Abstract
Onečišćenje okoliša plastikom godinama je aktualan problem koji privlači pozornost ekologa, ali i šire opće javnosti. Obzirom na svoju osjetljivost, morskom okolišu se posebno pridaje pozornost po pitanju ovog problema. Cilj ovoga rada bio je utvrditi koliko se mikroplastike akumulira u najčešćoj komercijalnoj vrsti Jadranskog mora, točnije u oradi Sparus aurata. U Istarskoj županiji tijekom jeseni i proljeća uzorkovale su se jedinke orada za vrijeme mrijesta, a njihova probavila testirana su na prisutnost mikroplastike. Probavila suse otapala u otopini kalijeva hidroksida (KOH). Na posljetku razgrađena probavila su se promatrala pod mikroskopom. U probavilima je pronađeno 77 čestica u jesenskom periodu, te 17 čestica u proljetnom periodu. Najčešći oblik čestica bile su niti (eng. fiber). Prema boji najprisutnije su niti crne boje, čak njih 53 %, dok je pronađeno manje plavih 22 % i 14 % zelenih čestica. Determinacija glavnih izvora onečišćenja pojedinih prostora kao i bolje razumijevanje mehanizma ingestije mikroplastike kod riba trebaju predstavljati glavni fokus u budućim istraživanja.
Abstract (english)
Environmental pollution with plastic has been a current problem for years, attracting the attention of ecologists, but also of the general public. Due to its sensitivity, the marine environment receives special attention regarding this problem. The aim of this work was to determine how much microplastic accumulates in the most common commercial species of the Adriatic Sea, more specifically in sea bream Sparus aurata. In the County of Istria, during the fall and spring, sea bream individuals were sampled during spawning, and their digestive tracts were tested for the presence of microplastics. Digestive tracts would be digested in potassium hydroxide (KOH) solution. Finally, the decomposed digesta would be observed under a microscope. 77 particles were found in the digestive tracts in the autumn period, and 17 particles. in the spring period. The most common form of particles found were fibers. According to the color, black threads are most present, as many as 53% of them, while less ,blue, with 22% and 14% green particles were found. The determination of the main sources of pollution in certain areas as well as a better understanding of the mechanism of microplastic ingestion by fish should be the main focus of future research.
