AB  - A dispersive solid-phase microextraction (DSPME) sorbent consisting of poly(1,6-hexanedi-ol diacrylate)-based polymer microspheres, with embedded graphene microparticles (poly(HDDA)/g-raphene), was synthesized by microfluidic emulsification/photopolymerization and characterized by optical microscopy and X-ray fluorescence spectrometry. This sorbent was applied for simple, fast, and sensitive vortex-assisted DSPME of rare earth elements (RREs) in coal fly ash (CFA) leachate, prior to their quantification by inductively coupled plasma mass spectrometry (ICP-MS). Among nine DSPME variables, the Plackett–Burman screening design (PBD), followed by the central composite optimization design (CCD) using the Derringer desirability function (D), identified the eluent type as the most influencing DSPME variable. The optimum conditions with maximum D (0.65) for the chelating agent di-(2-ethylhexyl) phosphoric acid (D2EHPA) amount, the sorbent amount, the eluting solvent, the extraction temperature, the centrifuge speed, the vortexing time, the elution time, the centrifugation time, and pH, were set to 60 µL, 30 mg, 2 M HNO3, 25◦ C, 6000 rpm, 1 min, 1 min, 5 min, and 4.2, respectively. Analytical validation of the DSPME method for 16 REEs (Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) in CFA leachate samples estimated the detection limits at the low ppt level, the recovery range 43–112%, and relative standard deviation within ± 22%. This method was applied to a water extraction procedure (EP) and acetic acid toxicity characteristic leaching procedure (TCLP) for leachate of CFA, from five different coal-fired thermoelectric power plants. The most abundant REEs in leachate (20 ÷ 1 solid-to-liquid ratio) are Ce, Y, and La, which were found in the range of 22–194 ng/L, 35–105 ng/L, 48–95 ng/L, and 9.6–51 µg/L, 7.3–22 µg/L, 2.4–17 µg/L, for EP and TCLP leachate, respectively. The least present REE in TCLP leachate was Lu (42–125 ng/L), which was not detected in EP leachate.

AB  - A survey was made to analyze the geostatistical (GIS) distribution of the health risk of toxic
trace metal(loid)s in the industrial soil located in the facility of an abandoned paints manufacturing company. A total of eighty surface soil samples were collected, and their concentrations determined. The mean concentration values of the elements were 7.8; 2.7; 55; 49;
0.21; 56; 114; and 239 mg/kg for As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn, respectively. There was
no non-carcinogenic health risk from the soil samples for adults, but it was hazardous soil
for children with the excess lifetime cancer risk (ELCR) values exceeding the reference value
of 10-4 for all studied samples. Most contributing toxic metal(loid)s to non-carcinogenic risk
were Cr and As, whereas Pb and As were most responsible for cancer risk. Geospatial mapping of the hazard index (HI) and ELCR localized different hotspots seriously polluted by
toxic metal(loid)s, which pose a significant risk in the area. These hotspots coincided with
the evidence of transport-related activities and spillage of chemicals in the past. This GIS
spatial distribution study could be a valuable aid in remediation planning.

AB  - The survey results of an atmospheric deposition of major, minor and trace elements
using the moss biomonitoring technique are given for the vicinity of the largest
thermal power plant in Serbia. The mosses of genus Brachythecium sp. and species
Kindbergia praelonga (Hedw) Ochyra, both pleurocarpous, were favoured. The concentrations of 22 elements were determined in moss samples using different spectrometric
techniques depending on the sensitivity needed. Elevated concentrations of As, Cd, Co,
Hg, Ni and V were found in the vicinity of the thermal power plant. The results obtained
were chemometrically treated by cluster analysis, which grouped the elements into
three clusters based on common patterns in their concentrations.

AB  - The content of trace elements (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb and Zn) in surface soils in the area surrounding the largest coal-fired power plant in Serbia was determined to assess the contribution of emissions to pollution. Analysis of mutual associations between the trace elements and their correlation with soil particle size fractions indicated anthropogenic origin at most sampling sites. Enrichment factor analysis confirmed these findings. Common patterns in trace element concentrations of the analysed soils were identified by hierarchical cluster analysis. Explanatory spatial analysis, used for characterization and mapping of spatial variability patterns, revealed the highest concentrations of trace elements in areas in predominant wind directions.

AB  - The concentrations of Cu, Zn, Mn, Fe, K, Ca, Mg, Al, Ba and B in 26 herbal drugs of special importance in phytopharmacywere studied. Flame atomic absorption and emission spectrometry (FAAS, FAES), as well as inductively coupled plasma atomic emission spectrometry (ICP-AES), were applied in this work. The whole procedure, from sample preparation, via dissolution, to measurements, was validated by using CRM (NIST 1573a-tomato leaves), and the obtained recovery values are in the range from 91 to 102%. Drug samples originated from medicinal plants cultivated in Serbia contained Cu (4.47-14.08 mg kg(-1)), Zn (8.4-54.5 mg kg(-1)), Mn (9-155 mg kg(-1)), Fe (47-546 mg kg(-1)), K (0.20-6.24%), Ca (0.18-1.84%), Mg (0.13-1.09%), Al (16-416 mg kg(-1)), Ba (11.70-84.83 mg kg(-1)) and B (5.1-118.7 mg kg(-1)). In order to get a better insight into the elemental patterns, a common chemometric approach to data evaluation was used. Four significant factors identified by principal component analysis (PCA) were attributed partly to the significant influential sources and high mobility of some elements thus referring to potential anthropogenic contamination as well.

AB  - The concentrations of the elements Cr, Pb, Cd, Zn, Ni, Mn, Cu and As in soil samples from industrial areas in Serbia were studied. The complexity of the data of eight elements in fifty-nine soil samples was reduced by principal component analysis. Three significant factors, in which 78% of the total variance in the data was found, were attributed to possible pollution sources. The crude and fuel oil burning, local smelters and exhaust emissions were shown to impact heavily the soil trace element profile, whereas no distinct soil type factor was observed. This approach, evidencing spatial relationship, enabled a differentiation between the soil samples originating from different areas.
