Abstract: This study investigates the health risks associated with trace elements in Gorean snapper (Lutjanus goreensis) from Buguma Creek, Southern Nigeria. Fish samples were collected monthly from May to August 2023, and muscle tissues were analyzed for potential health risks posed by elevated levels of hazardous metals. The concentrations of various heavy metals (Fe, Zn, Pb, Cd, Cu, and As) in Gorean Snapper collected from different locations (Station 1, Station 2, and Station 3) were measured in milligrams per kilogram (mg/Kg) of fish tissue. Results revealed varying metal concentrations across stations, with notable differences in Fe, Zn, Pb, Cd, Cu, and As levels. The Estimated Daily Intake (EDI) values for Cadmium (Cd) were relatively low for both adults and children across all three stations. However, Lead (Pb) and Arsenic (As) exhibited low EDI values, while Zinc (Zn) showed significantly higher values, especially at Station 3. The Hazard Quotient (HQ) and Hazard Index (HI) results indicated potential health risks associated with Zinc exposure, particularly at Station 3, for both adults and children. Carcinogenic Risk (CR) analysis revealed potential health risks associated with long-term exposure to Cadmium for adults. The CR values for Lead and Arsenic fell within acceptable ranges. This study raises concerns about potential health risks associated with the consumption of L. goreensis from Buguma and recommends the continuous monitoring of heavy metal concentrations, public awareness programs, further research, collaboration among stakeholders, and the implementation of best practices in aquaculture and fisheries management to reduce heavy metal concentrations in fish.
