I-Arhente yeNdaba ye-Xinhua, i-Wellington, i-24 Septemba (i-Reporter Lu Huaiqian kunye noGuo Lei) Iqela lophando elivela kwiYunivesithi yase-Otago eNew Zealand lifumene ukuba iikota ezintathu zeentlanzi zasendle ezingaphezu kwe-150 ezibanjwe kwindawo yolwandle kumzantsi weNew Zealand ziqulethe i-microplastics. .
Ukusebenzisa i-microscopy kunye ne-Raman spectroscopy ukufunda iisampulu ze-155 ze-10 ezibalulekileyo ezithengiswayo zeentlanzi zaselwandle ezibanjwe kunxweme lwase-Otago ngaphezu konyaka, abaphandi bafumanisa ukuba i-75 pesenti yentlanzi ephononongwayo iqulethe i-microplastics, i-avareji ye-75 yentlanzi nganye.I-2.5 i-microplastic particles yafunyanwa, kwaye i-99.68% yeengqungquthela zeplastiki ezichongiweyo zazincinci kune-5 mm ngobukhulu.Iifibers zeMicroplastic lolona hlobo luxhaphakileyo.
Uphononongo lufumene amanqanaba afanayo e-microplastics kwiintlanzi ezihlala kubunzulu obuhlukeneyo kumanzi akhankanywe ngasentla, ebonisa ukuba i-microplastics ikhona yonke indawo kumanzi afundwayo.Abaphandi bathi uphando olongezelelweyo luyimfuneko ukufumanisa umngcipheko kwimpilo yabantu kunye ne-ecology ekutyeni intlanzi engcolileyo yeplastiki.
IMicroplastics ngokubanzi ibhekisa kumasuntswana eplastiki amancinci kune-5 mm ngobukhulu.Ubungqina obuninzi bubonisa ukuba ii-microplastics zingcolise imo engqongileyo yolwandle.Emva kokuba le nkunkuma ingene kwikhonkco lokutya, iya kuqukuqela ibuyele etafileni yomntu kwaye ibeka impilo yabantu engozini.
Iziphumo zophando zapapashwa kumbandela omtsha we-Bulletin yase-UK yoNgcoliseko lwaseLwandle.
