stanju za laboratorisjke analize, kao i klasifikaciju
zemljišta prema domaćem i međunarodnom sistemu (WRB) klasifikacije.
REZULTATI i ZAKLjUČCI: Zemljišta su klasifikovana kao koluvijalni kalkomelanosoli.
Koluvijalni kalkomelanosoli su identifikovani na nadmorskoj visini od svega 185–210 m, što je
neuobičajeno za ovaj tip zemljišta. Iz istog razloga i njegove ostale fizičko-hemijske osobine
odstupaju od do sada opisanih koluvijalnih kalkomelanosola. Teren pod kalkomelanosolima se
koristi kao ekstenzivni pašnjak, dominantan nagib terena je 2–5%, a skeletnost površine iznosi
10–80% u zavisnosti od profila. Građa većine ispitivanih profila je A – R. Boja humusnoakumulativnog horizonta je veoma tamna braon i veoma tamna braon siva, nešto svetlija od
tipičnih crnica. Koluvijalni kalkomelanosoli se odlikuju dubinom 40–70 cm, a sadržaj skeleta
se povećava sa dubinom. Veličina skeleta je 2–200 mm, a oblik je nepravilan – uglast. Struktura
zemljišta je umereno izražena, dominantna veličina zrnastih agregata je 1–5 mm. Veoma visok
sadržaj kalcijum-karbonata u supstratu, 90–99% u 12 profila ukazuje na jedre krečnjake. Skelet je
po dubini zemljišnog profila i karbonatan i beskarbonatan, što ukazuje na koluvijalne procese u
prošlosti. Intenzivno hemijsko raspadanje ovog skeleta je dovelo čak i do pojave
pseudomicelarnog potpovršinskog horizonta koji se nalazi iznad matične stene u dva profila,
kao i do pojave karbonatnosti zemljišne mase u horizontima, što nije tipično za kalkomelanosole.
Zemljišta nisu klasifikovana kao rendzine, jer postojeća nacionalna klasifikacija ne prepoznaje
rendzine na jedrim krečnjacima, već samo na mekim krečnjacima. Takođe, zemljišta nisu
klasifikovana ni kao karbonatni koluvijumi jer nisu nastala taloženjem podukata raspadanja
mekih karbonatnih stena. Zemljišta su dakle prema nacionalnoj klasifikaciji koluvijlni

