This document specifies a method for the determination of organomercury in seafood by elemental
mercury analysis. The method has been successfully validated in an interlaboratory study on oyster
tissue, mussel tissue, lobster hepatopancreas, dogfish liver and tuna at levels from 0,01 mg/kg to
5 mg/kg referring to dry weight and expressed as mercury [1], [2].
The limit of quantification is approximately 0,01 mg/kg of organomercury [3], [4].
Organic species of mercury, other than monomethylmercury, are also extracted and thus determined
with this method. However, in seafood the contribution from organic species of mercury other than
monomethylmercury is negligible.Cross References:EN ISO 3696EN 13804ISO 5725-2:1994EN ISO/IEC 17025All current amendments available at time of purchase are included with the purchase of this document.
