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 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  - Population growth, urbanization, industry, floods, and agriculture globally degrade groundwater in river plains, necessitating action for its quality assessment and management. 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  - Potentially toxic elements (PTEs) are transferred to vegetables primarily through
agricultural soil or irrigation water. PTEs in agricultural soil originate from pedogenic and
anthropogenic sources. In most cases, soil contamination with these elements happens via river
systems or air pollution. Furthermore, food is now imported from many regions and countries, where
it is grown in various conditions and on various agricultural lands. Peppers (Capsicum annuum) are
popular vegetables in Serbia and worldwide. They are consumed in numerous dishes as fresh fruits,
spices, or ingredients. Peppers are reach source of carotenoids, vitamins, antioxidant compounds,
and other nutritive compounds. This study aimed to estimate the human exposure to thirteen PTEs
present in fresh, dried, and processed peppers obtained from the Serbian market. The exposure
assessment was conducted for people in four regions of Serbia by calculating the target hazard
quotient (THQ) and carcinogenic risk (CR). The comparison across areas was made due to
significant disparities in pepper consumption between them.

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

, 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  - The overall quality of processed food depends on many processing parameters such as temperature,
processing time, mixing speed, pressure, pH value, size of food pieces, type of added ingredients, etc. The
goal of food products devel- opment is not only to improve the quality of the final product but also to reduce the
energy consumption and to improve resources management. Independent evaluation of a single parameter or
response is not the best way to set and optimize experiments, because improving one response by controlling
one parameter can negatively affect other responses. Experi- mental design is frequently used for experiment
planning when multiple variables should be optimized, while the desirability function allows the determination of
operating conditions that provide the “most desirable” response values. The desirability function allows the
optimization of several responses simultaneously and the determination of the overall/cumulative/global quality.
In this way, it is possible to determine the most suitable conditions for achieving the best overall product quality.
In the desirability function, all responses are transformed into dimensionless individual desirability functions
(di), which take values from 0 to 1. The value 0 indicates an undesirable response of the system, while the value
1 represents the most de-sirable response. All values between 0 and 1 indicate more or less desirable responses.
There are three different equations for evaluating individual desirability functions depending on whether it is
ideal for the response to be maximal, minimal or to have some target value. After calculating the individual
desirability functions, they are combined into one global/overalldesirability function (D) [1,2]. If the value of this
function is different from 0, it means that for all responses, the desired responses were achieved at the same
time. If the value of the D is equal to 0, it means that for at least one response the desired response has not
been achieved. The overall desirability function represents the geometric mean of individual de- sirability
functions. When applying the experimental design, this means that one composite desirability function is
obtained for each experiment. The function D with the highest value represents the experimental conditions
under which the most optimal responses of the system are obtained, i.e. the best quality of the final product.
Various quality parameters of foodproducts, such as color, taste, odor, the content of minerals, vitamins, fibers,
appearance, texture, etc., can be measured as system responses. However, despite the advantages of this
approach, the traditional approach that uses the optimiza-tion of only one factor and one response is still the
most used.

AB  - Heavy metal(loid)s (HMs) play an important role in economic development since they are used in various branches of industry. However, all industrial activities emit HMs into the environment, where they are no longer useful but potentially toxic. It has been observed that HMs enter the soil and sediment, and potential human health risk may arise due to their excessive accumulation. Having in mind the importance of assessing the risk due to HMs in these media, we analyzed published works in the last decade and created a summary of exposure factors in health risk models for HMs in soil and sediment. This analysis revealed a remarkable increase in the number of publications about health risk assessment of HMs, especially in the last few years. Since many differences in the values of the exposure factors and their distributions were noted, this study focused on elucidating these differences. Non-carcinogenic and carcinogenic health risk assessment models were evaluated through a deterministic approach that is prevalent in use, and a probabilistic one, which is gaining more and more attention in research. In the end, guided by the studied literature, we propose the values and distributions for the exposure factors.

