Particulate matter (PM10), 2010 - Daily limit value for the protection of human health
-
In the air quality directive (2008/EC/50), the EU has set two limit values for particulate matter (PM10) for the protection of human health: the PM10 daily mean value may not exceed 50 micrograms per cubic metre (µg/m3) more than 35 times in a year and the PM10 annual mean value may not exceed 40 micrograms per cubic metre (µg/m3). In some areas time extensions have been granted by DG Environment for meeting these limit values. Information about time extensions is provided by DG Environment at: http://ec.europa.eu/environment/air/quality/legislation/time_extensions.htm

Nitrogen dioxide 2010 - Annual limit values 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.

Carbon monoxide 2010 - 8 hour mean limit value for the protection of human health
-
In the air quality directive (2008/EC/50), the EU has set a limit value for carbon monoxide (CO) for the protection of human health: the CO maximum daily 8-hour mean values may not exceed 10 milligrams per cubic metre (mg/m3).

Sulphur dioxide 2010 - Winter limit value for the protection of ecosystems
-
In the air quality directive (2008/EC/50), the EU has set two limit values for sulphur dioxide (SO2) for the protection of vegetation within the zones designated by member states: the SO2 annual mean value may not exceed 20 micrograms per cubic metre (µg/m3) and the SO2 mean value for the winter period (1 October to 31 March) may not exceed 20 micrograms per cubic metre (µg/m3).

Benzene 2010 - Annual limit value for the protection of human health
-
In the air quality directive (2008/EC/50), the EU has set a limit value for benzene (C6H6) for the protection of human health: the annual mean value may not exceed 5 micrograms per cubic metre (µg/m3). The limit value comes into effect for data measured from 1 January 2010. During 2009 a margin of tolerance was in place so the annual mean should not exceed 6 micrograms per cubic metre (µg/m3).
