Heavy Metal Contents Of Hg, Cd, Pb, And Cu In Blue Swimming Crab (Portunus Pelagicus) In Banten Bay, Indonesia

Abstract

Bojonegara coast, Banten Bay is an industrial zone in the West Serang region, which is characterized by the presence of some factories around the coast. These have potential to produce and pour the pollutants such as heavy metals into the water and accumulate into the body of aquatic organisms like blue swimming crab. This study aims to analyze the level of heavy metal accumulation in the blue swimming crab (Portunus pelagicus) of Banten Bay waters. Sampling was carried out from August to October 2020. Analysis of heavy metal content was carried out using AAS (Atomic Absorption Spectrophotometer). During the observation, the heavy metal content of Hg, Cd, Pb, and Cu were significantly different between large and small blue swimming crab (p<0,05). The accumulation of heavy metal Cu in small blue swimming crab ranged from 3,22-4,34 mg kg−1 and large blue swimming crab ranged from 6,64-9,52 mg kg−1 while the heavy metal content of Hg, Cd, and Pb in small crabs was below detection AAS. Bioaccumulation of Cu in blue swimming included moderate to high, while heavy metal Hg, Cd, and Pb it was low accumulation. The safe limit for consumption blue swimming crab is 22,0588 kg of meat/week for adults and 5,5147 kg of meat/week for children.
