AB  - Toxic secondary metabolites of some fungi (mainly representatives of Alternaria, Aspergillus,Fusarium and Penicillium genera) may contaminate agricultural products, representing serioushealth hazards both to humans and animals. Along with this, the economic losses due to themycotoxins’ presence in feed production, including crop and animal feedstuff processing anddistribution, motivated the plentiful research of detoxification strategies.

Recently, many investigations are directed toward plant-derived products thatcan efficiently adsorb mycotoxins in their native (biosorbents) or modified forms (e.g. activatedcarbon, biochar etc.). These renewable, easily accessible and readily prepared sorbents areeconomically viable and safe alternatives for mycotoxin decontamination of feed resources.Organic polymers (chitosan, cellulose, etc.) as well as synthetic polymers, such as polyvinylpyrrolidine, also might reduce mycotoxins’ level in feed. Besides these conventional methods,new research trends are nanotechnologies, the promising, effective, low-cost way formycotoxins’ removal.

AB  - Microplastics (MPs), the long-lasting anthropogenic contaminant omnipresent in the environment, have become a threat to ecosystems’ function and living organisms’ health, potentially harming the food chain globally. The presence of MPs emerged on a worldwide scale, while the evidence of microplastic particles is already being detected in human tissues. Terrestrial environments are sinks for plastic deposition and are one of the main routes of MPs reaching the groundwater and water bodies. In this regard, urban soils could significantly contribute to overall plastic pollution even though it have been mostly neglected by the research investigations carried out so far. Herein, we investigated MPs abundance in the soils of Belgrade, a city located in the northeast of Serbia, the capital and the most populated city in Serbia. Two sampling points chosen to represent the pollution gradient were the city center zone, close to the highway (BG1), and Košutnjak, the urban forest area around 7 km distant from the center (BG2). MPs extraction was performed using a density separation method, by saturated NaCl solution (1.2 g cm-3). Before extraction, soil organic matter was digested by 30% H2O2. Found average concentration of MPs was 400 items per kg of dry soil sampled in BG1. Soil from Košutnjak contained no MPs according to our findings. MPs abundance found in sampled soils from Belgrade is in agreement with previous reports analyzing urban areas. Isolated plastic particles were identified and counted using a polarizing microscope (Carl Zeiss Jena Pol-U). All found items were white/transparent fragments, characterized afterward by ATR-FTIR spectroscopy using a Thermo Scientific Nicolet iS50 spectrophotometer. Detected polymer types were polystyrene (PS) and phosphorylated cardanol prepolymer (PCP), suggesting the insulation, packing, and rubber materials as potential pollution sources. Transportation, overload of customer goods and packaging, construction, and building activities are the prevailing anthropogenic origins of MPs accumulation in urban environments. Further investigations will aim to reveal the relations between MPs and other pollutants and the potential impact on soil biota.

AB  - Microfibers, as a considerable component of microplastic pollution in the environment have received
notable attention during past years. Fast fashion and extensive use of synthetic and semi-synthetic outfits,
aging, and discharge of used textile items are dominant sources of microfiber generation and ending up in
urban soils. Herein, we examined microfibers' presence in the urban soils of Sremska Mitrovica and Bor.
A flotation method based on density separation using saturated NaCl solution was utilized to assess
microplastics concentration in soils. The abundance of microfibers was 200 and 600 items per kg of soil,
respectively. Fiber structure was confirmed by ATR-FTIR analysis. Items isolated from soil from Sremska
Mitrovica contained the natural fiber of cotton, while microfibers detected in soil from Bor referred to
semi-synthetic polymer, viscose, i.e. rayon. Despite similar chemical structures based on cellulose,
differences in IR spectra allowed the distinguishing of these fiber types. This paper provides insight into
the current state of environmental pollution by microplastic fibers and suggests potential origin. More indepth
research on fiber content in soils, measures of prevention, and subsequent remediation should be
carried out to face the challenge of microfibers presence in the ecosystem, their entering the food chain,
and their impact on biota.

