Template for Mercury in air or aerosols (draft)

This format should be used for submitting all relevant mercury species measured in gas phase and/or in aerosols

Points to note

  • Be careful in choosing the right component name and matrix combinations depending on your measurement procedure/instrument type. The following combinations are possible:

Component Name

Short Name

Matrix

Unit

 total_gaseous_mercury

 TGM

 air

 ng/m3   

 gaseous_elemental_mercury   

 GEM

 air

 ng/m3

 gaseous_oxidised_mercury

 GOM,RGM          

 air

 pg/m3

 Mercury

 

 air+aerosol

 ng/m3

 Mercury

 (PBM)

 aerosol,pm10,pm25  

 pg/m3

  • Specify further in the inlet description to distinguish between TGM and GEM when using monitors, i.e.: Heated inlet(50degC), Teflon filter and soda lime trap (GEM measured)or no trap (TGM measured)

  • Include information on routine checks and leak tests in the "Maintenance description" element

  • Include information on which standard pressure and temperature are used for conversion

  • Monitor data should be reported with one hour average, but several monitors sample with higher time resolution, i.e. five minutes. If so, report the standard deviation within each hour as a separate time series. Use the completeness flag (390-394) if low data coverage within the hour.

  • Include information if the instrument or lab have been part of any relevant laboratory intercomparison (ILC) or external audit, in the QA measures. Contact ebas@nilu.no if the ILC is not defined.

  • Include information on which SOP is used.

  • The template is describing measurements with monitor. For manual methods, relevant metadata for analytical method needs to be added

  • Boundary and Spike Checks: Submitted data will be checked for boundaries, the current specification for boundary checks can be found here.

Flags commonly used with this format:
