This European Standard describes a standard method for determining total gaseous mercury (TGM) in ambient air using cold vapour atomic absorption spectrometry (CVAAS), cold vapour atomic fluorescence spectrometry (CVAFS) or Zeeman atomic absorption spectrometry (Zeeman AAS). This European Standard is applicable to background sites that are in accordance with the requirements of Directive 2004/107/EC and to urban and industrial sites. The performance characteristics of the method have been determined in comparative field validation tests carried out at four European locations: two background and two industrial sites. The method was tested for 2 months at each site over a period of 12 months using automated equipment currently used in Europe for determination of TGM in ambient air. The working range of the method covers the range of ambient air concentrations from those found at background sites, typically less than 2 ng/m³, up to those found at industrial sites where higher concentrations are expected. A maximum daily average up to 300 ng/m3 was measured during the field trials. Results are reported as the average mass of TGM per volume of air at 293 K and 101,325 kPa, measured over a specified time period, in ng/m3.
