AB  - The health effects attributed to exposure to ambient PM2.5 concentrationsabove 10 μg/m3by using the AirQ+ modeling software were assessed. Thehourly concentrations of PM2.5 were collected from 13 air pollutionmonitoring stations in the Belgrade district during Jun and July 2021.,which were further used as input data for the AirQ+software. The averageconcentration of PM2.5 for two-month monitoring from all sampling sites inthe city was 14.8 μg/m3, the maximum daily concentration was 55.7 μg/m3,while the maximum concentration per hour was 365 μg/m3. The spatialdistribution of concentrations was mapped using geostatistical interpolation,revealing hotspots within the city centre and industrial area of the district.The burden of disease, such as stroke, ischemic heart disease (IHD), chronicobstructive pulmonary disease (COPD) and lung cancer (LC), due to theambient PM2.5 pollution was evaluated according to the WHO methodologyfor health risk assessment of air pollution. The model used for thisassessment is based on the attributable proportion defined as the section ofthe health effect related to exposure to air pollution in an at-risk population.The estimated attributable proportion was 19.4% for stroke, 27.2% for IHD,15.3% for COPD and 9.0% for LC. The estimated number of attributablecases per 100,000 population at risk, due to PM2.5 air pollution, for stroke,IHD, COPD, and LC, was 28, 34, 15, and 8, respectively.

AB  - Fly ash originating from coal combustion in thermal power plants is generated in landfills in large amounts, and due to the high content of heavy metals and metalloids whose mobility is hazardous to the environment and human health, it causes soil and groundwater pollution. Scientific research in the field of "alternative mining" is significant, where heavy metals and rare earth elements would be recovered from waste materials such as fly ash using various extraction methods. The aim of this paper is to determine the optimal extraction process of the examined elements: V, Cr, Mn, Co, Ni, Cu, Zn, As, Cd, and Pb from fly ash. Two extraction agents were used: sulfuric and acetic acid. In the first set of experiments, the fly ash was immersed immediately in acids, and in the second set, this process was preceded by the addition of sodium hydroxide, which effectively destroys the alumina-silicate matrix. Several different parameters were also monitored: ratio of fly ash and acid/acid mixture (1:5, 1:30), temperature (25 and 45°C), duration of the process (4 and 24 h), and stirring. For the extraction of Pb - H2SO4, temperature and time were shown as significant parameters, while for Cd, only H2SO4 was an effective extractant. Concerning the As metalloid, the acetic acid, solid/liquid ratio, and time were significant, while for Zn, Cu, Co, Mn, and V metals only the solid/liquid ratio was significant. Determination of the content of heavy metals and metalloids was done by the ICP-MS.

AB  - Sagorevanjem uglja u termoelektranama nastaju velike količine letećeg pepela koji u svom sastavu sadrži teške metale i metaloide čije izluživanje može naruštiti stanje životne sredine u ve- likoj meri. Cilj ovog rada jeste optimizacija procesa stabilizacije matrice letećeg pepela upotrebom oksida, hidroksida i karbonata kalcijuma, kao i ispitivanje stepena desorpcije (izluživanje) ele- menata u desorpcionim rastvorima. Stabilizacijom letećeg pepela omogućila bi se njegova dalja upotrebe u građevinskoj industriji ili u svrhu adsorbenta. Kako bi se dobili optimalni uslovi korišćeno je nekoliko različitih stabilizatora (CaO, Ca(OH)2 i CaCO3) u različitim koncentracijama (5% i 7%). Variraran je i sastav desorpcionog rastvora (dejonizovana voda i 4% i 8% sirćetna kiselina) kao i odnos letećeg pepela i desoprcionog rastvora (1:10 i 1:30). Koncentracija jona teških metala i metaloida (V, Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Pb) određivana je metodom masene spektrometrije sa indukovano spregnutom plazmom (ICP- MS).

