Topics
Air quality index Confidence: 89% Arrow up

An air quality index (AQI) is a number used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become.

As the AQI increases, an increasingly large percentage of the population is likely to experience increasingly severe adverse health effects.

Different countries have their own air quality indices, corresponding to different national air quality standards.

Some of these are the Air Quality Health Index (Canada), the Air Pollution Index (Malaysia), and the Pollutant Standards Index (Singapore).
Air pollution Confidence: 78% Arrow up

Air pollution occurs when harmful substances including particulates and biological molecules are introduced into Earth's atmosphere.

It may cause diseases, allergies or death in humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment.

Human activity and natural processes can both generate air pollution.
