Igipimo cy'Ubuziranenge bw'Umucyo (AQI) ni ikimenyetso cy'ingano y'ubuhumekero bw'umwuka. Gitanga imibare ku gipimo kiri hagati ya 0 na 500 kandi gikoreshwa mu gufasha kumenya igihe ubwiza bw'umwuka bwitezweho kuba bubi.
Hashingiwe ku mahame y’ubuziranenge bw’ikirere cya leta, AQI ikubiyemo ibipimo bitandatu by’ingenzi byangiza ikirere: ozone, monoxide ya karubone, gazi ya azote, gazi ya sulfur, n’ibice bibiri by’ibintu binini. Mu gace ka Bay, ibintu bihumanya ikirere bishobora gutera itangazwa ry’ikirere ni ozone, hagati ya Mata na Ukwakira, n’ibice, hagati y’Ugushyingo na Gashyantare.
Buri nomero ya AQI yerekeza ku ngano yihariye y'imyanda iri mu kirere. Ku bipimo bitandatu by'imyanda bigaragazwa n'imbonerahamwe ya AQI, igipimo ngenderwaho cya leta gihuye n'umubare wa 100. Iyo ubwinshi bw'imyanda irenga 100, ubwiza bw'umwuka bushobora kuba bubi ku baturage.

Ibipimo biri munsi ya 100 kuri AQI ntibigomba kugira ingaruka ku buzima bw'abaturage muri rusange, nubwo ibipimo biri hagati ya 50 na 100 bishobora kugira ingaruka ku bantu bafite ubumuga budasanzwe. Ibipimo biri hejuru ya 300 ntibikunze kubaho muri Leta Zunze Ubumwe za Amerika.
Iyo Akarere k’Indege gategura iteganyagihe rya buri munsi rya AQI, gapima ingano y’ibintu bitandatu by’ingenzi byanduye biri mu rutonde, gahindura ibipimo mu mibare ya AQI, kandi kagatanga umubare munini wa AQI kuri buri gace gatanga raporo. Itangazo ryo kwirinda ikirere risabwa ku gace k’inyanja iyo ubwiza bw’umwuka butegerejwe kuba bubi muri ako gace kose mu duce dutanu dutanga raporo muri ako karere.
