Abstract
Toxic elements, lead, and copper are often found in wastewater discharged from industries such as mining. The discharge of untreated effluent poses severe environmental challenges and sorption methods using agricultural waste materials are proposed as an efficient and cost-effective solution. For this research, activated sunflower material (ASM) was prepared from abundantly available agricultural sunflower waste residues and utilised to remove Pb2+ and Cu2+ ions from an aqueous medium. To begin, we examine variables that may have an impact on the adsorption process, such as pH, contact time, adsorbent dose, and initial concentration using Box-Behnken Design (BBD) to find optimal conditions. Maximum removal efficiency was found at a pH of 5, contact time of 180 min, and initial concentration of 50 mg/L for Pb2+ and 150 mg/L for Cu2+. Additionally, adsorbent dose differed by element, for Cu2+ it was 200 mg, whilst for Pb2+ it was 124 mg. Features of activated carbon such as morphology, elemental composition, textural properties, and surface functionalities were characterised using SEM-EDS, BET, FTIR, and XPS. The adsorption equilibrium data were analysed by Langmuir, Freundlich, and Dubinin-Radushkevich isotherm models. It was found that the obtained results for Pb2+ adsorption were better described with the Freundlich isotherm model. Maximum adsorption capacities for Pb2+ and Cu2+ were 91.8 mg/g and 20.5 mg/g, respectively. Furthermore, kinetic studies confirmed that the adsorption process followed a pseudo-first-order kinetic model for Pb2+, but for Cu2+ all applied kinetic models fitted experimental data with the same values of the correlation coefficient (R2 = 0.99). After comprehensive analysis using the methods mentioned above, ASM was tested for the removal of Cu2+ from mining wastewater sample, and the obtained removal efficiency was 98.6% ± 2.0%. The results of desorption experiments conducted, confirm that ASM has good potential to be reused for the purpose of removing Cu2+ from wastewater.

Abstract
African swine fever (ASF) has been detected in many European countries since its introduction in Georgia in 2007. Serbia suffered its first case of ASF in the domestic pig population in 2019. At the beginning of 2020, ASF was detected in wild boars in open hunting grounds in the southeastern region of the country in districts along the country's borders with Romania and Bulgaria. Since then, all ASF outbreaks in wild boar were clustered in the population located in the same bordering areas. Despite the newly implemented biosecurity protocols for hunters in 2019, ASF was detected for the first time in June 2021 in the wild boar population located in an enclosed hunting ground in the northeast region of the country. In this study, we reported the first ASF outbreak in a wild boar population located in an enclosed hunting ground in close proximity to the Serbian-Romanian border. The epizootiological data on the field investigation of the ASF outbreak, with descriptions of the clinical signs and gross pathological lesions detected, including the total number as well as the estimated age, sex, and postmortem interval, were analyzed. Clinical signs were detected only in nine diseased wild boars, while in total, 149 carcasses were found in the open and enclosed part of the hunting ground. In addition, 99 carcasses from which samples (parts of spleen or long bones) were collected for molecular diagnostics (RT-PCR) were confirmed as ASF-positive. The results of the epidemiological investigations indicate the central role of wild boar movements as well as the constant risk of human-related activities in the countries bordering area.

Abstract
Oxidative stress, arising from disrupted balance between reactive oxygen/nitrogen species (ROS/RNS) and antioxidant defences, has been implicated in the pathogenesis of stress-related disorders. There is a growing body of evidence that supports the relationship between the activity of the hypothalamic-pituitary-adrenal (HPA) stress system, oxidative stress and magnesium (Mg) homeostasis. The present study aimed to explore the gap in our current understanding of antigenotoxic and protective effects of Mg supplementation against excessive ROS production in male rats during chronic treatment with adrenocorticotropic hormone (ACTH). Our findings show that exposure to exogenous ACTH (10 μg/day, s.c., for 21 days), as one of the key mediators of the HPA axis and stress response, produced an increase in superoxide anion levels and a decrease in superoxide dismutase activity in plasma. We observed that Mg supplementation, starting seven days prior to ACTH treatment and lasting 28 days (300 mg/L of drinking water, per os), abolished these effects in experimental animals. Moreover, our study reveals that ACTH increased the susceptibility of peripheral blood lymphocytes to ex vivo H2O2-induced total and high-level oxidative DNA damage, while Mg completely reversed these effects. Collectively, these results highlight the promising role of Mg in stress-related conditions accompanied by increased oxidative stress in animals and support further investigation using human dietary trials.

Abstract
The heavy metals content (HMs) was investigated in 14 different medicinal plants collected from the three regions in Central Serbia, Zlatar, Sokobanja, and Kopaonik. The concentrations of Cd, Cr, Ni, Hg and Pb were determined: Cd (<0.03-2.72 mg/kg); Cr (<0.08-12.1 mg/kg); Ni (<0.08-12.2 mg/kg); Pb (0.6-49.0 mg/kg); the Hg concentration was below the detection limit of 0.06 mg/kg in all samples. The daily intake of HMs due to ingestion of 200 mL of herbal infusion was in all cases below the recommended limit prescribed by the World Health Organization. The estimated daily intake values were below the values for the oral reference dose regulated by the U.S. Environmental Protection Agency (USA EPA). The target hazard quotient and hazard index for Cd, Cr Ni, and Pb were below 1. Nevertheless, due to the tendency of heavy metals to accumulate in the organism, attention should be paid to the daily intake of herbal infusion during long-term usage. Specifically, it is recommended to consume not more than one cup (200 mL) of infusion per day made from thyme (Mt. Zlatar) and blueberry (Mt. Kopaonik), and not more than two cups per day for other herbs.

Abstract
BACKGROUND Emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus) could lead to an increase in dental anxiety, avoidance of dental visits, and general neglect of oral health. This online questionnaire-based study conducted in April and May of 2021 in Serbia aimed to determine the impact of the coronavirus disease 2019 (COVID-19) pandemic on dental care. MATERIAL AND METHODS The study included 2060 adult citizens of the Republic of Serbia who participated in an anonymous online questionnaire based on a 5-point Likert scale. Data were collected on dental care routine prior to and during the pandemic, and the fear of negative consequences for oral health. The results were statistically analyzed using descriptive statistics, Pearson's correlation coefficient, ANOVA, and the paired t test. RESULTS Approximately one-fifth of the respondents postponed dental visits during the pandemic. Concern about postponing dental treatment was expressed by more than one-half of the respondents (57.1%), while 21.4% thought that they were already experiencing the consequences. Avoidance of preventive examinations and improvement of oral hygiene are more common among the elderly compared to younger respondents (P=.000). CONCLUSIONS The COVID-19 pandemic did not significantly affect the habit of avoiding dental interventions due to fear, but it did lead to part of the population completely avoiding even urgent dental interventions during the peak of the pandemic, and opting for tooth extraction rather than treatment. The strongest impact on dental care in the pandemic was among people over 64 years old.