AB  - Combustion of coal in thermal power plants produces large amounts of fly ash, which contains heavy metals and metalloids, and their leaching can greatly damage the environment. The aim of this paper is to optimize the process of stabilization of the fly ash matrix using calcium oxide, hydroxide and carbonate, as well as to examine the degree of desorption (leaching) of elements in desorption solutions. Stabilization of fly ash would enable its further use in the construction industry or as an adsorbent. In order to obtain optimal conditions, several different stabilizers (CaO, Ca(OH)2 and CaCO3) were used in different concentrations (5% and 7%). The composition of the desorption solution (deionized water and 4% and 8% acetic acid) is also variable, as is the ratio of fly ash to the desorption solution (1:10 and 1:30). The concentration of heavy metal ions and metalloids (V, Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Pb) was determined by the method of Inductively coupled plasma mass spectrometry (ICP-MS). Multivariate statistical analysis (correlation analysis, principal component analysis (PCA) and cluster analysis (CA)) was performed for data processing. MINITAB statistical software was used.

AB  - Management of waste polymers (polyethylene - PE and polypropylene - PP) represents one of the major obstacles in the field of environmental protection, which demands a most efficient and eco-friendly technological solution. Due to the high use of various plastic materials, the amount of landfilled or dissipated plastic waste is continuously growing. Therefore, this paper examines the possibilities of recycling these polymers, alongside obtaining granules of similar or advanced physico-mechanical characteristics to the commercially available ones. The applied technology consists of several consecutive processes (collecting, grinding, washing and extruding) where the obtained materials can later be incorporated into widely applicable products, such as foils, bin liners, bags, among others. In this way, high-quality products with great market potential are obtained, which will consequently contribute to lower extraction and less depletion of natural resources. Thus major problems may be solved optimally, consolidating the efficiency of improved eco-friendly technologies which is in line with environmental protection and sustainable waste management.

AB  - The Republic of Serbia predominantly produces electricity in thermal power plants (TPP) Nikola Tesla (A i B), Kolubara and Kostolac. They are supplied from Kolubara basin mines (Nikola Tesla (A i B), Kolubara) which produces three quarters of Serbian lignite (about 70%), with the mean annual production about 30 million tons of coal and from Kostolac basin (TE Kostolac) which produces 30% of lignite in Serbia. Coal combustion residuals include bottom ash, fly ash and slag. Environmental pollution by coal ash and fly ash has been intensively studied taking into account high content of potentially hazardous elements such as As, Pb, Cd and Cr. Tracking lead sources in environmental studies has usually been performed by stable lead isotopes. The pres- ence, pathways and environmental impact of coal ash and fly ash can be identified using Pb isotopic compositions. In this study, isotopic compositions for 12 coal samples from Kolubara and Kostolac major coal mines and 12 fly ash samples from thermal power plants Kolubara (A and B), Kostolac (A and B), Nikola Tesla TENT (A3, A2, and B1) were determined. Samples were digested in mineral acids mixture. Lead conc- entration and stable Pb isotopes were measured by inductively coupled plasma mass spectrometry (ICP-MS). The results obtained might be useful in monitoring of Pb poll- ution from the examined sources, as well as in emission control.

Coal is extracted from the Kolubara basin, which produces approximately 70% of lignite (an average of 30 million tons per year), and the Kostolac basin, which produces 30% of lignite. Ash, fly ash, and slag are examples of coal combustion residues. Because of the high content of potentially hazardous elements such as As, Pb, Cd, and Cr, environmental pollution with ash and fly ash has been extensively researched. Stable isotopes of lead can be used to trace lead sources. It is possible to monitor the presence, transformation pathways, and environmental impact of Pb by determining its isotopic composition in coal and fly ash. For the first time, the isotopic composition of selected coal samples from the Kolubara and Kostolac mines, as well as fly ash from the Kolubara (A and B), Kostolac (A and B), and Nikola Tesla (TENT A3, A2, B2) thermal power plants, was investigated in this study. The obtained data for 206Pb/207Pb in coal serve as the foundation for ranking domestic coals, whereas the isotopic ratios 206Pb/207Pb and 208Pb/207Pb  in fly ash can be used to monitor and control lead pollution from investigated sources.