AB  - This article presents studies, whose main goal was to minimize food waste. To achieve this goal, it is necessary to expand the scope of their application, for example, for the purification of polluted water from heavy metals. Millions of tons of waste from the fruit and vegetable industry, including pomace of apples and beetroots, are thrown into landfills, posing a danger to the environment. In order to solve the problems with the disposal of these wastes, the authors investigated their sorption potential for the removal of lead from wastewater. The sorbents, dried apple (AP), and beetroots (BR) pomaces were characterized by various methods (study of composition, zeta potential, FTIR-ATR, and SEM-EDX). Various models of sorption kinetics and sorption isotherms were analyzed. Kinetical studies under optimal conditions showed that the sorption process occurs through complexation and ion exchange and the determining stage limiting the rate of sorption is the diffusion of lead ions in the sorbent. The maximum sorption capacity was 31.7 and 79.8 mg/g for AP and BR, respectively. The thermodynamic data revealed the spontaneous sorption of lead ions by sorbents. The temperature rise contributes to the sorption increase by the AP sorbent, while for the BR sorbent, the opposite effect is observed. The obtained results showed that apple and beetroots pomaces can serve as effective renewable materials for the preparation of sorbents, contributing to the solution of complex environmental problems.

AB  - This study focuses on establishing an efficient two-step technology, which includes: (1) consecutive adsorptiondesorption,
using cellulose-based membranes, bCells, and (2) photocatalytic degradation of the fungicide
thiophanate-methyl (TPM), using synthesized Ag-P25 and Ce-P25 catalysts. The catalysts, obtained by
controlled deposition of Ag2O/Ag and CeO2 onto P25 TiO2 carrier (Degussa), were characterized using ATRFTIR,
XRPD, BET, FESEM, HRTEM, HAADF-EDS and UV–DRS techniques. In order to establish a feasible purification
technology, preconcentration of TPM was performed by adsorption, achieving 75.5 and 92.9 mg/g of
TPM removal using bCell-EpL and bCell–EpL–TA membranes, respectively, followed by efficient desorption (>
95%) that provided acceptable TPM concentration for photodegradation experiments. Under optimal conditions
(0.07 g/L of both catalysts), complete degradation of TPM (5 mg/L) occurred within 2 h, compared to 4 h for the
base TiO2 P25. Measurements of quantum yield and the results of HPLC-MS analysis, alongside DFT calculation,
assisted in understanding the TPM degradation pathways. New degradation products were detected and proposed
from HPLC–MS analysis. Embryotoxic assays, performed on zebrafish (Danio rerio), applied to estimate the
toxicity evolution of time-dependent generated TPM degradation products, showed low embryotoxic potential.
Chemical oxygen demand (26 mg O2/L) confirmed low ecotoxicological pressure of effluent water.

