AB  - Unappropriated disposing of unused drugs leads to an increase in their concentration in the
environment. Furthermore, wastewater treatment plants are not sufficient to prevent the
transport of drugs. Microplastics (MPs), which are also recognized as important pollutants,
can be divided into primary and secondary. The primary MPs are produced for commercial
purposes, while the secondary MPs are formed by the decomposition of plastic residues.
The hydrophobic nature and large specific surface area of MPs facilitate pollutants
binding. Animals misunderstand MPs for food and consume it, which could have harmful
health impacts because both MPs and adsorbed pollutants are ingested. In this paper, the
adsorption of the selected drugs - azithromycin, carbamazepine, sulfamethoxazole, and
diclofenac on low-density polyethylene (LDPE), polyamide (PA), and poly(ethylene
terephthalate) (PET) microplastics are presented. The experiment showed that drugs bind
best to PA and that azithromycin has the highest binding affinity.
AB  - Neadekvatno odlaganje neiskorišcenih lekova dovodi do povecanja njihove koncentracije u
životnoj sredini. Pored toga, postrojenja za precišcavanje otpadnih voda nisu dovoljna
barijera za sprecavanje transporta lekova. Mikroplastika (MP), koja je tako e detektovana
kao bitan polutant, može se podeliti na primarnu i sekundarnu. Primarna se proizvodi za
komercijalne svrhe, a sekundarna nastaje razgradnjom plasticnih ostataka. Hidrofobna
priroda i velika specificna površina MP olakšava adsorpciju polutanata na ove materijale.
Životinje mešaju MP sa hranom i unose je u svoj organizam, što može imati negativni
uticaj na njihovo zdravlje, jer se tako unose i MP i adsorbovani polutanti. U ovom radu je
prikazana adsorpcija odabranih lekova - azitromicina, karbamazepina, sulfametoksazola i
diklofenaka na sledecim vrstama mikroplastike - polietilenu niske gustine (LDPE),
poliamidu (PA) i poli(etilen tereftalatu) (PET). Eksperiment je pokazao da se lekovi
najbolje vezuju za PA, kao i da azitromicin ima najveci afinitet vezivanja.

AB  - This paper examines the effects of structural-textural characteristics of sulfide minerals on their leaching from polymetallic concentrates with sulfuric acid and hydrogen peroxide solutions. The polymetallic concentrate was obtained by flotation of polymetallic ore from the Rudnik deposit in Serbia. X-ray diffraction (XRD), qualitative and quantitative mineralogical, scanning electron microscopy (SEM/EDX), and chemical analyses were used to characterize the polymetallic concentrate and leach residue. The polymetallic concentrate contained chalcopyrite, galena, sphalerite, pyrrhotite, and quartz. The total content of sulfide minerals was 69.5%, and the occurrence of free sulfide mineral grains was about 60.9%. The comprehensive thermodynamic analysis was done by HSC Chemistry® package 9.9.2.3 to determine optimal experimental leaching conditions. Chalcopyrite, sphalerite, and pyrrhotite oxidized during leaching, and dissolution occurred. The oxidized galena remains in the solid residual as insoluble anglesite. Also, elemental sulfur and unleached minerals of copper, zinc, and iron were found in the leach residues. It was found that the structural assembly of sulfide minerals in the leach residue is very favorable and that undissolved sulfide grains are primarily present in free form. Accordingly, there was no reason to reduce the leaching rate with time. The presence of elemental sulfur and anglesite formed in the leaching process and precipitated on the surface of mineral grains was confirmed by XRD, quantitative and qualitative mineralogical analysis, and SEM/EDX.