abstract = "UVOD i CILjEVI: U okviru klasifikacije zemljišta u genetskim klasifikacionim sistemima
se nekada javljaju dileme kome tipu zemljišta pripadaju neke zemljišne jedinice, jer ne postoje
direktno utvrđeni kvantitativni pokazatelji koji razgraničavaju pojedine zemljišne jedinice ili
pojedine pedogenetske procese, i utvrđuju hijerarhiju među njima za potrebe klasifikacije. U
okviru šire studije, u podnožju krečnjačkog masiva planine Vukan, na potesu Veliko polje,
otvoreno je 42 zemljišna profila. Karbonatna skeletna zemljišta na jedrim krečnjacima sa
izraženim humusno-akumulativnim horizontom su identifikovana na oko 40% područja, odnosno
na 15 otvorenih profila.
MATERIJAL i METOD: Istraživanja su obuhvatala otvaranje profila zemljišta do 90 cm
dubine, odnosno do dubine matične stene, detaljan opis zemljišta na terenu, kao i uzimanje uzoraka
zemljišta u narušenom i nenarušenom stanju za laboratorisjke analize, kao i klasifikaciju
zemljišta prema domaćem i međunarodnom sistemu (WRB) klasifikacije.
REZULTATI i ZAKLjUČCI: Zemljišta su klasifikovana kao koluvijalni kalkomelanosoli.
Koluvijalni kalkomelanosoli su identifikovani na nadmorskoj visini od svega 185–210 m, što je
neuobičajeno za ovaj tip zemljišta. Iz istog razloga i njegove ostale fizičko-hemijske osobine
odstupaju od do sada opisanih koluvijalnih kalkomelanosola. Teren pod kalkomelanosolima se
koristi kao ekstenzivni pašnjak, dominantan nagib terena je 2–5%, a skeletnost površine iznosi
10–80% u zavisnosti od profila. Građa većine ispitivanih profila je A – R. Boja humusnoakumulativnog horizonta je veoma tamna braon i veoma tamna braon siva, nešto svetlija od
tipičnih crnica. Koluvijalni kalkomelanosoli se odlikuju dubinom 40–70 cm, a sadržaj skeleta
se povećava sa dubinom. Veličina skeleta je 2–200 mm, a oblik je nepravilan – uglast. Struktura
zemljišta je umereno izražena, dominantna veličina zrnastih agregata je 1–5 mm. Veoma visok
sadržaj kalcijum-karbonata u supstratu, 90–99% u 12 profila ukazuje na jedre krečnjake. Skelet je
po dubini zemljišnog profila i karbonatan i beskarbonatan, što ukazuje na koluvijalne procese u
prošlosti. Intenzivno hemijsko raspadanje ovog skeleta je dovelo čak i do pojave
pseudomicelarnog potpovršinskog horizonta koji se nalazi iznad matične stene u dva profila,
kao i do pojave karbonatnosti zemljišne mase u horizontima, što nije tipično za kalkomelanosole.
Zemljišta nisu klasifikovana kao rendzine, jer postojeća nacionalna klasifikacija ne prepoznaje
rendzine na jedrim krečnjacima, već samo na mekim krečnjacima. Takođe, zemljišta nisu
klasifikovana ni kao karbonatni koluvijumi jer nisu nastala taloženjem podukata raspadanja
mekih karbonatnih stena. Zemljišta su dakle prema nacionalnoj klasifikaciji koluvijlni
kalkomelanosoli, organo-mineralni, i u odnosu na tipične kalkomelanosole odlikuju se većom
dubinom soluma, prisutnošću kalcijum-karbonata u zemljišnoj masi, skeletnošću, krupnijim
strukturnim agregatima, i dosta nižim sadržajem humusa. Većina ispitivanih profila pripada
Leptic Rendzic Phaeozems (Colluvic) prema WRB sistemu klasifikacije.",

AB  - The adsorption behaviour of the herbicide clomazone on inorganic and organically modified montmorillonite from the Bogovina deposit in Serbia was investigated. Montmorillonite was modified first with NaCl and then with organic complexes such as hexadecyltrimethylammonium bromide (HDTMA) and phenyltrimethylammonium chloride (PTMA). Changes in the surface properties and morphology of the montmorillonite before and after the modification with various concentrations of organic complexes were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Adsorption of clomazone on all examined samples was investigated using the batch adsorption method. Montmorillonite modified with HDTMA-bromide displayed greater uptake of the clomazone compared to the PTMA-montmorillonite, and both organically modified montmorillonites displayed greater uptake of the herbicide compared to the inorganic montmorillonite. Comparing the Freundlich coefficient and maximum adsorbed clomazone quantity values obtained by Langmuir model, the levels of adsorption of clomazone decreased in the following order: HDTMA-montmorillonite with 1.00 cation-exchange capacity (CEC) saturation > HDTMA-montmorillonite with 0.75 CEC saturation > PTMA-montmorillonite with 1.00 CEC saturation > PTMA-montmorillonite with 0.75 CEC saturation > HDTMA-montmorillonite with 0.50 CEC saturation > HDTMA-montmorillonite with 0.25 CEC saturation > PTMA-montmorillonite with 0.50 CEC saturation > PTMA-montmorillonite with 0.25 CEC saturation > Na-montmorillonite > raw sample. The type and content of an organic cation plays an important role in the behaviour of clomazone in a solid/liquid system. It is concluded that organically modified montmorillonite from Bogovina might be used as an effective adsorbent for clomazone.

