Distribution and Speciation of heavy metals (Cd, Cu and Ni) in coastal sediments of Dumai Sumatera, Indonesia
Heavy metal concentrations in sediment collected from Dumai coastal waters have been studied by using sequential extraction technique to determine the distribution and geochemical speciation (EFLE, acid reducible, oxidisable organic and resistant) of Cd, Cu and Ni. The results showed that the hig...

| description | Heavy metal concentrations in sediment collected from Dumai coastal waters have been studied
by using sequential extraction technique to determine the distribution and geochemical speciation
(EFLE, acid reducible, oxidisable organic and resistant) of Cd, Cu and Ni. The results showed that the
highest concentrations of total Cd was in Cargo Port area and the lowest in Penyembal, whilst for Cu
and Ni the highest concentrations were in Ferry Port and the lowest in Batu Panjang. The total
concentrations of Cd, Cu and Ni ranged from 0.65 – 1.82, 1.84 – 13.16 and 7.68 – 17.98 μg/g dry
weight, respectively. Higher metal concentrations were detected in the eastern and central parts of
Dumai city center where most of anthropogenic activities are concentrated. However, most of the
concentrations of Cd, Cu and Ni were still below the ERL and ERM values. Only at few stations,
especially in the eastern and central parts of Dumai, showed Cd concentrations exceed the ERL but still
well below the ERM values. Metal concentrations in 78.26% (Cd) and 91.30% (Cu and Ni) of the
sampling stations were dominated by resistant fraction indicating natural origin of these metals. Non
resistant fractions, however, were found higher than resistant fractions at Pelintung, Pertamina, Cargo
Port, Penyembal and Batu Panjang for Cd; Penyembal and Batu Panjang for Cu and Pelintung and
Guntung for Ni. These findings indicated that anthropogenic inputs of Cd, Cu and Ni occurred in these
stations. For all sampling site groups, Cd, Cu and Ni were mostly accumulated in the resistant fraction
(55.28 – 58.31%; 65.02 – 91.84% and 50.08 – 66.88% of the total concentrations respectively) which
indicated that the mobility and anthropogenic inputs of these metals in Dumai coastal waters were quite
low. |
