There are many countries with real-time Air Quality data inventoried on aqicn.org. For those not yet inventoried, you can find from this page a list of active monitoring coverage extension projects for selected countries:

Nigeria Egypt Cambodia Senegal Libya Morocco Tunisia Algeria Lebanon Qatar Pakistan


If you live in a Country not yet inventoried, and you would like to see it as part of the monitoring coverage extension, then please send us an inquiry via the form below.

New Country Inquiry

Air Quality monitoring is not a simple thing, and there are existing criteria and standards for publishing data.

The equipment needed for monitoring Air Pollution is not only expensive (at least $10K per monitor) but also requires professional knowledge for their setup and maintenance - and that's a full time job.

For this reason, managing country, region or city level monitoring network is usually done by government representatives (usually linked to the environmental ministry) or by institutions certified by the government for doing so (for instance the EPA is US).

However, sometimes, some countries needs a some help for setting up or improving their monitoring network. This is where the World Air Quality Index project can help. If you are living in such a country and would like to see the real-time Air Quality data published on our map, then send us a message now.

关于空气质量与空气污染指数

本网站采用的污染指数和颜色与EPA是完全相同的。 EPA的指数可以从 AirNow上查到

空气质量指数 空气质量指数级别(状况)及表示颜色 对健康影响情况 建议采取的措施
0 - 50 一级(优) 空气质量令人满意,基本无空气污染 各类人群可正常活动
51 -100 二级(良) 空气质量可接受,但某些污染物可能对极少数异常敏感人群健康有较弱影响 极少数异常敏感人群应减少户外活动
101-150 三级(轻度污染) 易感人群症状有轻度加剧,健康人群出现刺激症状 儿童、老年人及心脏病、呼吸系统疾病患者应减少长时间、高强度的户外锻炼
151-200 四级(中度污染) 进一步加剧易感人群症状,可能对健康人群心脏、呼吸系统有影响 儿童、老年人及心脏病、呼吸系统疾病患者避免长时间、高强度的户外锻炼,一般人群适量减少户外运动
201-300 五级(重度污染) 心脏病和肺病患者症状显著加剧,运动耐受力降低,健康人群普遍出现症状 儿童、老年人及心脏病、肺病患者应停留在室内,停止户外运动,一般人群减少户外运动
300+ 六级(严重污染) 健康人群运动耐受力降低,有明显强烈症状,提前出现某些疾病 儿童、老年人和病人应停留在室内,避免体力消耗,一般人群避免户外活动
