Analysis of Pb, Cu and Zn Metal Content in Sediments and Blood Cockles (Anadara granosa) in the Waters of Bangko Rokan Hilir

ABSTRAK

Bangko waters are located in Bangko Rokan Hilir District, drained by the Rokan River and bordering the Malacca Strait, influenced by various coastal activities that have the potential to provide input of pollutants, such as heavy metals and accumulate in the bodies of biota. This condition can also threaten the ecosystem and the lives of aquatic biota, as Bangko waters are known as the centre of shellfish production in Riau Province. This study aims to determine the concentrations of Pb, Cu, and Zn in sediments and blood cockles, and to analyze the relationships between metal concentrations and levels of metal pollution in Bangko waters. Sediment and blood cockle sampling was conducted in the waters of Bangko, where people collect cockles for consumption or trade. The results showed that the highest metal content in sediment was Cu (6.208µg/g), while in blood cockles, the highest metal content was Zn (12.407µg/g). As the metal content of the sediment increases, the metal content of the blood cockles also increases. The I-geo value of Bangko waters falls into the category of unpolluted to moderately polluted. In contrast, the MPI value shows that the metal content in Bangko waters is still classified as a low level of pollution when compared to studies that have the same characteristics
