PM2.5 air pollution, mean annual exposure (micrograms per cubic meter)

Definition

Population-weighted exposure to ambient PM2.5 pollution is defined as the average level of exposure of a nation's population to concentrations of suspended particles measuring less than 2.5 microns in aerodynamic diameter, which are capable of penetrating deep into the respiratory tract and causing severe health damage. Exposure is calculated by weighting mean annual concentrations of PM2.5 by population in both urban and rural areas.

Type of figure

Modelled estimate. Produced by a statistical model that combines surveys and other data, often to fill years without a survey. It is not a direct measurement.
