Iingxowa zeti zeplastiki zasimahla?Ewe, uyive kakuhle...
Umenzi we-Tonchant 100% yeplastiki yephepha lokucoca simahla kwiingxowa zeti,FUNDA OKUNGAKUMBI APHA
Ikomityi yakho yeti inokuba neebhiliyoni ezili-11 zamasuntswana eplastiki kwaye oku kungenxa yendlela ibhegi yeti eyenziwe ngayo.
Ngokophononongo lwakutsha nje lwaseKhanada kwiDyunivesithi yaseMcGill, ukufaka ingxowa yeti yeplastiki kwiqondo lobushushu obungama-95°C kukhupha malunga ne-11.6 yeebhiliyoni zeeplastiki zeplastiki – amaqhekeza amancinane eplastiki aphakathi kwe-nanometer ezili-100 kunye neemilimitha ezi-5 ngobukhulu – kwikomityi enye.Xa kuthelekiswa netyuwa, ngokomzekelo, ekwafunyaniswa ukuba ineplastiki, ikomityi nganye inobunzima obuphindwe kangangamawaka eplastiki, kwiimicrogram ezili-16 ikomityi nganye.
Ubukho obuninzi beeplastiki ezincinci kunye ne-nano-size kwindalo kunye nekhonkco lokutya kukukhathazeka okukhulayo.Nangona abathengi abanengqondo bekhuthaza ukucuthwa kweeplastiki ezisetyenziswa kanye, abanye abavelisi benza ukupakishwa okutsha kweplastiki ukuthatha indawo yokusetyenziswa kwephepha lemveli, elifana neengxowa zeplastiki zeti.Injongo yolu phononongo yayikukumisela ukuba ngaba iingxowa zeplastiki zeplastiki zinokukhulula i-microplastics kunye / okanye i-nanoplastics ngexesha lenkqubo eqhelekileyo yokunyuka.Sibonisa ukuba ukukhwela ingxowa yeti yeplastiki enye kwiqondo lobushushu bokwenza utywala (95 °C) kukhupha malunga ne-11.6 yeebhiliyoni ze-microplastics kunye ne-3.1 yeebhiliyoni zee-nanoplastics kwikomityi enye yesiselo.Ukubunjwa kwamasuntswana akhutshiweyo kuhambelana neengxowa zokuqala zeti (inayiloni kunye nepolyethylene terephthalate) kusetyenziswa i-Fourier-transform infrared spectroscopy (FTIR) kunye ne-X-ray photoelectron spectroscopy (XPS).Amanqanaba e-nylon kunye ne-polyethylene terephthalate particles ekhutshwe kwi-teabag package yimiyalelo emininzi yobukhulu obuphezulu kunemithwalo yeplastiki echazwe ngaphambili kwezinye ukutya.Uvavanyo lokuqala lwetyhefu ye-invertebrate lubonisa ukuba ukuvezwa kuphela ngamasuntswana akhutshiweyo kwiingxowa zeeti kubangele iziphumo zokuziphatha ezixhomekeke kumthamo kunye nophuhliso.
