AB  - Pesticides used in coffee cultivation may remain behind and pose a risk to humans even after various processing stages of coffee beans (washing, drying, roasting, and grinding). In addition to pesticides applied to battle pests and diseases, mepiquat formation occurs during roasting. A comprehensive LC-MS/MS and GC-MS/MS multi-residue screening approach to determine pesticides in coffee was used in this study. Residues were extracted using the QuEChERS method and analyzed using multiple reaction monitoring (MRM) mass spectrometry after chromatographic separations. Good linearity (r2˃0.9919), recovery (80.2–118%), and RSD (≤19%) were obtained for the procedure including sample preparation and both instrumental techniques. Nine residues were identified as commonly present in coffee samples collected from supermarkets in Serbia. The human intake risk of pesticides was categorized and prioritized using the matrix ranking scheme. Also, health risk assessment was conducted by calculating acute and chronic hazard indices. Multi-residues were present in 79.2% of samples, whereas mepiquat chloride (88.9%) and permethrin (81.9%) were the most detected residues. Risk ranking classified mepiquat chloride, permethrin, and methiocarb sulfone in a high-risk group. On the other hand, the human health risk assessment indicated no risks in the short- and long-term and no cumulative chronic risk.

AB  - This study presents an innovative approach for the reuse and recycling of waste material, brewer’s spent grain (BSG) for
creating a novel green biocatalyst. The same BSG was utilized in several consecutive steps: initially, it served as a substrate
for the cultivation and production of laccase by a novel isolated fungal strain, Coriolopsis trogii 2SMKN, then, it was reused
as a carrier for laccase immobilization, aiding in the process of azo dye decolorization and fnally, reused as recycled BSG
for the second successful laccase immobilization for six guaiacol oxidation, contributing to a zero-waste strategy. The novel
fungal strain produced laccase with a maximum activity of 171.4 U/g after 6 days of solid-state fermentation using BSG
as a substrate. The obtained laccase exhibited excellent performance in the decolorization of azo dyes, both as a free and
immobilized, at high temperatures, without addition of harmful mediators, achieving maximum decolorization efciencies
of 99.0%, 71.2%, and 61.0% for Orange G (OG), Congo Red, and Eriochrome Black T (EBT), respectively. The immobilized
laccase on BSG was successfully reused across fve cycles of azo dye decolorization process. Notably, new green biocatalyst
outperformed commercial laccase from Aspergillus spp. in the decolorization of OG and EBT. GC-MS and LC-MS revealed
azo-dye degradation products and decomposition pathway. This analysis was complemented by antimicrobial and phytotoxicity tests, which confrmed the non-toxic nature of the degradation products, indicating the potential for safe environmental
disposal.

AB  - The occurrence of potentially toxic elements (PTEs), including twelve heavy metal(loid)s (Cd, Cr, Cu, Ni, Pb, Zn, Hg, As, Co, V, Fe, Mn), fluoride (F−), and nitrate (NO3−) was evaluated in groundwater in the copper mining and smelter area of Bor city (south Carpathian, eastern Serbia). Groundwater samples were analyzed to determine the extent of pollution, identify natural and anthropogenic input of PTEs, and estimate potential human health risks due to exposure to these substances. The results revealed that the groundwater in the study area was highly contaminated with PTEs, particularly Cu and Zn. Multivariate analysis supported the natural and anthropogenic origin of PTEs, with Fe, Mn, and F− classified as naturally occurring, NO3− resulting from agricultural activities, while other PTEs were linked to smelter/mining processes. Geospatial mapping discovered several hotspots with potential high non-cancer and cancer risks to humans through ingestion pathway. From the studied PTEs, As is the most health risk contributing toxic element. The source-specific probabilistic risk assessment indicated the most significant contribution to the hazard index and total cancer risk from accidental leakage of metallurgical wastewater and wastewater from open mine pits. Monte Carlo analysis identified the human body weight and the ingestion rate as the most sensitive risk parameters. The study underscores the need for stringent environmental management measures, emphasizing the critical role of source-specific risk assessments in mitigating potential hazards associated with metallurgical wastewater and open mine pits.

