🇦🇺 Indeks kakovosti zraka (AQI) v Sydney, Australia
Zdravstvena priporočila za prebivalce Sydney
Kakovost zraka je zadovoljiva in onesnaženost zraka predstavlja majhno ali ničelno tveganje. To je odličen dan za dejavnosti na prostem v Sydney.

Kako brati indeks kakovosti zraka za Sydney
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.
Significant wheezing and shortness of breath likely.
Extreme respiratory danger. Significant life risk.

Primarni indeks kakovosti zraka (AQI), prikazan zgoraj, se izračuna s formulo US EPA Linear Interpolation na podlagi koncentracije PM2.5 (fini delci).
- Trenutni PM2.5: 11.6 µg/m³
- Izračun: Vaše mesto spada v kategorijo »Dober« (kategorija 1).
Opomba: Čeprav se spremlja več onesnaževal (O3, NO2, SO2), se PM2.5 uporablja kot primarni »gonilnik« glavnega indeksa, saj običajno predstavlja največje tveganje za zdravje.
Pogosta vprašanja
Kaj je glavni vzrok onesnaženosti zraka v mestu Sydney?
Onesnaženost v mestu Sydney je predvsem posledica vetrov s hitrostjo 17.6 km/h iz smeri WNW, lokalnih prometnih emisij in industrijske dejavnosti, kar vpliva na trenutno koncentracijo PM2.5, ki znaša 11.6 µg/m³.
Ali je AQI v mestu Sydney danes varen?
Današnji AQI je 56, kar je uvrščeno v kategorijo Dober. To pomeni, da je kakovost zraka dober za splošno populacijo.
