Abstract

The present study reports the presence of metal concentrations (Zn, Cu, Cd, Pb, Hg, and Cr) in the edible tissue of mantis shrimp (Harpiosquilla harpax de Hann, 1844) collected from the eastern region of Java Sea, Indonesia. The concentrations of metals in the muscle tissues of mantis shrimp were determined by atomic absorption spectrometry. The concentrations of metals ranged from 18.6 to 27.3 mg kg for Zn, 11.5 to 15.5 mg kg for Cu, 1.5 to 1.6 mg kg for Cd, 1.4 to 1.5 mg kg for Pb, 0.04 to 0.06 g kg for Hg, and 0.02 to 0.03 g kg for Cr. The metals concentrations in the analyzed muscles of mantis shrimp were in the order: Zn >Cu>Cd>Pb>Hg>Cr. The levels of Cd in mantis shrimp from the eastern coast of Java Sea exceed the permissible limit for human consumption, according to WHO, FAO, EC, and Indonesia standards, while the levels of Pb exceed the FAO and EC standards. The estimated weekly intakes (EWI) of Zn, Cu, Hg, and Cr were below the recommended values: 7000, 3500, 5.6 and 15 g kg−1 body weight (BW), respectively. Meanwhile, the EWIs of Cd and Pb were higher and very close to the recommended values: 7 and 25 g kg−1 BW, respectively. To minimize the health risk due to the negative effects of Cd and Pb, it is necessary to reduce the consumption of this mantis shrimp.
