Amashashi yicyayi yubusa?Yego, wumvise ubwo burenganzira…

Tonchant uruganda rukora 100% yubusa ya filteri yubusa ya teabags,YIGA BYINSHI HANO

Igikombe cyawe cyicyayi gishobora kuba kirimo miliyari 11 za microplastique kandi ibi biterwa nuburyo umufuka wicyayi ukorwa.

Ubushakashatsi buherutse gukorwa n’Abanyakanada muri kaminuza ya McGill, bwerekana ko umufuka w’icyayi wa pulasitike ku bushyuhe bwa dogere 95 ° C urekura microplastique igera kuri miliyari 11,6 - uduce duto twa plastiki hagati ya nanometero 100 na milimetero 5 mu bunini - mu gikombe kimwe.Ugereranije n'umunyu, kurugero, wasangaga nanone irimo plastike, buri gikombe kirimo ubwinshi bwibihumbi bya plastike, kuri microgramo 16 kuri buri gikombe.

Kwiyongera kwa plastike ya micro- na nano nini mubidukikije no murwego rwibiryo birahangayikishije.Nubwo abaguzi batekereza bashimangira kugabanya plastike imwe rukumbi, abayikora bamwe barimo gukora ibipapuro bishya bya pulasitike kugirango basimbuze impapuro gakondo, nk'icyayi cya plastiki.Icyari kigamijwe muri ubu bushakashatsi kwari ukumenya niba icyayi cya pulasitike gishobora kurekura microplastique na / cyangwa nanoplastike mu gihe gisanzwe cyo guhagarara.Twerekana ko gushira icyayi kimwe cya pulasitike ku bushyuhe bwo hejuru (95 ° C) kirekura microplastique hafi miliyari 11,6 na nanoplastike miliyari 3.1 mu gikombe kimwe cy’ibinyobwa.Ibigize ibice byasohotse bihujwe na teabags yumwimerere (nylon na polyethylene terephthalate) ukoresheje Fourier-transform infrared spectroscopy (FTIR) na X-ray fotoelectron spectroscopy (XPS).Urwego rwa nylon na polyethylene terephthalate zasohotse mu gipfunyika cya teabag ni ibintu byinshi byerekana ubunini burenze imitwaro ya pulasitike yavuzwe mbere mu bindi biribwa.Isuzuma ryambere ryimbaraga zidafite ubumara bwerekana ko guhura nuduce duto twavuye mu cyayi byateje ingaruka ziterwa nimyitwarire niterambere.
