        This study was carried out to determine the heavy metal content ( Pb and Cd) in muscle and liver tissues of Pomadasys kakaan   in Bandar Abbas during winter 2011 and summer 2012. After biometry of the fish, muscle and liver tissues were separated. The amount of Pb and Cd were measured by atomic absorption spectroscopy (Varian model GTA 100). Based on the results, the average concentration of Pb and Cd in liver tissues were observed to be 0.1334±0.0234 and 0.0255±0.0077 µg/g respectively and in muscle tissues 0.0439±0.0106 and 0.0041±0.0007 µg/g, respectively. The difference between the average concentration of Pb and Cd in liver and muscle tissues is significant (P<0.05). Average accumulation of Pb and Cd in liver and muscle tissues were not difference significantly between two seasons (P>0/05). The comparison of the results with permissible limits of WHO and EPA showed that the concentrations of these metals are low. Manuscript profile

        To survey and compare heavy metal (Pb, Cd) accumulation in Carangoides  malabaricus  in Persian Gulf waters (Hormozgan Province), sampling of this fish catches was done seasonally from Tiab port to Bandar Abass city during winter and summer of 2012. After biom More
        To survey and compare heavy metal (Pb, Cd) accumulation in Carangoides  malabaricus  in Persian Gulf waters (Hormozgan Province), sampling of this fish catches was done seasonally from Tiab port to Bandar Abass city during winter and summer of 2012. After biometry of the fish, muscle and liver tissues were separated. The amount of Pb and Cd were measured by an atomic absorption instrument (Varian - model GTA 100).The results of lead concentration in liver and muscle tissues were 0.1470±0.235 and 0.0399±0.0125 µg/g, respectivelyand Cd levels in liver and muscle tissues were 0.0297±0.0105 and 0.0036±0.0005 µg/g respectively.. The difference between the average concentration of Pb and Cd in liver and muscle tissues was significant (p<0.05). Average concentrations of Pb and Cd in liver and muscle tissues were not difference significantly between two seasons (p≥0/05). The comparison of the results with permissible limits of WHO, EPA and UK showed that the concentrations of these metals are lower than international permissible limits. Manuscript profile

        Shark cartilage, liver and muscle may have an inhibitory effect on mutagenicity and accordingly there is a correlation between antimutagenesis and anticarcinogenesis. The use of antimutagens and anticarcinogens in everyday life is the most effective procedure to preventing human cancer and genetic diseases. In this research, we studied the effects of cartilage, muscle and liver extracts of family Sphyrnidae in Persian Gulf on antimutagenicity and antioxidant by Ames test, using Salmonella typhimurium strains in the second phase, especially in the presence and absence of liver microsomal fraction (S9). The number of revertant colonies was compared with negative and positive controls. The results showed that, percentage of antimutagenic and antioxidant effect of cartilage was around 90%. Cartilage extract showed stronger antimutagenic effect in comparison with muscle and liver extracts.Antimutagenic substances may prevent cancer because they can destroy mutagens both inside and outside body cells, and block mutagens that damage DNA and cause mutation in cells. These extracts exhibited an antimutagenic activity that could be beneficial in late as well as early stages of cancer development Manuscript profile
