Abstract

Tuna fish flesh homogenate, IAEA-436, a certified reference material received from IAEA under the Analytical Quality
Control Services intercomparison programme for trace metal determination, was analyzed for Cu, Fe, K, Mg, Mn and Zn
by using atomic absorption spectrophotometric (AAS) technique employing the optimized instrumental parameters. The
reliability of the methodology adopted was checked by analyzing IAEA-CRM (Copepod Homogenate MA-A-1) under
identical conditions and comparing the results obtained with the certified values which are in quite good agreement with
each other. High precision was observed for Fe, K, Mg and Zn, whereas Cu and Mn showed relatively poor precision in
their determination.