AB  - The occurrence and distribution of yttrium and rare earth elements (REYs), along with major elements and heavy metal(loid)s (HMs) in coal fly ash (CFA) from five coal-fired power plants (CFPPs), were analyzed, and the REY-associated ecological and health risks were assessed. The individual REYs in CFA were abundant in the following order: Ce > La > Nd > Y > Pr > Gd > Sm > Dy > Er > Yb > Eu > Ho > Tb > Tm > Lu. The total REY content ranged from 135 to 362 mg/kg, averaging 302 mg/kg. The mean light-to-heavy REY ratio was 4.1, indicating prevalent light REY enrichment in CFA. Significantly positive correlations between the REYs suggested that they coexist and share similar origins in CFA. REYs were estimated to pose low to moderate ecological risks, with risk index (RI) values ranging from 66 to 245. The hazard index (HI) and target cancer risk (TCR) of REYs from CFA, estimated to be higher for children (HIc = 0.15, TCRc = 8.4 × 10−16) than for adults (HIa = 0.017, TCRa = 3.6 × 10−16), were well below the safety limits (HI = 1, TCR = 1.0 × 10−6). However, the danger to human health posed by HMs in the same CFA samples (HIc = 5.74, TCRc = 2.6 × 10−4, TCRa = 1.1 × 10−4) exceeded the safe thresholds (excl. HIa = 0.63). The mean RI and HI attributed to REYs in CFA were 14% and 2.6%, respectively, of the total risks that include HMs.

AB  - This study investigated the occurrence and distribution of rare earth elements (REEs), including 14 lanthanoids, scandium (Sc), and yttrium (Y), in groundwater around a large coal-fired thermal power plant (TPP). The ICP-MS technique was used to analyze 16 REEs in groundwater samples collected from monitoring wells. REE concentrations ranged from 59.9 to 758 ng/L, with an average of 290 ng/L. The most abundant was Sc, followed by La, accounting for 54.2% and 21.4% of the total REE concentration, respectively. Geospatial analysis revealed the REE enrichment at several hotspots near the TPP. The highest REE concentrations were observed near the TPP and ash landfill, decreasing with the distance from the plant and the landfill. REE fractionation ratios and anomalies suggested the Light REE dominance, comprising over 78% of the total REEs. Correlation and principal component analyses indicated similar behavior and sources for most REEs. Health risk assessment found hazard indices (HI) of 1.36 × 10−3 and 1.98 × 10−3 for adults and children, respectively, which are far below the permissible limit (HI = 1). Likewise, incremental lifetime cancer risks (ILCR) were all below 1 × 10−6. Nevertheless, ongoing ash disposal and potential accumulation in the environment could elevate the REE exposure over time.

AB  - Molecularly imprinted polymers (MIPs) as materials with determined levels of selectivity and specificity for designated analytes have recently gained much attention in various application fields. However, with the growing adoption of green analytical chemistry (GAC) principles, it is essential to investigate the greenness of MIP synthesis and its subsequent application in sample preparation, as well as to evaluate the "green"nature of the developed analytical methodologies, such as dispersive solid-phase microextraction (DSPME). Accordingly, the main objective of this research was to evaluate the greenness of MIP-based glycidyl methacrylate synthesis and MIP use as a DSPME sorbent prior to high-performance liquid chromatography with mass spectrometry (HPLC-MS). The green perspective of MIP-DSPME prior to HPLC-MS was investigated using various analytical metric tools such as the Analytical Eco-Scale, the Green Analytical Procedure Index, and Analytical GREEnness (AGREE). Since these analytical tools are not fully implementable for the assessment of the greenness of the MIP synthesis, some alternative approaches were used to optimize the synthesis parameters to make the MIP DSPME sorbent as close as possible to the GAC principles. The calculated AGREE score (0.62) and 91 points in the Analytical Eco-Scale for the proposed DSPME technique using MIP indicated a high level of greenness.