Abstract
African swine fever (ASF) is currently the most important challenge for domestic pig production worldwide. The virus reached Eurasia in 2007, and is today affecting more than half of European Union member countries. Among Western Balkan countries, Serbia suffered the first case of ASF in a backyard holding in 2019. Since then, numerous outbreaks in domestic pigs and wild boar have been reported throughout the country despite the efforts of the veterinary authorities to control the disease. The lack of an effective vaccine is one of the main constraints, and the only currently available option to prevent further ASF infections is the application of strict biosecurity measures. Regarding biosecurity, backyard pig producers and smallholding farmers in Serbia have substantial gaps in the knowledge and fail to comply with safe production behaviour that favours the spread of ASF virus. In the currently prevailing smallholder and backyards farming systems, farm biosecurity is largely non-existent. The aim of this review was to identify specific ASF-risks factors in the current pig production system and gaps in biosecurity measures related to the human activities recognised as social and cultural identity in Serbia. Moreover, the main risk factors for ASF spreading and transmission at the domestic/wild boar interface, biosecurity practices in different production systems, and possible future control measures and awareness campaigns are discussed.

Abstract
A calcium-pyro-hydrochar (Ca-PHC) can be distinguished as a novel sorbent of Pb2+ and Cd2+ from an aqueous solution. It was obtained using hydrothermal treatment of the spent mushroom substrate (SMS), followed by a CaCl2·5H2O activation and pyrolysis. The characterisation of chars before and after modifications was done by scanning electron microscope (SEM), Brunauer-Emmett-Teller (BET) and Fourier transform infrared (FTIR). Batch experiments were performed to examine Ca-PHC's sorption properties and binding mechanisms to selected metal ions. The maximum sorption capacities of Ca-PHC for Pb2+ and Cd2+ were 297 mg g-1, and 131 mg g-1, respectively. The obtained results demonstrated that the sorption of Pb2+ and Cd2+ by Ca-PHC follows a pseudo-second kinetic model and Freundlich isotherm. The binding of the selected metals onto Ca-PHC was enabled by the ion-exchange mechanism, surface complexation, mineral precipitation and cation-π interaction. Thermodynamic parameters indicate that metal ions binding by Ca-PHC are spontaneous and endothermic. Due to the high adsorption capacities, the obtained Ca-PHC has good potential for application in industrial wastewater treatment. In addition, the demonstrated use of SMS highlights another possibility of applying this specific biomass relevant to sustainable and economical waste management in the growing mushroom industry.

Abstract
All remediation pathways in aqueous solutions come down to three dominant ones - physical, chemical, and combinations thereof. Materials proposed for adsorption and oxidative degradation can induce positive or negative effects on cells compared to the pollutants themselves. Present research deals with the effects different methods for pesticide remediation have and how they impact cytotoxicity. With this particular intention, Fe-modified zeolites (obtained via citrate/oxalate complexes) of three zeotypes (MFI, BEA and FAU) were prepared and tested as adsorbents and Fenton catalysts for the removal of the acetamiprid pesticide. The materials are characterized by AFM, FTIR spectroscopy and ICP-OES. A different effect of the zeolite framework and modification route was found among the samples, which leads to pronounced adsorption (FAU), efficient Fenton degradation (MFI) or synergistic effect of both mechanisms (BEA). The cytotoxic effects of acetamiprid in the presence of zeolites, in pristine and modified forms, were tested on the MRC-5 human fibroblast cell line. A complete survey of the toxicity effect behind different pesticide removal methods is presented. Since neither adsorption nor catalytic degradation is the best option for pesticide removal, the focus is shifted to a combination of these methods, which proved to be optimal for pesticide toxicity reduction.

Abstract
Dehydration of the edible seaweed Chondrus crispus was performed by freeze-drying, conventional oven-drying and emerging microwave hydrodiffusion and gravity (MHG). In this work, the drying kinetics and modelling, estimating specific energy consumption and environmental impact of distinct processes were tested. Color and microstructural features of the dried macroalgae were also evaluated, as well as their nutritive characterization, chemical profile and bioactive potential (antioxidant and antimicrobial activities). Moreover, collected liquid phases from both the defrosted and MHG treated samples were also characterized. All methodologies provided solid phases with an adequate final moisture content. MHG significantly reduced the needed time, specific energy consumption and environmental impact, providing C. crispus with intermediate color and histological structure characteristics. Overall, this trend was also defined to tested chemical parameters and bioactivities. MHG provided aqueous extracts with potential bioactive compounds from this red alga, increasing the efficiency of this drying method.

Abstract
Background Fear has always been closely linked to dentistry but it could be intensified by the objective risks imposed by the pandemic. The objective of this study was to determine the profile of the frightened dental patient during the COVID-19 pandemic and determine measures taken by dentists to reduce fear and increase security among their patients. Material/Methods An anonymous online survey was conducted between March 15 and April 15, 2021. The respondents were 2060 adult citizens of the Republic of Serbia. In addition to demographic data, data related to the COVID-19 pandemic, dental fear, and attitudes and fear of dental interventions during the ongoing pandemic were compiled. The data were analyzed using descriptive statistics: the chi-square test and Pearson’s coefficient. Results Seventy percent of the respondents felt some level of fear of the ongoing pandemic, 50% felt fear of going to a dentist during the pandemic, 20% considered a dental office a hotspot for the transmission of SARS-CoV-2, and 43% would visit their dentist only in the case of emergency. Conclusions The COVID-19 pandemic has affected the attitudes and behavior of people pertaining to visits to dental offices. Identifying frightened patients and their opinions and fears at this challenging time would make it easier for dentists to include protocols in their everyday practice to increase a sense of security among their patients, such as implementing preventive measures in front of the patients, ensuring an empty waiting room, and providing telephone consultations.

