Abstract: The content of arsenic was determined in the rainbow trout muscle (Oncorhynchus mykiss) and in rice samples. The method of atomic absorption spectrometry with hydride generation (HG-AAS) in graphite furnace was used for total arsenic determination. Arsenic speciation was done using the high performance liquid chromatography-hydride generation-atomic fluorescence spectrometry (HPLC-HG-AFS). The rainbow trout muscle was extracted by ultra pure deionised water; trifluoroacetic acid was used for the extraction of rice samples. Total arsenic values ranged from 60.90 μg/kg to 310.00 μg/kg in rice samples and from 0.72 mg/kg to 2.23 mg/kg in rainbow trout muscle. An inorganic trivalent arsenic As(III) was determined as the main species in rice and non-toxic arsenobetaine in the samples of rainbow trout.
