Umbandela wongcoliso lwemekobume uye waba ngumbandela oshushu kwihlabathi lanamhlanje.Ungcoliso lwemekobume, ubukhulu becala olubangelwa yimichiza eyityhefu, luquka umoya, amanzi nongcoliso lomhlaba.Olu ngcoliseko aluphumeleli nje ekutshatyalalisweni kweentlobo ngeentlobo zezinto eziphilayo, kodwa nokonakala kwempilo yabantu.Amanqanaba ongcoliseko ayanda imihla ngemihla afuna uphuhliso olungcono okanye ukufunyanwa kobuchwepheshe ngokukhawuleza.I-Nanotechnology ibonelela ngeenzuzo ezininzi zokuphucula itekhnoloji ekhoyo yokusingqongileyo kunye nokudala itekhnoloji entsha ebhetele kuneteknoloji yangoku.Ngaloo ngqiqo, i-nanotechnology ineendlela ezintathu eziphambili ezinokuthi zisetyenziswe kwimimandla yendalo, kubandakanywa ukucoca (ukulungiswa) kunye nokuhlanjululwa, ukufunyanwa kwezinto ezingcolileyo (ukubona kunye nokufumanisa), kunye nokukhusela ukungcola.

Kwihlabathi lanamhlanje apho imizi-mveliso iphuculwe yaza yaphuculwa, imeko-bume yethu izaliswe ziintlobo ngeentlobo zongcoliseko oluphuma kwimisebenzi yabantu okanye kwiinkqubo zamashishini.Imizekelo yezi zinto zingcolisa icarbon monoxide (CO), chlorofluorocarbons (CFCs), iintsimbi ezinzima (arsenic, chromium, lead, cadmium, mercury nezinc), iihydrocarbons, nitrogen oxides, organic compounds (volatile organic compounds and dioxins), sulfur dioxide kunye iinxalenye.Imisebenzi yabantu, efana ne-oyile, amalahle kunye nokutsha kwerhasi, inamandla amakhulu okutshintsha izinto ezikhutshwayo ezivela kwimithombo yendalo.Ukongeza kungcoliseko lomoya, kukwakho nokungcoliseka kwamanzi okubangelwa zizinto ezahlukeneyo, kubandakanywa ukulahlwa kwenkunkuma, ukuchitheka kweoyile, ukuvuza kwezichumisi, imichiza yokubulala ukhula kunye nezibulali-zinambuzane, iimveliso zenkqubo yemizi-mveliso kunye nokutsha kunye nokutsalwa kwamafutha efosili.

Izinto ezingcolisayo zifumaneka zixutywe emoyeni, emanzini nasemhlabeni.Ngaloo ndlela, sifuna iteknoloji ekwazi ukubeka iliso, ukubona kwaye, ukuba kunokwenzeka, ukucoca ukungcola emoyeni, amanzi kunye nomhlaba.Kulo mongo, i-nanotechnology inikeza uluhlu olubanzi lwezakhono kunye nobuchwepheshe bokuphucula umgangatho wendawo ekhoyo.

I-Nanotechnology inika amandla okulawula umcimbi kwi-nanoscale kunye nokudala izinto ezinempahla ethile kunye nomsebenzi othile.Uphando oluvela kwi-European Union ekhethiweyo (i-EU) amajelo abonisa ithemba eliphezulu ngokumalunga namathuba / umngcipheko ohambelana ne-nanotechnology, apho uninzi lwazo luxhomekeke kwithemba lokuphucula umgangatho wobomi kunye nempilo.