МАТЕРИЈАЛ и МЕТОД: Узорци земљишта су прикупљани помоћу лопате од нерђајућег челика и
текстилних врећа, на травнатој површини у близини Специјалног резервата природе Засавица, на
дубини од 0-20 cm. Узорци су сушени на ваздуху две недеље и просејани кроз сито од 2 mm. Након
просејавања, узорци су сушени на 60˚C у пећи до константне тежине, а затим су мерена три
репликата од укупно 15 g узорка за анализу. На почетку је земљиште третирано са 60 ml 30% H2O2
како би се разорила органска материја земљишта. Како би се постигла боља екстракција МП,
суспензија је подвргнута ултразвучном третману у трајању од 10 минута, имајући у виду да МП
имају тенденцију да буду инкорпориране у агрегате земљишта. Након тога, дигестија је настављена
на 60˚C током 24h. Изолација МП извршена је методом раздвајања по густини. Суви остатак
земљишта који је остао након дигестије прекривен је засићеним раствором NaCl. Густина раствора
NaCl била је 1,2 g cm-1. Суспензија је стављена у ултразвучно купатило на 15 минута и остављена
преко ноћи како би се честице могле редистрибуирати по густини. Горњи слој супернатанта је
филтриран кроз Whatman стаклени филтер (величина пора 1,6 µм, пречник 25 mm). МП су
посматране и пребројане помоћу поларизационог микроскопа (Carl Zeiss Jena Pol-U).
РЕЗУЛТАТИ и ЗАКЉУЧЦИ: У складу с резултатима, узорци земљишта су садржали 800 честица по
kg земљишта, односно у измерених 5 g земљишта у просеку смо нашли 4 честице. Преовлађујући
облици МП били су фрагменти, док је величина била у распону од 50-500 µм. Боја честица је била
бела/провидна. Претпостављени доминантни извори остатака МП на овом подручју, које се сматра
незагађеним, могли би бити производи за свакодневну употребу, као што су амбалажа за храну и
пиће, козметички производи, текстил, гуме итд. Претпоставља се да индустрија и пољопривреда не
доприносе у значајној мери доказаном присуству МП. Метода која користи засићени раствор NaCl
даје информације само о честицама полимера са густином мањом од 1,2 g cm-1. Стога се очекује
да ће екстраховане честице бити остаци полимера као што су LDPE и HDPE (полиетилен ниске и
високе густине), PP (полипропилен), ABS (акрилонитрил бутадиен стирен), PC (поликарбонат),
HIPS (полистирен високог утицаја), или PA (полиамид). Јасан увид у утицај МП на екосистем тек
треба да се испита. Будућа истраживања биће усмерена на утицај МП на важна физичко-хемијска
својства земљишта и живи свет, одређивање типа и карактеризација МП и њеног главног извора
порекла на проучаваном подручју, како би се у будућности примениле одговарајуће мере за
смањење загађења пластиком.

AB  - Microplastics (MPs) are a newly acknowledged, pervasive pollutants found even in distant Earth
areas and represent a matter of global concern. This study inspects, for the first time, microplastic
content in terrestrial environments in the city of Bor, known as one of the most polluted industrial
cities in Serbia. Soils from the park in the II kilometer and the periphery of the Bor (Brezonik
settlement) were collected and analyzed. Plastic particle extraction from the soil matrix was
performed using the flotation method based on density separation. MP content differed significantly
between the two sites. Urban soil contained around 3800 items kg-1
, while suburban held 600 particles
per kilogram. The outstandingly high difference likely originates from the distinction in the
anthropogenic activity levels of the two localities. There was no notable difference in appearance. All
extracted items were white to transparent fragments. The morphological shape of plastic particles
indicated defragmentation as a governing origin source. Future investigations should be concentrated
on the MPs' correlation with other contaminants, namely heavy metals, and the eventual recognition
of MP`s role as the metal pollution vector in the investigated area

tincture preparation. In this research, samples of this medicinal plant were collected in
Belgrade, Bor, Vršac, and Sremska Mitrovica in Serbia, during the spring of 2021. This
study assessed the levels of toxic and essential elements accumulated in theabove-ground
parts of a plant, and herbal infusions, and ethanolic extracts prepared of same aerial parts
of plant. The concentration of elements: As, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Se, Zn, S,
P, Mg, K, and Ca was determined by inductively coupled plasma optical emission
spectroscopy (ICP-OES). Translocation factors were calculated for each sampling site,
followed by correlation analysis, in order to investigate elements distribution and