AB  - Cilj ovoga istraživanja bio je unapređenje funkcionalnih i tehnoloških svojstava sušene konzumne i začinske paprike kroz primenu različitih predtretmana i metoda sušenja. Istraživanja su obuhvatila ispitivanje nutritivnih i antioksidativnih parametara svežih plodova i nutritivnih, antioksidativnih i fizičkih parametara prerađenih plodova konzumne i začinske paprike. Ispitan je uticaj različitih predtretmana, kao što su blanširanje, hemijski predtretman, ultrazvuk i njihove međusobne kombinacije. Dodatno, proučavan je i uticaj metoda sušenja - sušenje u tunelskoj sušari strujom toplog vazduha i sušenje postupkom liofilzacije. Glavni cilj je bio utvrđivanje najpogodnije kombinacije predtretmana i metoda sušenja za očuvanje nutritivnih, antioksidativnih i senzornih karakteristika sušene paprike. Frakcioni faktorijski dizajn je upotrebljen za proučavanje uticaja ovih faktora.
U okviru prvog dela istraživanja izvršena je analiza mineralnog sastava komercijalno dostupnih svežih i prerađenih paprika kao i analiza sadržaja vitamina C kod četiri sorte konzumne paprike u tri stepena zrelosti. Takođe je izvršena i procena dijetetskog unosa minerala i zdravstvenog rizika koji potiče od toksičnih elemenata usled konzumacije plodova paprike. Rezultati ovih analiza ukazali su da plodovi paprike ne predstavljaju značajan izvor minerala, gde količine prisutne u prosečnim porcijama za decu i odrasle nisu dovoljne za zadovoljenje preporučenih dnevnih potreba. Izuzetak su bili određeni kiseli i sveži plodovi koji predstavljaju značajniji izvor Cu, Cr i Mo. Analizom sadržaja minerala u tri stepena zrelosti kod sorte Kurtovska kapija zapaženo je da se sadržaj minerala kontinualno menja tokom sazrevanja ploda što se ogleda u višem usvajanju K, Zn, Mg, Cu, B i gotovo stalnoj cirkulaciji Mg i Fe do pune zrelosti ploda. Rezultati ispitivanja zdravstvenog rizika su ukazali da plodovi paprike i njihovi proizvodi ne nose zdravstveni rizik za decu i odrasle usled unosa toksišnih elemenata kao što su Al, Hg, Cd i As. Većina analiziranih paprika je bila odličan izvor vitamina C sa sadržajem L-askorbinske kiseline većim od 100 mg/100 g, što znači da konzumacijom 100 g sveže paprike može se zadovoljiti preporučeni dnevni unos vitamina C.
U drugom delu istraživanja izvršena je analiza uticaja određenih predtretmana na mineralni sastav, sadržaj ukupnih fenolnih jedinjenja, antioksidativnu aktivnost i sadržaj L-askorbinske kiseline. U prvoj seriji eksperimenata ispitivano je ispiranje makro-, mikro- i elemenata u tragovima tokom ultrazvučnog pretretmana u vodi i rastvoru sirćetne kiseline. Za ovaj set eksperimenata upotrebljeni su plodovi sorte Kurtovska kapija. Do najvećih gubitaka minerala je došlo tokom prerade zelenih plodova, dok je ultrazvučni predtretman sa sirćetnom kiselinom poboljšao ekstrakciju toksičnih elemenata kao što su Al, Hg i As. Iako je ultrazvučni predtretman u rastvoru sirćetne kiseline doprineo najvećem uklanjanju toksičnih elemenata istovremeno je uticao i na značajne gubitke Fe (do 77% ukupnog gvožđa). U drugoj seriji eksperimenata ispitivan je uticaj ultrazvučnog, hemijskog i toplotnog predtretmana na sadržaj ukupnih fenolnih jedinjenja, antioksidativnu aktivnost i sadržaj L-askorbinske kiseline kod začinske paprike. Najveći uticaj na sadržaj ukupnih fenolnih jedinjenja i L-askorbinske kiseline od primenjenih predtretmana imala je temperatura predtretmana, gde su više temperature izazvale veće gubitke (50 i 80 oC). Primenjeni predtretmani nisu značajno uticali na antioksidativnu aktivnost prethodno tretirane začinske paprike.
U trećem delu istraživanja izvršeno je ispitivanje uticaja primenjenih predtretmana i metoda sušenja na kvalitet sušene konzumne i začinske paprike. Kod sušene začinske paprike rađene su sledeće analize: mineralni sastav, sadržaj ukupnih polifenola, sadržaj ukupnih karotenoida, antioksidativna aktivnost, sadržaj L-askorbinske kiseline, boja (CIELab i ne-enzimatski indeks tamnjenja), tekstura, morfološke karakteristike i mikrobiološka aktivnost kod sušene začinske paprike, dok je kod sušene konzumne paprike ispitivan sadržaj L-askorbinske kiseline i mikrobiološka aktivnost. Cilj je bio da se utvrdi uticaj različitih faktora (vreme predtretmana, temperatura predtretmana, primenjeni aditiv, pH vrednost rastvora za predtretman, primena ultrazvuka, masa uzorka koji se tretira, veličina komadića i način sušenja) na navedene parametre kvaliteta sušene paprike. Nekoliko faktora je značajno uticalo na kvalitet sušene začinske paprike. Metod sušenja je značajno uticao na sadržaj ukupnih polifenola i L-askorbinske kiseline, crvenu
boju (parametar a*) i rehidrataciju (u početnim fazama rehidratacije). Vreme predtretmana je značajno uticalo na antioksidativnu aktivnost merenu FRAP testom, sadržaj L-askorbinske kiseline, parametre boje a*, C* i ne-enzimatski indeks tamnjenja. pH vrednost je imala značajan uticaj na teksturu sušenih komadića. Temperatura predtretmana je značajno uticala na sadržaj L-askorbinske kiseline. Analizom ukupnog kvaliteta, pomoću funkcije poželjnosti, koja objedinjuje sve odgovore sistema za sušenu začinsku papriku utvrđeno je da dva faktora imaju statistički značajan uticaj: ultrazvuči predtretman i vrsta primenjenog aditiva. Rezultat ove analize je ukazao da je ultrazvuk imao negativan uticaj na ukupan kvalitet sušene začinske paprike, dok je kalijum-metabisulfit bio bolji aditiv u odnosu na limunsku kiselinu. Kod plodova sušene začinske paprike utvrđeno je da metod sušenja ima statistički značajan uticaj na sadržaj L-askorbinske kiseline. Mikrobiološka analiza sušene konzumne paprike ukazala je na zadovoljavajući kvalitet svih uzoraka nakon primene predtretmana. Metod sušenja u tunelskoj sušari se pokazao kao najefikasniji za smanjenje mikrobiološke aktivnosti.
