Accumulation of Heavy Metals (Cu, Ni, Pb, Cd) in the Sediment and Razor Clam, Solen Roseomaculatus in the Shorelines of Bushehr Province

In order to determine heavy metals contamination in sediment and razor clams from Bushehr intertidal, samples were collected from 5 stations, including Khor Lailatain, Imam Hassan Port, Khor Genaveh, Rig Port and Shif Island. The samples were dried, acid digested and analyzed for their metals content using atomic absorption spectrophotometer. According to the results, the concentrations of Cu, Ni, Pb and Cd in the sediment of the mentioned stations ranged 5.6- 14.75, 19.67-58.72, 7.96-13.92 and 0.68-0.96 μ/g respectively. The concentration of the same metals in soft tissues of razor clam was 5.36-27.84, 0.24-2.72, 5.64-10.04 and 0.32-1.8 μ/g while in the shells they ranged 10.75-21.25, 1.36-3.52, 4.28-8.08 and 0.68-0.96 μ/g respectively. Generally the concentration of the studied metals in both sediment and clams was lower than proposed FAO and USEPA standards
