This study was conducted to determine some heavy metals such as lead and mercury contained in dried crayfish gotten from three different locations (Oron, Ataba and Nembe town in Akwa Ibom, Rivers and Bayelsa State respectively) and sold in the Creek Road Market, Borokiri, Port Harcourt, Rivers State. The dried crayfish samples were purchased randomly from marketers in the market. 5g of the dried crayfish Original Research Article
