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

AB  - 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%).

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  - 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.

AB  - The Republic of Serbia generates the majority of its electricity at the thermal power plants (TE) Nikola Tesla, Kolubara, and Kostolac. 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.

Two raw materialscomposed of SiO2, Al2O3 and Fe2O3, were analyzed. According to the textural classification the tested materials belong to sandy loam and loamy sand. In this research, X-ray diffraction analysis (XRD) and Fourier-Transform infrared spectroscopy (FTIR) were used for structural characterization of the materials. The process of adsorption of Pb2+ ions onto natural materials was conducted in a batch system. In order to determine optimal conditions, the mass of the adsorbent and the pH value of the solution were varied. Sandy loam and loamy sand have shown high efficiency for removing Pb2+ions from aqueous solution, without previous chemical modification. The efficiency of removal of lead ions on sandy loam and loamy sand is 88.2% and 80.2%, respectively, under optimal conditions (Ci(Pb2+)=100 μg L-1, mads=10 mg and pH 5). This study confirms that natural materials based on metal oxides can be used as effective adsorbents toremove cationic species of heavy metals from water systems.

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%).

AB  - Due to their excellent characteristics, such as chemical inertness, mechanical resistance, low Young's modulus, high corrosion resistance, and outstanding biocompatibility, titanium and its alloys are the most used metallic materials for biomedical applications. In dental practice, these materials have demonstrated success as biomedical devices which are used for repairing and replacing failed hard tissue. However, the oral cavity is constantly subjected to the changes in the pH value changes and such an environment is strongly corrosive for titanium dental implants. The objective of this study was to examine ion release from commercially pure titanium (cpTi) in artificial saliva with different pH values (4.0, 5.5 and 7.5). The concentrations of released titanium ions were determined after 1, 3 and 6 weeks using Inductively Coupled Plasma - Mass Spectrometry. The results indicate that the ion release from commercially pure titanium in the artificial saliva is dependent both on the pH of artificial saliva and duration of immersion.
