🇲🇲 Luftkvalitetsindeks (AQI) i Sittwe, Myanmar
Helseanbefalinger for innbyggere i Sittwe
Luftkvaliteten er akseptabel. For noen forurensninger kan det imidlertid være en moderat helserisiko for et svært lite antall mennesker. Følsomme grupper bør vurdere å redusere langvarig utendørs anstrengelse.

Nåværende vær i Sittwe
Slik leser du luftkvalitetsindeksen for Sittwe
Air is fresh and healthy. Safe for all outdoor activities.
Acceptable air quality, though sensitive groups should monitor comfort.
Vulnerable groups (children, elderly) should limit outdoor exertion.
Everyone begins to experience health effects. Stay indoors where possible.
Significant health impact for entire population. Emergency conditions.
Serious health alert: everyone may experience serious life-threatening effects.
Fine particles are at minimal, safe levels. Air is optimal.
Acceptable air, but haze may be present in urban areas.
Individuals with heart or lung disease should limit activity.
Particulate levels high enough to cause respiratory irritation.
Heavy haze. High risk to cardiovascular health for the public.
Lethal particulate concentrations. Critical neurological and lung risk.
Low levels of dust and coarse particles. Environment is safe.
Coarse particles may trigger coughing in sensitive groups.
Visible dust pollution. Sensitive groups should avoid heavy labor.
Widespread respiratory impacts likely for the population.
Dangerous dust and debris levels. Significant warnings issued.
Extremely high concentrations. Stay inside with filtration.
Surface ozone levels are within a safe, natural range.
Acceptable air, but sensitive individuals may feel chest tightness.
Rising ozone can trigger airway inflammation in active children.
Avoid heavy outdoor work during the hottest part of the day.
Serious lung function reduction likely across the public.
Emergency ozone levels. Risk of permanent lung tissue damage.
Nitrogen levels are optimal. Safe for everyone.
Typical background levels for high-density urban areas.
Increased risk of respiratory infections for vulnerable groups.
Significant airway inflammation likely near traffic zones.
Acute respiratory distress potential. High-risk groups stay indoors.
Toxic concentrations. Immediate health precautions required.
Carbon Monoxide levels are clean and non-toxic.
Acceptable; may affect those with specific heart conditions.
Reduced oxygen delivery to the heart may occur.
Headaches and fatigue may occur in urban canyons.
Significant cardiovascular distress. Mental confusion possible.
Lethal potential. Immediate risk of neurological collapse.
Optimal air quality with no sulfur detection.
Acceptable air; minor odors possible near industry.
Bronchoconstriction possible for active asthmatics.
Respiratory distress likely for the wider population.

→ Slik leser du US EPA Air Quality Index før du går ut → Forstå nivåene i Air Quality Index og hva de betyr → Når tåke dannes og hva den gjør med luftkvalitetenHvordan beregnes denne AQI-en?
Den primære luftkvalitetsindeksen (AQI) vist ovenfor beregnes ved hjelp av US EPA Linear Interpolation-formelen basert på PM2.5-konsentrasjon (fine partikler).
- Nåværende PM2.5: 16.25 µg/m³
- Beregning: Byen din faller inn under kategorien «Moderat» (kategori 2).
Merk: Selv om flere forurensningsstoffer (O3, NO2, SO2) overvåkes, brukes PM2.5 som den primære «driveren» for hovedindeksverdien, da den vanligvis representerer den største helserisikoen.
Ofte stilte spørsmål
Hva er hovedårsaken til luftforurensning i Sittwe?
Forurensningen i Sittwe er hovedsakelig drevet av 10.8 km/h S vind, lokale trafikkutslipp og industriell aktivitet, som påvirker den nåværende PM2.5-konsentrasjonen på 16.25 µg/m³.
Er AQI-en i Sittwe trygg i dag?
Dagens AQI er 64, som er kategorisert som Moderat. Dette betyr at luftkvaliteten er moderat for den generelle befolkningen.
