How to Read the Air Quality Index for Sanniquellie

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.

Sensitive (155-254)

Visible dust pollution. Sensitive groups should avoid heavy labor.

Unhealthy (255-354)

Widespread respiratory impacts likely for the population.

Very Unhealthy (355-424)

Dangerous dust and debris levels. Significant warnings issued.

Hazardous (425+)

Extremely high concentrations. Stay inside with filtration.

Good (0-54)

Surface ozone levels are within a safe, natural range.

Moderate (55-70)

Acceptable air, but sensitive individuals may feel chest tightness.

Sensitive (71-85)

Rising ozone can trigger airway inflammation in active children.

Unhealthy (86-105)

Avoid heavy outdoor work during the hottest part of the day.

Very Unhealthy (106-200)

Serious lung function reduction likely across the public.

Hazardous (201+)

Emergency ozone levels. Risk of permanent lung tissue damage.

Good (0-53)

Nitrogen levels are optimal. Safe for everyone.

Moderate (54-100)

Typical background levels for high-density urban areas.

Sensitive (101-360)

Increased risk of respiratory infections for vulnerable groups.

Unhealthy (361-649)

Significant airway inflammation likely near traffic zones.

Very Unhealthy (650-1249)

Acute respiratory distress potential. High-risk groups stay indoors.

Hazardous (1250+)

Toxic concentrations. Immediate health precautions required.

Good (0-4.4)

Carbon Monoxide levels are clean and non-toxic.

Moderate (4.5-9.4)

Acceptable; may affect those with specific heart conditions.

Sensitive (9.5-12.4)

Reduced oxygen delivery to the heart may occur.

Unhealthy (12.5-15.4)

Headaches and fatigue may occur in urban canyons.

Very Unhealthy (15.5-30.4)

Significant cardiovascular distress. Mental confusion possible.

Hazardous (30.5+)

Lethal potential. Immediate risk of neurological collapse.

Good (0-35)

Optimal air quality with no sulfur detection.

Moderate (36-75)

Acceptable air; minor odors possible near industry.

Sensitive (76-185)

Bronchoconstriction possible for active asthmatics.

Unhealthy (186-304)

Respiratory distress likely for the wider population.

Very Unhealthy (305-604)

Significant wheezing and shortness of breath likely.

Hazardous (605+)

Extreme respiratory danger. Significant life risk.

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 Sanniquellie?

Pollution in Sanniquellie is primarily driven by 4.3 km/h WSW winds, local traffic emissions, and industrial activity, which influence the current PM2.5 concentration of 43.15 µg/m³.

Is the AQI in Sanniquellie safe today?

Today's AQI is 120, which is categorized as Unhealthy (Sensitive). This means the air quality is unhealthy (sensitive) for the general population.
