Kuwonongeka kwa ndege ku China kukakamiza ma eyapoti ndi misewu ikuluikulu kuti itseke

Kuwononga mpweya ku China

China imagwiritsa ntchito malasha ngati mafuta m'mafakitale ake ambiri. Ndilo lotsogola kwambiri padziko lonse lapansi la malasha. Chifukwa cha izi, magwiridwe ake azachuma komanso chitukuko chake m'misika ndichopatsa chidwi. Mpikisano waku China ndikuti zitha kunenedwa kuti chuma choyamba padziko lonse lapansi.

Komabe, sizinthu zonse ndi chitukuko komanso chiyembekezo. Kugwiritsa ntchito malasha mobwerezabwereza kuwonongeka kwa mlengalenga ku China ndipamwamba kwambiri. Imafika pamilingo yoposa lamulo loti nzika ziyenera kuvala maski kuti zizitha kutuluka osapuma mpweya wowopsa. Sabata ino kuipitsidwa kwakhala kwakukulu kotero kuti awona anakakamizidwa kutseka eyapoti ya Tianjin ndi misewu yayikulu kwa maola ochepa a mzindawu kuti tipewe ngozi zomwe zingachitike.

Chifukwa chiyani kuipitsa kotere?

Kuwonongeka kwa mpweya kumakhudza mizinda kutengera kusintha kwa nyengo monga kuchuluka kwa dzuwa lomwe limagunda pamwamba, kayendetsedwe ka mphepo, mvula, ndi zina zambiri. Nthawi zambiri, dziko lapansi limakhala lotentha kuposa mpweya womwe umazungulira pamwamba pake. Ichi ndichifukwa chake mpweya wotentha, pochepera, umayamba kukwera. Masiku amene kutentha kumakhala kokwezeka pamwamba komanso kutsika kwambiri, mpweya woipitsa umakwera ndipo sunakodwe mumzindawu, ndi choncho china chosawopsa ku thanzi.

Vuto lina lomwe timadzipeza m'mizinda ndi masiku amphepo. Akaphulitsa mphepo yamkuntho yothandiza kufalitsa kuipitsa, China itha kupuma mpweya wowononga kwambiri. Ndiye chachitika ndi chiyani kumapeto kwa sabata lino kuti kuipitsa madzi kukhale kwakukulu? Chabwino, pakakhala masiku amvula, masiku omwe dzuwa silinakhudze kwambiri padziko lapansi kapena masiku omwe kusiyanasiyana kwa kutentha masana kumakhala kovuta, chodabwitsa chimatchedwa kutembenukira kwa matenthedwe. Ndiye kuti, mpweya wotentha wochokera pamwamba wakwera mwachangu kwambiri kapena sikuti umangoyandikira padziko lapansi motero mpweya umazizira. Masiku amenewo pomwe mpweya wozizira umalamulira pamwamba pamizinda, pokhala wokulirapo, sikumadzuka ndikupanga gawo la kukhazikika kwa mlengalenga momwe zoipitsa zimakhazikika. Pazifukwa izi, kuipitsa dziko ku China ndikokwera chifukwa ngakhale chifukwa chamvula kapena zowononga mphepo zabalalika. 

Kuwonongeka kwakukulu

Njira zotsutsana ndi kuipitsa

Beijing, Tianjin ndi mizinda ina makumi awiri ili mkati Chenjezo lofiira (chenjezo lapamwamba kwambiri la kuwonongeka kwa nthaka) chifukwa cha kuchuluka kwa zinthu zomwe zimawononga chilengedwe zomwe nzika zitha kupumira. Zikuyembekezeka kuti mpaka Lachitatu kuipitsa sikumachepa, chifukwa chake adatsekedwa mafakitale, ntchito, zoletsa pamsewu masauzande ambiri akhazikitsidwa ndipo maphunziro ayimitsidwa m'masukulu oyambira.

Pakadali pano, Tianjin ndiye mzinda womwe wakhudzidwa kwambiri ndi utsi. Utsiwu womwe umayambitsidwa ndi kuipitsa umachepetsa kuwonekera kwakuti ma eyapoti adakakamizidwa kutseka. Nthawi yomwe ndege idatsekedwa adachotsedwa pafupifupi ndege 131.

Malire oyipitsa malinga ndi WHO

World Health Organisation (WHO) sikulangiza kuti munthu azikhala kwa maola opitilira 24 akuwonongeka ma micrograms opitilira 25 pa kiyubiki mita wa tinthu tina toipitsa tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono kuposa 2,5 micrograms pa kiyubiki mita yamagawo oipitsa a XNUMX mamilimita (otchedwa PM2,5) popeza amakhala ndi gawo laling'ono chonchi amatha kufikira pulmonary alveoli ndikupanga mavuto am'mapapo ndi amtima.

Komabe, kumapeto kwa sabata lino malire omwe amaloledwa ndi WHO apitilira, kupitirira 1.000 tinthu tating'ono pa kiyubiki mita. Izi zadetsa kwambiri kotero kuti amalimbikitsa kuti asatuluke m'nyumba ndi kutseka zitseko zonse ndi mawindo.

Tiyerekeze kuti mukukhala mumzinda umene mukuwononga kwambiri moti simungathe n’komwe kuchoka panyumba panu. Ichi ndichifukwa chake zowononga mumlengalenga zomwe zimawononga anthu komanso dziko lapansi ziyenera kuchepetsedwa.

    Malinga ndi nkhani yake, sizikudziwika kuti kuchuluka kwa ma micrograms 25 pa kiyubiki mita kupitilira pati. Iyenera kukhala yochuluka ndipo ndikuganiza kuti ndi yochulukirapo kuposa ma 1000 tinthu tating'onoting'ono pamiyubiki mita. Ichi ndi chinthu china kuposa ma micrograms! Koma sanena kuti ndi zochuluka bwanji zomwe zidapitilira malire a ma micrograms 25 pa kiyubiki mita ...? Ndikuganiza kuti akhala ma micrograms 1000 pa kiyubiki mita osati ma 1000 tinthu tating'ono!