AB  - This study investigated the use of different natural raw soil materials as low-cost adsorbents for the removal to remove As(V) and Pb(II) from aqueous systems. It deals with the effect of different soil textures, sandy loam, loam, and loamy sand, on adsorption efficiency. Fourier-transform infrared spectroscopy (FTIR) was used to carry out the comprehensive characterization of materials, as well as scanning electron microscopy (SEM), X-ray diffraction (XRD), and liquid nitrogen porosimetry or the Brunauer–Emmett–Teller (BET). Studies were performed in a batch system; the initial concentration of examined heavy metals was 100 μg·L–1, pH varied in the range of 4–6, and the adsorbent dosage was 5–20 mg/10 mL. Sandy loam was the most efficient adsor-bent for As(V) separation, with a maximum removal efficiency of 47.5%, while the loam was the most efficient for Pb(II) separation, with a maximum removal efficiency of 94.2%. The removal efficiency was affected mainly by the adsorbent characteristics. Performed kinetic studies revealed two steps of adsorption for both investigated ions. Obtained results indicate that natural sorbents used in this work present environmentally sustainable material for As(V) and Pb(II) removal, on the one hand, and the basis for further studies on the simultaneous removal of heavy metals from water and their reduced mobility in soil, on the other. © 2022 Desalination Publications.

AB  - Fly and bottom ash(es) are the most abundant generated by-products of coal combustion in thermal power plants. This investigation offers a sustainable solution of a double and circular use of industrial waste material in civil engineering practices; i.e., fly ash (FA) as an eco-efficiently, low-cost material for As(V) adsorption, as well as an additive in building materials. A goethite impregnated sample (FAG) was synthesized and optimized using the column precipitation procedure, then thoroughly, structurally and morphologically characterized using liquid nitrogen porosimetry (BET), X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and Mössbauer spectroscopy (MS) techniques. The data from the equilibrium adsorption were fitted by linear and non-linear isotherm models; the optimal capacity of FAG/As(V) removal was calculated from the Langmuir model at 31.742 mg g−1 for 45 °C. The kinetics of adsorption process has shown the pseudo-second-order kinetic model (PSO). The Weber-Morris model was applied to determine the intra-particle diffusion as a limiting step of reaction. The low pH dependant FAG leaching confirmed the efficient use of non-hazardous waste material in arsenic removal; furthermore, it also validated the new added value of the used/spent adsorbent as an adhesive in building materials possessing advanced mechanical properties. © 2021 Elsevier Ltd

AB  - Olovo i arsen predstavljaju značajnu grupu neorganskih polutanata koji su prisutni uživotnoj sredini, pre svega u vodenim sistemima, pa je njihovo uklanjanje veliki tehničkotehnološki izazov. Zbog toga se sve više pažnje posvećuje razvoju pristupačnih, efikasnih iekološki prihvatljivih adsorbenata. Prirodni materijali na bazi oksida metala (SiO2, Al2O3,Fe2O3), poput ilovače, predstavljaju efikasne adsorbente za uklanjanje katjonskih i anjonskihvrsta iz vodenih rastvora. U ovom radu adsorpciona svojstva ilovače ispitivana su u šaržnomsistemu, promenom pH vrednosti početnog rastvora, dok su masa adsorbenta, vreme itemperature procesa bili konstantni. Značajnu ulogu u odvijanju adsorpcionog procesa ima pHvrednost rastvora, stoga se eksperiment zasnivao na određivanju efikasnosti procesa pri vrednostipH rastvora 4, 5 i 6. Strukturne karakteristike ilovače su određene primenom rendgenskedifrakcione analize (engl. X-Ray Difraction, XRD), infracrvenom spektroskopijom sa Furijeovomtransformacijom (engl. Fourier-Transform Infrared Spectroscopy, FTIR) i skenirajuće elektronskemikroskopije (engl. Scanning electron microscopy, SEM). Koncentracija jona nakon procesaadsorpcije određena je pomoću indukovano spregnute plazme sa masenom spektrometrijom (engl.Inductively Coupled Plasma Mass Spectrometry, ICP-MS). Maksimalna efikasnost uklanjanjajona olova postignuta je na pH vrednosti 5 (94,2 %), dok je za jone arsena optimalna pH vrednostbila 6 (35,1 %).
AB  - Lead and arsenic represent an important group of inorganic pollutants that can be found in the environment, primarily in aquatic systems. Their removal from water systems is a big environmental problem, but also a significant technological challenge. Therefore, an increasing attention is paid to the development of widely available, efficient and environmentally friendly adsorbents. Natural metal oxide-based materials (SiO2, Al2O3, Fe2O3), such as loam, are effective adsorbents for removal of cationic and anionic species. The adsorption experiments were performed in a batch system, varying the pH value of the initial solution, while the mass of adsorbent, time and temperature were constant. The influence of pH value has a leading influence to the adsorption process so the process efficiency was determined at the pH values set at: 4, 5 and 6. The structural characteristics of the loam was performed using X-ray diffraction analysis (XRD), Fourier-Transform Infrared Spectroscopy (FTIR) and scanning electron microscopy (SEM). The concentration of ions after their removal was determined using inductively coupled plasma mass spectrometry (ICP-MS). The maximum removal of lead ions was obtained at pH 5 (94.2%), while for arsenic ions, it was at pH 6 (35.1%).