AB  - Studies of adsorption and desorption of pesticides by soils are important for understanding and predicting their fate and transmission in the environment. Considering the agricultural and environmental relevance of clomazone, its sorption-desorption behaviour was studied in two widespread Serbian agricultural soil types named Regosol and Chernozem. Both phenomena are well-described by the Freundlich equation, which shows that clomazone is generally sorbed more to organic matter than to the mineral soil fractions. Chernozem, a soil containing more of both organic matter and clay, was found to bind more, and desorb less herbicide, than Regosol. Higher desorption hysteresis obtained for Chernozem could be attributed to its larger number of high-energy sorption sites, compared to Regosol. In both soils, the hysteresis effect increases with the rise of initial clomazone concentration in the soil-water system, while the percentage of desorbed amount during successive desorption cycles decreases. The presented adsorption-desorption study shows that soil composition plays an important role in clomazone behaviour and fate in the environment, and a significantly reduced probability of contamination of both the deeper soil layers and groundwater may be expected when this herbicide is found in humus-rich soils.

AB  - Two samples collected from the phosphogypsum deposits of the chemical products industry Elixir Prahovo (Serbia) were subjected to a recrystallization experiment performed over several repeated cycles. In these tests, phosphogypsum was separated into recrystallized (purified) gypsum, insoluble residue and supernatant. Both raw phosphogypsum and recrystallized gypsum were examined using inductively coupled plasma optical emission spectrometry, X-ray diffraction and scanning electron microscopy with energy-dispersive spectrometry. The activity concentrations of (238)u, (235)u, Ra-226, Pb-210,Th- 232 and 40 K were investigated using gamma-ray spectrometry. Based on the activity concentration results, a number of radiometric parameters were calculated for the original and recrystallized phosphogypsum (i.e. radium equivalent activity, y indices for construction materials, a index and external and internal hazard indices). Raw phosphogypsum samples showed greater mean activity concentration levels of U-238 and Ra-226 than the international recommended limits, while the recrystallized gypsum demonstrated notably lower activity concentrations for these two isotopes. The activity concentration of Ra-226 in recrystallized gypsum is similar to 6 times lower than in raw phosphogypsum. Therefore, recrystallized gypsum does not present a radiation hazard when used as a building material, while raw phosphogypsum meets the requirements only for road construction materials.

AB  - In this study, the chemical and phase composition of two samples of phosphogypsum from the waste dumps of the Industry of Chemical Products "Elixir - Prahovo" (Serbia) were examined, as well as the possibility of recrystallization of gypsum from an aqueous suspension of phosphogypsum. 'the negative effect of higher temperatures on the solubility of calcium sulfate (13.08 mmol/dm(3) at 95 degrees C vs. 15.43 mmol/dm(3) at 40 degrees C) was utilized. In several repeated cycles, calcium sulfate component was progressively dissolved in water at room temperature and then precipitated at 100 degrees C, using the same liquid phase throughout the experiment. Therefore, phosphogypsum was separated into recrystallized (purified) gypsum, insoluble residue and supernatant, and the mass balance for the experiment was calculated. Elemental, XRD and SEM-EDS analyses were performed on raw phosphogypsum, purified gypsum and insoluble residue. The whiteness of raw phosphogypsum and purified gypsum were determined and compared. The main objective of the study was to investigate the nature of insoluble impurities, in order to define and optimize the methods for their removal during a potential industrial processing of phosphogypsum.

AB  - This study focuses on the mineralogical characterization of four raw clay samples from Dobrodo deposit, Serbia. Several analytical methods were applied to determine the chemical and mineralogical composition, morphology and physical properties (colour, plasticity, specific surface area, particle size and cation-exchange capacity) of the clay samples. Kaolinite, smectite and illite are the predominant phases in all of the samples studied that contain between 60.2 and 87.1 wt.% of clay. Quartz, feldspars, paragonite and Ti- and Fe-bearing phases were also identified. The relatively high SiO2/Al2O3 mass ratio indicates abundant quartz. The cation-exchange capacity of the samples varied between low and moderately charged clay minerals (12-52 mmol 100 g(-1)) with specific surface area values ranging from 94 to 410 m(2) g(-1). The plasticity index values (11-23%) suggest low to moderate plasticity. Preliminary results show that most of the raw clay from Dobrodo deposit might be suitable for use in ceramic applications.

