The WHO Ambient Air Quality Database compiles data on ground measurements of annual mean concentrations of nitrogen dioxide (NO2), particulate matter of a diameter equal or smaller than 10 μm (PM10) or equal or smaller than 2.5 μm (PM2.5) which aim at representing an average for the city or town as a whole, rather than for individual stations. Both groups of pollutants originate mainly from human activities related to fossil fuel combustion. In order to present air quality data that represent human exposure, we used mainly urban measurements, comprising urban background, residential areas, commercial and mixed areas or rural areas and industrial areas close to urban settlements.

The United Nations Statistical Division (UNSD) develops the Environment Statistics Database that contains data received through the Questionnaire on Environment Statistics. With the improvement of coverage and data quality, the Environment Statistics Database will gradually provide the basis for regular dissemination of environment statistics. UNSD environmental indicators derived from these data are now available.