abstract = "Olovo i arsen predstavljaju značajnu grupu neorganskih polutanata koji su prisutni uživotnoj sredini, pre svega u vodenim sistemima, pa je njihovo uklanjanje veliki tehničkotehnološki izazov. Zbog toga se sve više pažnje posvećuje razvoju pristupačnih, efikasnih iekološki prihvatljivih adsorbenata. Prirodni materijali na bazi oksida metala (SiO2, Al2O3,Fe2O3), poput ilovače, predstavljaju efikasne adsorbente za uklanjanje katjonskih i anjonskihvrsta iz vodenih rastvora. U ovom radu adsorpciona svojstva ilovače ispitivana su u šaržnomsistemu, promenom pH vrednosti početnog rastvora, dok su masa adsorbenta, vreme itemperature procesa bili konstantni. Značajnu ulogu u odvijanju adsorpcionog procesa ima pHvrednost rastvora, stoga se eksperiment zasnivao na određivanju efikasnosti procesa pri vrednostipH rastvora 4, 5 i 6. Strukturne karakteristike ilovače su određene primenom rendgenskedifrakcione analize (engl. X-Ray Difraction, XRD), infracrvenom spektroskopijom sa Furijeovomtransformacijom (engl. Fourier-Transform Infrared Spectroscopy, FTIR) i skenirajuće elektronskemikroskopije (engl. Scanning electron microscopy, SEM). Koncentracija jona nakon procesaadsorpcije određena je pomoću indukovano spregnute plazme sa masenom spektrometrijom (engl.Inductively Coupled Plasma Mass Spectrometry, ICP-MS). Maksimalna efikasnost uklanjanjajona olova postignuta je na pH vrednosti 5 (94,2 %), dok je za jone arsena optimalna pH vrednostbila 6 (35,1 %)., Lead and arsenic represent an important group of inorganic pollutants that can be found in the environment, primarily in aquatic systems. Their removal from water systems is a big environmental problem, but also a significant technological challenge. Therefore, an increasing attention is paid to the development of widely available, efficient and environmentally friendly adsorbents. Natural metal oxide-based materials (SiO2, Al2O3, Fe2O3), such as loam, are effective adsorbents for removal of cationic and anionic species. The adsorption experiments were performed in a batch system, varying the pH value of the initial solution, while the mass of adsorbent, time and temperature were constant. The influence of pH value has a leading influence to the adsorption process so the process efficiency was determined at the pH values set at: 4, 5 and 6. The structural characteristics of the loam was performed using X-ray diffraction analysis (XRD), Fourier-Transform Infrared Spectroscopy (FTIR) and scanning electron microscopy (SEM). The concentration of ions after their removal was determined using inductively coupled plasma mass spectrometry (ICP-MS). The maximum removal of lead ions was obtained at pH 5 (94.2%), while for arsenic ions, it was at pH 6 (35.1%).",