AB  - Microplastic particles (MPs) emergence and expansion have occurred rapidly and almost imperceptibly on a worldwide basis. Its presence and persistence in terrestrial environments recently started attracting considerable attention from scientific researchers, policymakers, the media, and the general public. Several methods were developed in order to isolate MPs from complex soil samples. Density separation demonstrated to be the most efficient and cost-effective to date It consists of the following steps: soil sieving, grinding and measuring, MPs extraction using the saturated salt solution of the appropriate density higher than the MPs that need to be isolated, supernatant filtration, and visualization of MPs adhered to filter. Several approaches could be applied to soil MPs separations, considering the utilization of different extracting solutions, working conditions, and phases order, which we investigated herein. As soil samples contained around 5% of organic matter (OM), the first protocol implied organic matter digestion using 30% H2O2 before the extraction, while the second one was performed vice versa. In both protocols, the extraction solvent that was used was saturated NaCl solution, density 1.2 g cm-1. According to the obtained results, and bearing in mind the fact that MPs could be entrapped in soil aggregates, OM digestion before the extraction was considered suitable to continue the investigation. In the following protocol, digestion was conducted at different temperatures and durations of 7 days at 25˚C (room temperature) and 24h at 60˚C, respectively, which enabled more efficient OM removal. The temperature and time of exposure may need additional tuning according to the soil type. While using NaCl solution, only polymers with a density lower than 1.2 g cm-1 could be extracted, so in the next procedure, it was replaced by a saturated solution of ZnCl2, which density could go up to 1.9 g cm-1. Hence, the final protocol based on the previous optimization involved digestion with H2O2 at 60˚C for 24h, followed by covering the dry residue with saturated ZnCl2 solution. The mixture was left overnight for density separation. The upper layer of the solvent where the MPs tend to concentrate was taken by a glass dropper and filtered through a Whatman glass filter (pore size 1.6 μm, diameter 25 mm). Achieved efficiency regarding OM reduction rate and MPs extraction on examined soils was satisfactory for further investigations.

AB  - Anacamptis morio occurs on a wide range of habitats showing distinct tolerance to heterogeneous
edaphic conditions. Assessment of Li, B, Ba, and Sr phytoavailability in the soils of western
Serbia, and metal(oid) uptake by A. morio provided new information on less studied elements and
revealed their relatively high mobility in the soil-orchid system. Although previous studies have
found that A. morio prefers neutral and calcareous soils, our study shows that it also inhabits ultramafic
and siliceous sites characterized by pronounced differences in soil chemical properties. BCR
sequential extraction identified up to 60% of Li and more than 80% of Ba and Sr content as potentially
phytoavailable. The total element analyses using ICP-OES showed that B, Ba and Sr predominantly
accumulated in the roots, but did not exceed thresholds considered potentially phytotoxic.
It revealed the exclusion strategy of A. morio which enables it to tolerate differences in elemental
composition of contrasting bedrock types. The highest Li concentrations were detected in leaves,
pointing to significant Li mobility within the plant. The contents of Li and Ca were highly positively
correlated, which may result from Li physicochemical properties that are similar to those of alkali
metals, allowing it to share the same transport carriers. Thus, Li could be easily transported to the
aboveground plant parts and accumulated mainly in the organs with the highest Ca content,
which was confirmed in this study. Bioconcentration factors >1 were detected only for B and Sr in
all plants analyzed, irrespective of the bedrock type.

AB  - The peach stones and kernels are easily available biowaste which could be useful for the extraction of nutritionally important compounds such as fatty acids. Except in industry, characterization of stones and kernels could be useful in pomology to describe different cultivars, and for selecting new parents in a breeding program. A total of 25 samples of stones and kernels from various peach cultivars that differed in origin and ripening time, but growing in the same climatic conditions, were characterized by fatty acids composition and physical properties. This work confirmed that unsaturated fatty acids (oleic and linoleic fatty acids) were the most represented in peach kernel oil and their content depended of peach genotype. Additionally, the fatty acids in combination with length, weight, and moisture of peach kernels could be used as a parameter of authenticity assessment. This research may contribute for the peach cultivar discrimination and recommendation of cultivars/genotypes with high kernel quality which could be used for the extractions of oil rich in unsaturated fatty acids and further use in food, pharmaceutical and cosmetic industry. Besides, selected cultivars could be used in breeding programs, for creating new genotypes for oil production.

