Abstract
Antiparazitici se ubrajaju u nova onečišćivala vode s obzirom da je nedavno istaknut njihov potencijalan negativan utjecaj na okoliš. Izlučevinama životinja i ljudi lako dospijevaju u tla i vodu gdje imaju negativan utjecaj na ostale organizme. Također, prisutstvo mikroplastike u vodama je rastući problem s utvrđenim negativnim utjecajima na zdravlje ljudi i životinja. Mikroplastika je veličine manje od 5 nm te iznimno heterogenog sastava čime je njena učinkovita eliminacija iz vode velik izazov te čest predmet istraživanja. Kvantifikacija i identifikacija antiparazitika albendazola, mebendazola te febantela u uzorcima provedena je tekućinskom kromatografijom visoke djelotvornosti. Potrebne su daljnje analize da bi utvrdili o kojim se razgradnim produktima radi. Razgradnja antiparazitika se nastojala potaknuti mehaničkim miješanjem u prisutstvu vodikova peroksida te natrijeva hipoklorita. Provedeni su eksperimenti fotolize primjenom umjetnog Sunčevog zračenja kako bi se ispitala mogućnost razgradnje antiparazitika djelovanjem fotona. Ovi simulirani uvjeti su ispitani i u prisutstvu mikroplastike kako bi se pratio njen moguć utjecaj na njihovu razgradnju. Rezultati su pokazali različit postotak razgradnje između tri navedena antiparazitika. Količina razgradnih produkata se razlikuje ovisno o ispitivanom antiparazitiku, pH-vrijednosti te koncentraciji korištenog reagensa. Prisutstvo mikroplastike u simuliranoj otpadnoj vodi nije utjecalo na promjenu razgradnje antiparazitika neovisno o provođenom testu.
Abstract (english)
Antiparasitics are among the new water pollutants, given that their potential negative impact on the environment has recently been highlighted. By secretions of animals and humans, they can easily reach the soil and water where they have negative impact on other organisms. Also, the presence of microplastics in water is a growing problem with confirmed negative effect on human and animal health. Microplastics are smaller than 5 nm in size and have an extremely heterogeneous composition, which makes its effective elimination from water a great challenge and frequent subject of research. In this research, using HPLC equipment, the composition of degradation products according to the similiraties of the absorption spectrum was analysed for the antiparasitics albendazole, mebendazole and febantel. Degradation of antiparasitics was attempted by mechanical mixing in the presence of hydrogen peroxide and sodium hypochlorite. Solar radiation was also simulated in order to research the possibility of antiparasitics degradation by the action of photons. These simulated conditions were also examined in the presence of microplastics to monitor its possible impact on their degradation. The results showed different percentage degradation between the three mentioned antiparasitics. The amount of degradation products varies depending on the tested antiparasitic, pH value and concentration of the used reagent. Presence of microplastics in the simulated wastewater did not affect the change in degradation of antiparasitics regardless of the test performed.