AB  - Urban wastewater treatment plants (WWTPs) are among the main anthropogenic sources for the release of contaminants of emerging concern (CECs) into the environment, which can result in toxic and adverse effects on aquatic organisms and consequently on humans. Unfortunately, WWTPs are not designed to remove CECs and secondary (e.g., conventional activated sludge process, CAS) and tertiary (such as filtration and disinfection) treatments are not effective in the removal of most CECs entering WWTP. Accordingly, several advanced treatment methods have been investigated for the removal of CECs from wastewater, including consolidated (namely, activated carbon (AC) adsorption, ozonation and membranes) and new (such as advanced oxidation processes (AOPs)) processes/technologies. This review paper gathers the efforts of a group of international experts, members of the NEREUS COST Action ES1403 who for three years have been constructively discussing the state of the art and the best available technologies for the advanced treatment of urban wastewater. In particular, this work critically reviews the papers available in scientific literature on consolidated (ozonation, AC and membranes) and new advanced treatment methods (mainly AOPs) to analyse: (i) their efficiency in the removal of CECs from wastewater, (ii) advantages and drawbacks, (iii) possible obstacles to the application of AOPs, (iv) technological limitations and mid to long-term perspectives for the application of heterogeneous processes, and (v) a technical and economic comparison among the different processes/technologies. © 2018 Elsevier B.V.

AB  - This work examines the mill scale (MS) of hot rolling, a waste product formed in industrial steel processing. MS was evaluated as an iron source in promoting the oxidation of Reactive Red 120 azo dye in location-sourced and factory textile wastewater through a Fenton reaction (FR), as well as reducing hexavalent chromium species to its trivalent form in the presence of an organic ligand (citric acid). The MS was characterised by various techniques and the results showed that iron is the major compound in its composition and occurs mainly in the form of oxides (wüstite, hematite and magnetite). In addition, it has ferromagnetic properties, which facilitate its separation. In the oxidation tests it was observed that acidic pH conditions promoted a positive influence on the reaction efficiency and that the presence of H2O2 can limit the leaching of iron into the solution. The best experimental conditions for colour removal from a RR 120 dye solution containing 35 mg L−1 were 15 g L−1 of MS, 0.5 mM H2O2, pH 3, 25 °C, 200 ± 2 rpm and 120 min. Furthermore, the homogeneous Fenton reaction showed a significant contribution to decolourisation, but the heterogeneous phase cannot be neglected since it is predominant at the beginning of the reactions. In the continuous process, the influence of the H2O2 concentration and the feed rate was evaluated, obtaining an optimal dose of 0.5 mM H2O2 for the RR dye 120 and 0.7 mM H2O2 for the real textile effluent, with a flow rate of 0.25 mL min−1 and pH 3 for both. Subsequently, the residue was evaluated as the source of iron in the process of reducing Cr(VI) to Cr(III). An increase in the efficiency of the reaction in the presence of citric acid was observed, associated with the removal of the surface oxide layer through the formation of soluble Fe(III)–Cr(III)-ligand complexes and the consequent increase of the iron redox cycle, reducing it to sequencing the reduction of chromium. 100% reduction was obtained in 30 min of reaction using 20 g L−1 of MS, at pH 3 and Cr(VI):citric acid ratio of 1:4. In continuous operation mode, 100% Cr(VI) reduction was obtained during 50 h (1.0 mL min−1 flow rate), dropping to 20% with increasing flow rate to 4.0 mL min−1 after 200 h of assay. © 2018 Elsevier Ltd

AB  - Fly ash (FA) is a by-product created from the burning of coal in thermal power plants. FA mainly consists of mineral compounds that make them naturally caustic. Despite this, research has shown that FA may be utilized as an alternative material in civil engineering, hydrotechnics and agronomy. Leaching tests may provide theoretical validation that FA may be used as an alternative sorbent or additive in construction material. In this paper, the results of up-flow percolation tests performed on raw FA as well as lime and cement modified samples (MFA) are presented. This method was chosen as it yields the most reliable assessment of releasing heavy metals under long-term exploitation. The research has focused on the leaching behaviour of Sb, As and Se in raw, lime and cement MFA samples. Raw FA was found to leach Se, As and Sb metal ions, cement modification did not prevent Sb and Se leachates, while lime-modified MFA was found to be the most stable material.

