Tiger Cuttlefish-Sepia pharaonis – Herenberg 1831-is a is a seafood species that belongs to five fishing stations in the Bahrakan Bay ( the waters of the Persian Gulf). 3specimens of Cuttlefish-Sepia pharaonis –, regardless of being male or female specimens, have been caught.The amount of these heavy metals by using atomic absorption spectrophotometer (AAS) was determined.The Range of concentrations of the heavy metals on the basis of dry weight, respectively is: The Concentrations of Cd, Cu, Pb in the samples of Cuttlefish -Sepia pharaonis- 0.54 to 0.25,3.98 to 2.12and from 0.09-0.03 (mg / kg)were measured. The level of contamination by heavy metals in Cuttlefish -Sepia pharaonis- of the Bahrakan Bay-Persian Gulf Shows that the amount of heavy metals in the species of Cuttlefish -Sepia pharaonis- that is studied on ,according to the standard of US FDA ,is within the limits permitted for human consumption and The results reveal that the concentration of the metals can be compared in this way: Cu>Pb> Cd. As a result of this study, acorrelation between climatic parameters (5 different locations of Cuttlefish -Sepia pharaonis-live in the Bahrakan Bay) and accumulation of heavy metals were found in the Cuttlefish -Sepia pharaonis-.To select the location of Cuttlefish-Sepia pharaonis – fishing as you go from the province of Khuzestan to Bushehr , the contamination by heavy metals: lead, copper, cadmium, in this fish will behigher.

Abstract
Tissue metal accumulations (gills, liver, kidney and muscle) in Persian sturgeon (Acipenser persicus) were compared folowing exposure to sublethal levels of waterborne Cd (50, 400 and 1000 μg•L-1) after periods of 1, 2, 4 and 14 days. The obtained results indicate that at the end of 4 and 14 ...

Tissue metal accumulations (gills, liver, kidney and muscle) in Persian sturgeon (Acipenser persicus) were compared folowing exposure to sublethal levels of waterborne Cd (50, 400 and 1000 μg•L-1) after periods of 1, 2, 4 and 14 days. The obtained results indicate that at the end of 4 and 14 days of exposure, total tissue cadmium concentration followed the pattern: liver > gill > kidney > muscle. Calculation of bioconcentration factor (BCF) after 14 days exposure showed that at low and high concentrations, highest BCFs were found in kidney and liver, respectively. According to the results, the accumulation capacity of muscle was the lowest at all exposure concentrations. Cd concentration in the cytosol of experimental tissues were measured and the results indicated that Cd levels in the cytosol of liver, kidney and gills increased 240.71, 32.05, and 40.16-fold, respectively 14 days after exposure to 1000 μgL-1 Cd. The accumulation of Cd in cytosol of tissues is in the order of liver> gills> kidney.