AB  - A detailed investigation of significance of the infrared (IR) spectroscopic branching factor (CH2/CH3; the ratio of methylene and methyl group peak heights at 2917-2921 and 2951-2954 cm(-1), respectively in the IR spectra) for characterization of alkane structure, geochemical properties and viscosity of 76 oil samples was performed. These oils, originating from 13 Serbian oil fields in SE Pannonian Basin, differ according to source and depositional environment of organic matter (OM), as well as by thermal maturity and biodegradation stage. Methylene and methyl asymmetric stretching peak absorbances were used for the branching factor calculation. CH2 peak positions exhibited 3-4 cm(-1) red shift with increasing the CH2/CH3 ratio, due to a greater contribution of trans vs. gauche rotamers in aliphatic chains. Comparing IR spectra of the oils and model n-alkanes, it was established that the average (CH2)(n) methylene chain length per CH3 group varied from n = 3.5 to 6.5. The CH2/CH3 ratio showed significant concordance with geochemical parameters, enabling clear distinction of the oils according to source and depositional environment of OM. At the same time, dependence of the CH2/CH3 ratio on oil maturity in the range from immature to mature was not observed, allowing for an accurate determination of oil genetic types irrespective of maturity. The CH2/CH3 ratio showed good accordance with oil biodegradation scale and oil viscosity.

AB  - Coal is a well-known fossil fuel. It was used as a non-renewable energy source for several centuries. Nowadays it is mainly used for electricity generation in power plants or heat generation for industrial and home utilization.
There are many types of coal that differ in composition and calorific value, as well as in the amounts of undesired hazard substances produced by combustion. Depending on the coal composition, environmental impact can be reduced by its treatment before combustion. One of the cheap and effective methods is the chemical leaching of coal that reduces sulfur content and the amount of mineral matter (ash). Lowering the ash amount increases the calorific value of coal, reduces its transportation cost, and reduces the negative environmental impact of toxic elements, which are usually present in ash. Another benefit of coal leaching, that results from lowering the sulfur content is reduced emission of toxic gases (SO2 and SO3) during combustion. In order to determine the optimal leaching conditions for the treatment of different types of coal, numerous studies have been done, investigating various chemical reagents, including inorganic and organic acids, alkalis, oxidative reagents, and their combinations [1, 2]. The key parameters that effect leaching efficiency are type and concentration of reagent, reaction temperature, the mass ratio between coal and leaching reagent, coal particle size, and reaction time. The degree of leaching efficiency is measured by the level of demineralization and desulphurization [3]. The current review summarises recent results and further plans for the development of an efficient and environmentally friendly method for the chemical leaching of Serbian sub-bituminous coal.

AB  - All over the world, huge amounts of coal are available and it is utilized in large quantities for different
purposes. The coal combustion causes environmental problems, such as the release of toxic metals
and other pollutants into wastewaters, emission of noxious gases, produce of ash dumps, etc. One of
the solutions for the reduction of environment pollution, caused by coal combustion, is
demineralization and desulphurization of coal. In that sense, treatment of coal by different chemical
reagents becomes important. A subbituminous coal, used in this study was taken from the Bogovina -
East field (Lower Miocene » 20-16 Ma) of the Bogovina Basin, which is located in Eastern Serbia. The
sample was selected based on the previous studies of Bogovina - East field which indicated a high
amount of sulphur, relatively high percent of mineral matter and considerably amount of liptinites
for humic coal, which represent the most reactive maceral group. The aim of the study was an
attempt to reduce the amount of ash and sulphur in coal, keeping the organic matter unaltered as
possible, using simple and cheap method e.g. treatment with hydrochloric acid (HCl). Ash and total
sulphur content was determined before and after HCl leaching. In addition characteristics of initial
and treated coal were tracked by X-ray diffraction (XRD) analysis and Fourier-transform infrared
(FTIR) spectroscopy. The obtained results showed that the high percentage of deashing (» 80 %) was
achieved with cheap hydrochloric acid. XRD analysis of ash before and after sample treatment
provides more information about mineral phases in coal and effects of chemical leaching. FTIR
analysis indicates almost no changes in structure of coal organic matter after treatment by HCl,
which is important for further coal usage (e.g. combustion). On the other hand, the applied chemical
leaching with HCl had low impact on the sulphur content in Bogovina coal (desulphurization
percentage » 8 %). Therefore, in future research other reagents for efficient desulphurization should
be investigated.

