Concentrations of total and inorganic arsenic (dry wt) and percentages of inorganic arsenic in four aquacultural fish species were not significantly different from those found in natural fish. Inorganic arsenic levels found in the four fish species from both sources in this study were much lower than the Thai regulatory standard of 2 μg/g, and hence are considered safe for human consumption. © Springer Science+Business Media New York 2012.Mahidol UniversityEnvironmental SciencePharmacology, Toxicology and PharmaceuticsArticleSCOPUS10.1007/s00128-012-0858-6
