Ibiro ntaramakuru Xinhua, Wellington, ku ya 24 Nzeri (Umunyamakuru Lu Huaiqian na Guo Lei) Itsinda ry’ubushakashatsi ryaturutse muri kaminuza ya Otago muri Nouvelle-Zélande ryasanze bitatu bya kane by’amafi arenga 150 yo mu gasozi yafatiwe mu nyanja mu majyepfo ya Nouvelle-Zélande arimo microplastique .
Bakoresheje microscopi na Raman spectroscopy kugira ngo bige ku ngero 155 z’amafi 10 y’ingenzi yo mu nyanja y’ubucuruzi yafatiwe ku nkombe za Otago mu gihe kirenga umwaka, abashakashatsi basanze 75 ku ijana by’amafi yize arimo microplastique, ikigereranyo cya 75 kuri buri fi.Habonetse uduce duto twa microplastique 2.5, naho 99,68% by'ibice bya pulasitiki byagaragaye byari bito munsi ya mm 5 z'ubunini.Microplastique fibre nubwoko busanzwe.
Ubushakashatsi bwerekanye urugero rwa microplastique mu mafi atuye mu burebure butandukanye mu mazi yavuzwe haruguru, byerekana ko microplastique iba hose mu mazi yizwe.Abashakashatsi bavuga ko hakenewe ubundi bushakashatsi kugira ngo hamenyekane ingaruka z’ubuzima bw’abantu n’ibidukikije biterwa no kurya amafi yanduye.
Microplastique muri rusange yerekeza ku bice bya plastike bitarenze mm 5 z'ubunini.Ibimenyetso byinshi kandi byinshi byerekana ko microplastique yanduye ibidukikije byo mu nyanja.Iyo myanda imaze kwinjira murwego rwibiryo, izasubira kumeza yumuntu kandi ibangamire ubuzima bwabantu.
Ibyavuye mu bushakashatsi byatangajwe mu nomero nshya y’Ubwongereza bw’imyanda ihumanya.
