Blood cockle (Anadara granosa) is one of the biotas which has high economic and ecological value in Cengkok Waters, Banten Bay. Human activities such as settlements, agriculture, fisheries, mining, and industries are seen as main reasons for degrading the aquatic environment and have a negative impact on blood cockles. Pb and Hg from these human activities may pollute the Cengkok Waters and accumulate in the body of blood cockles. This research aims to analyze the content of heavy metals (Pb and Hg) in blood cockles’ meat in Cengkok Waters, Banten Bay. Sampling was carried out monthly, from March to August 2019. Measurement of heavy metal contents was conducted using the AAS (Atomic Absorption Spectrophotometer). The result shows that the heavy metal contents (Pb and Hg) are still within the quality standard of Indonesian Food and Drug Authority (BPOM, 2018).
Banten Bay represents waters bordering the areas of marine tourism, industries, settlements, and agriculture. The wastes resulting from those activities can harm the aquatic environment. This study aims to analyze the bioaccumulation of heavy metals (Pb and Hg) in threadfin bream (Nemipterus sp.) in Panjang Island, Banten Bay, Banten Province. Sampling and observation were carried out from March to August 2019 on the island. Measurements of heavy metal contents in fish flesh and gills were conducted using the AAS (Atomic Absorption Spectrophotometer). Based on the results of analyses, Pb and Hg in fish flesh and gill were 0-0.149 mg/kg and 0-0.064 mg/kg, respectively, indicating that the number of heavy metals in the tissue was under the predetermined threshold; However, the number of heavy metals in the gill organs exceeded the predetermined threshold. The maximum weight limit of the fish flesh that can be consumed by both adults and children was 6.15 g/week and 1.85 g/week, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
