Percentage of population exposed to NO2 annual concentrations in urban areas, EEA member countries, 1996-2005
Data prior to 1996 with a coverage of less than 50 million people are not representative for the European situation. Year-to-year variations in exposure classes are partly caused by changes in spatial coverage. Only urban background stations have been included in the calculations.
