Mayelana nalolu hlelo lokusebenza
Imephu ikhombisa imininingwane ye-AQI yamazwe amaningi aseNyakatho naseNingizimu Melika, eYurophu, e-Asia nase-Australia.
Inkomba yekhwalithi yomoya isuselwa ekulinganisweni kwe:
- i-ozone esezingeni lomhlaba
- ukungcoliswa kwezinhlayiyana (okwaziwa nangokuthi i-particulate matter, kufaka phakathi i-PM2.5 ne-PM10)
- isikhutha
- isibabule dioxide
- i-nitrogen dioxide
Iziteshi eziningi emephini ziqapha imininingwane ye-PM2.5 ne-PM10, kepha kukhona okumbalwa okuhlukile lapho kutholakala kuphela i-PM10.
I-AQI ihlukaniswe izigaba eziyisithupha. Isigaba ngasinye sihambisana nezinga elihlukile lokukhathazeka kwezempilo. Isigaba ngasinye sinombala othile. Umbala wenza kube lula kubantu ukuthi banqume ngokushesha ukuthi ikhwalithi yomoya ifinyelela emazingeni angenampilo. Ukuphakama kwenani le-AQI, kukhuphuka izinga lokungcola komoya futhi kukhula nokukhathazeka kwezempilo.
Imininingwane ihlinzekwe yi-World Air Quality Index Project (waqi.info ne-aqicn.org)

Ukuphepha kuqala ngokuqonda ukuthi onjiniyela baqoqa futhi babelane kanjani ngedatha yakho. Ubumfihlo bedatha nezinqubo zokuphepha zingahluka kuye ngokusebenzisa kwakho, isifunda, nobudala. Unjiniyela unikeze lolu lwazi futhi angalubuyekeza ngokuhamba kwesikhathi.
Le app ingabelana ngalezi zinhlobo zedatha nezinkampani ezingahlobene ngqo
Indawo, Umsebenzi wohlelo lokusebenza nabanye abangu-2
Ayikho idatha eqoqiwe
Funda kabanzi mayelana nokuthi onjiniyela bakuveza kanjani ukuqoqwa
Idatha ayibetheliwe
Idatha ayikwazi ukusulwa
Yini entsha
