| Abstract | ||||
| Mantis shrimp (Squilla mantis) is a popular and affordable seafood in the coastal regions of the Mediterranean Sea. It is commonly consumed due to its accessibility and nutritional value, particularly its richness in omega-3 fatty acids. As a predatory crustacean of commercial importance, S. mantis also serves as a potential biomarker for marine pollution since it can bioaccumulate heavy metals such as mercury. Mercury contamination in marine ecosystems poses serious risks to human health through seafood consumption, and the accumulation of mercury in S. mantis has become an emerging concern in environmental toxicology and food safety. In control mantis shrimp samples, the estimated daily intake (EDI) of mercury was 0.159, lower than the recommended reference dose (RfD). Correspondingly, the health risk (HR) and target hazard quotient (THQ) values were 0.318 and 0.13, respectively, suggesting negligible immediate risk to human consumers. However, prolonged exposure to mercury, even at low concentrations, can still result in adverse health effects. Curcumin, the active compound in Curcuma longa, is known for its strong metal-chelating properties. This study investigated the effect of curcumin extract on mercury residues in S. mantis under controlled conditions. A total of 24 samples were collected from fish markets in Port-Said City, Egypt, and divided into four groups: control, 0.5% curcumin-treated, 0.5% curcumin with boiling, and 2% curcumin-treated. Results showed a significant reduction in mercury levels, with the 0.5% curcumin plus boiling treatment achieving complete elimination of mercury residues. | ||||
