PM2.5

Indicator: Air quality in agglomerations

A graph for three air pollutants shows the extent to which the WHO recommendations from 2021 will be exceeded on average in urban areas between 2000 and 2024. The development of the various pollutants varies. Between 2000 and 2024, values for NO2 are between 172 and 28 percent, for ozone between 44 and 28 percent and for PM2.5 between 255 and 61 percent
