Abstract
Concentrations of nine heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pd and Zn) were determined "in; imported frozen'fish namely Mackerel (Scomber scolnbrus)^ ' Striped red mullet (Mullus surmuletus), Groster argentine {A rgentina silus), Commen pandora (Pagellus erytlvinus) and Atlantic horse mackerel (Trachurus trachurus). The average concentrations of the heavy metals analyzed exhibited the following decreasing order: Fe > Zn > Pb > Co > Cu > Cr > Mn > Ni > Cd. The concentrations of the studied heavy metals in fish tissues were lower than the Effect Range-Low (ERL) for such fish, while gill and liver exhibited elevation over the ERL for Cd only. The metal pollution index (MPI) for most studied fish fluctuated between 0.90 and 4.42 with average 2.18 for wet weight. The ingestion of heavy metals and the calculated lifetime daily intake have been reported and do not represent any actual risk due to the low concentrations of heavy metals in the studied fish tissues. These results suggest that the studied imported frozen fish might be considered as unpolluted with heavy metal.