Abstract
OBJECTIVE Positron emission tomography/computed tomography using fluorine-18 fluoro-deoxyglucose (18F-FDG PET/CT) is not routinely used for diagnosis of testicular carcinoma. Unlike CT which cannot confirm with certainty the nature of the lesions, especially in post-therapy setting, 18F-FDG PET/CT detects active disease by showing increased glucose metabolism within the lesions. AIM Determination of 18F-FDG PET/CT usefulness in detection of seminoma, therapy response evaluation and comparison to CT findings and tumor marker levels. MATERIAL AND METHODS Eighty-two men (age 39.8±10.1) after orchiectomy and histopathological confirmation of seminoma were included in this study. Indications for 18F-FDG PET/CT were initial staging, restaging after chemo/radiotherapy with positive/uncertain CT, suspected recurrence on CT, elevated tumor markers. All patients had clinical follow-up of up to 8 years (median 33.5) after the first 18F-FDG PET/CT examination. Degree of metabolic activity was analyzed visually and semi-quantitatively using maximum standardized uptake value(SUVmax). RESULTS Fluorine-18-FDG PET/CT was true positive in 36 patients (43.9%) with average SUVmax of 7.9±4.8.Recurrence was mostly found in retroperitoneal lymph nodes and distant metastases in lungs, bones, liver. Six findings were false positive and 3 false negative. Sensitivity, specificity, accuracy of 18F-FDG PET/CT were 92.3%, 86.0%, 89.0% and of CT 60.8%, 66.6%, 63.4%. Pearson Chi-square test showed statistically significant difference between the results of 18F-FDG PET/CT and CT (P=0.016). Significant correlation was found between positive 18F-FDG PET/CT findings and levels of LDH (P=0.043), while non-significant between AFP, β-hCG (P>0.05). CONCLUSION Fluorine-18-FDG PET/CT was superior to CT in evaluation of therapy response, active disease in residual tissue and normal size lymph nodes, as well as when CT was negative and tumor markers were elevated. Elevated lactate dehydrogenase (LDH) contributes to positive 18F-FDG PET/CT findings.

Abstract
Nosemosis is a bee disease practically present in all countries of the world. Control of the presence of Nosema apis and Nosema ceranae is of great importance. The consequences for bees will depend on the degree of infection of the bees colony.Weakening of bee colonies, reduction of production possibilities, contamination with bee feces of hives, death of bees and / or their complete disappearance are some of the signs of the disease. The bees life physiology, which largely depends on the season, and regular control of the pathogenspresence can determine the perspective of the disease.
The consequences of reducing the number of bee colonies are not only reflected in a smaller amount of bee products (honey, royal jelly, pollen, wax), but their lack is directly reflected in agricultural production by reducing pollination. Domestic and international trade in bee products plays an important role in the transmission of Nosema sp. and others infectious and parasitic diseases of bees. Therefore, the control of the presence and viability of Nosema sp. in some bee products is important. Our analysis showed that the control of the presence of the cause of nosemosis in our conditions is small in relation to the number of beekeepers, bee colonies and hives. On the other hand, reducing the viability of Nosema sp. in different temperature conditions provides an opportunity for safe trade.

Abstract
In this pilot study, a method for the determination of phthalates in honey was developed. The following phthalates are included: diethyl phthalate, di-isobutyl phthalate, di-n-butyl phthalate, bis (2-Ethylhexyl) phthalate, and di- (n-octyl) phthalate. For the preparation of the samples, the method of liquid-liquid extraction with hexane with an ultrasonic bath was used. The analysis of the prepared samples was performed using gas chromatography and a mass detector. The method is reliable, sensitive, and reproducible with a detection limit of 0.28 - 1.38 ug/kg. This paper presents the results of testing samples of honey stored in glass and plastic packaging for three years in order to determine the migration of phthalates. Dimethyl phthalate was not found in the tested samples. Diethyl phthalate in glass samples from glass packaging was below the LOQ, and it ranged from 2.1 to 4.11 µg / kg in the samples of honey in plastic packaging. The values of di-isobutyl phthalate, di-n-butyl phthalate and bis (2-ethylhexyl) phthalate ranged between 5.32 and 22.60 µg / kg respectively;1.32 – 27.80 µg/kg; 4.45-19.19 µg/kg; di-(n-octyl) phthalate and di-methyl phthalate were < LOQ

Abstract
American foulbrood (AFB) is one of the most important contagious honey bee diseases. In Serbia, it is mandatory to report AFB, and this disease is registered in our country every year. Starting from 2018, active surveillance of the presence of the AFB has been conducted throughout the country. The paper analyzes the data on the occurrence of AFB during the period between 2019 and 2021 from official disease reports in the National Animal Disease Notification System "VetUp". The results of this research indicate that AFB appears every year in the Republic of Serbia, despite the measures that are being applied. The results indicate that in 36 settlements in the country, this disease has reoccurred in the same localities in the observed period. Namely, in 17 localities AFB occurred consecutively in the 2019-2020 period , while in 21 localities the disease was re-registered consecutively in the period between 2020 and 2021 (until 6.11.2021), and it reoccurred in 2021 in 9 localities, compared to the registered cases of AFB in 2019. It was found that the disease has consecutively been reoccurring in 5 location between 2019 and 2021 in the same locations. The fact that the disease has been occurring for several years in the same places speaks in favor of the fact that the control measures applied in the control of this disease are not effective enough. Continuing education of beekeepers, veterinarians and veterinary inspection in the field of diagnosis and effective decontamination and neutralization of all potencional sources of AFB reinfections, revision of current legislation, as well as raising awareness of the importance of early diagnosis of as many cases of this disease as possible are the key factors in successful AFB control.

Abstract
Micro-sized multivesicular liposomes were prepared, radiolabeled with 177Lu, and tested in vitro and in vivo to evaluate the potential of 177Lu-labeled micro liposomes in radiosynoviorthesis (RSO) therapy. A standard reverse-phase procedure of liposome preparation with a lipid mixture of DPPC: CHOL (80:20%) was used for the synthesis. TEM and fluorescence microscopy imaging were performed to determine the size, shape, and structure of the prepared liposomes. Both measurements are in good agreement while TEM micrographs additionally indicate to a large multivesicular inner structure of prepared liposomes. A simple and straightforward procedure was used for liposome radiolabeling with 177Lu, a well-known and commonly used radionuclide in radiotherapy with favorable properties, that can be exploited in RSO therapy. Radiolabeled 177Lu-liposomes were tested in vitro for stability and then injected into the knee joints of Wistar rats where liposome in vivo behavior was followed up to 30 days post injection. Results from both ex vivo biodistribution and in vivo imaging studies presented a high stability and retention (>94 %ID) of 177Lu-micro liposomes in the synovial liquid for the entire observation period. Leakage of free 177Lu or 177Lu-liposomes from the synovial fluid has not been detected, indicating to a possible application of 177Lu-liposomes in radiosynoviorthesis (RSO) therapy.

