PS 36-2 - Potential human health risk assessment associated with consumption of fish contaminated by heavy metals in the Korle Lagoon, Ghana

Abstract: The consumption of fish contaminated with heavy metals is a significant public health concern globally. In this study, we conducted a human health risk assessment to evaluate the potential health risks associated with the consumption of contaminated fish. We collected fish samples from the Korle Lagoon and analyzed them for the presence of heavy metals, including lead, cadmium, and arsenic. The concentrations of these metals were then used to estimate the daily intake of heavy metals by the population, based on consumption patterns and body weight. Our results showed that the concentrations of heavy metals in the fish samples were higher than the maximum permissible levels set by regulatory agencies. The estimated daily intake of heavy metals through fish consumption exceeded the safe limits recommended by international agencies, which could pose significant health risks to the population. The study highlights the urgent need for effective monitoring of seafood safety and the implementation of measures to reduce the levels of heavy metals in fish. Additionally, there is a need for public awareness campaigns to inform the population about the potential health risks associated with the consumption of contaminated fish and the importance of reducing exposure to heavy metals. Overall, this study provides valuable information for policymakers and regulators to make informed decisions regarding the safety of seafood and the protection of public health.
