Certified reference materials for mercury in soils and sediments

It is therefore of primary interest to have samples from sediments since this is the starting point of the food chain.

The main issues (see the related information below) to be controlled during the analysis of sediments for the speciation analysis of mercury are:
  • quantitativeness of extraction of the species from the sediment/soil
  • absence of artificial formation of methylmercury during the analytical procedure
  • control of contamination mainly for inorganic mercury
  • control of the derivatization yield
  • avoidance of ion-exchange and adsorption problems on GC column packing materials
CRMs play a major role in the development and validation of methods and for quality control. The following certified reference materials (CRMs) are available for the speciation of mercury species in soils and sediments:
Estuarine sediment
Total and methyl mercury
IAEA 405
Estuarine sediment
Trace metals, mercury and methylmercury
Marine sediment
Trace metals, mercury and methylmercury
Estuarine sediment
Total and methyl mercury