Abstract
In the framework of bio-circular economy, miscanthus biomass was valorized through a single-stage, low severity hydrothermal carbonization process. The produced hydrochars were characterized using elemental and spectroscopic methodologies. It was determined that as the temperature increased so did the C content (47.9 and 68.9% for the samples prepared at 180 and 260 °C, respectively), whereas the O content decreased (from 44.2 to 25.5%, respectively). The adsorption behaviour of the hydrochars was investigated in the adsorption of Cu2+ and NH4+ and MIS-180 was determined as the optimum sample, achieving qmax values of 310 and 71 mg g-1, respectively. Isotherm and kinetic analysis indicated the higher number of O-containing functional groups of MIS-180 as the main reason for its higher adsorption capacities. Furthermore, Cu2+ adsorption followed the 2nd-order kinetic model, whereas NH4+ adsorption followed the 1st-order kinetic model, due to the different mechanisms involved, inner-sphere and outer-sphere complex formation, respectively.

Abstract
The objective of this study was to analyse the content of OHCs and NDL-PCBs in wild boar population living in densely populated flatland region with intensive agricultural production. A total of 82 liver samples were analysed by GC-MS method, revealing the presence of minimum one residue in the liver of the majority of animals (92.7%). Most commonly detected residues included ∑ HCH (64.6%), ∑endrin (56.1%) and ∑dieldrin (32.3%). Mean concentrations were in the range ∑endrin > ∑dieldrin > ∑HCH > ∑NDL-PCB > ∑DDT > ∑CHL > ∑endosulfan > methoxychlor. The dominant compound within the total content of NDL-PCBs was PCB 153 (76%). The assessment of daily intake and determination of Health Index indicated that in 6.1% of the samples the consumption of one single portion of wild boar liver would be harmful to human health due to the presence of ∑endrin or NDL-PCBs.

Abstract
As an inert radioactive gas, 222Rn could be easily transported to the atmosphere via emanation, migration, or exhalation. Research measurements pointed out that 222Rn activity concentration changes during the winter and summer months, as well as during wet and dry season periods. Changes in radon concentration can affect the atmospheric electric field. At the boundary layer near the ground, short-lived daughters of 222Rn can be used as natural tracers in the atmosphere. In this work, factors controlling 222Rn pathways in the environment and its levels in soil gas and outdoor air are summarized. 222Rn has a short half-life of 3.82 days, but the dose rate due to radon and its radioactive progeny could be significant to the living beings. Epidemiological studies on humans pointed out that up to 14% of lung cancers are induced by exposure to low and moderate concentrations of radon. Animals that breed in ground holes have been exposed to the higher doses due to radiation present in soil air. During the years, different dose-effect models are developed for risk assessment on human and non-human biota. In this work are reviewed research results of 222Rn exposure of human and non-human biota.

Abstract
Modern livestock production inevitably involves the use of antimicrobial drugs. Adequate application thereof depends on the application of appropriate biosafety measures as well as timely and accurate diagnostics of the diseases. Administration of antimicrobial drugs without previous identification of “zootechnical errors” or relevant laboratory analysis may lead to the development of antimicrobial resistance (AMR). Surveillance and monitoring of AMR is conducted according to prescribed procedures and includes sampling at slaughter line. Quite often, such procedures are missed out during production cycle, which results in an inadequate use of antibiotics and consequent development of antimicrobial resistance and resistance gene transfer. In this research, we monitored the presence of specific bacterial species from the family Enterobacteriaceae and their sensitivity to particular antibiotics in diverse animal categories at pig farms over the breeding period. The aim of the study was to establish the following: development of antimicrobial resistance by isolated bacteria, occurrence of the resistance towards several diverse groups of antibiotics, and possible alternatives to antibiotics in cases when therapy is required. The research confirmed the development of AMR during pig production process, which is often manifested as multiple resistance (group of penicillin and synthetic penicillin drugs, aminoglycosides, fluoroquinolones, tetracyclines).

Abstract
The pig production is considered to be amongst the animal husbandry sectors with the highest antimicrobial usage. In Serbia, antimicrobials have wide application at pig farms as therapeutic but also as a prophylactic treatment. The aim of the research study was assessment of the antimicrobial usage in different stages of pig production in commercial farrow to-finish pig holdings located in Vojvodina Province (Serbia). In the research a total eleven pig holdings located in the Vojvodina Province were included. All investigated herds were single site farrow-to-finish production systems with minimum of 300 sows in the site. The data on prophylactic and therapeutic measures on the investigated farms were obtained from official farm treatment records provided by the veterinarians and/or farmers. The antimicrobials usage on the pig farms was recorded by product, administration route and animal production category. Analysis of recorded data revealed that different types of antimicrobials from almost all groups are applied. Breeding pigs (sows, boars) received less treatment compared to growing categories. Regarding different antimicrobials, a frequent use of cephalosporins and polymyxins applied to growing piglets was detected. The group treatments were mostly preventive and antimicrobial usage often lack prior a precise diagnosis. The high amounts of macrolides and pleuromutilins (tiamulin), quite often in combination with tetracycline’s in fattening stage were notified. In conclusion, the significant level of prophylactic antimicrobial treatments in farrow-to-finish pig farms in Serbia is evident. The present study was initiated as a first step for comparing antimicrobial usage on herd level using available data.

Abstract
This work investigates the transport behaviour of selected organophosphorus pesticides, OPPs (chlorpyrifos, CP; chlorpyrifos-methyl, CPM; chlorfenvinphos, CF) through Danube alluvial sediment in the presence of hydrochars and biochars. The investigated hydrochar, obtained at three different temperatures (180 °C, 200 °Cand 220 °C), originated from sugar beet shreds (SBS) and Miscanthus×giganteus (MIS). Results are described by conventional advective-dispersive equation (ADE). Retardation coefficients (Rd) for all OPPs were in the range 6.2-16. Biodegradation was 4.15 and 1.80 for CPM and CP, respectively, while for CF biodegradation did not occur. The addition of carbon rich materials increases retardation of all OPPs in the range from 4 to 18 times depending on the material. Column experiment results indicated that biodegradation of OPPs occurred (up to λ = 13). In order to confirm that biodegradation occurred in the column experiments, we isolated OPPs degrading microorganisms for the first time from the alluvial sediment. A strain capable of degrading CP and CPM was isolated and identified as Bacillus megaterium BD5 based on biochemical properties, MALDI TOF and 16S rRNA analysis (99.54% identity). The results demonstrate that hydrochars, biochars and isolated degrading bacteria may be effective agents for reducing the mobility of or removing OPPs in contaminated soils or sediments.

Abstract
Radioactive materials released during the two most serious nuclear accidents in history, at Chernobyl and Fukushima, caused exceptionally significant contamination and perturbations of the environment. Among them, this paper focuses on the effects related to the atmospheric electricity (AE). Measurements of the most significant disturbances in the values of various AE parameters recorded near ground level are reviewed and the corresponding results are jointly evaluated. The Chernobyl and Fukushima events caused changes in the AE parameters both after long-distance transport (Chernobyl) and short-distance transport including re-suspension (Fukushima). The data indicates that the electrical conductivity of the air is more sensitive to the presence of airborne radioactivity than the atmospheric electric potential gradient (PG). PG, on the other hand, can be monitored more easily and its variation also reflects the vertical redistribution of radionuclides in the air due to their transport, deposition, and re-suspension from the ground. A brief overview of studies on atmospheric transport and deposition of radioactive clouds is given to facilitate the importance of considering the AE measurements in these subjects, and to incorporate those studies in interpreting the results of AE measurements. The AE measurements are particularly important in studying microphysical effects of enhanced radioactivity in the air where no other distance monitoring method exists, both for fair weather conditions wet conditions.

Abstract
In the Northern part of Serbia, which is part of Pannonian Basin, mute swan (Cygnus olor) population has notably increased over the last few decades. Like other birds from Anatidae family, mute swans are a host of numerous endoparasite species. The aim of this study was to acquire the data on identification and prevalence of endoparasites in mute swans in the Republic of Serbia, as that information is lacking. Individual faecal samples of sixty-eight adult mute swans were examined for the presence of endoparasites. Coprological examination was performed using flotation and sedimentation technique with saturated ZnSO4 solution. The samples were collected from December 2016 to March 2017, during epizootic of highly pathogenic avian influenza H5N8 in the Republic of Serbia. Dead mute swans were collected from twelve different locations in the Northern part of Serbia. Altogether, 39.7% of the examined fecal samples contained different parasites. The endoparasitic fauna was divers and included 3 species of nematodes, 2 cestodes species, one trematode and one protozoan species. Nematodes were the most prevalent helminthes and among these the most frequent nematode species found was Heterakis dispar (17.6%), followed by Echinuria uncinata (5,8%) and Ascaridia spp. (4,4%). Four mixed infections were found, where double infection was the most prevalent. No endoparasites were found in faecal samples of mute swans collected from the locations Sombor and Titel. As this study covers a small population of mute swans, more detailed studies need to be carried out on a larger population in order to gain an insight into the diversity and prevalence of endoparasites in the Republic of Serbia.

Abstract
Th ermophilic Campylobacter spp. are the leading cause of zoonotic enteric disease in Europe and USA. In Serbia, it has an upward trend in human population. Th e disease is usually indirectly transmitted to humans through the consumption of food contaminated by the faeces of infected animals. Th e aim of this paper was to analyze data on the prevalence of Campylobacter spp. in poultry meat production chain and the risk for the development of the disease in humans. Th e Campylobacter jejuni/coli was identifi ed at farm level in 73.3% of poultry, 66.6% calves and 58.3% pig samples of already ill or suspected cases. Clinical manifestation of the disease in birds can be expected if an additional immunosuppressive factor is present. Artifi cial infection of healthy chickens with 6.77 log cfu C. jejuni per chicken on day 21st of life leads to 5.26 log cfu/g faeces aft er only fi ve days with a tendency to decrease during the next 18 days. Although chilling and freezing may signifi cantly reduce Campylobacter contamination of carcasses, it cannot completely eliminate the initial contamination. According to our experimental results the prevalence of Campylobacter contaminated chickens from positive fl ock appears to drop from 100% live birds (with 3.02 log cfu/g faeces) to 50% of chicken carcasses. Contamination of the carcasses depends on initial contamination of live birds, good hygiene practices andgood manufacturing practices. Th erefore, high variability in contamination of carcasses can be considered; prevalence range from 11.43 to 90.00% ofcarcases was established in various slaughterhouses. At retail, Campylobacter was detected in 18.8% poultry meat samples and 10.0% samples of othermeat types. Campylobacter is frequently found in the entire production chain of poultry meat and represents high risk for consumers’ health.

Abstract
Th is paper presents the results of chemical composition and microbiological safety testing of dry cured meat products, fermented and semi-dry or pasteurized sausages produced by several meat industries from Herzegovina. In the period from 2016 to 2018, a total of 85 meat products were sampled.Th ese included 20 samples of fermented pork sausages, 10 samples of dry-cured pork loin, 5 samples of dry-cured pork neck and 50 samples of heat-treated sausages. Quality control testing of the samples included determination of meat protein, crude fat, moisture, sodium nitrite and polyphosphates content in sausages, using standard analytical methods. It was confi rmed that all analysed samples meet the requirements in terms of chemical composition, level of additives and microbiological safety. In comparison with dry cured meat products and sausages analyses results, with minimum requirements that are set forth in regulations for that product category. Th e above mentioned suggests that the analysed samples are good quality products and they are in compliance with the regulations.

Abstract
Abstract
A valuable tool for external quality control that provides opportunity to improve analytical skills and techniques in the field of radioactivity measurements is participation in proficiency tests (PTs). In this work obtained results from the gamma spectrometry intercomparison for 15 laboratories conducted in May 1986 immediately after the Chernobyl accident for the lucerne sample contaminated with fission products: 140Ba, 141Ce, 144Ce, 134Cs, 137Cs, 131I, 103Ru, 106Ru, 95Zr, are evaluated following the recommendations of the international standard ISO 13528:2005. Environmental radioactivity proficiency tests organized by International Atomic Energy Agency (IAEA) are designed to identify analytical problems, to help members states to maintain their accreditation and to provide knowledge and technology transfer in this area. The Analytical Laboratories for the Measurement of Environmental Radioactivity (ALMERA) is a world-wide network of analytical laboratories capable to analyzed radioactivity contents, coordinated by IAEA. Institute for the Application of Nuclear Energy (INEP), University of Belgrade, is an official member since 2013. Annual PTs are organized by ALMERA for the network laboratories using sets of different samples. Based on the PT proposition each result should pass accuracy and precision test to be awarded the status ‘Accepted’, otherwise it lies on the status ‘Warning’ or ‘Not Accepted’. INEP was participated in three worldwide open (in 2006, 2007 and 2011) and six (in a period 2012–2016) PTs organized by IAEA and ALMERA. Radionuclide activity concentrations in different environmental matrices were measured using gamma-ray spectrometer with high purity germanium (HPGe) detector. In IAEA worldwide open PTs among 61 results, 74 % were ‘Accepted’ and 26 % were ‘Not Accepted’. In ALMERA network PTs among 70 results, 84.3 % were ‘Accepted’, 4.3 % were ‘Warning’, 11.4 % were ‘Not Accepted’. PT exercises are the best way to identify gaps and problems areas where further development is needed.

