摘要：It is feared that the metal mineral exploration could lead to mining waste in the form of heavy metals that pollute water and sediments in the coastal areas of Sangihe Islands Regency, North Sulawesi Province. The objective of this research was to investigate the concentration and quality status of heavy metals inside the water and sediment with regard to possibility of potential pollutants at the mariculture existing and potential sites. The research was carried out in coastal areas of Bays of Talengan, Manalu, and Dagho and surrounding areas by sampling of water and sediments and then analyzed in the laboratory for heavy metals of Cu, Fe, Hg, Pb, and Zn. Descriptive statistics were used to analyze existing data and then used Storet (Storage and Retrieval) method to determine the quality status of water and sediment of heavy metals for marine organisms. The results showed that from 5 heavy metals analyzed in water and sediment were found 4 of them i.e. Cu, Fe, Pb, and Zn were detected and 1 other was undetected i.e. Hg in the coastal areas of Sangihe Islands Regency. Results of quality status determination of water and sediment indicate that water of coastal areas of Sangihe Islands Regency was classified as heavily polluted from heavy metals of Cu and Pb for marine organisms, while sediment was classified as an appropriate quality standard of heavy metal for marine organisms. Concentrations of heavy metals of Cu and Pb inside the water have exceeded the heavy metal quality standard for marine organisms.
