Concentrations of both essential (Zn and Cu) and non essential (As, Cd, Pb, Hg, Ni) metals were measured in the organs (mantle, branchial hearts, gill and digestive gland) of Sepia pharaoniscaptured in coastal water of Bushehr Province on thePersian Gulf (Iran). The relationships between S. pharaonis size (mantle length) and metals concentrations in tissues were investigated by linear regression analysis. Metals concentration (as µg/ g d.w.) was highest in the digestive gland and lowest in the mantle of S. pharaonis, except for Ni. The concentrations of metals were found to follow the order: Zn> Cu>Pb> Ni>Hg> Cd> As. The mean Zn concentrations ranged from 37.72± 5.32 to 9.32± 3.73 µg/ g d.w, whereas the mean As concentrations ranged from 0.01± 0.007 to 0.06± 0.05 µg/ g d.w, respectively. Results of linear regression analysis showed that significant relationships between metal concentrations and fish size were positive, except for the cadmium in the gill. Levels of metals determined in mantle of the Pharaoh cuttlefish were within the range of value legally defined as safe for human consumption, except forPb. The digestive gland of S. pharaonis would seem to constitute a good potential indicator of heavy metal concentrations in the marine environmental.

Lead, mercury, cadmium and iron concentration in following tissues: muscle, liver and gill of Liza abu in Karoun and Kharkheh were measured. Karoun and Kharkheh are important rivers in Iran. Significant variation in metal values were evaluated using Student’s t test at p < 0.05. Result showed that maximum concentration of metals were recorded in gill tissues. Iron concentration was higher than lead, cadmium and mercury in different organs (p < 0.05). The level of metals Cd, Hg, Fe in different tissues of Karoun river was higher than Karkheh river (p < 0.05). Metals level in different tissue were upper than WHO standard.

Research was performed to investigate the concentration of mercury in muscle and liver of fish species from freshwater (Barbus xanthopterus, Barbus grypus, Liza abu) and saltwater (Cynoglossus arel, Periophthalmus waltoni, Otolithes ruber) in Khouzestan, Iran. In freshwater fish, muscle was polluted in comparison with liver except for Barbus xanthopterus which high levels of mercury were measured in liver. In saltwater fish liver was contaminated than muscle except for Cynoglossus arel which high level of mercury was found in muscle. Significant variations in metal values were evaluated using student’s t test at P < 0.05. Mercury concentrations were well above the permissible limits suggested by WHO and FDA guidelines.

Cadmium, lead, nickel and mercury were contamination in gill, liver and muscle of B. grypus and B. xanthopterus in Karoon and Dez Rivers. Significant variations in metal values were evaluated using student’s t test at p < 0.05. In B. grypus high levels of cadmium, lead, nickel and mercury were measured in gill (1.49, 2.25, 1.02 and 0.89 mg kg−1 dw) except for mercury (1.06 mg kg−1 dw) in B. grypus in Dez River was high in liver. In B. xanthopterus high levels of cadmium, lead, nickel and mercury were measured in gill (2.17, 2.91 and 1.43 mg kg−1 dw) except for mercury (1.42 mg kg−1 dw) high levels were measured in liver.
