Acceptable air quality, though sensitive groups should monitor comfort.

Unhealthy (Sensitive) (101-150)

Vulnerable groups (children, elderly) should limit outdoor exertion.

Unhealthy (151-200)

Everyone begins to experience health effects. Stay indoors where possible.

Very Unhealthy (201-300)

Significant health impact for entire population. Emergency conditions.

Hazardous (301+)

How is this AQI calculated?

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).

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

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.

Frequently Asked Questions

What is the main cause of air pollution in Iriba?

Pollution in Iriba is primarily driven by 9.0 km/h ENE winds, local traffic emissions, and industrial activity, which influence the current PM2.5 concentration of 55.5 ยตg/mยณ.

Is the AQI in Iriba safe today?

Today's AQI is 151, which is categorized as Unhealthy (Sensitive). This means the air quality is unhealthy (sensitive) for the general population.