Abstract
A new regulation on Salmonella control in Serbia has been implemented recently. The main goal is to eliminate two most common serovars, Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST) from the poultry farms and to keep the infections caused by these bacteria under control. Experimental work conducted in the past decade in our Institute provided evidence that Salmonella is transmitted easily in a flock and is hard to be eliminated from the farms and hatcheries. This is in good agreement with the published research work by other authors. It is also evident that good management practice and vaccination strategy must be implemented in poultry production. Therefore a simple questionnaire for poultry producers and hatchery experts to provide a quick overview of the management practice was designed in order to find out shortcomings. Salmonella monitoring must be conducted by applying bacteriological examination while serology control is efficient more during exploitation and less during rearing. However, it was found out that bacteriology and serology can be successfully combined in order to estimate the infection status. Although regular bacteriological screening for salmonella is compulsory, some farmers in the country do not pursue this type of analysis at the recommended frequency. Subsequently, those who send the samples for bacteriological examination more often seem to have more salmonella related problems. The most frequent finding of salmonella was in the chickens that died during transportation and the first three days of life and from paper pads. Extremely rare finding of salmonella was in breeding eggs and even rarer in table eggs. If environmental samples from commercial layers are positive, serology testing is recommended. Salmonella isolated from chickens and farm premises in Serbia were susceptible to most antimicrobials tested. Multiple resistances was quite seldom but approximately 20% of the isolates were quinolone resistant. The resistance to fluoroquinolones was not detected. However, Salmonella highly resistant to nalidixic acid with MIC (minimal inhibitory concentration) to NAL > 512 mg/ml were less susceptible to ciprofloxacin, although MICs to CIP were still below the CLSI recommended breakpoint (R > 4 mg/ml). Similar reports were obtained in investigation of salmonella isolated from human stool and the research indicates that the most frequent serovar in the country in humans, food and poultry include Salmonella Enteritidis, Salmonella Typhimurium and Salmonella Infantis.

Abstract
CYP2C19 and CYP2D6 are important drug-metabolizing enzymes that are involved in the metabolism of around 30% of all medications. Importantly, the corresponding genes are highly polymorphic and these genetic differences contribute to interindividual and interethnic differences in drug pharmacokinetics, response, and toxicity. In this study we systematically analyzed the frequency distribution of clinically relevant CYP2C19 and CYP2D6 alleles across Europe based on data from 82,791 healthy individuals extracted from 79 original publications and, for the first time, provide allele confidence intervals for the general population. We found that frequencies of CYP2D6 gene duplications showed a clear South-East to North-West gradient ranging from <1% in Sweden and Denmark to 6% in Greece and Turkey. In contrast, an inverse distribution was observed for the loss-of-function alleles CYP2D6*4 and CYP2D6*5. Similarly, frequencies of the inactive CYP2C19*2 allele were graded from North-West to South-East Europe. In important contrast to previous work we found that the increased activity allele CYP2C19*17 was most prevalent in Central Europe (25–33%) with lower prevalence in Mediterranean-South Europeans (11–24%). In summary, we provide a detailed European map of common CYP2C19 and CYP2D6 variants and find that frequencies of the most clinically relevant alleles are geographically graded reflective of Europe’s migratory history. These findings emphasize the importance of generating pharmacogenomic data sets with high spatial resolution to improve precision public health across Europe.

Abstract
Circulating immune cells, which are recruited to the site of injury/disease, secrete various inflammatory mediators that are critical to nociception and pain. The role of tissue-resident immune cells, however, remains poorly characterized. One of the first cells to be activated in peripheral tissues following injury are γδT cells, which serve important roles in infection, disease, and wound healing. Using a mouse line lacking these cells, we sought to identify their contribution to inflammatory pain. Three distinct models of peripheral inflammatory pain were used: intraplantar injection of formalin (spontaneous inflammatory pain), incisional wound (acute inflammatory pain), and intraplantar injection of complete Freund's adjuvant (chronic inflammatory pain). Our results show that absence of γδT cells does not alter baseline sensitivity, nor does it result in changes to mechanical or thermal hypersensitivity after tissue injury. Myeloid cell recruitment did show differential changes between models of acute and chronic inflammatory pain. These results were consistent in both male and female mice, suggesting that there are no sex differences in these outcomes. This comprehensive characterization suggests that γδT cells do not contribute to basal sensitivity or the development and maintenance of inflammatory pain.

Abstract
Trichinellosis is one of the most important foodborne diseases in the Eastern European countries. The main objective of this study was to investigate the epidemiological patterns of trichinellosis outbreaks that occurred between 2005 and 2016 in Vojvodina, a northern province of the Republic of Serbia. The average incidence was 3.5 per 100,000 inhabitants. A total of 828 people acquired the infection. The disease occurred in all age groups, slightly more often in males, and quite frequently in a severe form considering the high share of hospitalised patients and the fatal outcome rate (41.6 ± 31.1% and 0.4%, respectively). Trichinella spiralis was confirmed as the causative agent in eight outbreaks. The outbreaks usually occurred among family members due to the consumption of pork or traditional pork products from not tested backyard pigs. Veterinary control measures and the education of consumers and farmers should be implemented to control this zoonotic disease.

