Abstract
U ovom radu istraţivan je početni obraštaj na četiri vrste plastičnih vrećica: polivinil klorid (PVC), polietilen visoke gustoće (HDPE), polietilen niske gustoće (LDPE) i dvije vrste biorazgradivih vrećica, jedna koja sadrţi EPI aditiv (Earth Rated®) dok je druga na bazi škroba (Profissimo kompostabilna). Eksperiment je proveden tijekom ljetne i zimske sezone. Vrijeme potrebno da plastika počne tonuti je 11 dana u ljetnoj sezoni i 13 dana u zimskoj sezoni. Na pet različitih vrsta plastike je utvrĎena prisutnost 38 svojti praţivotinja (od kojih 36 svojti dijatomeja, jedna vrsta cilijata i jedna vrsta dinoflagelata). Razlika u broju svojta i biovoluemenu izmeĎu sezona je zanemariva, međutim razlika u prosječnoj gustoći stanica po sezoni je 15 puta veća ljeti (20509 stanica/cm2) nego zimi (1342 stanica/cm2). Najbrojnije svojte su male dijatomeje reda Pennales. UtvrĎena je statistički značajna razlika izmeĎu materijala PELD i ostalih vrsta plastičnih materijala po morfologiji i biovolumenu svojti.
Abstract (english)
The initial biofilm formation on four types of plastic was investigated. The plastic bags used in this experimentwere made from: polyvinyl chloride (PVC), high-density polyethylene (HDPE), low-density polyethylene (LDPE) and two biodegradable types, one containing an EPI additive (Earth Rated) and the other was starch based (Profissimo compostable). The experiment was carried outduring two seasons (summer and winter). The plastic started sinking after 11 days in the summer season and 13 days in the winter.On five different types of plastic 38 taxa of protozoa were identified (36 diatom taxa, one taxa of ciliate and one of dinoflagellate). The difference in the number of taxa and biovolumen per season is negligible. However, the difference in total abundance per season was significant, in the summer (20509 cells/cm2) was 15 times higher than in winter (1342 cells/cm2). The most abundant species were small diatoms from Pennales order. A statistically significant difference was found between PELD and other plastic materials regarding the morphology and biovolume of the taxa.
