Determination of arsenic in fish by hydride generation atomic absorption spectrometry.
A method utilizing microwave dissolution in a closed Teflon bomb followed by hydride generation atomic absorption spectrometry has been used for the routine analysis of arsenic in fish species from the coast of the province of Granada, Spain. The technique was evaluated for decomposing biological standard reference material (BCR mussel tissue) for arsenic analyses. The precision of the results ranged from 2.78 to 6.99%. The recovery percentages ranged from 96.33 to 100.00%. The values determined in the samples indicated slight contamination by this element in the zone. The concentrations of arsenic in fish ranged from 0.396 to 45.716 micrograms/g.
