Determination of heavy metals in razor clam (solen sp.) at Moyan and Hulu Langat
Razor clam ( Solen sp) was used to determine the levels of heavy metals (Cd, Mn, Fe, Cr and Hg). The samples were collected at three different stations at Moyan and also from Hulu Langat. The determination of heavy metals in sediments and different parts of razor clam (shell, tissue, foot, siphon an...

| 总结: | Razor clam ( Solen sp) was used to determine the levels of heavy metals (Cd, Mn, Fe, Cr and Hg). The samples were collected at three different stations at Moyan and also from Hulu Langat. The determination of heavy metals in sediments and different parts of razor clam (shell, tissue, foot, siphon and gill) was carried out using Flame Atomic Absorption Spectrophotometer (FAAS) and Flow Injection Mercury Spectrometer (FIMS). Fe was found to be the most abundant element in sediments, tissue, foot, siphon and gill parts of razor clam while Mn occurred in highest concentration in shell. Hg was found in lowest concentration in sediments and also in all parts of razor clam. The accumulation of heavy metals in Moyan and Hulu Langat varied between different parts. There were significant correlations for Cd in sediment and Cd in shell, tissue, foot, and siphon (r > 0.76, P<0.05). Concentration of Mn in tissues significantly correlated with Mn in sediment (r= 0.72, P=0.05). |