AB  - The modification of the fly ash (FA) by magnetite (M) was performed to obtain FAM adsorbent with improved adsorption efficiency for arsenate removal from water. The novel low cost adsorbents are characterized by liquid nitrogen porosimetry (BET), scanning electron microscopy (SEM), X-ray diffraction (XRD), Mössbauer spectroscopy (MB) and Fourier transform infrared (FTIR) spectroscopy. The optimal conditions and key factors influencing the adsorbent synthesis are assessed using the response surface method (RSM). The adsorption experiment was carried out in a batch system by varying the contact time, temperature, pH, and mass of the adsorbent. The adsorption capacity of the FAM adsorbent for As(V), calculated by Langmuir model, was 19.14 mg g−1. The thermodynamic parameters showed spontaneity of adsorption with low endothermic character. The kinetic data followed the pseudo-second-order kinetic model (PSO), and Weber-Morris model indicated intra-particle diffusion as rate limiting step. Alternative to low desorption capability of the FAM was found by five consecutive adsorption/magnetite precipitation processes which gave exhausted layered adsorbent with 65.78 mg g−1 capacity. This research also has shed light on the mechanism of As(V)-ion adsorption, presenting a promising solution for the valorization of a widely abundant industrial waste. © 2018 Elsevier Ltd

AB  - This study focuses on the use of raw fly ash (FA) and modified fly ash – activated by lime (MFA), as effective and low-cost adsorbents for the removal of heavy metals (Zn2+, Pb2+and As(V)), followed by the revalorization of the exhausted adsorbent. The granulometric, elemental analysis, point of zero charge (pHPZC), radiochemical and structural characterization were conducted using X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) and gamma spectrometry techniques. The optimal conditions and key factors influencing the adsorption process were assessed using the response surface method (RSM). The adsorption capacity of the MFA adsorbent for Zn2+, Pb2+and As(V) removal, calculated by the Langmuir model, was found to be 33.13, 26.06, and 29.71 mg g−1, respectively. The kinetic and thermodynamic parameters indicated that the adsorption process is spontaneous and endothermic. Due to their low desorption potential of the exhausted adsorbents, their effective reuse was established to be feasible. For this reason, the valorization of this material as an additive in construction materials was thereafter studied, where testing its toxicity leaching (TCLP) as well as the mechanical properties of construction material containing exhausted MFA confirmed its safe use.

abstract = "This study focuses on the use of raw fly ash (FA) and modified fly ash – activated by lime (MFA), as effective and low-cost adsorbents for the removal of heavy metals (Zn2+, Pb2+and As(V)), followed by the revalorization of the exhausted adsorbent. The granulometric, elemental analysis, point of zero charge (pHPZC), radiochemical and structural characterization were conducted using X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) and gamma spectrometry techniques. The optimal conditions and key factors influencing the adsorption process were assessed using the response surface method (RSM). The adsorption capacity of the MFA adsorbent for Zn2+, Pb2+and As(V) removal, calculated by the Langmuir model, was found to be 33.13, 26.06, and 29.71 mg g−1, respectively. The kinetic and thermodynamic parameters indicated that the adsorption process is spontaneous and endothermic. Due to their low desorption potential of the exhausted adsorbents, their effective reuse was established to be feasible. For this reason, the valorization of this material as an additive in construction materials was thereafter studied, where testing its toxicity leaching (TCLP) as well as the mechanical properties of construction material containing exhausted MFA confirmed its safe use. Hence, this study points to a possible “two-in-one” reuse of coal ash, initially as an adsorbent and later as an additive in a construction material.",

AB  - The objective of this study was to investigate the modification of materials used in wastewater treatment for possible antimicrobial application(s). Granulated activated carbon (GAC) and natural clinoptilolite (CLI) were activated using Cu2+-and Zn2+-ions and the disinfection ability of the resulting materials was tested. Studies of the sorption and desorption kinetics were performed in order to determine and clarify the antimicrobial activity of the metal-activated sorbents. The exact sorption capacities of the selected sorbents, GAC and CLI, activated through use of Cu2+-ions, were 15.90 and 3.60 mg/g, respectively, while for the materials activated by Zn2+-ions, the corresponding capacities were 14.00 and 4.72 mg/g,. The desorption rates were 2 and 3 orders of magnitude lower than their sorption efficacy for the Cu2+-, and Zn2+-activated sorbents, respectively. The intermediate sorption capacity and low desorption rate indicated that the overall antimicrobial activity of the metal-modified sorbents was a result of metal ions immobilized onto surface sites. The effect of antimicrobial activity of free ions desorbed from the metal-activated surface may thus be disregarded. The antimicrobial activities of Cu/GAC, Zn/GAC, Cu/CLI and Zn/ CLI were also tested against Escherichia coli, Staphylococcus aureus, and Candida albicans. After 15 min exposure, the highest levels of cell inactivation were obtained through the Cu/CLI and the Cu/GAC against E. coli, 100.0 and 98.24%, respectively. However, for S. aureus and yeast cell inactivation, all Cu2+-and Zn2+-activated sorbents proved to be unsatisfactory. A characterization of the sorbents was performed by Xray diffraction (XRD), X-ray photo electron spectroscopy (XPS), and field emission scanning electron microscopy (FE-SEM). A concentration of the adsorbed and released ions was determined by inductively coupled plasma-optical emission spectroscopy (ICP-OES) and mass spectrometry (ICP-MS). The results showed that the antimicrobial performance of the activated sorbents depended on the surface characteristics of the material, which itself designates the distribution and the bioavailability of the activating agent.

AB  - The activity concentrations of natural radionuclides (K-40, Pb-210, Po-210, Ra-226 and Ra-228) in 17 most frequently used cigarette brands in Serbia and corresponding effective doses due to smoke inhalation are presented. The mean annual effective doses for Pb-210 and Po-210 were estimated to be 47.3 and 724 A mu Sv y(-1) for Pb-210 and Po-210, respectively. Serbia currently has the highest smoking rate in the world. The results of this study indicate the high contribution of the annual effective dose due to smoke inhalation to the total inhalation dose from natural radionuclides. The more effective implementation of actions for reducing smoking prevalence in Serbia is highly needed.

AB  - Various particles and materials, including pollutants, deposited on urban surfaces are washed off by stormwater runoff during rain events. The interactions between the solid and dissolved compounds in stormwater runoff are phenomena of importance for the selection and improvement of optimal stormwater management practices aimed at minimizing pollutant input to receiving waters. The objective of this research was to further investigate the mechanisms responsible for the partitioning of heavy metals (HM) between the solid and liquid phases in urban stormwater runoff. The research involved the collection of samples from urban asphalt surfaces, chemical characterization of the bulk liquid samples, solids separation, particle size distribution fractionation and chemical and physicochemical characterization of the solid phase particles. The results revealed that a negligible fraction of HM was present in the liquid phase (less than 3% by weight), while there was a strong correlation between the total content of heavy metals and total suspended solids. Examinations of surface morphology and mineralogy revealed that the solid phase particles consist predominantly of natural macroporous materials: alpha quartz (80%), magnetite (11.4%) and silicon diphosphate (8.9%). These materials have a low surface area and do not have significant adsorptive capacity. These materials have a low surface area and do not have significant adsorptive capacity. The presence of HM on the surface of solid particles was not confirmed by scanning electron microscopy and energy dispersive X-ray microanalyses. These findings, along with the results of the liquid phase sample characterization, indicate that the partitioning of HM between the liquid and solid phases in the analyzed samples may be attributed to precipitation processes.

