Muaj qhov sib txawv tseem ceeb ntawm AQI thiab API. Thawj qhov sib txawv yog nyob rau hauv lub npe, hloov ntawm 'Air Pollution Index' mus rau 'Air Quality Index'.
Thib ob, AQI kev faib tawm suav yog ua raws li kev hloov kho tshiab Ambient Air Quality Standard (GB3095-2012), uas ntsuas rau 6 cov pa phem: nplua cov teeb meem (PM2.5), inhalable particulate matter (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), zone (NO2) . Hauv qhov sib piv, API kev faib cov lej suav siv Ambient Air Quality Standard (GB3095-1996), ntsuas tsuas yog peb cov pa phem-SO2, NO2, thiab PM10-nrog kev hloov tshiab txhua hnub. Qhov tseem ceeb, PM2.5, thawj qhov ua rau haze, tsis suav nrog tus qauv no.

Raws li qhov tshwm sim, Air Quality Index (AQI) ntiav cov qauv nruj dua, saib xyuas cov pa phem ntau dua, thiab hloov kho ntau zaus, ua rau nws qhov kev ntsuam xyuas tau zoo dua los ntawm cov pej xeem cov kev paub dhau los.

Nws suav nrog xya qhov ntsuas tseem ceeb: 24-teev qhov nruab nrab ntawm sulfur dioxide (SO2), nitrogen dioxide (NO2), cov teeb meem me me (PM10 thiab PM2.5), thiab carbon monoxide (CO); Txhua hnub siab tshaj 1-teev nruab nrab thiab txhua hnub siab tshaj 8-teev txav nruab nrab ntawm ozone (O3).

Lub sijhawm tshaj tawm ntawm - lub sijhawm qhia lub voj voog yog teem rau ntawm 1 teev, nrog kev hloov tshiab rau txhua qhov kev soj ntsuam cov ntsiab lus tso tawm tam sim tom qab txhua teev, thiab ncua sijhawm yuav tsum tsis pub tshaj 1 teev. Qhov tseeb-lub sij hawm tshaj tawm suav nrog 9 qhov ntsuas: 1-teev qhov nruab nrab ntawm sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide, cov teeb meem me me (PM10), thiab cov teeb meem me me (PM2.5), nrog rau 8-teev qhov nruab nrab ntawm ozone thiab 24-teev txav nruab nrab ntawm PM5.10 thiab PM2.
