Air Quality Index (AQI) i Puerto Rico 🇵🇷
Live Air Quality Index (AQI) og PM2.5-niveauer i Puerto Rico
I øjeblikket måles luftkvalitetsindekset (AQI) i San Juan, hovedstaden i Puerto Rico, til en score på 43. Ifølge US EPA's sundhedsstandard kategoriseres denne luftkvalitetsvurdering som Good. Den nuværende atmosfære i San Juan er påvirket af en koncentration af PM2.5 (fine partikler) på 7.8 µg/m³ og PM10-niveauer registreret til 12.2 µg/m³. Overvågning af gasformige forureningsstoffer viser nitrogendioxid (NO2) på 1.6 µg/m³.
Ud over de primære bycentre varierer atmosfæriske forhold og smogniveauer på tværs af Puerto Rico baseret på industriel produktion, trafiktæthed og lokale vejrmønstre. Realtids forureningsdata og sundhedsadvarsler for luftvejene overvåges også aktivt i byer som Caguas, Guaynabo, Trujillo Alto og Mayagüez. At spore disse luftkvalitetsmålinger er afgørende for beboere i hele landet for at styre udendørs eksponering og opretholde åndedrætssikkerhed i perioder med øget partikelkoncentration.
Puerto Rico luftkvalitet: Indeks for større byer
* Luftkvalitetsindeks (AQI)-data for Puerto Rico beregnes efter US EPA-standarden. Oplysninger behandles fra flere overvågningsstationer, der registrerer PM2.5, PM10 og gasformige forurenende stoffer for at sikre nøjagtighed i forhold til planlægning af åndedrætssundhed.
Forståelse af luftkvalitetsniveauer
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.
