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.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
