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

AB  - 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.