AB  - This thesis aimed to improve the functional and technological properties of dried bell and paprika peppers by applying different pretreatments and drying methods. The research included the examination of nutritional and antioxidant parameters of fresh peppers and nutritional, antioxidant, and physical parameters of the processed dried bell and paprika peppers. The influence of different pretreatments, such as blanching, chemical pretreatment, ultrasound and their combinations, was investigated. Additionally, the effect of drying methods was studied - drying in a tunnel dryer with hot air and freeze-drying. The main goal was to determine the most suitable combination of pretreatments and drying methods for the preservation of nutritional, antioxidant, and sensory properties of dried pepper. Fractional factorial designs were used to study the effects of these factors.
Within the first part of the research, the analysis of the mineral composition of commercially available fresh and processed peppers was performed, as well as the analysis of vitamin C content in four cultivars of bell peppers in three ripening stages. Dietary mineral intake and health risks assessment of toxic elements due to the consumption of pepper fruits were also evaluated. The results of these analyzes indicated that pepper fruits are not a significant source of minerals, where the amounts present in average portions for children and adults are not sufficient to meet the recommended daily needs. The exceptions were certain sour and fresh fruits, which are a significant source of Cu, Cr, and Mo. Analysis of mineral content in three ripening stages for the cultivar Kurtovska kapiya showed that the mineral content changes continuously during fruit ripening, which is reflected in higher absorption of K, Zn, Mg, Cu, B and almost constant circulation of Mg and Fe until full fruit maturity. The results of the health risk study indicated that pepper fruits and their products do not represent a health risk for children and adults due to the intake of toxic elements such as Al, Hg, Cd, and As. Most of the analyzed peppers were excellent sources of vitamin C with L-ascorbic content higher than 100 mg/100g, which means that eating 100 g of fresh pepper is enough to meet the recommended daily intake.
The second part of the study examined the effects of different pretreatments on mineral composition, total phenolics content, antioxidant activity, and L-ascorbic acid content. The first series of experiments investigated leaching of macro-, mirco- and trace elements during ultrasound pretreatment in water and acetic acid solution. The cultivar Kurtovska kapiya was used for this set of experiments. The highest leaching of elements occurred during the processing of green fruits, while ultrasonic pretreatment with acetic acid improved the extraction of toxic elements Al, Hg and As. Although ultrasonic pretreatment with acetic acid solution contributed to the highest removal of the toxic elements, it also caused a significant loss of Fe (up to 77% of total iron). The second series of experiments investigated the effects of ultrasonic, chemical, and thermal pretreatments on the total phenolics content, antioxidant activity, and L-ascorbic acid content of paprika pepper. The pretreatment temperature highly influenced the total phenolics and L-ascorbic acid content, with higher temperatures causing higher leaching of these compounds (50 and 80 oC). The applied pretreatments did not significantly affect the antioxidant activity of previously treated peppers.
The third part of the research investigated the effects of applied pretreatments and drying methods on dried paprika and bell pepper quality. For dried paprika peppers following analyses were performed: mineral composition, total phenolics content, total carotenoids content, antioxidant activity, L-ascorbic acid content, color (CIELab and non-enzymatic browning index), texture, morphological properties, and microbiological activity, while for dried bell peppers L-ascorbic acid content and microbiological activity were investigated. The aim was to determine the influence of various factors (pretreatment time, pretreatment temperature, applied additives, pH value of pretreatment solution, application of ultrasound, mass of the treated peppers, pieces size, and drying methods) on the mentioned parameters of dried pepper quality. Several factors significantly
influenced the quality of dried paprika peppers. The drying methods significantly affected total phenolics and L-ascorbic acid content, red color (parameter a*), and rehydration ratio (in the initial stages of rehydration). The pretreatment time significantly affected antioxidant activity measured by the FRAP test, L-ascorbic acid content, color parameters a*, C*, and non-enzymatic browning index. The pH value significantly affected the texture of the dried pepper. The pretreatment temperature significantly affected L-ascorbic acid content. The overall quality, studied by the desirability function, which combines all the responses for dried paprika pepper, showed that two factors have a statistically significant influence: the ultrasound pretreatment and the type of applied additive. This analysis indicated that ultrasound negatively affected the overall quality of dried paprika peppers, while potassium metabisulfite was a better additive than citric acid. The content of L-ascorbic acid of dried bell pepper was significant influence by the method of drying. Microbiological analysis of dried peppers indicated the satisfactory quality of all samples subjected to the pretreatments. The drying method in a tunnel dryer was the most effective for reducing microbiological activity.