AB  - In this work, removal of heavy metals (Cr, Mn, Co, Ni, Cu, Zn, As, Cd, and Pb) from fly ash has been studied using acid leaching and wet oxidation methods. In parallel, microwave-assisted acid digestion was applied for determination of pseudo-total concentrations of heavy metals to estimate the leaching efficiency. Multivariate statistics (Pearson correlation, principal component analysis, and hierarchical cluster analysis) have shown two dominant groups of elements, depending on their characteristics and affinity towards the ash solid phase. Thus, Cr, Zn, Mn, Co, and Ni belong to the group I, while Pb, As, Cd, and Cu belong to the group II. It was demonstrated that the wet oxidation method was more suitable than acid leaching since the reduction in metal concentration was 30 to 75 % compared to 12 to 25 % obtained by acid digestion. The influence of fly ash treatment on the residue characteristics was investigated by X-ray diffractometry and scanning electron microscopy. The analyses revealed surface and structure changes of fly ash after the wet oxidation treatment. Overall, wet oxidation could be an appropriate treatment for heavy metal removal from fly ash, providing a material that could be further used, thus reducing the risk of pollution caused by the disposal of coal combustion fly ash. © 2024, Association of the Chemical Engineers of Serbia.

Hence, a comprehensive methodology, including hydrogeochemical facies (Piper, Gibbs), irrigation indices (SAR, Wilcox), entropy-weighted water quality index (EWQI), positive matrix factorization (PMF), and Monte Carlo simulation of source-specific health risks was used in this study to analyze groundwater in the Morava river plain (Serbia). The results revealed a prevalent Ca–Mg–HCO3 groundwater type, influenced by water–rock interactions. Although groundwater was found suitable for irrigation, only 66.7 % of the samples were considered drinkable. Agricultural activities, natural processes, and municipal wastewater were identified as primary pollution sources. The incremental lifetime cancer risk (ILCR) and hazard index (HI) threshold exceedance for adults and children ranged from 8.5 % to 39 % of the samples, with arsenic identified as the most risk-contributing contaminant. These findings provide valuable insights for researchers studying groundwater vulnerability in river plains.

AB  - Conventional wastewater treatment processes are increasingly difficult to fulfill strict standards of
achieving the required quality. Therefore, it is necessary to apply processes that in an efficient and
economically justified way reach the necessary limits in order to discharge wastewater into the
recipient. The process of photolysis represents the degradation of the starting pollutant practically to
water and carbon dioxide. The whole process takes place under the action of a UV lamp that imitated
solar irradiation. The process is environmentally justified since, unlike some other advanced
oxidation processes - AOPs, there is no use of additional, hazardous, chemicals which possibly results
in the precipitates formation that are leading to further treatment. In this paper, photolytic degradation
of pesticide thiophanate methyl was performed in doubled wall quartz reactor equipped with a
thermoregulation system. Reaction was forced under Osram ULTRA VITALUX UV lamp (300W).
Kinetics of photodecomposition process was followed by pseudo-first order. In certain time periods,
specimens were sampled, filtered and monitored by UV spectrophotometer Shimadzu 1800 with an
aim to determine the concentration of xenobiotic. Complete degradation of present xenobiotics was
obtained after 240 min. With an aim to enhance the degradation process, hydrogen peroxide was
added as a boosting agent which cause a shortening in demanded time (150 min) for complete
degradation. Verification of the success of decomposition was confirmed by the obtained values of
chemical oxygen demand (COD), which reveal that the established system has a basis for real
application in industrial or municipal wastewater.

of pesticide thiophanate methyl was performed in doubled wall quartz reactor equipped with a
thermoregulation system. Reaction was forced under Osram ULTRA VITALUX UV lamp (300W).
Kinetics of photodecomposition process was followed by pseudo-first order. In certain time periods,
specimens were sampled, filtered and monitored by UV spectrophotometer Shimadzu 1800 with an
aim to determine the concentration of xenobiotic. Complete degradation of present xenobiotics was
obtained after 240 min. With an aim to enhance the degradation process, hydrogen peroxide was
added as a boosting agent which cause a shortening in demanded time (150 min) for complete
degradation. Verification of the success of decomposition was confirmed by the obtained values of
chemical oxygen demand (COD), which reveal that the established system has a basis for real
application in industrial or municipal wastewater.",

