Iyo Air Quality Index (AQI) inomiririra yemazinga ekusvibiswa kwemhepo. Inopa nhamba pachiyero pakati pe0 ne500 uye inoshandiswa kubatsira kuziva kana hutano hwemhepo hunotarisirwa kuve husina kunaka.
Zvichienderana nemubatanidzwa wemhando yemhando yemhepo, iyo AQI inosanganisira zviyero zvezvitanhatu zvikuru zvinosvibisa mweya: ozone, kabhoni monoxide, nitrogen dioxide, sulfur dioxide, uye saizi mbiri dzezvinhu. MuBay Area, zvinosvibisa zvinonyanya kukonzeresa Spare the Air Alert ozone, pakati paApril naGumiguru, uye zvinhu, pakati paNovember naFebruary.
Imwe neimwe nhamba yeAQI inoreva huwandu hwakati hwekusvibiswa mumhepo. Kune dzakawanda zvezvitanhatu zvakasvibiswa zvinomiririrwa neAQI chati, chiyero chehurumende chinopindirana nehuwandu hwezana 100. Kana huwandu hwekusvibiswa hukakwira kupfuura 100, hutano hwemhepo hunogona kuva husina kunaka kuvanhu.

Kuverenga kuri pasi pezana paAQI hakufanire kukanganisa hutano hweveruzhinji, kunyangwe kuverenga kuri pakati nepakati kubva pamakumi mashanu kusvika kugumi kunogona kukanganisa vanhu vasinganzwisisike. Mazinga ari pamusoro pe300 haawanzo kuitika muUnited States.
Kana Dunhu reMhepo richigadzira fungidziro yemazuva ese yeAQI, inoyera kusungwa kunotarisirwa kune imwe neimwe yezvinosvibisa zvitanhatu zvakasanganiswa muindekisi, inoshandura kuverenga kuita manhamba eAQI, uye inoshuma nhamba yepamusoro yeAQI yenzvimbo yega yega yekuzivisa. A Spare the Air Alert inodaidzwa kuBay Area apo mhando yemhepo inotarisirwa kuve isina hutano mune chero yenzvimbo shanu dzekushuma.
