Isihlungi Esinezindleko eziphansi Esihlanza Umoya Wokungcola Ezinhlayiyeni Ezincane

Udaba lokungcoliswa kwemvelo seluphenduke udaba olushisayo emhlabeni wanamuhla.Ukungcoliswa kwemvelo, ngokuyinhloko okubangelwa amakhemikhali anobuthi, kuhlanganisa ukungcoliswa komoya, amanzi, nenhlabathi.Lokhu kungcola akuphumeleli nje kuphela ekubhujisweni kwezinhlobonhlobo zezinto eziphilayo, kodwa nasekucekeleni phansi kwempilo yabantu.Amazinga okungcola andayo usuku nosuku adinga intuthuko engcono noma ukutholwa kobuchwepheshe ngokushesha.I-Nanotechnology inikeza izinzuzo eziningi zokuthuthukisa ubuchwepheshe obukhona bemvelo nokudala ubuchwepheshe obusha obungcono kunobuchwepheshe bamanje.Ngalo mqondo, i-nanotechnology inamakhono amathathu ayinhloko angasetshenziswa emikhakheni yendawo ezungezile, okuhlanganisa ukuhlanza (ukulungisa) nokuhlanza, ukutholwa kokungcola (inzwa nokutholwa), kanye nokuvimbela ukungcola.

Emhlabeni wanamuhla lapho izimboni zenziwe zesimanje futhi zathuthukiswa, indawo yethu igcwele izinhlobo ezihlukahlukene zokungcola ezikhishwa emisebenzini yabantu noma ezinqubweni zezimboni.Izibonelo zalokhu kungcola i-carbon monoxide (CO), i-chlorofluorocarbon (CFCs), izinsimbi ezisindayo (i-arsenic, i-chromium, i-lead, i-cadmium, i-mercury ne-zinc), ama-hydrocarbons, ama-nitrogen oxides, ama-organic compounds (i-volatile organic compounds nama-dioxin), i-sulphur dioxide kanye izinhlayiya.Imisebenzi yabantu, efana nowoyela, ukushiswa kwamalahle nokushiswa kwegesi, inamandla amakhulu okushintsha izinto ezikhishwayo ezivela emithonjeni yemvelo.Ngaphandle kokungcoliswa komoya, kukhona nokungcoliswa kwamanzi okudalwa yizici ezihlukahlukene, okuhlanganisa ukulahlwa kwemfucuza, ukuchithwa kukawoyela, ukuvuza kukamanyolo, imithi yokubulala ukhula nezibulala-zinambuzane, imikhiqizo ekhiqizwa yizimboni kanye nokushiswa nokukhipha izinto zokubasa ezimbiwa phansi.

Izinto ezingcolisayo zitholakala kakhulu zixutshwe emoyeni, emanzini nasenhlabathini.Ngakho, sidinga ubuchwepheshe obukwazi ukuqapha, ukubona futhi, uma kungenzeka, ukuhlanza ukungcola emoyeni, emanzini nasenhlabathini.Kulo mongo, i-nanotechnology inikeza izinhlobonhlobo zamakhono nobuchwepheshe bokuthuthukisa ikhwalithi yendawo ekhona.

I-Nanotechnology inikeza ikhono lokulawula udaba ku-nanoscale nokudala izinto ezinezici ezithile ezinomsebenzi othile.Ukuhlola okuvela kwabezindaba ezikhethiwe ze-European Union (EU) kubonisa ukuba nethemba eliphezulu ngokuqhathaniswa nesilinganiso samathuba/ingozi ehambisana ne-nanotechnology, lapho iningi lazo liye labalelwa ekuthuthukisweni kwezinga lempilo nempilo.

Umfanekiso 1. Umphumela we-European Union (EU) wenhlolovo yabantu: (a) ibhalansi phakathi kwamathuba okuqonda nezingozi ze-nanotechnology kanye (b) nezingozi ezicatshangelwayo zokuthuthukiswa kwe-nanotechnology.
