Context: Accumulation of toxic metals in aquatic organisms is one of the most important problems facing the world today since these metals can enter the food chain and have a damaging impact on human health. Aims: This research determines the concentration of metals (cadmium [Cd], arsenic [As]) in the soft tissue of blue swimmer crab (Portunus pelagicus) from four different stations along the Asalouyeh coasts in Iran. Settings and Design: The West suburb of the Mond protected area in Bushehr Province was chosen as a control area. Samples were collected over a 3-month period during winter of 2014. Materials and Methods: Metal analysis was performed by atomic absorption spectrophotometer. Surface water at each sampling station was measured for selected physicochemical parameters with a multiparameter meter. Statistical Analysis Used: Analysis of variance followed by Duncan test (α = 0.05) was applied to determine the differences between the groups. Results: The results showed that the mean concentration (mg/kg dry weight) of Cd in the crab was higher than As. The concentration of both metals was higher in March. The highest concentration of Cd (1.54 ± 0.07) and As (0.35 ± 0.01) in the samples was observed for station 1 which was near to industrial zone of Asalouyeh. The mean concentrations of both metals were significantly (P = 0.000) higher in the study area than in the control area. Conclusions: Results showed that P. pelagicus is a reliable biological indicator of Cd and As contamination. The concentration of Cd in the crab samples was higher than recommended levels. Therefore, it is not suitable for consumption. |