AB  - The human health risks of cadmium (Cd), lead (Pb), and nickel
(Ni) in fifty regular and slim cigarette brands available in the
Serbian market were evaluated. Distributions on per-cigarette
basis concentrations of these metals, as determined by graphite
furnace atomic absorption spectrometry, were used as inputs in
the probabilistic risk assessment. The contents of these metals in
cigarettes varied significantly. Larger quantities of the studied
metals were observed in regular cigarettes than in slim cigarettes,
but the concentration levels per cigarette tobacco mass were
higher in slim cigarettes. The metal concentrations in counterfeit
cigarettes were marginally higher than those in authentic brands.
Based on the mean concentrations, Pb was the most abundant
toxic metal, followed by Ni and Cd. The calculated values of the
cumulative hazard index (HI) and incremental lifetime cancer risk
(ILCR) indicated a low noncarcinogenic risk and low but not negligible
carcinogenic risk from Cd, Pb, and Ni. The mean HI and ILCR
values obtained using probabilistic and deterministic approaches
were similar. A Monte Carlo simulation was employed to minimize
the uncertainty of health risk estimation. The sensitivity analysis
revealed that the most influential factor was cigarette mass followed
by Cd content.

AB  - This study investigates the effects of ultrasound, in combination with chemical pretreatments, on the quality attributes (total phenolic and carotenoid content, antioxidant activity (2,2-Diphenyl-1-picrylhydrazyl assay (DPPH)), ferric-reducing ability (FRAP), CIE L* a* b* color, non-enzymatic browning, rehydration ratio, textural and morphological properties) of red pepper subjected to drying (hot air drying or freeze drying). The fractional factorial design was used to assess the impact of factors. The global Derringer desirability function was used to determine the optimal conditions for the best quality attributes of dried pepper. The drying method influenced total phenolic content, a* (redness), and initial rehydration ratio; pretreatment time significantly affected FRAP antiradical activity, a*, chroma and non-browning index, while pH-value had a significant effect on the texture of dried pepper. Non-enzymatic browning was reduced to 72.6%, while the DPPH antioxidant capacity of freeze-dried peppers was enhanced from 4.2% to 71.9%. Ultrasonic pretreatment led to changes in the pepper morphology, while potassium metabisulfite (KMS) was a more effective additive than citric acid.