AB  - Society intensively attempts to face worldwide environmental health issues menacing soil, water, and other
environmental media, especially in the last decades. One of the major threads and the most substantial
concerns are heavy metals, known for their high toxicity and difficult degradability. The need for an
efficient, low-cost, and sustainable approach to this problem led to the development of phytoremediation.
This promising remediation strategy implies plant species utilization to isolate contaminants and minimize
environmental risks. Plants able to inhabit contaminated sites and accumulate extraordinarily high
concentrations of heavy metals, with no toxic effects, are called hyperaccumulators. Some of them belong
to the group of aromatic and medicinal plants, containing natural substances widely used in food, cosmetics,
and farmaceutical industries. Owing to the secondary metabolites biosynthesis and distinctive
morphological features, medicinal plants with phytoremediation capabilities seem to be one of the possible
choices for utilization in the remediation of contaminated lands. According to the published data, the most
suitable aromatic plants for heavy metal contaminated soils remediation belong to the families: Asteraceae,
Geraniaceae, Poaceae, and Lamiaceae. As researches revealed, the percentage yield of the essential oil
(EO) distilled from the medicinal plants enhances with the increased heavy metal stress. Besides, it has
turned out that heavy metals do not significantly contaminate essential oils, contrary to the expected. Thus,
medicinal and aromatic plants hold great phytoremediation potential while simultaneously enabling the
production of essential oils. Their usage has been proposed as feasible and profitable, providing multiple
benefits from both environmental and economic aspects.

suitable aromatic plants for heavy metal contaminated soils remediation belong to the families: Asteraceae,
Geraniaceae, Poaceae, and Lamiaceae. As researches revealed, the percentage yield of the essential oil
(EO) distilled from the medicinal plants enhances with the increased heavy metal stress. Besides, it has
turned out that heavy metals do not significantly contaminate essential oils, contrary to the expected. Thus,
medicinal and aromatic plants hold great phytoremediation potential while simultaneously enabling the
production of essential oils. Their usage has been proposed as feasible and profitable, providing multiple
benefits from both environmental and economic aspects.",

AB  - The study is focused on the determination of the most effective chemical leaching process for the simultaneous demineralization/deashing and desulfurization of subbituminous coal from the Bogovina Basin. Coal was treated for 30 min, at different temperatures, using variable concentrations of hydrochloric, nitric, acetic and citric acids; hydrogen peroxide, mixture of hydrogen peroxide and nitric acid (pH 2), as well as by the stepwise leaching process (nitric acid + mixture of hydrogen peroxide and nitric acid, pH 2). The changes in mineral composition, caused by the chemical leaching, are followed using X-ray diffraction, whereas alterations of coal organic matter are tracked by Fourier-transform infrared spectroscopy and the content of fixed carbon. Inorganic acid leaching, regardless of the temperature and acid concentration, enabled the successful deashing of coal, whereas the percent of desulfurization was insufficient. The organic acid leaching was not satisfactory for both, deashing and desulfurization. Leaching by H2O2 and H2O2/HNO3 mixture (pH 2) resulted in moderate desulfurization, but the ash reduction was low. The most suitable method for the simultaneous effective ash (78 wt.%) and the sulfur (66 wt. %) removal from Bogovina coal is the two-step leaching, combining 10 vol. % HNO3 and mixture of 35 vol. % H2O2/10 vol. % HNO3 of pH 2 at 60 degrees C.

AB  - In this study concentration of toxic elements As, Cd, and Pb was determined in
different soil types and belonging orchid species Anacamptis morio vital parts, in order to
examine accumulation patterns and provide new insights about potential use of this
orchidin bioremediation technology. The soils developed on limestone, serpentine, and the
chert were subjected to the BCR sequential extraction. Samples of orchid root and tuber,
as underground parts, and stem, leaves, and inflorescence, as above-ground organs, were
also analyzed for content of As, Cd and Pb. During this research, it was observed that metal
content in soil is directly proportional to its content in the plant, more specifically in roots,
which suggest that A. morio can potentially be used in phytostabilization of contaminated
sites. Values for BCF factors showed Cd immobilization in roots regardless of the soil type.
Certain level of arsenic was trasfered from root to leaves indicating potential for
accumulation of this element into aboveground organs. Assessment of the
phytoremediation potential of this orchid or another plant species from diverse
environments is important as it provides information about possibility of their future
application in environmental remediation programs.