AB  - This study of environmental radioactivity was carried out in the soils of an urban area. Naturally occurring gamma-emitting radionuclides and man-made Cs-137 were found in the soil profiles collected from four parks in the central Belgrade city area and the soil layer was examined every 10 cm and to a depth of 50 cm. Radioisotope activity concentrations (Bq kg(-1)) in the samples of urban soil using the gamma-ray spectrometry method were in the range of 14-46 for U-238, 33-50 for Ra-226, 29-63 for Pb-210, 1.2-3.4 for U-235, 28-50 for Th-232, 424-576 for K-40 and 0.7-35.8 for Cs-137. Some of the basic physicochemical soil properties (pH, organic matter content, calcium-carbonate content, particle size distribution) were determined to investigate the impact on the vertical distribution of radionuclides. The results of this investigation showed that variations of activity concentration ratios of radionuclides that belong to the same (U-238/Ra-226) or different radioactive series (Th-232/Ra-226; U-235/U-238), including Pb-210/Cs-137 ratios could well be explained by the properties of the soil. Alkaline pH reaction, the accumulation of organic matter in the uppermost and of carbonates in the deepest layers of urban soil had an effect on U-238/Ra-226, and Pb-210/Cs-137 activity concentration ratio values, while Th-232/Ra-226 and partially U-235/U-238 ratios were associated with the particle sizes vertical distribution. A study of radionuclides in the samples of leaves of two deciduous tree species common for these parks was also conducted and Pb-210 and K-40 were found concentrated in leaves rather than other investigated radionuclides.

AB  - This study aims at analysing physical, chemical and microbiological properties, and content of macro- and microelements in the water from the Požarevac city public water supply system. Analysis shows an increased content of Ca in drinking water, as a result of the position of Požarevac on the sediments of river terrace of accumulative character of t1 type, predominantly consisting of quartzite. The water from the public water supply is alkaline ('calcic', 'bicarbonate water') and very hard, due to the increased Ca content. Beside Ca, potassium and aluminium exceed the maximum contaminant level, while Pb and Cd are at the very limit. Calculated data show that there are no short-term health risks regarding elements exceeding allowed concentrations found in the public water supply system. Data analysis regarding long-term health risks shows that Cd present in drinking water poses the only relevant threat to human health. Cancer risk is present in 202 out of 1000 inhabitants using this water.

AB  - The results presented in this paper show an impact of the concentration of the aromatic organic cation on the adsorption of acetochlor on the surface of the organic-modified montmorillonite. Natural montmorillonite from Bogovina (Boljevac municipality, Serbia) was used for organic modification in this experiment. Cation exchange capacity of this montmorillonite (86mmol 100g(-1) of clay) was determined using the methylene blue method. In pretreatment, montmorillonite was modified with NaCl. For the purpose of organic modification, three different concentrations of phenyltrimethylammonium chloride (PTMA) have been selected, based on calculated CEC value: 43mmol 100g(-1) of clay (0.5 CEC), 86mmol 100g(-1) of clay (1 CEC) and 129mmol 100g(-1) of clay (1.5 CEC). The changes in the properties of the inorganic and organic modified montmorillonite were examined using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and batch equilibrium method. Freundlich coefficients show higher uptake of the herbicide by montmorillonite modified with PTMA, compared to inorganic-modified montmorillonite. The results also indicate the influence of the organic cation concentration on the adsorption of the selected herbicide.

