Abstract. Trace metals in the sediments non-residual fraction and their relative abundance in various sedimentary components from the culture bed ofAnadara granosa were investigated. High levels of Cd (40%), Ni (40%), and Pb (43%) were associated with the sediment exchangeable phase (EP). The sediment moderately reducible phase (MRP) was more predominant than the easily reducible phase (ERP) and the organic sulphide phase (OSP) in the sorption of available trace metals. However, this area was not considered to be heavily impacted by trace metal pollution. Since there was no significant concentration gradients observed in sediments and bivalves collected from all stations, trace metal enrichment factors were determined. A. granosa collected from this area was enriched by Zn, Cu, Pb, Ni, Cd, and Ni.
