Determination of selenium in fish by hydride generation Atomic Absorption Spectrometry.


Hydride generation atomic absorption spectrometric method was used for the determination of selenium in fish. Different parts of the most important six species of fish Cyprins carpio, Barbus luteus, Liza abu, Tilapia zillii, Barbus sharpeyi and Tenaulosa ilisha is the diet of the local population , have been analyzed after wet destruction with a mixture of concentrated acids (HClO4/HNO3).Tissue analysis of Barbus sharpeyi reveals that liver accumulates the highest amount of selenium .No correlations were observed between selenium levels in the fish and season of collection, length, sex and age of fish. . The values obtained are compared with literature data and selenium contents in fish muscle.
