In order to evaluate accuracy, certified reference materials (Fish protein, NRCC - Dorm 4 and fish material, Ipen - Dourada 1) were analyzed after extraction and separation of mercury species. Good agreement of the results have been obtained (relative error of the determination between the methods varied from 1.5 % to 39 %). The repeatability of the results varied from 4 % to 26 %.1-4openAccesschemical analysismercurycomparative evaluationsfishescalibration standardsabsorption spectroscopyaccuracymethylmercuryArtigo de periódico73310.1088/1742-6596/733/1/012022https://orcid.org/0000-0002-6745-8185
