Abstract
Banten Bay is an area affected by industrial, shipping, and domestic activities. These have the potential to produce wastes in the form of heavy metals and can accumulate in the body of aquatic organisms such as the splendid ponyfish Eubleekeria splendens (Cuvier, 1829). This study aimed to determine the accumulation of heavy metals Hg, Cd, Pb, and Cu in splendid ponyfish Eubleekeria splendens (Cuvier, 1829) meat in Banten Bay, Serang Regency, Banten Province. Sampling was carried out for three months, from August to October 2020. Analysis of heavy metal content was carried out using AAS (Atomic Absorption Spectrophotometer). The content of heavy metals Hg, Cd, Pb, and Cu in splendid ponyfish meat were <0.030 mg/kg, <0.001 mg/kg, <0.005 mg/kg, and 0.224-0.437 mg/kg. Bioaccumulation of heavy metals Hg, Cd, Pb, and Cu in small and big splendid ponyfish meat has a low accumulation rate. During the observation period, the heavy metal content of Hg, Cd, Pb, and Cu in small and big splendid ponyfish meat was not significantly different.
Highlights
Banten Bay is a relatively shallow water area with an area of ± 150 km2 [1]
Industrial activities around Banten Bay include the Suralaya Steam Power Plant, the plastic raw material industry, the chemicals industry, the steel industry, the sugar industry, and shipping activities that can contribute to heavy metal pollution in the waters [2]

Summary
Industrial activities around Banten Bay include the Suralaya Steam Power Plant, the plastic raw material industry, the chemicals industry, the steel industry, the sugar industry, and shipping activities that can contribute to heavy metal pollution in the waters [2]. Heavy metals are harmful contaminants in the aquatic environment because they have complex degradation properties, are readily soluble in water, settle in sediments, and accumulate in marine organisms [3]. Sources of heavy metal waste in Banten Bays’ waters, especially Bojonegara, are dominated by anthropogenic activities or human activities in the environment. Heavy metals can accumulate mainly in the river and marine sediments [6] because metals can be bound to organic and inorganic compounds through the adsorption process and the formation of complex mixtures.
