Figure C source code header Nitrogen dioxide - Hourly limit value for the protection of human health
In the air quality directive (2008/EC/50), the EU has set two limit values for nitrogen dioxide (NO2) for the protection of human health: the NO2 hourly mean value may not exceed 200 micrograms per cubic metre (µg/m3) more than 18 times in a year and the NO2 annual mean value may not exceed 40 micrograms per cubic metre (µg/m3). These limit values come into force for concentrations measured from 1.1.2010 so during 2009 a margin of tolerance equal to an annual mean value of 42 micrograms per cubic metre (μg/m3) is still in place

Figure Nitrogen oxide - Annual limit value for the protection of vegetation
In the air quality directive (2008/EC/50), the EU has set a critical level for nitrogen oxides (NOx) for the protection of vegetation within the zones designated by member states: the NOx annual mean value may not exceed 30 micrograms per cubic metre (µg/m3).

Highlight Ozone and particulates most serious air quality problems in Europe
Air quality in Europe has improved between 1990 and 2009, as emissions of most pollutants have fallen, according to a new report from the European Environment Agency (EEA). But there is still a lot of room for improvement, as many EU countries are expected to exceed the emissions ceilings in 2010 for at least one pollutant. In addition, concentration levels of ground-level ozone and particulate matter have remained stable over recent years despite efforts to improve air quality.