Abstract
This is the first study offering insights into the prevalence of giant liver fluke in the population of red deer in the territory of Serbia. Giang liver fluke (Fascioloides magna, Bassi, 1875) is the most important liver parasite among wild ruminants in Europe, especially in the region of floodplain forests along the upper watercourse of Danube river. The main objective of this research was establishing the prevalence of giant liver fluke in the region of floodplain forests of northern Serbia. In the observed regions (hunting grounds), the population prevalence rates ranged from 0 to 80% with an average prevalence in positive herds being 70.6%. The total population of red deer, from the observed hunting grounds, exposed to the giant liver fluke includes 47.9% of red deer population in Serbia, which is 0.7% of the total hunting area of Serbia. Giant liver fluke is present in north-western regions of Serbia in a narrow area of floodplain forests along the watercourse of Danube and Sava rivers next to the border with Croatia. The red deers populating the wetland basin of “Gornje Podunavlje” migrate freely through the tri-border area of Hungary, Croatia and Serbia making a consistent epizootical unit. Moreover, the game migrates freely between Croatia and Serbia in the area of Posavina forests along the river Sava. All data obtained in this research are essential for further activities aimed at preventing the spread of this parasite within red deer population and thus decreasing consequent damages and losses.

Abstract
Magnesium (Mg), is not only a modulator of the glutamatergic NMDA receptors' affinity, it also prevents HPA axis hyperactivity, thus possibly being implicated in neurobiological features of mood disorders. Further uncovering of molecular mechanisms underlying magnesium's proposed effects is needed due to the recent shift in research of treatment resistant depression (TRD) towards glutamatergic pathways. Here, we applied Mg via drinking water for 28 days (50 mg/kg/day), in ACTH-treated rats, an established animal model of depression resistant to tricyclic antidepressants. Using this model in male rats we measured (1) changes in hippocampal neurogenesis and behavioral alterations, (2) adrenal hormones response to acute stress challenge and (3) levels of biometals involved in regulation of monoamines turnover in rat prefrontal cortex. Our results support beneficial behavioral impact of Mg in TRD model together with increased hippocampal neurogenesis and BDNF expression. Furthermore, Mg prevented ACTH-induced disruption in HPA axis function, by normalizing the levels of plasma ACTH, corticosterone and interleukin-6, and by increasing the peripheral release of adrenaline, noradrenaline and serotonin after the acute stress challenge. Finally, the influence on copper/zinc ratio suggested probable magnesium's involvement in monoamine turnover in PFC. Our findings provide further insights into the possible pathways implicated in the behavioral modulation effects of Mg, as well as its central and peripheral effects in ACTH-induced TRD model. Thus, further investigation of molecular signaling related to the glutamatergic transmission and role of Mg, could reveal prospects to novel treatment strategies that could be of particular importance for patients suffering from TRD.

Abstract
We address the stability and dynamics of eigenmodes in linearly shaped strings (dimers, trimers, tetramers, and pentamers) built of droplets in a binary Bose-Einstein condensate (BEC). The binary BEC is composed of atoms in two pseudo-spin states with attractive interactions, dressed by properly arranged laser fields, which induce the (pseudo-) spin-orbit (SO) coupling. We demonstrate that the SO-coupling terms help to create eigenmodes of particular types in the strings. Dimer, trimer, and pentamer eigenmodes of the linear system, which correspond to the zero eigenvalue (EV, alias chemical potential) extend into the nonlinear ones, keeping an exact analytical form, while tetramers do not admit such a continuation, because the respective spectrum does not contain a zero EV. Stability areas of these modes shrink with the increasing nonlinearity. Besides these modes, other types of nonlinear states, which are produced by the continuation of their linear counterparts corresponding to some nonzero EVs, are found in a numerical form (including ones for the tetramer system). They are stable in nearly entire existence regions in trimer and pentamer systems, but only in a very small area for the tetramers. Similar results are also obtained, but not displayed in detail, for hexa- and septamers.

Abstract
During 2015/2016, fecal and intestinal samples from live diseased and/or dead pigs with suspected PEDV and/or TGEV and signs of rotavirus infection were collected from in total seven different farrow-to-finish swine farms located in Northern Serbia region (Vojvodina Province). A total of 14 samples (2 pools per farm) of small intestine with fecal content were submitted to laboratory molecular investigation (multiplex RTPCR). On these farms the clinical signs included the occurrence of diarrhea in suckling and weaned piglets, with weak or no response to the applied antimicrobial therapy. The epidemic of severe diarrhea affecting pigs of all ages on one farrow-to finish swine farm was detected in January 2016. Watery diarrhea in all swine categories was associated with vomiting and a reduction in feed consumption. Diarrheic, gaunt and dehydrated piglets, covered with feces were found in 90% litters. The disease affected most severely the suckling piglets, and the mortality in newborn piglets was up to 35%. In the weaned piglets and fatteners the mortality was up to 2.5% and 1.2%, respectively. The PEDV RNA was detected in pooled feces and samples of small intestines derived from diseased and dead suckling piglets from only one investigated farm. The PEDV positive samples showed to be negative for rotavirus group A and TGEV. The transport vehicles were identified as the main possible route of PEDV introduction. This is the first report demonstrating the presence of PEDV in Serbia.

Abstract
Methicillin-resistant Staphylococcus aureus is one of the most important human pathogens. Th ese bacteria have the ability to colonize animals andcross species barriers. Th ree major groups of MRSA strains have emerged. Healthcare associated MRSA and community acquired MRSA strains have potential to spread worldwide and oft en persist in hospitals and communities as clonal strains. Th e livestock-associated MRSA has been isolated from healthy human carriers but also from infected patients all around the world. Molecular typing of staphylococcal cassette chromosome mec (SCCmec), multilocus sequence typing in combination with pulse fi eld gel electrophoresis and spa typing are most frequently used for genetic characterization of MRSA strains. Th e community-acquired MRSA strains are capable of producing Panton Valentine leukocidin (PVL) cytotoxin which is their major virulence determinant. MRSA strains possess a number of virulence factors that are common in other bacteria and it is still not entirely explained which virulence factors or mechanisms of their regulation are important for the pathogenic potential, persistence in the environment or the ability to cause detrimental infection in patients. Recently, as a contribution to the progress of molecular biology, peculiar mechanisms of genetic regulation of virulence genes have been discovered and their role in pathogenesis of infection and epidemiology of MRSA has been studied.

Abstract
BACKGROUND This paper is the short review of our preliminary results obtained with 99mTc-EDDA/HYNIC-TOC. MATERIAL AND METHODS The total of 495 patients with different neuroendocrine tumors were investigated during last few years. RESULTS There have been 334 true positive (TP), 73 true negative (TN), 6 false positive (FP) and 82 false negative findings (FN). Diagnosis was made according to SPECT findings in 122 patients (25%). The mean T/NT ratio for TP cases was significantly higher (p < 0.01) on SPECT (3.12 ± 1.13) than on whole body scan (2.2 ± 0.75). According to our results, overall sensitivity of the method is 80%, specificity 92%, positive predictive value 98%, negative predictive value 47% and accuracy 82%. Fifteen TP patients underwent therapy with 90Y-DOTATATE. CONCLUSION Scintigraphy of neuroendocrine tumors with 99mTc-Tektrotyd is a useful method for diagnosis, staging and follow up of the patients suspected to have neuroendocrine tumors. SPECT had important role in diagnosis. It is also helpful in the appropriate choice of the therapy, including the peptide receptor radionuclide therapy. In the absence of 68Ga-labeled peptides and PET/CT, the special emphasize should be given to application of SPECT/CT as well as to the radioguided surgery.

