"Ndife otetezeka kupuma m'nyumba, chifukwa nyumbayi imatiteteza ku zotsatira zofalitsidwa kwambiri za kuipitsidwa kwa mpweya." Izi sizowona, makamaka mukakhala mukugwira ntchito, mukukhala kapena kuphunzira m'matauni komanso ngakhale mutakhala kumidzi.
Lipoti la kuipitsidwa kwa mpweya wa m’nyumba m’masukulu a ku London, lofalitsidwa ndi UCL Institute for Environmental Design and Engineering, linasonyeza mosiyana kuti “ana omwe amakhala – kapena opita kusukulu – pafupi ndi misewu yodutsa anthu ambiri amakhudzidwa kwambiri ndi kuwonongeka kwa magalimoto, ndipo anali ndi vuto lalikulu la mphumu yaubwana ndi kupuma." Kuphatikiza apo, We Design For (mlangizi wotsogola wa IAQ ku UK) adapezanso kuti "mpweya wamkati m'nyumba zoyesedwa ndi mlangizi unali woipa kuposa mpweya wakunja." Mtsogoleri wawo a Pete Carvell adawonjezeranso kuti "Zinthu m'nyumba nthawi zambiri zimakhala zoipitsitsa. Anthu okhala m'matauni ayenera kufunsa mafunso ochulukirapo okhudzana ndi mpweya wawo wamkati. Tiyenera kuyang'ana zomwe tingachite kuti mpweya wamkati ukhale wabwino, monga momwe timagwirira ntchito kuchepetsa kuipitsidwa kwa mpweya wakunja. ”
M'maderawa, kuwonongeka kwakukulu kwa mpweya wamkati kumachitika chifukwa cha kuipitsidwa kwa kunja, monga NO2 (magwero akunja amawerengera 84%), zoipitsa zokhudzana ndi magalimoto ndi tinthu tating'onoting'ono (kupitilira malire owongolera PM mpaka 520%), zomwe zimapangitsa kuti azikhala ndi chiopsezo chachikulu cha mphumu, zizindikiro za mphumu ndi matenda ena opuma. Kuphatikiza apo, CO2, VOCs, tizilombo tating'onoting'ono ndi zowotcha zimatha kukhazikika m'derali ndikumangirira pamalo, popanda mpweya wabwino.
Ndi masitepe ati omwe angatengedwe?
1. Kuwongolera gwero la zoipitsa.
a) Zowononga panja. Kutsatira malamulo okhwima owongolera mapulani a mizinda ndikuwongolera kuchuluka kwa magalimoto pamsewu, kuwonetsetsa kuti mzindawu ndi wobiriwira komanso waukhondo. Ndikukhulupirira kuti ambiri mwa mizinda yotukuka anali atayika kale manja awo pa iwo ndikuwongolera tsiku ndi tsiku, koma zimafunika nthawi yayitali.
b) Zowononga m'nyumba, monga ma VOC ndi zoletsa. Izi zitha kupangidwa kuchokera kuzinthu zamkati, monga makapeti, mipando yatsopano, utoto komanso zoseweretsa m'chipindamo. Conco, tiyenela kusankha mosamala zinthu zimene timagwilitsila nchito m’nyumba ndi m’maofesi athu.
2. Kugwiritsa ntchito njira zopangira mpweya wabwino wamakina.
Mpweya wabwino ndi wofunikira kwambiri poletsa zowononga popereka mpweya wabwino, komanso kuchotsa zowononga m'nyumba.
a) Pogwiritsa ntchito zosefera zapamwamba, tikhoza kusefa 95-99% ya PM10 ndi PM2.5, komanso kuchotsa nitrogen dioxide, kuonetsetsa kuti mpweya uli woyera komanso wotetezeka kupuma.
b) Posintha mpweya wamkati wamkati ndi mpweya wabwino waukhondo, zowononga zamkati zimachotsedwa pang'onopang'ono, kuwonetsetsa kuti ndizochepa, zopanda mphamvu kapena zopanda mphamvu kwa thupi la munthu.
c) Ndi mpweya wabwino wamakina, titha kupanga chotchinga chakuthupi ndi kusiyana kwapakatikati - kupanikizika pang'ono kwamkati mkati, kotero kuti mpweya ukutuluka m'derali, motero kuti zowononga zakunja zisalowe.
Ndondomeko sizinthu zomwe tingasankhe; chifukwa chake tiyenera kuyang'ana kwambiri posankha zida zobiriwira komanso chofunikira kwambiri kuti tipeze njira yabwino yolowera mpweya pamalo anu!
