Kuki uhitamo igikapu fibre yicyayi?

Vuba aha, ubushakashatsi bwakozwe na kaminuza ya McGill yo muri Kanada bwerekanye ko imifuka yicyayi irekura miliyari icumi za uduce duto twa plastike ku bushyuhe bwinshi.Bigereranijwe ko buri gikombe cyicyayi cyatetse muri buri mufuka wicyayi kirimo miliyari 11,6 za microplastique na miliyari 3.1 za nanoplastique.Ubushakashatsi bwasohotse mu kinyamakuru cyo muri Amerika cy’ubumenyi n’ikoranabuhanga ku bidukikije ku ya 25 Nzeri.
Bahisemo guhitamo imifuka ine yicyayi ya pulasitike: imifuka ibiri ya nylon n imifuka ibiri ya PET.By'umwihariko, PET irashobora gukoreshwa mubushyuhe bwa 55-60 ℃ mugihe kirekire, kandi irashobora kwihanganira ubushyuhe bwo hejuru bwa 65 ℃ nubushyuhe buke bwa - 70 ℃ mugihe gito, kandi ntigire ingaruka nke kumiterere yubukanishi kuri ubushyuhe bwo hejuru kandi buke.Fata icyayi, oza igikapu n'amazi meza, hanyuma wigane inzira yo guteka icyayi, hanyuma ushire igikapu kirimo amazi 95 ashyushye muminota 5.Biragaragara ko amazi duteka icyayi ari amazi abira, kandi ubushyuhe buri hejuru cyane kurenza urugero rwa PET.
Gutahura kwa McGill byerekana ko umubare munini wibice bya plastike bizasohoka mbere.Igikombe cyicyayi cyicyayi kirashobora kurekura microne zigera kuri miliyari 11,6 na miliyari 3.1 za nanometero za plastike!Byongeye kandi, niba ibyo bice bya pulasitike byasohotse bifite ubumara ku binyabuzima.Kugira ngo basobanukirwe n'uburozi bw’ibinyabuzima, abashakashatsi bifashishije ibihuru by’amazi, inyamaswa zidafite ubuzima, n’ikinyabuzima ntangarugero gikoreshwa mu gusuzuma uburozi bw’ibidukikije.Iyo hejuru yibikapu yicyayi, niko gukora amazi yo koga.Nibyo, ibyuma biremereye + plastike birutwa nibice bya plastiki byera.Amaherezo, isazi y'amazi ntabwo yapfuye, ariko yarahinduwe.Ubushakashatsi bwanzuye ko niba igikapu cya pulasitike yicyayi kigira ingaruka ku buzima bwabantu gikeneye ubundi bushakashatsi.
