AB  - The occurrence of potentially toxic elements (PTEs), including twelve heavy metal(loid)s (Cd, Cr, Cu, Ni, Pb, Zn, Hg, As, Co, V, Fe, Mn), fluoride (F−), and nitrate (NO3−) was evaluated in groundwater in the copper mining and smelter area of Bor city (south Carpathian, eastern Serbia). Groundwater samples were analyzed to determine the extent of pollution, identify natural and anthropogenic input of PTEs, and estimate potential human health risks due to exposure to these substances. The results revealed that the groundwater in the study area was highly contaminated with PTEs, particularly Cu and Zn. Multivariate analysis supported the natural and anthropogenic origin of PTEs, with Fe, Mn, and F− classified as naturally occurring, NO3− resulting from agricultural activities, while other PTEs were linked to smelter/mining processes. Geospatial mapping discovered several hotspots with potential high non-cancer and cancer risks to humans through ingestion pathway. From the studied PTEs, As is the most health risk contributing toxic element. The source-specific probabilistic risk assessment indicated the most significant contribution to the hazard index and total cancer risk from accidental leakage of metallurgical wastewater and wastewater from open mine pits. Monte Carlo analysis identified the human body weight and the ingestion rate as the most sensitive risk parameters. The study underscores the need for stringent environmental management measures, emphasizing the critical role of source-specific risk assessments in mitigating potential hazards associated with metallurgical wastewater and open mine pits.

AB  - Molecularly imprinted polymers (MIPs) as materials with determined levels of selectivity and specificity for designated analytes have recently gained much attention in various application fields. However, with the growing adoption of green analytical chemistry (GAC) principles, it is essential to investigate the greenness of MIP synthesis and its subsequent application in sample preparation, as well as to evaluate the "green"nature of the developed analytical methodologies, such as dispersive solid-phase microextraction (DSPME). Accordingly, the main objective of this research was to evaluate the greenness of MIP-based glycidyl methacrylate synthesis and MIP use as a DSPME sorbent prior to high-performance liquid chromatography with mass spectrometry (HPLC-MS). The green perspective of MIP-DSPME prior to HPLC-MS was investigated using various analytical metric tools such as the Analytical Eco-Scale, the Green Analytical Procedure Index, and Analytical GREEnness (AGREE). Since these analytical tools are not fully implementable for the assessment of the greenness of the MIP synthesis, some alternative approaches were used to optimize the synthesis parameters to make the MIP DSPME sorbent as close as possible to the GAC principles. The calculated AGREE score (0.62) and 91 points in the Analytical Eco-Scale for the proposed DSPME technique using MIP indicated a high level of greenness.

AB  - Arsenic is a metalloid, which occurs in nature in various forms, but in
natural waters mainly in the form of pentavalent oxyanion of arsenate As(V) and
trivalent arsenite As(III), which dominates under anaerobic conditions. Arsenic
water pollution is a serious problem due to its pronounced negative impact on
human health. This paper describes the kinetic and equilibrium studies of the
sorption mechanism of oxyanion As(V) in monocomponent aqueous solutions on
a silanized magnetic amino-functionalized copolymer of glycidyl methacrylate
and ethylene glycol dimethacrylate m-Si-PGME-deta. It has been shown that the
sorption of As(V) on m-Si-PGME-deta is a rapid process, initially controlled by
ion diffusion rate through solution. After achieving the saturation of the sorbent
surface, the sorption rate decreases, because the sorption rate determines
the process of intraparticle pore diffusion. The maximum sorption capacity is
5.61 μmolˑg-1.
AB  - Arsen je metaloid, koji pripada IV periodi i 15. grupi periodnog sistema, široko rasprostranjen

petovalentnog oksianjona аrsenаta As(V) i trovalentnog аrsenita As(III) koji dominira u anaerobnim
uslovima. Zаgаđenje vode аrsenom predstavlja ozbiljan problem zbog izraženog negаtivnog efekta
ovog elementa nа ljudsko zdrаvlje. Zbog toga su za uklanjanje arsena iz otpadnih voda razvijene

ovom radu opisano je ispitivanje efikasnosti sorbenta na bazi silaniziranog magnetita i aminofunkcionalizovanog kopolimera glicidil metakrilata i etilen glikol dimetakrilata, m-Si-PGME-deta, za
uklanjanje petovalentnog oksianjona arsena iz vodenih rastvora. Mehanizam sorpcije oksianjona
As(V) na sorbentu m-Si-PGME-deta ispitan je praćenjem kinetičkih i ravnotežnih parametara u
monokomponentnim vodenim rastvorima. Kinetika sorpcije analizirana je primenom modela pseudoprvog i pseudo-drugog reda, Jelovičevog i modela unutarčestične difuzije (IPD). Ravnotežni podaci
analizirani su Lengmirovim, Frojndlihovim i Temkinovim modelima izotermi. Pokazalo se da je sorpcija
oksianjona As(V) na m-Si-PGME-deta brz proces koji je u početnoj fazi kontrolisan brzinom difuzije
jona u rastvoru, zbog čega i kinetika sorpcije u toj fazi odgovara modelu pseudo-drugog reda. Po
dostizanju saturacije površine sorbenta, dolazi do rapidnog opadanja brzine sorpcije jer postaje
dominantno vezivanje jona za aktivna mesta u unutrašnjosti sorbenta, kada proces unutarčestične
difuzije kroz pore sorbenta određuje brzinu vezivanja jona, što najbolje opisuje kinetički model
IPD. Ispitivanje ravnotežnih parametara pokazuje najbolje slaganje Frojndlihovog modela sa
eksperimentalnim podacima, iz čega se može zaključiti da na površini sorbenta postoje aktivna mesta
sa različitim energijama vezivanja jona. Maksimalan kapacitet sorpcije iznosi 5.61 µmolˑg-1.
