Kumasulidwa nthawi:2026-03-02
Penti yokhala ndi zigawo ziwiri imagwiritsidwa ntchito kwambiri m'misewu yayikulu, misewu yamizinda, ndi malo oimikapo magalimoto chifukwa ndi yolimba komanso yomatira kwambiri. Mosiyana ndi utoto wapaketi wapaketi imodzi, imakhala ndi zigawo ziwiri zosiyana zomwe zimachita pambuyo posakanikirana. Izi zimakhala zolimba, zokhala nthawi yayitali zomwe zimatha kupirira kuchuluka kwa magalimoto pamsewu komanso nyengo yovuta.
Chimodzi mwazabwino za chilengedwe cha machitidwe a magawo awiri ndi moyo wawo wautali wautumiki. Chifukwa zolemberazi sizitenga nthawi yayitali, misewu imafunikira kupentanso pafupipafupi. Izi zimachepetsa kugwiritsiridwa ntchito kwazinthu zonse, kulongedza, ndi mphamvu zoyendera pakapita nthawi. M'matauni otanganidwa monga New York City ndi London, komwe kuchuluka kwa magalimoto kumakwera, zizindikiro zokhalitsa zimatha kuchepetsa kwambiri mpweya wokhudzana ndi kukonza.
Komabe, nkhawa za chilengedwe zidakalipo. Pakupanga ndi kugwiritsa ntchito, ma formulations ena amatha kutulutsa ma volatile organic compounds (VOCs), omwe amathandizira kuwononga mpweya komanso kupanga utsi. Malamulo okhazikitsidwa ndi mabungwe ngati United States Environmental Protection Agency akakamiza opanga kupanga njira zina zotsika kwambiri za VOC kapena zopanda zosungunulira. Mitundu yambiri yamakono yamagulu awiri tsopano imagwiritsa ntchito madzi kapena olimba kwambiri kuti achepetse mpweya.
Nkhani ina imakhudza tinthu tating'onoting'ono tating'onoting'ono tomwe timapangidwa ndi kuwonongeka. Pamene zizindikiro zapamsewu zimachepa pang'onopang'ono chifukwa cha kuchuluka kwa magalimoto, tinthu tating'onoting'ono tingalowe m'nthaka ndi m'madzi. Ofufuza ndi mabungwe azachilengedwe akuphunzira ma resin okhazikika komanso zodzaza kuti achepetse izi.
Ponseponse, utoto wamitundu iwiri umapereka zabwino zonse zachilengedwe komanso zovuta. Ikapangidwa ndi mpweya wochepa komanso kukhazikika kwakukulu m'maganizo, imatha kuchepetsa kugwiritsa ntchito zinthu kwanthawi yayitali ndikusunga chitetezo chamsewu. Kupititsa patsogolo kwatsopano ndi miyezo yokhwima kudzakhala chinsinsi chogwirizanitsa ntchito ndi udindo wa chilengedwe.
