Abstract
U ovom radu provedena je karakterizacija i identifikacija mikroplastike pronađene u sedimentu plaže Zaglav na otoku Visu. Uzorkovanje i separaciju uzoraka proveo je Institut za oceanografiju i ribarstvo u Splitu. Karakterizacija mikroplastike izvršena je na 865 uzoraka s plaže Zaglav na otoku Visu. Uzorci su vizualno analizirani i svrstani prema obliku definiranim prema DeFishGear protokolu: filamenti, filmovi, fragmenti, granule, peleti i pjene. Svakom pojedinačnom uzorku je vizualno određena prozirnost i boja, a masa vaganjem na analitičkoj vagi. Površina i maksimalna dimenzija svakog ispitka određeni su upotrebom Digimizer programskog paketa. Identifikacija vrste polimernog materijala o kojem je riječ provedeno je za 865 uzoraka uz pomoć FTIR spektroskopije i diferencijalne pretražne kalorimetrije, dok su sitniji uzorci ostavljeni za analizu naprednijim tehnikama. Ustanovljeno je da su fragmenti najzastupljenija kategorija, a uzorci su većinom neprozirni i bijele boje, čestice promjera manje od 5 mm što ih svrstava u kategoriju mikroplastike. Najzastupljenija vrsta polimernog materijala je polipropilen, nakon kojeg slijede polietilen visoke gustoće i polietilen niske gustoće. Rezultati koji su dobiveni ovim istraživanjem ukazuju da najveći broj uzoraka sedimenta plaže Zaglav na otoku Visu potječe od nepropisno odložene jednokratne ambalaže.
Abstract (english)
This thesis shows characterization and identification of microplastic waste found in the Zaglav beach sediment on Vis island. Sampling and separation of samples was performed by the Institute of Oceanography and Fisheries in Split. Characterization of microplastic was performed on 865 specimens from the Zaglav beach on Vis island. Specimens were visually analysed and sorted into categories according to shape defined by DeFishGear protocol: filaments, films, fragments, granules, pellets and foams. Transparency and color of the individual specimens are visually determined and a mass was determined using an analytical balance. Area and maximum dimension were determined using software package Digimizer for image processing. Identification of the type of polymer material was performed by FTIR spectroscoopy and diferential scanning calorimetry, while other smaller specimens were left for the further analysis using more precisely methods. The most common category is fragments, spesimens are mostly white in color and opaque, particles less than 5mm in diameter which sorts them in category of microplastics. The most common type of polymer material is polypropylene, followed by polyethylene high density and polyethylene low density. Results obtained by this research show that most specimens from Zaglav beach originate from improperly discarded disposable packaging.
