Percentage of urban population resident in areas for days per year with ozone concentrations over the long-term objective for protection of human health, 1997-2009 (EU-27)
Note: new version is available!
The target value is 120 µg O3/m3 as daily maximum of 8 hour mean, not to be exceeded more than 25 days per calendar year, averaged over three years and to be achieved where possible by 2010. Over the years 1997-2009 the total population for which exposure estimates are made, increased from 47 to 114 million people due to an increasing number of monitoring stations reporting 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.
