Hazard Identification and Potential Risk Analysis of Toxic Metals in Redbelly Tilapia (Coptodon zillii) Consumed and Surface Water from the Niger Delta Estuary

Davies Ibienebo ChrisDumbari Koote NkeehAmaewhule Evelyn Godwin

Anthropogenic activities have led to the escalation of toxic metals, polluting rivers and accumulating in water, sediments, and fish. This damages aquatic ecosystems and has lasting effects on humans and aquatic life. The study aimed to determine the accumulation of heavy metals (Pb, Cr, Cu, Fe, Ni, Cd, and Zn) in Redbelly tilapia (Coptodon zillii) and water from three sampling stations along Atuka Creek in southern Nigeria, an oil-filled creek. The investigation also assessed potential health risks associated with consuming C. zillii, as well as the pollution and productivity levels of the aquatic ecosystem. Results indicated significant variations in heavy metal concentrations among stations, with Station 1 showing the highest contamination levels due to its proximity to pollution sources. Fish from Station 1 exhibited elevated contamination levels, exceeding WHO's recommended limits for Pb, Fe, Ni, and Zn. Calculations of chronic daily intake (CDI) values suggested potential health risks for both adults and children, especially at Stations 1 and 2. Hazard quotient (HQ) and hazard index (HI) values surpassed safe levels at these stations, indicating risks unrelated to cancer from consuming fish and swimming. Furthermore, assessments of lifetime cancer risk (ILCR and TLCR) revealed an increased cancer risk, particularly at Stations 1 and 2. These results underscore the necessity for stringent pollution control measures, regulations, and remediation strategies to address heavy metal contamination, maintain water quality, and protect public health in southern Nigerian communities.
