Annual changes in concentrations of PM10, O3 and NO2 in the period 2001–2010
-
Statistically significant trends (level of significance 0.1) are calculated by applying the Mann-Kendall test. The trend slopes are indicated with coloured dots when statistically significant. Red dots indicate increasing concentrations. The applied method is described in de Leeuw, 2012

Annual mean NO2 concentration observed at (sub)urban background stations, EEA member countries, 1997-2008
-
Only urban and sub-urban background monitoring stations have been included in the calculations. Data for Bosnia and Herzegovina, Iceland, Liechtenstein, Luxembourg, Malta, the former Yugoslav Republic of Macedonia, Serbia, and Turkey are not included due to the geographical coverage of the Urban Audit and/or lack of air quality data.

Annual mean NO2 concentration observed at traffic stations, 2009 - Annual mean PM10 concentration observed at traffic stations, 2009
-
The two highest NO2 concentration classes (red and orange) correspond to the 2010 annual LV (40 μg/m3) and to the LV plus margin of tolerance (42 μg/m3).
The two highest PM10 concentration classes (red and orange) correspond to the 2005 annual LV (40 μg/m3), and to a statistically derived level (31 μg/m3) corresponding to the 2005 daily LV. The lowest class corresponds to the WHO air
quality guideline for PM10 of 20 μg/m3.

Annual mean NO2 concentration observed at urban background stations, 1997-2009 (EU-27)
-
The figuer shows the annual mean NO2 concentration observed at urban background stations. 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.

Annual mean NO2 concentration observed at urban background stations, 2001-2010 (EU-27)
-
Only urban and sub-urban background monitoring stations have been included in the calculations. Data for Cyprus and Malta are not included due to missing availability of operational urban and sub-urban background monitoring stations in the Urban Audit cities.

Assessment of ground-level ozone in EEA member countries, with a focus on long-term trends
-
European countries have significantly reduced anthropogenic emissions of ozone precursor gases since 1990. In general, however, ambient air measurements in urban and rural areas of Europe do not show any downward trends in ground-level ozone. The main purpose of this report is to shed light on possible reasons.
