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).
