Kuwerenga Chiyerekezo cha Ubwino wa Mpweya

Chizindikiro cha Ubwino wa Mpweya (AQI) ndi chizindikiro cha kuchuluka kwa kuipitsidwa kwa mpweya. Chimaika manambala pa sikelo pakati pa 0 ndi 500 ndipo chimagwiritsidwa ntchito pothandiza kudziwa nthawi yomwe mpweya ukuyembekezeka kukhala wopanda thanzi.

Kutengera miyezo ya mpweya wabwino wa boma, AQI imaphatikizapo njira zisanu ndi chimodzi zoyezera kuipitsa mpweya: ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, ndi tinthu tating'ono ...

Nambala iliyonse ya AQI imatanthauza kuchuluka kwa kuipitsidwa kwa mpweya mumlengalenga. Pa zoipitsa zambiri zisanu ndi chimodzi zomwe zikuyimiridwa ndi tchati cha AQI, muyezo wa boma umagwirizana ndi chiwerengero cha 100. Ngati kuchuluka kwa choipitsa kukwera kuposa 100, mpweya wabwino ungakhale woipa kwa anthu onse.

Kuwerenga pansi pa 100 pa AQI sikuyenera kukhudza thanzi la anthu onse, ngakhale kuti kuwerenga pakati pa 50 ndi 100 kungakhudze anthu omwe ali ndi vuto lachilendo. Kuchuluka kwa anthu omwe ali ndi vuto la mtima pamwamba pa 300 sikumachitika kawirikawiri ku United States.

Pamene Air District ikukonzekera kulosera kwa tsiku ndi tsiku kwa AQI, imayesa kuchuluka komwe kumayembekezeredwa kwa chilichonse mwa zinthu zisanu ndi chimodzi zazikulu zodetsa zomwe zili mu index, kusintha mawerengedwewo kukhala manambala a AQI, ndikupereka nambala ya AQI yapamwamba kwambiri pa gawo lililonse la malipoti. Chidziwitso cha Kusunga Mlengalenga chimafunidwa ku Bay Area pamene mpweya wabwino ukuyembekezeka kukhala wosatetezeka m'malo aliwonse asanu a lipoti m'chigawochi.
