Abstract
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 (Wanggu River) 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 highest concentrations (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 both Pearson correlation analysis and PCA suggest the similar distinctiveness of Fe, Co and Ni in 25 sampling sites. The measurement results of index of geoaccumulation (Igeo) suggest that the Kendari Bay surface sediment is considered an unpolluted area for each of the heavy metals investigated in this study.
