Kushandisa microscopy uye Raman spectroscopy kudzidza 155 samples ye10 yakakosha yehove dzemugungwa dzakabatwa pamhenderekedzo yeOtago kweanopfuura gore, vaongorori vakawana kuti 75 muzana yehove dzakadzidzwa dzaive nemamicroplastics, avhareji ye75 pahove.2.5 microplastic particles yakaonekwa, uye 99.68% yezvikamu zvepurasitiki zvakaonekwa zvaive zviduku kudarika 5 mm muhukuru.Microplastic fibers ndiyo yakajairika mhando.
Chidzidzo chacho chakawana mazinga akafanana e microplastics muhove dzinogara pakadzika kwakasiyana mumvura yambotaurwa, zvichiratidza kuti microplastics inowanikwa mumvura yakadzidza.Vatsvagiri vanoti kumwe kutsvagisa kwakakosha kuona njodzi kuhutano hwevanhu uye ecology kubva pakudya hove dzakasvibiswa nepurasitiki.
Microplastics kazhinji inoreva zvidimbu zvepurasitiki zvidiki pane 5 mm muhukuru.Humbowo hwakawanda hunoratidza kuti microplastics yakasvibisa nharaunda yegungwa.Mushure mekunge tsvina iyi yapinda mucheni yezvokudya, inoyerera ichidzokera patafura yevanhu uye ichiisa pangozi hutano hwevanhu.