AB  - Natural minerals, such as quartz, clinoptilolite and calcite, are useful as sorbents for various applications, but their content of heavy metals ions is the most problematic obstacle to their application. Before their (re)use, the minerals must be purified. In this work, the subject was desorption of lead from a natural multi-component mineral sample consisting of a mixture of silicates (mainly quartz and clinoptilolite) and calcite formations. Besides deionized water, different extraction solutions were tested: NaCl, KCl, CaCl2, MgCl2, HCl, HNO3, EDTA, EDTA/HCl, EDTA/NaOAc-HOAc, HOAc, NaOAc and NaOAc-HOAc. Several parameters were varied in order to obtain the optimal conditions for the desorption process: the concentration of the extraction solution, the ratio of the mass of the sample and volume of the extractant, and the pH value of the suspension. The best purification effect in one desorption cycle was obtained when 0.1 M EDTA, at a pH value of 3.5 (0.2 M EDTA was mixed with 0.01 M acetic buffer, at pH value 3.0, in ratio 1:1) was applied. Sequential extraction (5 consecutive iterations) was performed to provide a more efficient purification process. The lead content (58.20 mg/kg) was decreased by: 20% (using HOAc), 21% (using EDTA) and by more than 50% (using EDTA/NaOAc-HOAc). The pH value and conductivity were measured at all critical points to clarify the mechanism of the desorption process. The formation of Pb-EDTA complex is the result of two parallel phenomena, complexing and ion-exchange. An enhanced adsorption capacity and an improved microelement profile for the purified samples were also attained. The mineralogical and radiochemical performances of the sample were determined by the X-ray diffraction and gamma spectrometry techniques. Microelement analyses of the native and purified samples were performed by inductively coupled plasma optical emission spectroscopy (ICP-OES). (C) 2014 Elsevier B.V. All rights reserved.

AB  - This study is focused on the surface modifications of the materials that are used for antimicrobial water treatment. Sorbents of different origin were activated by Ag+-ions. The selection of the most appropriate materials and the most effective activation agents was done according to the results of the sorption and desorption kinetic studies. Sorption capacities of selected sorbents: granulated activated carbon (GAC), zeolite (Z), and titanium dioxide (T), activated by Ag+-ions were following: 42.06, 13.51 and 17.53 mg/g, respectively. The antimicrobial activity of Ag/Z, Ag/GAC and Ag/T sorbents were tested against Gram-negative bacteria E. coli, Gram-positive bacteria S. aureus and yeast C. albicans. After 15 min of exposure period, the highest cell removal was obtained using Ag/Z against S. aureus and E. coli, 98.8 and 93.5%, respectively. Yeast cell inactivation was unsatisfactory for all three activated sorbents. The antimicrobial pathway of the activated sorbents has been examined by two separate tests - Ag+-ions desorbed from the activated surface to the aqueous phase and microbial cell removal caused by the Ag+-ions from the solid phase (activated surface sites). The results indicated that disinfection process significantly depended on the microbial-activated sites interactions on the modified surface. The chemical state of the activating agent had crucial impact to the inhibition rate. The characterization of the native and modified sorbents was performed by X-ray diffraction technique, X-ray photoelectron spectroscopy and scanning electron microscope. The concentration of adsorbed and released ions was determined by inductively coupled plasma optical emission spectroscopy and mass spectrometry. The antimicrobial efficiency of activated sorbents was related not only to the concentration of the activating agent, but moreover on the surface characteristics of the material, which affects the distribution and the accessibility of the activating agent.

AB  - Among radionuclides in the soil deposited after Chernobyl accident, Cs-137 poses considerable environmental and radiological problemdue to its relatively long half-life (30.17 gamma), its abundance in the fallout, high mobility and similarity to potassium as the major plant nutrient. In this study the samples of undisturbed surface soil (n = 250) were taken from 70 regions in Belgrade, during 2006-2010. The specific activities of Cs-137 were measured by gamma-ray spectrometry. Based on obtained results, the external effective dose rates were calculated according to the internationally accepted activity to dose rate conversion equations. The specific activities of Cs-137 were geographically mapped. The presence of Cs-137 has been detected in all soil samples, with high variability of its specific activity, ranging from 3 to 87 Bq kg(-1).The mean specific activity of Cs-137 was 23 Bq kg(-1) and the corresponding absorbed dose was 1.5 nSv h(-1). The observed range reflects the inhomogeneity of the deposition process following the Chernobyl accident. It could also be attributed to topographic differences and spatial differences in physicochemical and biological soil properties, soil type and vegetation cover. The results of the present study could be valuable database for future estimations of the impact of radioactive pollution.
