摘要：The concentration and pollution level of heavy metals in the surface sediments of Kendari Bay,Indonesia were measured. Sediments samples from 25 sites, ranging from the inshore (WangguRiver) to the offshore regions of the bay, were analysed for metal concentrations (i.e., Mn, Fe, Co, Ni,Cu and Zn), sediment type and TOC. The results demonstrate that the heavy metal Fe had the highestconcentrations (1100 to 29800 µg/g) followed by Mn (34.39 to 399.59 µg/g), Zn (2.58 to 129.70 µg/g),Ni (1.14 to 15.34 µg/g), Cu (0.6 to 15.81 µg/g), and Co (0.24 to 7.33 µg/g). Moreover, results of bothPearson correlation analysis and PCA suggest the similar distinctiveness of Fe, Co and Ni in 25sampling sites. The measurement results of index of geoaccumulation (Igeo) suggest that the KendariBay surface sediment is considered an unpolluted area for each of the heavy metals investigated inthis study.
