Heavy Metal Concentration (Cd, Cr, Cu, Pb, Zn) in Marine Biota in Benoa Bay Waters, Bali

Marine biota resources have an important role in improving the economy of coastal communities. Utilization of marine biota can be influenced by the quality of the environment such as the presence of heavy metal content in marine biota. Heavy metals can enter the tissues of living things through several ways, namely the respiratory tract, digestion and skin penetration. The purpose of this study was to determine the content of heavy metals (Cd, Cr, Cu, Pb, Zn) in marine biota and the types of marine biota that are utilized by the people in the Benoa Bay waters. In this study, the determination of the sampling point is done by purposive sampling which refers to the area of ​​capture of marine biota by fishermen or the community. Marine biota samples obtained will be identified and measured morphometrically. Further samples were taken at each location of 0.5 kg. Samples are taken in good and fresh conditions and will be analyzed by heavy metal concentrations (Cd, Cr, Cu, Pb, Zn) by wet ashing preparation methods and analyzed by AAS (Atomic Absorbsion Spectrophotometry) at the MIPA Analytical and Integrated Laboratory.
