Comment cet AQI est-il calculé ?

The primary Air Quality Index (AQI) shown above is calculated using the US EPA Linear Interpolation formula based on PM2.5 concentration (Fine Particulate Matter).

Formule : Ip = [(Ihi - Ilow) / (Chi - Clow)] * (Cp - Clow) + Ilow

PM2.5 actuel : 124.589 µg/m³
Calcul : Votre ville se trouve dans la catégorie « Malsain » (Catégorie 4)."Malsain" (Catégorie 4).

Note: While several pollutants (O3, NO2, SO2) are monitored, PM2.5 is used as the primary "driver" for the main index value as it typically represents the highest health risk.

Questions Fréquemment Posées