Abstract
The aim of this study was to determine the level of organochlorine (OC) pesticides in 57 samples of canned tuna and 31 samples of canned sardines in vegetable oil, collected from supermarkets in Serbia. OC pesticides α-HCH, β-HCH, δ-HCH, dichlorodiphenyltrichloroethane (DDT), DDE, DDD, dielderin, endosulfane I, endosulfane II, endosulan sulfate, endrin, endrin ketone, heptachlor, heptachlor epoxide, lindane, aldrin, metoxichlor, cis-chlordane and trans-chlordane were determined using a GS-MS method. The highest concentrations (µg kg-1, arithmetic means) in canned tuna were for δ-HCH (60.6 ± 97.0) and p, p´-DDT (55.0 ± 25.1), while the corresponding values in canned sardines were for δ-HCH (90.7 ± 102.7) and endosulfane II (78.0 ± 145.9). Mean level for the sum of endosulfans was above the maximum limit in canned sardines (85.0 µg kg-1). Also, dieldrin (39.7 µg kg-1) was measured above the ML.

Abstract
Summary
The aim of the paper was to determine the factors related to the initial therapy that may contribute to death from severe necrotizing acute pancreatitis and to analyze their clinical importance as well as possible additive effects.
A retrospective case-control study included all adult patients treated for severe necrotizing acute pancreatitis in the Clinical Center of Kragujevac, Serbia, during the five-year period (2006-2010.). The cases (n = 41) were patients who died, while the controls (n = 69) were participants who survived. In order to estimate the relationship between potential risk factors and observed outcome, crude and adjusted odds ratios (OR) with 95 % confidence intervals (CI) were calculated in logistic regression models.
Significant association with observed outcome was shown for the use of gelatin and/or hydroxyethyl starch (adjusted OR 12.555; 95 % CI 1.150-137.005), use of albumin (adjusted OR 27.973; 95 % CI 1.741-449.373), use of octreotide (adjusted OR 16.069; 95 % CI 1.072-240.821) and avoiding of enteral feeding (adjusted OR 3.933; 95 % CI 1.118-13.829), while the use of nonsteroidal anti-inflammatory drugs had protective role (adjusted OR 0.057; 95 % CI 0.004-0.805).
The risk of death in patients with predicted severe necrotizing acute pancreatitis could be reduced with avoidance of treatment with colloid solutions, albumin and octreotide, as well as with an early introduction of oral/enteral nutrition and use of nonsteroidal anti-inflammatory drugs.

Abstract
Contemporary lifestyle is commonly associated with chronic stress, an environmental factor contributing to development of various psychological and somatic disorders. Increased levels of glucocorticoids, observed in the chronic stress, induce the production of reactive oxygen species leading to genotoxicity. The aim of this study was to investigate whether chronic administration of oxytocin (OXY) 10 IU/400 μL/day, s.c., for 14 days, a hormone presumed to exert antioxidant effect, may prevent DNA damage in the comet assay of peripheral blood lymphocytes of Wistar rats treated chronically with corticosterone (CORT) 100 mg/L ad libitum, per os, for 21 days, as well as, to influence some plasma oxidative stress parameters, i.e. levels of total lipid hydroperoxide (LOOH), and malondialdehyde (MDA), and the activity of antioxidative enzyme superoxide dismutase (SOD). Even though there was no reduction in overall number of damaged cells after oxytocin treatment only, the marked increase in total comet score (TCS) after incubation with H2O2 in CORT group compared to controls, was absent in the CORT + OXY experimental group. Furthermore, significant decrease of highly damaged cells compared to corticosterone group was noted. Chronic oxytocin administration thus protected lymphocytes from high intensity damage that leads to cellular death. In addition, treatment with OXY along with CORT, significantly decreased concentration of LOOH in plasma, and increased SOD compared to CORT treatment only. This finding corresponds well with current reports on beneficial effects of OXY in conditions of HPA axis hyperactivity, and supports the hypothesis of OXY-mediated antioxidant action.

Abstract
The need for reliable assessments of soil erosion rates in Serbia has directed attention to the potential for using (137)Cs measurements to derive estimates of soil redistribution rates. Since, to date, this approach has not been applied in southeastern Serbia, a reconnaissance study was undertaken to confirm its viability. The need to take account of the occurrence of substantial Chernobyl fallout was seen as a potential problem. Samples for (137)Cs measurement were collected from a zone of uncultivated soils in the watersheds of Pčinja and South Morava Rivers, an area with known high soil erosion rates. Two theoretical conversion models, the profile distribution (PD) model and diffusion and migration (D&M) model were used to derive estimates of soil erosion and deposition rates from the (137)Cs measurements. The estimates of soil redistribution rates derived by using the PD and D&M models were found to differ substantially and this difference was ascribed to the assumptions of the simpler PD model that cause it to overestimate rates of soil loss. The results provided by the D&M model were judged to more reliable.

Abstract
This paper promotes the biometric classification system of plant cultivars, unique characteristics, in terms of the uranium (U) uptake, primarily in the function of the application for phytoremediation. It is known that the degree of adoption of U depends on the plant species and its morphological and physiological properties, but it is less known what impact have plants cultivars, sorts, and hybrids. Therefore, we investigated the U adoption in four cultivars of three plant species (corn, sunflower and soy bean). "Vegetation experiments were carried out in a plastic-house filled with soil (0.66 mgU) and with tailing (15.3 mgU kg(-1)) from closed uranium mine Gabrovnica-Kalna southeast of Serbia". Principal Component Analysis (PCA), Cluster Analysis (CA) and analysis of variance (ANOVA) were used for assessing the effect of different substrates cultivars, plant species and plant organs (root or shoot) on U uptake. Obtained results showed that a difference in U uptake by three investigated plant species depends not only of the type of substrate types and plant organs but also of their cultivars. Biometrics techniques provide a good opportunity for a better understanding the behavior of plants and obtaining much more useful information from the original data.