AB  - Efficiency of inorganic and organic modified montmorillonites from Bogovina for sorption of the S-metolachlor and clomazone was determined using batch adsorption method. Montmorillonite samples were pretreated with NaCl solution and then with different concentrations of organic complexes. Adsorption isotherms were measured by treatment of the samples with different concentrations of herbicide. Detailed mineralogical characterization of samples was performed using the X-ray diffraction method. Results of interaction between organic complexes and herbicides were obtained using X-ray diffraction, optical, thermal and spectroscopic analysis. Based on the results obtained using X-ray diffraction, it was concluded that all examined organic complexes and herbicides intercalated into interlayer space of montmorillonite. Montmorillonites modified with HDTMA complex exhibited monolayer, bilayer and pseudotrilayer arrangement of HDTMA+ cations in interlayer space, depending on degree of saturation. It has been found that the HDTMA+ cations are forming the partition phase for the herbicide on the surface of the montmorillonite. On the other hand, montmorillonite modified with PTMA complex exhibited monolayer arrangement of cations on the surface of montmorillonite in such a way that the cations act as pillars in interlayer space. The molecules of herbicides in this case were adsorbed on the surface of the montmorillonite. Which functional groups were involved in bonding processes between montmorillonite, organic complex and herbicide best describes infrared spectroscopy. High sorption of examined herbicides on some organic modified montmorillonites creates an opportunity for application of these substrates as potentially useful material for removal of S-metolachlor and clomazone from the environment.
AB  - fikasnost prilikom sorpcije S-metolahlora i klomazona od strane neorganskih i organski modifikovanih montmorionita sa lokaliteta Bogovina odreĎena je metodom bach adsorpcije. Uzorci montmorionita su tretirani prvo rastvorom NaCl a zatim i različitim koncentracijama organskih kompleksa. Adsorpcione izoterme su dobijene tretiranjem uzoraka različitim koncentracijama herbicida. Detaljna mineraloška karakterizacija uzoraka uraĎena je metodom rendgenske difrakcije. Rezultati interakcije montmorionita sa organskim kompleksima i herbicidima dobijeni su primenom rendgenskih, optičkih, termičkih i spektroskopskih metoda. Na osnovu rezultata rendgenskih ispitivanja uzoraka, utvrĎeno je prisustvo organskih kompleksa i herbicida u meĎuslojnom prostoru montmorionita. Montmorioniti modifikovani sa HDTMA kompleksom pokazivali su jednoslojnu, dvoslojnu i pseudotroslojnu orijentaciju HDTMA+ katjona u meĎuslojnom prostoru. UtvrĎeno je da HDTMA+ katjoni formiraju particionu fazu na površini montmorionita, na kojoj dolazi do sorpcije molekula herbicida.

abstract = "Efficiency of inorganic and organic modified montmorillonites from Bogovina for sorption of the S-metolachlor and clomazone was determined using batch adsorption method. Montmorillonite samples were pretreated with NaCl solution and then with different concentrations of organic complexes. Adsorption isotherms were measured by treatment of the samples with different concentrations of herbicide. Detailed mineralogical characterization of samples was performed using the X-ray diffraction method. Results of interaction between organic complexes and herbicides were obtained using X-ray diffraction, optical, thermal and spectroscopic analysis. Based on the results obtained using X-ray diffraction, it was concluded that all examined organic complexes and herbicides intercalated into interlayer space of montmorillonite. Montmorillonites modified with HDTMA complex exhibited monolayer, bilayer and pseudotrilayer arrangement of HDTMA+ cations in interlayer space, depending on degree of saturation. It has been found that the HDTMA+ cations are forming the partition phase for the herbicide on the surface of the montmorillonite. On the other hand, montmorillonite modified with PTMA complex exhibited monolayer arrangement of cations on the surface of montmorillonite in such a way that the cations act as pillars in interlayer space. The molecules of herbicides in this case were adsorbed on the surface of the montmorillonite. Which functional groups were involved in bonding processes between montmorillonite, organic complex and herbicide best describes infrared spectroscopy. High sorption of examined herbicides on some organic modified montmorillonites creates an opportunity for application of these substrates as potentially useful material for removal of S-metolachlor and clomazone from the environment., fikasnost prilikom sorpcije S-metolahlora i klomazona od strane neorganskih i organski modifikovanih montmorionita sa lokaliteta Bogovina odreĎena je metodom bach adsorpcije. Uzorci montmorionita su tretirani prvo rastvorom NaCl a zatim i različitim koncentracijama organskih kompleksa. Adsorpcione izoterme su dobijene tretiranjem uzoraka različitim koncentracijama herbicida. Detaljna mineraloška karakterizacija uzoraka uraĎena je metodom rendgenske difrakcije. Rezultati interakcije montmorionita sa organskim kompleksima i herbicidima dobijeni su primenom rendgenskih, optičkih, termičkih i spektroskopskih metoda. Na osnovu rezultata rendgenskih ispitivanja uzoraka, utvrĎeno je prisustvo organskih kompleksa i herbicida u meĎuslojnom prostoru montmorionita. Montmorioniti modifikovani sa HDTMA kompleksom pokazivali su jednoslojnu, dvoslojnu i pseudotroslojnu orijentaciju HDTMA+ katjona u meĎuslojnom prostoru. UtvrĎeno je da HDTMA+ katjoni formiraju particionu fazu na površini montmorionita, na kojoj dolazi do sorpcije molekula herbicida. Sa druge strane, montmorioniti modifikovani sa PTMA kompleksom pokazivali su jednoslojnu orijentaciju katjona na površini montmorionita i to na takav način da se katjoni ponašaju kao stubovi koji u zavisnosti od dimenzija dovode do širenja meĎuslojnog prostora.

