Abstract

The Sungsang area in the Musi River estuary is an important fishing ground that is potentially exposed to zinc (Zn) contamination due to intensive anthropogenic activities. This study aimed to analyze Zn accumulation in mantis shrimp (Harpiosquilla raphidea) and to evaluate its consumption safety. Samples were collected from local collectors and analyzed using flame atomic absorption spectrophotometry in accordance with SNI 2354-13:2014. The results showed that Zn concentrations ranged from 20.24 to 21.27 mg/kg, with an average of 20.70 mg/kg, remaining below the maximum permissible limit established by Dirjen POM (1989). Risk assessment based on estimated intake indicated that Zn exposure from mantis shrimp consumption is within safe limits for humans. Overall, these findings confirm that mantis shrimp from Sungsang are safe for consumption with respect to Zn contamination. This study provides scientific evidence for food safety assessment and underscores the need for continuous monitoring of heavy metal contamination to support sustainable coastal resource management.

Abstract

Estuaries are intermediate environments that are extremely susceptible to pollution, especially heavy metals like manganese (Mn). The goals of this research were to determine the amount of manganese in the consumable flesh of Jerbung shrimp (Penaeus merguiensis) taken from the Sungsang Estuary in Banyuasin Regency, South Sumatra, Indonesia, and to ascertain the safe intake levels for people. Atomic Absorption Spectrophotometry (AAS) was used to analyze the shrimp samples at a wavelength of 257. 61 nm. According to the findings, the average Mn content in shrimp muscle was somewhat higher than the limit set by the European Food Safety Authority (EFSA), falling between 3. 16 and 3. 21 mg/kg. Even if just shrimp are consumed, the projected consumption limits based on dietary intake calculations still suggest a comparatively low immediate health risk. However, the high Mn concentration indicates the effect of environmental pollution brought about by human actions in the Musi River estuary. These findings emphasize the significance of controlling pollution sources and carrying out routine environmental monitoring to ensure the safety of seafood and the sustainability of estuarine ecosystems.
