In this work, sampling collection strategies were compared for the determination of some heavy metals (Pb, Cr, Ni) and investigate their effects on the marine pollution. The sampling area is a natural bay using as a shipbuilding industries for three decades especially. To determine the permanent heavy metal pollution in this area, the sediment samples were taken different strategies; i) the bay were divided square pieces which is 200 m length, and the samples were taken this distance (total 71 point), ii) the samples were taken along the shore, then 200 m away the shore and 400 m away the shore (total 58 point). After the sample collection using ISO 5667-12 and EPA sampling procedure, the samples were prepared for the metal analysis. Acid treated samples were analyze by graphite furnace atomic absorption spectrometry. As a results both strategies were (are) compared for investigation of some heavy metals pollution in marine sediment. The preliminary results were found between below LOD and 401.0 mg/kg for lead, and between 0.10 and 1005.0 mg/kg for chromium. Finally, the permanent heavy metal pollution is investigated in this bay.
Key words: Heavy metals / marine sediment / sampling strategy
