Distribution of some trace metals in B. luteus fish collected from Main outfall drain and its concentration in blood of local fishermen

الملخص EN

The present study was carried out to assess the levels of six metals Pb, Cd, Ni, Mn, Co and Cu in different tissues of B.luteus from Al-Masab Alamm also Cd and Pb in blood samples of local fishermen.

The levels of heavy metals were analyzed by flam atomic absorption spectrophotometer(FAAS).

Total levels in muscle, gill, liver and kidney tissues of the fish showed a wide range.

The order of heavy metals concentration in muscle Mn> Cu> Ni> Co> Pb> Cd , in gills Mn> Pb> Ni> Cu> Co> Cd, in liver Mn> Co> Cu> Pb> Ni> Cd and in kidney Mn> Pb> Cd> Cu> Co> Ni.

The present study showed differences in metal concentrations in different tissues.

The range of metals concentration in blood were (0.003-0.014) µg/g Cd and ( 1.6- 2.3) µg/g Pb.

The estimated values of all metals concentration in muscle of fish and blood human in this study were below the established values.
