Comparison of heavy metals in razor clams (solen sp.) of Asajaya and Muara Tebas
Pb, Fe, Zn, Cu, Cd and Mn contents in razor clams (Solen sp) and sediments were measured using Flame Atomic Absorption Spectrophotometer (FAAS).

| Summary: | Pb, Fe, Zn, Cu, Cd and Mn contents in razor clams (Solen sp) and sediments were measured using Flame Atomic Absorption Spectrophotometer (FAAS). Razor clams from both sampling sites showed the similar patterns in accumulating heavy metals. Tissues of razor clams recorded highest concentrations of Fe and Zn, while shells accumulated highest concentration of Pb and Mn. The concentrations of Cu and Cd were low in razor clams from both sampling sites. Based on FAO limits, Pb concentration in shells of razor clams was more than the designated limit at both sampling sites. The heavy metal concentrations in sediments were also measured and it was higher than razor clams. This study revealed that sediments from Muara Tebas were slightly polluted with Pb. There were significant correlations between Cu concentrations in tissues of razor clams with the sediments (r =0.7459) at Asajaya Laut. |