AB  - Pesticides are extensively used in the cultivation and postharvest protection of citrus fruits, therefore continuous monitoring and health risk assessments of their residues are required. This study aimed to investigate the occurrence of pesticide residues on citrus fruits and to evaluate the acute and chronic risk for adults and children. The risk ranking of twenty-three detected pesticides was carried out according to a matrix ranking scheme. Multiple residues were detected in 83% of 76 analyzed samples. In addition, 28% contained pesticides at or above maximum residue levels (MRLs). The most frequently detected pesticides were imazalil, azoxystrobin, and dimethomorph. According to the risk ranking method, imazalil was classified in the high-risk group, followed by prochloraz, chlorpyrifos, azinphos-methyl, tebufenpyrad, and fenpiroximate, which were considered to pose a medium risk. The majority of detected pesticides (74%) posed a low risk. The health risk assessment indicated that imazalil and thiabendazole contribute to acute (HQa) and chronic (HQc) dietary risk, respectively. The HQc was negligible for the general population, while the HQa of imazalil and thiabendazole exceeded the acceptable level in the worst-case scenario. Cumulative chronic/acute risk (HIc/HIa) assessment showed that chronic risk was acceptable in all samples for children and adults, while the acute risk was unacceptable in 5.3% of citrus fruits for adults and 26% of citrus fruits for children. Sensitivity analyses indicated that the ingestion rate and individual body weight were the most influential risk factors.

AB  - Solid-phase extraction (SPE) of eleven ultraviolet filters (UVFs): benzophenone-1 (BP-1); benzophenone-3 (BP-3); benzophenone-4 (BP-4); isoamyl p-methoxycinnamate (IAMC), homosalate (HMS); 4-hydroxybenzophenone (4-HB); 4-methylbenzylidene camphor (4-MBC); octocrylene (OC); octyl dimethyl-p-aminobenzoate (OD-PABA); 2-ethylhexyl-4-methoxycinnamate (EHMC); and avobenzone (AVO), has been optimized using Plackett-Burman design, Box-Behnken design, and Derrindzer desirability function. Of the six SPE variables studied, the most influencing is the type of eluent followed by pH and the methanol content in the rinsing solvent. A method with good analytical performance was obtained by applying optimal SPE conditions and liquid chromatography-tandem mass spectrometry (LC-MS/MS), with the method detection limit ranging from 0.1 to 5 ng/L, recovery from 44% to 99%, and relative standard deviation (RSD) within 19%. This method was used to analyze the content of UVFs in an urban lake (Sava Lake, Serbia). UVFs occurrence, geostatistical distribution, and associated environmental risk are highly dependent on recreational activities. The average concentrations of UVFs ranged from 0.3 to 113 ng/L, and the most present substance was EHMC, followed by 4-MBC and BP-3. The spatial distribution of the risk quotient (RQ = 0.04–1.7) inside the lake is highly correlated with the number of people bathing and swimming. Human exposure through the dermal pathway is higher than ingestion for most UVFs. Monte Carlo simulation of probabilistic risk assessment estimated the percentile P10, P50, P90 of 12.7; 17.3; 47.5 and 20.1; 27.6; 77.5 ng/kg∙day for total human exposure of adults and children, respectively. The sensitivity analysis revealed that the health risk estimate depends mostly on the content of EHMC, HMS, and 4-MBC, while the most influential exposure variables were human body weight and skin surface area. There is no serious concern to human health due to UVFs in the short term; however, a high ecological risk in some parts of the lake is estimated.

