I ka hoʻohana ʻana i ka microscopy a me Raman spectroscopy e aʻo ai i 155 mau laʻana o 10 mau iʻa kai koʻikoʻi i hopu ʻia ma waho o ke kapakai ʻo Otago ma mua o hoʻokahi makahiki, ua ʻike nā mea noiʻi he 75 pākēneka o nā iʻa i aʻo ʻia he microplastics, he awelika o 75 no kēlā me kēia iʻa.Ua ʻike ʻia nā ʻāpana microplastic 2.5, a ʻoi aku ka liʻiliʻi o 99.68% o nā ʻāpana plastik i ʻike ʻia ma mua o 5 mm ka nui.ʻO nā fiber microplastic ka ʻano maʻamau.
Ua ʻike ka haʻawina i nā pae like ʻole o nā microplastics i nā iʻa e noho ana ma nā hohonu like ʻole i nā wai i ʻōlelo ʻia ma mua, e hōʻike ana aia nā microplastics i nā wahi āpau i nā wai i aʻo ʻia.Ua ʻōlelo ka poʻe noiʻi he pono ka noiʻi hou ʻana e hoʻoholo i nā pilikia i ke olakino kanaka a me ke kaiaola mai ka ʻai ʻana i nā iʻa i hoʻopaʻa ʻia i ka plastic.
ʻO ka microplastics ka mea maʻamau i nā ʻāpana plastik liʻiliʻi ma mua o 5 mm ka nui.Hōʻike a ʻoi aku ka nui o nā hōʻike e hoʻohaumia ana nā microplastics i ke kaiaola kai.Ma hope o ke komo ʻana o kēia mau ʻōpala i ke kaulahao meaʻai, e kahe hou lākou i ka papaʻaina kanaka a hoʻopilikia i ke olakino kanaka.
Ua paʻi ʻia nā hopena noiʻi ma ka pukana hou o ka UK's Marine Pollution Bulletin.
