Nyíregyháza空氣污染：詳細污染物分析
如何解讀空氣質素指數 Nyíregyháza
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.
這個 AQI 是如何計算的？
上面顯示的主要空氣質量指數（AQI）是使用美國 EPA 線性插值公式，基於PM2.5濃度（細顆粒物）計算的。
- 當前 PM2.5： 10.05 µg/m³
- 計算： 你的城市屬於「良好」類別（類別 1）。
注意：雖然會監測多種污染物（O3、NO2、SO2），但 PM2.5 被用作主要指數值的「驅動因素」，因為它通常代表最高的健康風險。
常見問題
Nyíregyháza 空氣污染的主要原因是什麼？
Nyíregyháza 的污染主要受 23.8 公里/小時的 N 風、本地交通排放和工業活動影響，這些因素導致了當前 PM2.5 濃度為 10.05 µg/m³。
今天 Nyíregyháza 的 AQI 安全嗎？
今天的 AQI 為 53，屬於 良好 類別。這意味著空氣質量對一般人群 良好。
