| This study was carried out with the aim at the comparison of bioaccumulation capacity of nickel (Ni) and cadmium (Cd) in soft tissue such as muscle and gill and also two patch lengths (70±5 mm and 50±5 mm) of rock oyster (Sacostreacucullata) in the coastal province of Bushehr (Deir port) in the winter 2012. Totally, 135 oysters were collected from three stations, In order to determine the concentration of heavy metals in their tissues. Samples were transferred to the laboratory after biometry and isolating tissues. Concentrations of metals were measured using the Graphite Furnace Atomic Absorption Spectrophotometer (GFAAS). Moreover, samples of the sediment taken from each station to analyze the heavy metals.The data analysis of ANOVA one-way andDuncans Multiple Range testrevealed that the cadmium content of the samples of muscle and gill was higher than the nickel. There was significant differences (P<0.05) between the amount of cadmium and nickel.Cadmium average concentrations in samples of muscle and gill were reported as 2.53±0.45 and 6.87± 0.41ppm,respectively.The amount of nickel in muscle and gill were 0.76±0.64 and 1.09±0.42 ppm,respectively. In addition, the biological absorption of nickel and cadmium by the larger oyster’s patch reported as 1.86±0.59 and 6.05±2.25 ppmwhile the absorption of these metals by the smaller oyster’s group were calculated as 1.21±0.33 and 6.32±1.86 ppm, respectively. Thus, there were no significant differences (P>0.05) between the amount of cadmium and nickel in two patch lengths of rock oyster. The mean concentrations of Cd and Ni on sediment samples collected from three stations, reported as 1.43±0.86 and 1.37±1.11 ppm and showed no significant differences (P>0.05) between the amount of Cd and Ni in samples. |
