This study aims to demonstrate the performance of the inductively coupled plasma mass spectrometry (ICP-MS) following hot plate heating digestion method for marine fauna samples. About 100 to 200 mg of lobster hepatopancreas certified reference materials (CRMs; TORT-3 from National Research Council Canada) in each sample was processed the hot plate heating digestion procedure before analyzing 12 trace metals (Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Cd, Hg and Pb) by ICP-MS. Total 26 CRMs samples in 21 separate batches were analyzed in this study. The recovery of all other studied metals ranged from 90.37 to 106.02%, except Cr. Almost recovery results were less than 100%, thus it confirmed that the contamination of all laboratory apparatuses was not significant. The accuracy results showed that this analytical procedure can be applied to determine some trace metals in marine benthos samples.
