Nkhani ya kuipitsa chilengedwe yakhala nkhani yaikulu m’dziko lamakonoli.Kuipitsa chilengedwe, makamaka chifukwa cha mankhwala oopsa, kumaphatikizapo kuwononga mpweya, madzi, ndi nthaka.Kuipitsa kumeneku sikumangowononga zamoyo zosiyanasiyana, komanso kuwononga thanzi la anthu.Kuipitsidwa komwe kukuchulukirachulukira tsiku ndi tsiku kumafunikira chitukuko chabwinoko kapena kutulukira kwaukadaulo nthawi yomweyo.Nanotechnology imapereka maubwino ambiri opititsa patsogolo umisiri wachilengedwe komanso kupanga ukadaulo watsopano womwe uli wabwinoko kuposa umisiri wamakono.M'lingaliro limeneli, nanotechnology ili ndi mphamvu zazikulu zitatu zomwe zingagwiritsidwe ntchito m'madera a chilengedwe, kuphatikizapo kuyeretsa (kukonzanso) ndi kuyeretsa, kuzindikira zowonongeka (kuzindikira ndi kuzindikira), komanso kupewa kuwononga chilengedwe.

M'dziko lamakono lomwe mafakitale akhala amakono komanso otsogola, malo athu ali odzaza ndi mitundu yosiyanasiyana ya zoipitsa zomwe zimachokera ku zochita za anthu kapena njira zamafakitale.Zitsanzo za zinthu zoipitsa zimenezi ndi carbon monoxide (CO), chlorofluorocarbons (CFCs), heavy metal (arsenic, chromium, lead, cadmium, mercury ndi zinki), ma hydrocarbon, nitrogen oxides, organic compounds (volatile organic compounds and dioxins), sulfure dioxide ndi particles.Zochita za anthu, monga mafuta, malasha ndi gasi, zimakhala ndi kuthekera kwakukulu kosintha utsi wochokera kuzinthu zachilengedwe.Kuphatikiza pa kuipitsidwa kwa mpweya, palinso kuipitsidwa kwa madzi chifukwa cha zinthu zosiyanasiyana, kuphatikizapo kutaya zinyalala, kutayira kwa mafuta, kutayikira kwa feteleza, mankhwala ophera udzu ndi mankhwala ophera tizilombo, zotuluka m’mafakitale ndi kuyaka ndi kutulutsa mafuta oyaka.

Zowononga nthawi zambiri zimapezeka zitasakanizidwa mumlengalenga, madzi ndi nthaka.Choncho, timafunikira teknoloji yomwe imatha kuyang'anira, kuzindikira, ndipo, ngati n'kotheka, kuyeretsa zowonongeka kuchokera ku mpweya, madzi ndi nthaka.Munkhaniyi, nanotechnology imapereka kuthekera kosiyanasiyana ndi matekinoloje kuti apititse patsogolo malo omwe alipo.

Nanotechnology imapereka mphamvu yowongolera zinthu pa nanoscale ndikupanga zida zomwe zili ndi zinthu zina zomwe zimakhala ndi ntchito inayake.Kafukufuku wochokera ku zofalitsa zosankhidwa za European Union (EU) akuwonetsa kuti ali ndi chiyembekezo chochuluka ponena za mwayi / chiwopsezo chokhudzana ndi nanotechnology, kumene ambiri a iwo amati ndi chiyembekezo cha kusintha kwa moyo ndi thanzi.
