Analysis and Determination of Trace Metals (Nickel, Cadmium, Chromium, and Lead)‎ in Tissues of Pampus argenteus and Platycephalus indicus in the Hara Reserve, Iran

الملخص EN

The accumulations of Cd, Ni, Pb, and Cr were measured in muscle, gill, kidney, and liver of Platycephalus indicus and Pampus argenteus.

Our results indicated that all metals were found to be the highest in tissues in P.

indicus (benthic species).

Except Ni in P.

indicus, concentrations of metals and bioaccumulation factor were in the following sequence: liver > kidney > gill > muscle.

The data revealed that there is a significant negative correlation between concentrations of metals and size and age factors.

The Ni and Cr levels in the muscles were higher than the maximum acceptable limit recommended by WHO and FEPA.

Similarly, the concentration of Pb measured in P.

indicus muscle exceeded the FAO standard limit.
