"Siphephe ngempela ukuphefumula endlini, ngoba lesi sakhiwo siyasivikela emiphumeleni esakazwa kabanzi yokungcoliswa komoya." Hhayi-ke, lokhu akulona iqiniso, ikakhulukazi uma usebenza, uhlala noma ufunda ezindaweni zasemadolobheni ngisho nalapho uhlala endaweni engaphansi kwedolobha.
Umbiko wokunukubezeka komoya ongaphakathi ezikoleni zaseLondon, oshicilelwe yi-UCL Institute for Environmental Design and Engineering, ubonise ngenye indlela ukuthi “izingane ezihlala - noma ezifundayo - eduze nemigwaqo ephithizelayo zichayeke emazingeni aphezulu okungcoliswa kwezimoto, futhi zinezinga eliphezulu isifuba somoya ebuntwaneni kanye ne-whee.” Ukwengeza, i-We Design For (i-IAQ consultancy ehamba phambili e-UK) iphinde yathola ukuthi "ikhwalithi yomoya wasendlini ezakhiweni ezihlolwe yi-consultant yayimbi kunekhwalithi yomoya wangaphandle." Umqondisi wayo uPete Carvell wengeze ngokuthi “Izimo zasendlini zivame ukuba zimbi kakhulu. Abantu abahlala emadolobheni badinga ukubuza imibuzo eminingi mayelana nekhwalithi yomoya wabo wasendlini. Kudingeka sibheke ukuthi yini esingayenza ukuze senze izinga lomoya wasendlini libe ngcono, njengoba nje sisebenzela ukunciphisa ukungcoliswa komoya wangaphandle.”
Kulezi zindawo, ukungcoliswa komoya okuningi kwangaphakathi kubangelwa ukungcola kwangaphandle, njengo-NO2 (imithombo engaphandle ibalwe ku-84%), ukungcola okuhlobene nethrafikhi nezinhlayiya ezincane (eqa imikhawulo yesiqondiso se-PM ngokufika kokungu-520%), okuholela ekubeni nengcuphe ephezulu yokuhlaselwa yisifuba somoya, izimpawu zesifuba somoya kanye nezinye izifo zokuphefumula. Ngaphezu kwalokho, i-CO2, i-VOCs, amagciwane kanye nezinto ezingezwani nomzimba zingakheka endaweni futhi zinamathele ezindaweni ezingaphezulu, ngaphandle kokungena komoya ngendlela efanele.
Yiziphi izinyathelo ezingathathwa?
1. Ukuphatha umthombo we ukungcola.
a) Ukungcola kwangaphandle. Ukusebenzisa inqubomgomo eqinile yokuqondisa ukuhlelwa kwedolobha kanye nokulawula ukuhamba kwezimoto ngendlela efanele, ukuqinisekisa ukuthi idolobha liluhlaza futhi lihlanzekile. Ngikholwa ukuthi iningi lamadolobha athuthukile abesevele ebeke izandla phezu kwawo futhi ewathuthukisa usuku nosuku, kodwa kudinga isikhathi eside.
b) Ukungcola kwasendlini, njengama-VOC kanye nezinto ezingezwani nazo. Lokhu kungenziwa ngezinto ezingaphakathi endlini, njengokhaphethi, ifenisha entsha, upende ngisho namathoyizi ekamelweni. Ngakho, kufanele sikhethe ngokucophelela lokho esikusebenzisa emakhaya nasemahhovisi ethu.
2. Ukusetshenziswa kwezixazululo ezifanele zokungenisa umoya ngomshini.
Ukungena komoya kubaluleke kakhulu ukuze kulawulwe ukungcola emoyeni ohlanzekile, kanye nokususa ukungcola kwasendlini.
a) Ngokusetshenziswa kwezihlungi ezisebenza kahle kakhulu, singakwazi ukuhlunga u-95-99% we-PM10 ne-PM2.5, futhi sisuse i-nitrogen dioxide, siqinisekise ukuthi umoya uhlanzekile futhi uphephile ukuphefumula.
b) Lapho ufaka esikhundleni somoya odala wasendlini ngomoya ohlanzekile ohlanzekile, ukungcola kwangaphakathi kuzosuswa kancane kancane, kuqinisekiswe ukuthi akugxili kakhulu, kunomphumela omncane noma ongenawo umthelela emzimbeni womuntu.
c) Ngokungenisa umoya ngomshini, singakha umgoqo ongokomzimba ngokuhluka kwengcindezi - ingcindezi encane engaphakathi endlini, ukuze umoya uzobe uphuma endaweni, ngaleyo ndlela sivimbele ukungcola kwangaphandle ukuthi kungangeni.
Izinqubomgomo akuyona into esingayinquma; ngakho-ke kufanele sigxile kakhulu ekukhetheni izinto eziluhlaza futhi okubaluleke kakhulu ukuthola isisombululo esifanele sokungenisa umoya endaweni yakho!