AB  - The content of twenty-one essential and toxic elements in fresh, dried, and processed peppers (Capsicum annuum) obtained from the Serbian market was analyzed. The concentration of the elements varied significantly between the analyzed samples. The most abundant essential element was K with an average concentration of 8.4 g/kg fresh weight. All processed products also had increased Na content, reaching a maximum value of 15.8 g/kg fresh weight in peppers from the pepper-meat products. Toxic elements Pb, Cd, and As were found in all analyzed samples, while Hg was detected in a few samples. Based on guideline values or recommended dietary intake, pepper and pepper products are not a significant source of essential elements. The health risk assessment was conducted by calculating target hazard quotient (THQ) and carcinogenic risk (CR), as well as comparing estimated weekly (Al, Hg, Cd) and daily intake (As, Pb) with appropriate PTWI and BMDL values. The risk assessment results indicate that peppers and pepper products are mostly safe for consumption both for adults and children. However, consumption of some pepper samples may pose a health risk due to an incremental lifetime cancer risk (ILCR) value higher than 10−4

AB  - This study collected agricultural surface soil samples from 200 sites in the district of Braničevo, located in the Carpathian Mountains – Pannonian Basin south of the Danube River (Serbia). The main objective was to determine the soil contamination by ten potentially toxic elements (As, B, Cd, Cr, Cu, Mn, Mo, Ni, Pb, Zn) and evaluate the associated ecological risk via different indices. The physicochemical parameters, pH, organic carbon, water content, and soil texture were also analyzed. The mean values of most metal concentrations remained below their corresponding national target values, except for Mo and Ni. The main soil texture types were silt loam (40.5 %) and silty clay loam (34.5 %). According to the mean values, pollution load index (PLI) and potential ecological risk (RI) demonstrated that the soil in the study area was exposed to moderate pollution and moderate ecological risk, while enrichment factor (EF), geoaccumulation index (Igeo), and contamination factor (CF) revealed very high enrichment and contamination with Mo, implying the impact of anthropogenic activities. There was a lack of strong correlations among elements and soil properties, except for Cd and Corg, while moderate to strong positive inter-metal relationships suggested their common sources. The chemometric analysis illustrated the classification of sampling sites into two distinct clusters of spatial similarities according to higher and lower metal concentrations. Geospatial mapping identified a few areas of considerable ecological risk. © 2022,Carpathian Journal of Earth and Environmental Sciences. All Rights Reserved.

AB  - The influence of extraction parameters on the ultrasonically assisted extraction (UAE) of K, Na, Ca, Mg, Zn, Cu, Fe, Mn, Cr, Se, Mo, Li, Al, B, Pb, Hg, Cd, As, and Ni was studied to determine the conditions when a minimum of essential and maximum of toxic elements is leached from peppers, depending on its ripening stage. The effect of process variables was investigated by using Box–Behnken design. Each essential element had a different optimal condition for minimal leaching, while the toxic elements were predominantly extracted with acetic acid solution as extractant. The highest correlation between extraction conditions and concentration of extracted elements was found for aqueous extracts of mature green pepper. The concentration of acetic acid highly influenced the leaching of elements and a strong correlation between the concentration of Al, B, Fe, and Mn, and the UAE experimental conditions were observed. Practical applications: This study investigates the leaching of minerals and heavy metals present in vegetables to the most commonly used media (water and acetic acid) during processing and canning. The data from this study may be useful for improving the quality of processed pepper products due to new information on how different parameters influence these losses (ripening stage of peppers, medium/solvent used for preparation, or storage, applied temperatures, time, mass to volume ratio). Essential elements are better preserved during the processing of intermediate breaker and mature red pepper compared to green mature fruits. Better retention of essential elements in the breaker and mature red pepper (that are mostly used in industrial processing) can be achieved by reducing the contact time with water, as well as mass to volume ratio. Leaching of toxic elements Al, Hg, and As can be improved with an acetic acid solution.