AB  - Fly ash is a by-product of coal combustion in thermal power plants. Heavy metal(loid)s
(HMs) are the most recognized among the many dangerous compounds in fly ash. These substances
may contaminate the environment and can pose a threat to human health. Various analytical
techniques are used to analyze HMs in leachate. To investigate the possibility of contamination of
the environment, heavy metals and metalloids (Pb, Zn, Mn, Fe, As, Ba, Be, Cu, Cr, Co, Cd, Sb, Se,
and V) were leached from fly ash using a toxicity characteristic leaching procedure (TCLP). The fly
ash samples used in this work were obtained from four thermal power plants (Kostolac, Kolubara,
Tent B, and Morava). Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)
technique was used to determine the concentration of these elements in the leachate. Accurate
elemental analysis was achieved with this technique. Among all analyzed metal(loid)s, Fe, Mn, Zn,
and As were the most abundant.

and their major sources to the urban environment include vehicular emissions (mobile source),
gasoline evaporation, coal burning and residential heating, and waste incineration (stationary

that they can act as a source, as well as sink, of organic compounds, especially in a water body
located in an urban city exposed excessively to the above-mentioned sources of BTEX. In this study,
we aimed to identify and quantitatively analyze VOCs compounds in sediment by using purge-andtrap (P&T) gas Chromatography-Mass Spectrometry (GC-MS).

on human health. Carbon monoxide (CO) is a pollutant of concern because it is very toxic at low
concentrations. It is an odorless and colorless gas that is very difficult to detect. In recent years,
passive sensors have been widely used to analyze CO in ambient air. The CO sensor for commercial
use must be stable during operation and have a linear and reproducible output over a long period.
Hence, developing CO gas sensors with high sensitivity, selectivity, and stability is essential. This
study compared three types of CO gas sensors: electrochemical, metal-oxide semiconductors, and
colorimetric. Each of these sensors is characterized by specific advantages and disadvantages;
therefore, their comparative analysis is presented, and their most important characteristics are
emphasized.

AB  - One of the most significant sources of drinking water is groundwater. Therefore, it is
crucial to assess groundwater quality and ascertain potential causes of contamination to address
pollution and provide people with clean drinking water. In this paper, groundwater in the Morava
River plain is investigated and analyzed for 14 physicochemical parameters, such as pH, EC, HCO3
, NO3
-
, PO4
3-
, Cl-
, SO4
2-
, Na+
, K+
, Mg2+, Ca2+, Fe, Mn, and As. To determine groundwater facies and
sources of pollution, three multivariate statistical analysis techniques were applied. Hierarchical
Cluster Analysis (HCA) was used to group groundwater samples based on their similar chemical
characteristics and to determine the dominant hydrochemical groundwater type. According to HCA
results, groundwater samples were clustered into three groups, including Cluster 1 (72.3%), Cluster
2 (19.7%), and Cluster 3 (7.9%), and the main groundwater type was Ca-HCO3 type. Factor Analysis
(FA) incorporated with Pearson correlation analysis was conducted to determine the main sources
of pollution. Water-rock interactions and agricultural practices were identified as primary pollution
sources in the investigated area.

abstract = "One of the most significant sources of drinking water is groundwater. Therefore, it is
crucial to assess groundwater quality and ascertain potential causes of contamination to address
pollution and provide people with clean drinking water. In this paper, groundwater in the Morava
River plain is investigated and analyzed for 14 physicochemical parameters, such as pH, EC, HCO3
, NO3
-
, PO4
3-
, Cl-
, SO4
2-
, Na+
, K+
, Mg2+, Ca2+, Fe, Mn, and As. To determine groundwater facies and
sources of pollution, three multivariate statistical analysis techniques were applied. Hierarchical
Cluster Analysis (HCA) was used to group groundwater samples based on their similar chemical
characteristics and to determine the dominant hydrochemical groundwater type. According to HCA
results, groundwater samples were clustered into three groups, including Cluster 1 (72.3%), Cluster
2 (19.7%), and Cluster 3 (7.9%), and the main groundwater type was Ca-HCO3 type. Factor Analysis
(FA) incorporated with Pearson correlation analysis was conducted to determine the main sources
of pollution. Water-rock interactions and agricultural practices were identified as primary pollution
sources in the investigated area.",

