Percentage of population exposed to NO2 annual concentrations in urban areas, 1997-2009 (EU-27)
Note: new version is available!
The annual mean limit value is 40 µg NO2/m3 and to be met by 2010. Over the years 1997-2009 the total population, for which exposure estimates are made, increased from 54 to 118 million people due to an increasing number of monitoring stations reporting air quality data under the Exchange of Information Decision. Year-to-year variations in exposure classes are partly caused by the changes in spatial coverage. Only urban and sub-urban background monitoring stations have been included in the calculations. Data for Cyprus, Luxembourg and Malta, are not included due to the geographical coverage of the Urban Audit.
