Abstract
Abstract Banten Bay potentially receives pollutants such as heavy metals from various anthropogenic activities operating around the bay. Cengkok Coastal Waters, as part of Banten Bay, has a variety of fishery commodities, including green mussels ( Perna viridis ). This paper identifies the risks of heavy metal contamination by quantifying the bioaccumulation of Pb and Hg in the green mussel tissue. The study was conducted from March to August 2019. Analytical results indicate concentrations of Pb and Hg in the range of 0.005-0.044 mg/kg and 0.012-0.036 mg/kg, respectively. These results were still below the established national standards by SNI (2009) for fresh food and BPOM (2018) for processed food. These concentrations suggest that green mussel found in Cengkok Coastal Waters and surrounding areas are still suitable for consumption by the local community as long as they do not exceed the permissible limits, namely, 0.7 kg meat/week (for children) and 2.4 kg meat/week (for adults).