AB  - BACKGROUND: Bee pollen has already proved to be a good supplement rich in iron and zinc. Studies on the application of flower pollen in the food industry and medicine have begun. Bearing in mind the prevalence of maize as a crop culture, its pollen will be easily available. The mineral composition of pollen of seven Serbian maize hybrids was analyzed in order to establish its nutritional value and the benefits of its implementation in the human diet using the inductively coupled plasma method. RESULTSThe presence of twenty four different macro- (nine) and micronutrients (fifteen) was detected. The most common minerals were phosphorus and potassium, while arsenic, cobalt, lead, nickel and molybdenum were found in some samples. CONCLUSIONComparing the results obtained with recommended or tolerable dietary intake references for adults, it was found that maize pollen can be used as a very good source of zinc, iron, chromium and manganese for humans. With regard to selenium content, pollen samples proved to be moderately good source of this important micronutrient. Contents of some elements (Fe, Zn, Mn, Cr, Se, Al and V) showed significant differences depending on hybrid type. In some samples increased concentrations of aluminum and vanadium were recorded, which may pose a potential problem due to their toxicity.

AB  - This study focuses on the mineralogical and thermal properties of clay from "Slatina" deposit, Ub, Serbia. Sampled clays were analysed by XRD, IR spectroscopy, ICP-OES, DTA, specific surface area (SSA), cationic exchange capacity (CEC), gravimetric and grain size measurements. Results show that the studied samples have a medium content of smectite-illite minerals with smaller amount of kaolinite together with quartz, feldspars and goethite. They consist generally of fine particles with medium to high plasticity. Based on their mineral composition and physical properties (grain size, plasticity, CEC) the clays are suitable as raw material for the ceramics industry.

AB  - This study was undertaken to determine the impact of the organic complex concentration on the adsorption of herbicide (acetochlor) at the surface of the organic modified montmorillonite. In this work, natural montmorillonite from Bogovina (Boljevac municipality, Serbia) was used for organic modification. Cation-exchange capacity of this montmorillonite was determined using a methylene blue method (86mmol/100g of clay). Montmorillonite has been modified first with NaCl and then with hexadecyltrimethylammonium bromide (HDTMA-bromide) organic complex. Saturation of cation exchange capacity (CEC) was 50%, 100%, and 150%. Changes in the properties of the inorganic and organic montmorillonite have been examined using the X-ray diffraction, Fourier transform infrared spectroscopy, and batch equilibrium method. Montmorillonite modified with HDTMA-bromide demonstrated higher uptake of the herbicide, compared to the inorganic montmorillonite. Comparing the values Freundlich coefficients in batch equilibrium method, it can be seen that the adsorption of acetochlor decreased in the series: 0.5 CEC HM > 1 CEC HM > 1.5 CEC HM > NaM.
