Cd and Pb Concentration in Muscle and Liver Tissues of Flathead (Platycephalus indicus) in the Northeastern Persian Gulf

This study was conducted to determine Pb (Pb) and Cd (Cd) concentrations in the liver and muscle of Platycephalus indicus (flathead) in Minab, Qeshm Island and Khamir Port in the Northeastern Persian Gulf. Moreover, the influences of season (winter and summer) and target tissue (liver and muscle) on the Pb and Cd concentrations in flathead were investigated and compared with FAO/WHO standards for human consumptions. Sampling was done in three stations (Minab, Qeshm Island and Khamir Port) and within two seasons (winter and summer). Thirty samples were prepared per season per station. The concentration of metals (Pb and Cd) was measured using Atomic Absorption Spectrometry (AAS). The results showed that metal levels differred significantly (P<0.05) between stations, seasons and organs. The concentrations of Pb and Cd in the muscle of flathead fish were below the FAO/ WHO standard values indicating flathed fishes in Minab, Qeshm Island and Khamir port were safe for human consumptions.
