Abstract
Čestice plastike manje od 5 mm nazivaju se mikroplastikom, a mogu se pronaći u atmosferi, tlu, morskom i slatkovodnom okolišu. Problemu mikroplastike značajnije se pristupilo u posljednjem desetljeću nakon što je količina mikroplastike u okolišu postala zabrinjavajuća. Čestice mikroplastike imaju velik i štetan utjecaj na morske organizme, odnosno na njihove fiziološke funkcije. Razvijene su brojne metode za ekstrakciju mikroplastike iz tkiva različitih organizama pa tako i školjkaša. U sklopu ovog istraživanja uspoređene su tri metode ekstrakcije iz dagnje Mytilus galloprovincialis: ekstrakcija iz tkiva pomoću kalijevog hidroksida, dušične kiseline te vodikovog peroksida. Tkivo se najbrže razgradilo u kalijevoj lužini na 60˚C, zatim u dušičnoj kiselini na 60˚C. Za razgradnju tkiva u vodikovom peroksidu bilo je potrebno više vremena, međutim, svaka od triju metoda pokazala se uspješnom.
Abstract (english)
Plastic particles smaller than 5 mm are called microplastics, and can be present in atmosphere, ground, freshwater and marine water. The microplastic problem became more important in last decade because quantity rates are quite worrying. Microplastic particles have huge and destructive effects on marine organisms, relatively on their physiology functions. There are more methods for microplastic extraction from tissues of different organisms especially from mussels. In this research are used three methods for extraction microplastics from tissue of mussel Mytilus galloprovincialis: extraction from tissue with potassium hydroxide, nitric acid, hydrogen peroxide. Tissue has been faster degradated with potassium hydroxide on temperature 60˚C, after that in nitric acid also on 60˚C. It takes longer time for tissue degradation in hydrogen peroxide, however, any of these three methods has showed succesfull.
