Percentage of the EU urban population potentially exposed to NO2 concentration over the limit value set for protection of human health, 2002–2011

The NO2 monitoring data in AirBase provide the
basis for estimating the exposure of the European
population to exceedances of the NO2 annual mean
limit value of 40 µg/m3. Figure 4.4 presents this data
for the period 2002–2011, based on NO2 measured
at urban background monitoring stations.
