Izindaba - Ukufunda i-Air Quality Index

I-Air Quality Index (AQI) imelela amazinga okungcoliswa komoya.Inikeza izinombolo esikalini esiphakathi kuka-0 no-500 futhi isetshenziselwa ukusiza ukunquma ukuthi ikhwalithi yomoya kulindeleke ukuthi ingabi nempilo nini.

Ngokusekelwe kumazinga ekhwalithi yomoya yombuso, i-AQI ihlanganisa izinyathelo zokungcolisa umoya okukhulu eziyisithupha: i-ozone, i-carbon monoxide, i-nitrogen dioxide, i-sulphur dioxide, nosayizi ababili bezinhlayiya.Endaweni ye-Bay, izinto ezingcolisayo okungenzeka kakhulu zibangele I-Spare the Air Alert i-ozone, phakathi kuka-April no-Okthoba, kanye ne-particle, phakathi kukaNovemba noFebruwari.

Inombolo ngayinye ye-AQI ibhekisela enanini elithile lokungcola emoyeni.Kuningi lokungcola okuyisithupha okumelelwe ishadi le-AQI, izinga lenhlangano lihambisana nenani elingu-100. Uma ukugxiliswa kokungcolisa umoya kukhuphuka ngaphezu kuka-100, ikhwalithi yomoya ingaba yingozi emphakathini.

Izinombolo ezisetshenziselwa isikali se-AQI zihlukaniswe ngezigaba eziyisithupha ezinamakhodi anemibala:

0-50

Kuhle (G)

Imithelela yezempilo ayilindelekile uma ikhwalithi yomoya ikulolu hlu.

51-100

Okulingene (M)

Abantu abazwela ngokungavamile kufanele bacabangele ukukhawulela ukuzikhandla okude kwangaphandle.

101-150

Akunampilo kumaqembu azwelayo (USG)

Izingane ezikhuthele kanye nabantu abadala, kanye nabantu abanesifo sokuphefumula njengesifuba somoya, kufanele banciphise ukuzikhandla kwangaphandle.

151-200

Okungenampilo (U)

Izingane ezisebenzayo kanye nabantu abadala, kanye nabantu abanesifo sokuphefumula, njengesifuba somoya, kufanele bagweme ukuzikhandla kwangaphandle isikhathi eside;wonke umuntu, ikakhulukazi izingane, kufanele anciphise ukuzikhandla okude kwangaphandle.

201-300

Okungenampilo Kakhulu (VH)

Izingane ezisebenzayo kanye nabantu abadala, kanye nabantu abanesifo sokuphefumula, njengesifuba somoya, kufanele bagweme konke ukuzikhandla kwangaphandle;wonke umuntu, ikakhulukazi izingane, kufanele anciphise ukuzikhandla kwangaphandle.

301-500

Okuyingozi (H)

Izimo eziphuthumayo: wonke umuntu ugwema ukuzivocavoca kwangaphandle.

Ukufundwa okungaphansi kwe-100 ku-AQI akufanele kuthinte impilo yomphakathi jikelele, nakuba ukufundwa kwebanga eliphakathi kuka-50 kuya ku-100 kungase kuthinte abantu abazwela ngokungavamile.Amazinga angaphezu kuka-300 awavamile ukwenzeka e-United States.

Lapho i-Air District ilungiselela isibikezelo sezulu se-AQI sansuku zonke, sikala ukuhlangana okulindelekile kokungcoliswa kwemvelo ngakunye kweziyisithupha ezinkulu ezifakwe kunkomba, siguqule ukufundwa sibe izinombolo ze-AQI, futhi sibike inombolo ephezulu ye-AQI yendawo ngayinye yokubika.I-Spare the Air Alert ibizelwa Indawo yase-Bay lapho ikhwalithi yomoya kulindeleke ukuthi ingabi nempilo kunoma yiziphi izindawo ezinhlanu zokubika zesifunda.