AB  - Drying is one of the methods for the preservation of fruits and vegetables [1]. Peppers are still
dried in open sunlight, although this method has many shortcomings (long drying time,
microbial contamination, depending on weather conditions, final product of poor color) [2].
Deterioration of numerous nutrients, which occurs during drying, can be prevented by
applying various pre-treatments and/or different drying methods [2–4]. The aim of this study
was to investigate effects of different pretreatments and drying methods on L-ascorbic acid
(L-AA) content in dried bell pepper. Effect of following parameters were studied: applied
additive (0.25% citric acid, 0.25% potassium metabisulfite or their mixture), temperature,
time, pH value of pretreatment solution, ultrasound pretreatment, pepper slices size, pepper
mass and drying method (hot air-drying and freeze-drying). For organization of experiments
fractional factorial design was used. Results showed that only the drying method significantly
affects the content of L-AA after a month of storage. Freeze-drying was a better method for
L-AA preservation. The interaction between the drying method and the size of pepper slices
was also meaningful, although this interaction wasn’t statistically significant. Better
preservation of L-AA, for hot air-dried samples, was achieved with a slices size of 4×4 cm
compared to smaller (2×2 cm) and larger ones (8×8 cm). In the case of freeze-dried samples,
the slice size didn’t affect the preservation of L-AA. The medium slices of the pepper fruit
provided better penetration of the additives, which resulted in a better protective effect on
L-AA during the hot air-drying. On the other hand, smaller pieces (2×2 cm) led to higher
losses, probably due to the higher leaching of L-AA. Larger slices (8×8 cm) proved to be the
most unfavorable for the preservation of L-AA (maybe due to less diffusion of additive during
pretreatment and its later weak effect during drying).

AB  - Soil samples collected from two districts of southern Serbia, Pčinja and Jablanica, were
analyzed in order to determine the content of eleven heavy metals and metalloids (As, B,
Cd, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Zn). The concentration of the elements was measured by
atomic absorption spectrometry in 152 samples collected from agricultural land. The main
goal was to assess the environmental and health risk of eleven heavy metals and metalloids
tested in the soil. To determine the degree of soil contamination, measured concentrations
were compared with limits and remediation values given in the Serbian Rulebook. It was
determined that the average content of tested elements in mg/kg was: As (12.76), B
(113.73), Cd (1.10), Cr (58.01), Cu (29.62), Hg (0.33), Mn (1067.89), Mo (0.21), Ni
(34.85), Pb (233.38), Zn (64.49). The average content of all examined trace elements in
soil did not exceed the remediation values. However, the average content of Cd, Hg, Pb
exceeded the limit values. Five pollution indices were used to assess environmental risk:
enrichment factor (EF), geoaccumulation index (Igeo), contamination factor (CF),
pollution load index (PLI), and potential environmental risk index (RI). Based on EF and
Igeo, it was concluded that the biggest problem was As, Hg and Pb. More than half of the
samples are moderately contaminated with Pb, over 30% of samples are heavily
contaminated with Hg, while some samples were highly polluted with As. Contamination
factor, as well as PLI and RI, showed moderate contamination of the soil with Hg and Cd.
The health risk assessment was estimated by hazard index (HI) and the carcinogenic risk
index (CR), which determine the non-carcinogenic and carcinogenic effects that heavy
metals can cause in the human body, throught ingestion, inhalation and dermal contact
with contaminated soil. This study showed that there was no non-carcinogenic risk as
adults-hazard index (HI) calculated for each sample was less than one. On the other hand,
there was a higher risk for children's health since over 85% of soil samples had HI values
greater than one. Combine carcinogenic risk of all elements was estimated with lifetime
carcinogenic risk (LCR). There is no risk of developing cancer in both groups because
more than 90% of the samples had acceptable carcinogenic risk values between 1,0*10-6
i 1,0*10-4, while a small number had concern LCR values grater than 1,0*10-4.

AB  - Red pepper (Capsicum annum) fruits contain high amount of ascorbic acid (vitamin C), which is of great importance for human health. The aim of this study was to found how various pretreatments and drying methods influence on retention of ascorbic acid in dried pepper. The cultivar “Horgoška sweet 6”, often used for the production of paprika, was selected for analysis. Five sets of experiments were performed to investigate the effect of the following parameters: pretreatment temperature (20 oC, 50 oC, 80 oC), pH value (3, 6.5, 10), additive (0.25% citric acid, 0.25 % potassium metabisulfite and 0.25 % citric acid + 0.25 % potassium metabisulfite), ultrasound (off and on) and drying method (hot air drying and freeze drying). The initial content of ascorbic acid in fresh pepper was 292 mg/100 g dry basis (d.b.) and it was reduced after all pretreatment and after drying of pretreated samples. Most of examined pre-drying treatments improve retention of ascorbic acid in final dried peppers, except treatments at 80 oC. Our results indicate that temperature and drying method were parameters that significantly influenced ascorbic acid content in dried peppers. Other parameters were not significant, but had a certain effect on retention of ascorbic acid. The best parameters were temperature 20 oC, pH 6.5, citric acid/potassium metabisulfite, without applying ultrasound including freeze drying method.

