Abstract

The methylmercury concentrations in three existing marine biological certified reference materials - TORT-1, DORM-1 and DOLT-1 - are determined by gas chromatography with electron capture detection, cold vapour atomic absorption spectrometry and inductively coupled plasma mass spectrometry after selective isolation of methylmercury. Two such procedures were used. These and the three analytical techniques are evaluated and compared. The certified methylmercury concentrations are: TORT-1, 0.128 ± 0.014; DORM-1, 0.731±0.060; and DOLT-1, 0.080 ± 0.011 Μg Hg/g dry weight. © 1989 Springer-Verlag.
