适用范围：This European Standard specifies a standard method for determining total gaseous mercury (TGM) in ambientair using cold vapour atomic absorption spectrometry (CVAAS), or cold vapour atomic fluorescencespectrometry (CVAFS).This European Standard is applicable to background sites that are in accordance with the requirements ofDirective 2004/107/EC and to urban and industrial sites.The performance characteristics of the method have been determined in comparative field validation testscarried out at four European locations: two background and two industrial sites. The method was tested fortwo months at each site over a period of twelve months using automated equipment currently used in Europefor determination of TGM in ambient air.The working range of the method covers the range of ambient air concentrations from those found atbackground sites, typically less than 2 ng/m3, up to those found at industrial sites where higher concentrationsare 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 293,15 K and 101,325 kPa, measuredover a specified time period, in nanograms per cubic metre.