AB  - The aim of this study was to evaluate mineral composition of two commonly cultivated pepper varieties from Serbia (cultivars Kalifornijska and Slonovo uvo), at three ripening stages. Concentration of macro (K, Ca, Mg, Na) and micro elements (Zn, Fe, Mn, Cu, B, Cr, Mo, Se, Li, Al), and heavy metals (Pb, Hg, Cd, As, Ni) was determined, using AAS and ICP-MS, after microwave-assisted digestion. Relative standard deviations of AAS and ICP-MS measurements, for the most of analyzed elements, were between 0.08 - 9.28 %, indicating that precision was satisfactory. Potassium was the most abundant element in all samples, followed by Mg and Ca. Among the investigated micro elements the average content of zinc was the highest, followed by iron, for most of analyzed samples. Zinc and iron were followed by copper, manganese and boron. Semi-mature peppers of cultivar Kalifornijska were richer in K, Ca, Mg, Fe and Zn compared to other maturity stages. For cultivar Slonovo uvo results were different compared to cultivar Kalifornijska. The content of K and Ni increased with ripening of fruit, while the content of magnesium decreased with ripening of fruit, which was not case for cultivar Kalifornijska. The higher values of Mg, Fe, Zn; lower values of Ca and higher values of Cu in cultivar Slonovo uvo were reported by different authors for other pepper varieties.

AB  - Prisustvo farmaceutskih preparata i opojnih droga u otpadnim, površinskim i podzemnim vodama
predstavlja ozbiljan problem po zdravlje ljudi. Razlog za to je činjenica da ova jedinjenja poseduju
biološku aktivnost, lako su mobilna, neka od njih imaju sposobnost bioakumulacije, a mnoga su i
teško biorazgradiva. Dosadašnja istraživanja ukazuju da su glavni izvor farmaceutskih preparata u
vodi, komunalne otpadne vode poreklom iz domaćinstava, bolnica i industrije. Farmaceutski
preparati koji se javljaju u vodama su: analgetici i antiinflamantorna jedinjenja, antibiotici, β-
blokatori, hormoni, regulatori lipida, citostatici, kontrastna sredstva, opojne droge, denzifekciona
sredstva. U sastav proizvoda za ličnu higijenu i kozmetiku ulaze jedinjenja koja poseduju
sposobnost bioakumulacije, a mnoga pokazuju estrogene i endokrine efekte.
Ispitivanja otpadnih voda u gradovima Zapadnog Balkana ukazuju da se opojne droge najviše
konzumiraju u Zagrebu, Beogradu i Novom Sadu (kokain, amfetamin i MDMA). Zapažen je trend
pojačanog korišćenja opojnih droga vikendom u proseku 10-20%. Glavni procesi koji određuju
njihovu sudbinu u vodenim sredinama su biotransformacija, sorpcija, hemijska transformacija,
fototransformacija i isparavanje.
AB  - The presence of pharmaceuticals and narcotic drugs in waste, surface and groundwater presents
a serious problem for human health. The reason for this is the fact that these compounds possess
biological activity, they have easy mobility, some of them have the ability to bioaccumulation and
many are heavily biodegradable. So far, researches have shown that the main source for
pharmaceutical preparations in water are municipal waste water with origin from households,
hospitals and industry. The main drugs which appear in waters are: analgesics and antiinflammatory
compounds, antibiotics, β-blockers, hormones, lipid regulators, cytostatics, contrast
remedy, drugs and disinfection remedies. The composition of products for personal hygiene and
cosmetics includes compounds that possess the ability of bioaccumulation, where many of them
show estrogen and endocrine effects.
Examination of waste waters in Western Balkan cities indicate that drugs are mostly consumed in
Zagreb, Belgrade and Novi Sad (cocaine, amphetamine and MDMA). A trend of increasing drug
usage on weekends was observed on average of 10-20%. Main processes that determine future
usage of drugs in water environments are biotransformation, sorption, chemical transformation,
phototransformation and evaporation.
