			<onlyinclude>'''Air quality index''' ('''AQI''') is a metric developed to communicate levels of [[pollution]] over a given location.</onlyinclude> Arbitrary numbers are used to describe the risk that air pollution poses at any given moment (see Figure 1). AQI is determined by measuring the concentration of various pollutants such as [[particulate matter]], ground-level [[ozone]], [[carbon monoxide]] and sulphur dioxide.<ref name = oxford>C. Park and M. Allaby, A dictionary of environment and conservation. 2017 </ref> In a sense they can be looked at similarly to a [[weather]] report, as they inform an individual about the conditions of their [[environment]]. However, different countries have their own indices which correspond to differing [[air quality]] standards. This means that a "moderate" level of air pollution in one place might be considered "low-risk" in another. For example, the AQI in Canada is measured from 1-10, whereas in the UK it is measured from 0-500. Therefore, an AQI of 10 in the UK would be "low risk", whereas in Canada it would be considered "very high risk".