AB  - Dispersive liquid–liquid microextraction (DLLME) using a floating organic drop has been optimized and used for the sample preparation of four commonly used ultraviolet filter (UVF) substances in sunscreens. Plackett–Burman experimental design was used to screen 10 variables in DLLME. The most significant variables were then optimized by using a response surface method with a Box–Behnken design. DLLME followed by an optimized HPLC identified octocrylene, 2-ethylhexyl-4-methoxycinnamate, ethylhexyl salicylate, and homosalate as the frequently found UVFs in commercial sunscreens. The systemic exposure dosage and margin of safety (MoS) for the identified UVFs were estimated using in-use concentrations and application patterns. The average systemic exposure dosage values for octocrylene, 2-ethylhexyl-4-methoxycinnamate, ethylhexyl salicylate, and homosalate were 0.52, 0.61, 0.020, and 0.079 mg/kg body weight per day, respectively. Whereas the average MoS values for individual UVFs ranging from 296 to 3160 were all significantly higher than the limit value of 100, the combined exposure risks were slightly above the limit. The probabilistic health risk assessment using Monte Carlo simulation revealed that the combined MoS values were (mean, 10‰, 90‰) 342, 119, and 441, respectively. Regarding the usage of sunscreen cosmetics containing the UVFs studied, these results indicate a safety concern for those who apply multiple UVF products.

AB  - A fast and straightforward reversed-phase dispersive liquid–liquid microextraction (RP-DLLME) using a deep eutectic solvent (DES) procedure to determine free tryptophan in vegetable oils was developed. The influence of eight variables affecting the RP-DLLME efficiency has been studied by a multivariate approach. A Plackett–Burman design for screening the most influential variables followed by a central composite response surface methodology led to an optimum RP-DLLME setup for a 1 g oil sample: 9 mL hexane as the diluting solvent, vortex extraction with 0.45 mL of DES (choline chloride–urea) at 40 ◦C, without addition of salt, and centrifugation at 6000 rpm for 4.0 min. The reconstituted extract was directly injected into a high-performance liquid chromatography (HPLC) system working in the diode array mode. At the studied concentration levels, the obtained method detection limits (MDL) was 11 mg/kg, linearity in matrix-matched standards was R2 ≥ 0.997, relative standard deviations (RSD) was 7.8%, and average recovery was 93%. The combined use of the recently developed DES -based RP-DLLME and HPLC provides an innovative, efficient, cost-effective, and more sustainable method for the extraction and quantification of free tryptophan in oily food matrices. The method was employed to analyze cold-pressed oils from nine vegetables (Brazil nut, almond, cashew, hazelnut, peanut, pumpkin, sesame, sunflower, and walnut) for the first time. The results showed that free tryptophan was present in the range of 11–38 mg/100 g. This article is important for its contributions to the field of food analysis, and for its development of a new and efficient method for the determination of free tryptophan in complex matrices, which has the potential to be applied to other analytes and sample types.

AB  - Lindane belongs to the persistent organic pollutants (POPs) group, which can cause carcinogenic,
endocrine, and neurological problems in an organism. The widespread presence of lindane in the
environment demands efficient methods of its removal. In the present work, we investigated the
removal of lindane from an aqueous solution using a synthesized macroporous copolymer surface
modified with different functional groups through two-step post-functionalization. The modified
copolymer was characterized by Fourier transform infrared spectroscopy (FTIR-ATR), scanning
electron microscopy (SEM), and mercury intrusion porosimetry. For the kinetics of lindane sorption,
pseudo-first-order, pseudo-second-order, Elovich, Avrami, and fractional power models were used
via linear and non-linear regression analyses. The quality of the fitting of each model to experimental
data was assessed based on seven error functions: coefficient of determination (R2), Marquardt’s
percent standard deviation (MPSD), Chi-square statistic test (χ2), hybrid fractional error function
(HYBRID), the sum of the errors squared (SSE), sum of the absolute errors (EABS), and average
relative error (ARE). The investigation of error estimation methods showed that the pseudo-secondorder
model best fits the experimental kinetics data for both regression analyses. The mechanism of
lindane sorption was investigated by subjecting the data to the liquid film diffusion model,
intraparticle diffusion model, Bangham, and Boyd models. The results showed that intraparticle
diffusion was not the sole rate-controlling step; film-diffusion also affected the sorption process.

