2013年5月中国空气质量指数监测城市排行榜(当月31天各项数据平均值)

数据更新时间:2013年6月1日

注:达标天数为AQI达标天数。按照中国定于2016年1月1日起在全区范围内实施与世界卫生组织“过渡时期目标-1”等同的GB 3095-2012《环境空气质量标准》执行。

以当月排名第三的深圳的达标天数为例:18/31,第一个数字代表深圳当月空气质量达优的天数(AQI<=50),第二个数字代表深圳当月空气质量达良(含优)的天数(AQI<=100),供参考。

按照世界卫生组织PM2.5年均值低于10μg/m3为安全值,目前中国尚无城市达标,最好的空气也许在海南。

指标说明:AQI=空气质量指数;PM2.5=细颗粒物;PM10=可吸入颗粒物;CO=一氧化碳; NO2=二氧化氮;SO2=二氧化硫;O3-1h=臭氧1小时平均;O3-8h=臭氧8小时平均;

数值单位:μg/m3(CO为mg/m3)
