Abstract:

Cadmium (Cd) and Lead (Pb) concentrations were estimated in the abdomenal muscle (edible portion) and cephalothorax of the pink shrimp Penaeus notialis. The shrimps were purchased from the Creek road market, the most populated fish market in Port Harcourt, Nigeria. Morphometric measurement (total lenght in cm and weight in g) of six shrimps was made. The carapace and hard covering of the abdomen was removed and the fleshy parts as well as the cephalothorax were analyzed for Cd and Pb by flame atomic absorption spectrophotometric (AAS model GBC AvantaPm AAS). The abdomenal concentrations of Cd ranged from 0.06 to 0.30 mg/kg and 0.41 to 0.98 mg/kg for Pb. In the cephalothorax Cd concentrations ranged from 0.16 to 1.25 mg/kg, while Pb concentrations were 0.78 to 1.95 mg/kg. These concentrations were higher than the WHO and FAO permissible limit of 0.1 g/g for Cd and 0.2 g/g for Pb. The concentration of Pb was significantly higher than the concentration of Cd in both the cephalothorax and abdomen of the shrimp and concentrations in the cephalothorax were significantly higher than in the abdomen. A risk assessment and hazard quotient was estimated for Cd for children, teenagers, women of child bearing age and adults
