      2014年3月中國空氣質量指數監測城市排行榜(當月31天各項數據平均值)

      數據更新時間:2014年4月1日

      注:達標天數為AQI達標天數。按照中國定于2016年1月1日起在全區范圍內實施與世界衛生組織“過渡時期目標-1”等同的GB 3095-2012《環境空氣質量標準》執行。

      以當月排名第三的湛江的達標天數為例:18/31,第一個數字代表湛江當月空氣質量達優的天數(AQI<=50),第二個數字代表湛江當月空氣質量達良(含優)的天數(AQI<=100),供參考。

      按照世界衛生組織PM2.5年均值低于10μg/m3為安全值,目前中國尚無城市達標,最好的空氣也許在海南。

      指標說明:AQI=空氣質量指數;PM2.5=細顆粒物;PM10=可吸入顆粒物;CO=一氧化碳; NO2=二氧化氮;SO2=二氧化硫;O3-1h=臭氧1小時平均;O3-8h=臭氧8小時平均;

      數值單位:μg/m3(CO為mg/m3)
      AQI排名190個城市AQIPM2.5PM10CONO2SO203-1hO3-8h達標天數
