Abafundi ababili bakha amagciwane adla ipulasitiki angasindisa amanzi ethu

Ubuchopho Ngemva Kokuthola

Abafundi baseVancouver, eBritish Columbia, bathola ukutholakala okuguquguqukayo, amagciwane adla ipulasitiki angashintsha isimo sokungcoliswa kwepulasitiki olwandle lwethu, okubangela ukufa kwezilwane zasolwandle ezingenakubalwa. Ubani owathola lepulasitiki edla amagciwane? UMiranda Wang noJeanny Yao oneminyaka engamashumi amabili nanye namashumi amabili nambili. Phakathi nonyaka wabo ophakeme esikoleni esiphakeme, laba bobabili babenombono, owawuzoxazulula inkinga yokungcola emifuleni yangakubo eVancouver. 

Abafundi bamenywe ukuthi baxoxe ngokuthola kwabo “ngephutha” futhi bazifunele udumo enkulumweni ye-TED ngo-2013. Ngokuhlola ukungcola okuvamile kwepulasitiki, bathole ukuthi ikhemikhali eyinhloko etholakala kupulasitiki, ebizwa ngokuthi i-phthalate,  yengezwa “ukwandisa ukuguquguquka, ukuqina. nokungafihli” kwamapulasitiki. Ngokusho kososayensi abasebasha, okwamanje “amakhilogremu ayizigidi ezingu-470 e-phthalate angcolisa umoya wethu, amanzi, nomhlabathi wethu.”

Ukuqhuma

Njengoba kwakukhona amazinga aphezulu kangaka e-phthalate emanzini abo aseVancouver, baveza umbono wokuthi kufanele kube namabhaktheriya aseguqukile ukuze asebenzise ikhemikhali. Besebenzisa lesi sakhiwo bathola amagciwane enza lokho kanye. Amagciwane abo aqondise ngokuqondile futhi aphule i-phthalate. Kanye namabhaktheriya, bangeza ama-enzyme esisombululo esiphinde siphule i-phthalate. Imikhiqizo yokugcina isikhutha, amanzi, notshwala. 

The Future

Yize njengamanje bephothula izifundo zabo zeziqu zabo emanyuvesi ase-USA, bobabili sebengabasunguli benkampani yabo, iBio Collection. Iwebhusayithi yabo, i-Biocollection.com, ithi maduze bazokwenza izivivinyo zensimu, okungenzeka ukuthi zizokwenziwa e-China ehlobo lika-2016. Eminyakeni emibili iqembu lihlela ukuba nenqubo yokuhweba esebenzayo.
