🇭🇰 Indeks kvalitete zraka (AQI) u Sham Shui Po, Hong Kong
Zdravstvene preporuke za stanovnike Sham Shui Po
Kvaliteta zraka je prihvatljiva. Međutim, za neke zagađivače može postojati umjeren zdravstveni rizik za vrlo mali broj ljudi. Osjetljive skupine trebale bi razmotriti smanjenje dugotrajnog napora na otvorenom.

Kako čitati indeks kvalitete zraka za Sham Shui Po
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.

Primarni indeks kvalitete zraka (AQI) prikazan gore izračunava se pomoću formule US EPA Linear Interpolation na temelju koncentracije PM2.5 (fine čestice).
- Trenutni PM2.5: 18.45 µg/m³
- Izračun: Vaš grad spada u kategoriju "Umjereno" (Kategorija 2).
Napomena: Iako se prati nekoliko zagađivača (O3, NO2, SO2), PM2.5 se koristi kao primarni "pokretač" glavne vrijednosti indeksa jer obično predstavlja najveći zdravstveni rizik.
Često postavljana pitanja
Koji je glavni uzrok onečišćenja zraka u Sham Shui Po?
Onečišćenje u Sham Shui Po uglavnom je uzrokovano vjetrom brzine 9.7 km/h iz smjera SSW, lokalnim prometnim emisijama i industrijskom aktivnošću, što utječe na trenutnu koncentraciju PM2.5 od 18.45 µg/m³.
Je li AQI u Sham Shui Po danas siguran?
Današnji AQI je 68, što je kategorizirano kao Umjereno. To znači da je kvaliteta zraka umjereno za opću populaciju.
