How to Read the Air Quality Index for Zizhuang

Good (0-50)

Air is fresh and healthy. Safe for all outdoor activities.

Moderate (51-100)

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+)

Serious health alert: everyone may experience serious life-threatening effects.

Good (0-12)

Fine particles are at minimal, safe levels. Air is optimal.

Moderate (12-35)

Acceptable air, but haze may be present in urban areas.

Sensitive (35-55)

Individuals with heart or lung disease should limit activity.

Unhealthy (55-150)

Particulate levels high enough to cause respiratory irritation.

Very Unhealthy (150-250)

Heavy haze. High risk to cardiovascular health for the public.

Hazardous (250+)

Lethal particulate concentrations. Critical neurological and lung risk.

Good (0-54)

Low levels of dust and coarse particles. Environment is safe.

Moderate (55-154)

Coarse particles may trigger coughing in sensitive groups.

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 Zizhuang?

Pollution in Zizhuang is primarily driven by 9.0 km/h N winds, local traffic emissions, and industrial activity, which influence the current PM2.5 concentration of 53.85 µg/m³.

Is the AQI in Zizhuang safe today?

Today's AQI is 146, which is categorized as Unhealthy (Sensitive). This means the air quality is unhealthy (sensitive) for the general population.