AB  - This study evaluated the equilibrium, kinetics, and thermodynamics of vanadium sorption from
aqueous solution onto nanocomposite functionalized with diethylene triamine in batch conditions.
The effects of temperature, solution pH, and initial concentration of vanadium were examined. The
maximum sorption capacity of vanadium on the tested sorbent was achieved at pH 6. The sorption
capacity increased with increasing temperature and initial concentration. The equilibrium adsorption
data were analyzed using Langmuir, Freundlich, Temkin, Jovanovic, Toth, Sips, Khan, and RedlichPeterson isotherm models. The kinetics data were studied using pseudo-first-order, pseudo-secondorder, the fractional power, Elovich, and Avrami models. A non-linear fitting method was used to
compare the best fitting of the equilibrium and kinetic data. The sorption equilibrium data were best
represented by the Langmuir, Khan, Toth, and Redlich–Peterson isotherms. The adsorption kinetics
was estimated to follow the pseudo-second-order kinetic model. The mechanism of vanadium
sorption was analyzed with intra-particle, Bangham, Boyd, and liquid film diffusion models. It was
observed that the sorption process was controlled by the film-diffusion as well as the pore-diffusion.
Thermodynamic parameters (change of standard enthalpy (ΔH°), standard entropy (ΔS°), and
standard free energy (ΔG°)) suggested that the sorption of vanadium onto functionalized
nanocomposite was a spontaneous and endothermic process.

AB  - Acid mine drainage is a challenging environmental problem caused by mining activities.
Long-term copper ore exploitation and vast amounts of mining waste lead to severe soil
contamination as well as river and groundwater pollution. In this paper, research is focused
on utilizing waste mine waters and off-balance parts of the mine deposit (such as flotation
tailings) and converting their negative characteristics to an environmentally friendly one. In
the authors’ previous work, acid mine water from Robule, which is part of the Bor copper
mining and smelting complex in Serbia, was successfully treated using flotation tailings, and
the resulting solution was suitable for safe discharge. This paper investigates the characteristics
of the solid residue that remained after the treatment of the modified flotation tailings in order
to evaluate the possibility of its safe disposal back into the environment. The solid residue
was subjected to TCLP and EN 12457-4 tests as standard procedures that assess the leaching
characteristics of a material. The solid residue was also exposed to long-term leaching with
melted snow to simulate environmental conditions for one year. This drainage water was
analyzed and compared with the results of the standard leaching procedures. The investigated
treatments lead to improved economic and environmental effects, while the process itself is
adjusted to preserve the environment.

AB  - Deep eutectic solvents (DESs) have been recognized as promising solvents due to their purity, high conductivity, bio-degradability, thermal stability1. These environmentally friendly solvents are important tools in the creation of green and sustainable technologies. The use of DES in polymer science is highly promising for the development of novel green materials. Therefore, DESs have been used in molecular imprinting in order to improve the properties of molecularly imprinted polymers (MIP). DES are most often prepared by combining two classes of compounds: hydrogen bond donor, HBD (such as amide) and hydrogen bond acceptor, HBA (such as quaternary ammonium salt) in different molar ratios2. By mixing these components in with appropriate molar ratios, eutectic mixtures are formed in a liquid state at temperatures below 100 °C. This study reports the ability of DES-MIP as a sorbent for the removal of aromatic amine from plastic packaging. In order to obtain the most effective sorbent, DESs are prepared by combining choline chloride as HBA with different HBDs, such as urea, glycerol, and ethylene glycol. The results showed that choline chloride:urea was the most suitable DES as modifier of MIP.
