About the indicator

The mean annual concentration of suspended particles smaller than 2.5 micrometers, weighted by population — that is, the concentration residents are actually exposed to rather than the average across the territory. The WHO guideline of 2021 is no more than 5 µg/m³; in the most polluted countries values exceed it more than tenfold.
