Praegune ilm asukohas Port-au-Prince
Kuidas lugeda õhukvaliteedi indeksit Port-au-Prince
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.

Ülal näidatud peamine õhukvaliteedi indeks (AQI) arvutatakse US EPA lineaarse interpolatsiooni valemi abil, mis põhineb PM2.5 kontsentratsioonil (peened tahked osakesed).
- Praegune PM2.5: 45.650001525878906 µg/m³
- Arvutus: Teie linn kuulub kategooriasse "Ebatervislik (tundlikele rühmadele)" (kategooria 3).
Märkus: Kuigi jälgitakse mitmeid saasteaineid (O3, NO2, SO2), kasutatakse PM2.5 peamise indeksi väärtuse "mootorina", kuna see kujutab endast tavaliselt suurimat terviseriski.
Korduma Kippuvad Küsimused
Mis on peamine õhusaaste põhjus linnas Port-au-Prince?
Saaste linnas Port-au-Prince on peamiselt tingitud 6.1 km/h SE tuultest, kohalikust liiklusheitest ja tööstustegevusest, mis mõjutavad praegust PM2.5 kontsentratsiooni 45.650001525878906 µg/m³.
Kas AQI linnas Port-au-Prince on täna ohutu?
Tänane AQI on 126, mis on liigitatud kui Ebatervislik (tundlikele rühmadele). See tähendab, et õhukvaliteet on ebatervislik (tundlikele rühmadele) üldisele elanikkonnale.
