Bioaccumulation of lead (Pb) and mercury (Hg) in green mussel Perna viridis (Linnaeus, 1758) in Cengkok Coastal Waters, Banten Bay, Indonesia

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).

Analysis of heavy metals content Hg, Cd, Pb, and Cu of green mussel Perna viridis (Linnaeus, 1758) in Bojonegara Coastal Waters of Banten Bay, Indonesia

“…Cadmium metal (Cd) waste comes from agricultural waste (use of inorganic fertilizers and pesticides), battery industry, and plastic stabilizers [22]. According to [8], lead (Pb) metal waste comes from industrial activities, domestic waste, agricultural waste.Heavy metal copper (Cu) is an essential heavy metal needed by the body of living organism in small amounts. The source of heavy metal copper (Cu) in the waters of Banten Bay comes from ship transportation activities and steam power plant (PLTU) activities that use coal.…”

“…There have been many studies to the content of heavy metals in shellfish, including [6] studied heavy metals in mud clam (Geloina erosa) in East Segara Anakan and West of the Donan River (Cilacap), [7] studied heavy metals in green mussels (Perna viridis) in Trimulyo waters (Semarang), and [8] observed heavy metals in green mussels (Perna viridis) in Cengkok Coastal Waters, Banten Bay. In addition, research related to heavy metals in aquatic biota in Banten Bay were carried out, including [9] studied heavy metals in crab (Portunus pelagicus), [10] studied heavy metal in swimming crab (Scylla serrata), and [11] observed heavy metal in mud grouper (Epinephelus coioides).…”

Heavy Metals (Hg, Cd, Pb, Cu) in Greenback Mullets (Planiliza subviridis Valenciennes, 1836) from Bojonegara coastal waters, Banten Bay, Indonesia

“…Mullets Planiliza subviridis (Valenciennes, 1836) are one of the fish species living in the waters of the estuary with high tolerance to changes in water conditions, and the ability to adapt to a variety of food in their habitat (Nuringtyas et al, 2019). Research related to heavy metals in biota in the waters of Banten Bay has been carried out by several researchers, including the blue swimming crab (Febrianessa et al, 2020) and green mussels in Cengkok coastal waters (Melinda et al, 2021). These studies showed that the heavy metals that contained in the flesh of biota were still below the values of the quality standards.…”

Heavy Metal Contents of Hg, Cd, Pb, and Cu in Mud Crab (Scylla Serrata) in Banten Bay, Indonesia

“…Research on heavy metals in several other biota in Banten Bay were carried out by several researchers, including mud crab [7], blue swimming crab [8], green mussels [9], blood cockle [10] at Cengkok Beach, Banten Bay waters. Research related to the ecology of the Banten Bay waters was carried out by [11] and [12].…”
