Iindaba-Ukufunda iSalathisi soMgangatho woMoya

Isalathiso soMgangatho woMoya (AQI) luphawu lwamanqanaba oxinzelelo longcoliseko lomoya. Inika amanani kwisikali phakathi kwe-0 kunye ne-500 kwaye isetyenziselwa ukunceda ukufumanisa xa kulindeleke ukuba umgangatho womoya ungabikho mpilweni.

Ngokusekwe kwimigangatho yomgangatho womoya womanyano, i-AQI ibandakanya imilinganiselo yezingcolisi zomoya ezithandathu: i-ozone, i-carbon monoxide, i-nitrogen dioxide, i-sulphur dioxide, kunye neesayizi ezimbini ze-particle. KuMmandla weBay, ezona zinto zingcolisayo ezinokukhokelela kwi-Spare the Air Alert yi-ozone, phakathi kuka-Epreli no-Oktobha, kunye ne-particle, phakathi kukaNovemba noFebruwari.

Inombolo nganye ye-AQI ibhekiselele kwizixa ezithile zongcoliseko lomoya. Ubuninzi bezinto ezingcolileyo ezithandathu ezimele itshathi ye-AQI, umgangatho we-federal uhambelana nenani le-100. Ukuba ukuxinwa kokungcola kuphakama ngaphezu kwe-100, umgangatho womoya unokuba yingozi kuluntu.

Amanani asetyenziswa kwisikali se-AQI ahlulwe abe ziindidi ezinemibala emithandathu:

0-50

Kulungile (G)

Iimpembelelo zempilo azilindelekanga xa umgangatho womoya ukuloluhlu.

51-100

Phakathi (M)

Abantu abanovelwano ngokungaqhelekanga kufuneka bacinge ngokunciphisa umthambo wangaphandle ixesha elide.

101-150

Ayilunganga kumaqela abuthathaka (USG)

Abantwana abasebenzayo kunye nabantu abadala, kunye nabantu abanesifo sokuphefumla esifana ne-asthma, kufuneka banciphise umgudu wangaphandle.

151-200

Akusempilweni (U)

Abantwana abakhutheleyo kunye nabantu abadala, kunye nabantu abanesifo sokuphefumula, njenge-asthma, kufuneka bagweme ukunyamezela kwangaphandle ixesha elide; wonke umntu, ngakumbi abantwana, kufuneka banciphise umgudu wokuzibhokoxa wangaphandle ixesha elide.

201-300

Ayinampilo kakhulu (VH)

Abantwana abakhutheleyo kunye nabantu abadala, kunye nabantu abanesifo sokuphefumula, njenge-asthma, kufuneka baphephe yonke imisebenzi yangaphandle; wonke umntu, ngakumbi abantwana, kufuneka banciphise umgudu wangaphandle.

301-500

Inobungozi (H)

Iimeko ezingxamisekileyo: wonke umntu uyakuphepha ukwenza umthambo wangaphandle.

Ukufundwa okungaphantsi kwe-100 kwi-AQI akufanele kuchaphazele impilo yoluntu ngokubanzi, nangona ukufundwa kwinqanaba eliphakathi kwe-50 ukuya kwi-100 kunokuchaphazela abantu abanovelwano ngokungaqhelekanga. Amanqanaba angaphezu kwama-300 awafane enzeki eMelika.

Xa iSithili soMoya silungiselela uqikelelo lwemihla ngemihla lwe-AQI, lulinganisa ugxininiso olulindelekileyo lwento nganye kwezintandathu ezingcolisayo ezibandakanyiweyo kwisalathiso, siguqula ukufundwa sibe ngamanani e-AQI, kwaye sixela eyona nombolo iphezulu ye-AQI kwindawo nganye yokunika ingxelo. I-Spare the Air Alert ibizwa kwi-Bay Area xa umgangatho womoya ulindeleke ukuba ungabikho sempilweni kuyo nayiphi na imimandla emihlanu yokunika ingxelo.
