Bioavailability assessment of essential metals in freshwater crab (Potamon ebonyicum) at Ebonyi River Basin Nigeria


Author(s): Rupert C Akpaniteaku and Precious A Udeozor

Abstract: Bioaccumulation of selective essential metals: Magnesium (Mg), iron (Fe), zinc (Zn), selenium (Se) and copper (Cu) in the cephalothorax, cheliped and leg of Potamon ebonyicum was analysed using Atomic Absorption Spectrophotometer (AAS). The metals were found at various concentration levels in the body parts of male and female. The concentrations decreased in the following order: Male: Cu< Se< Fe < Zn < Mg and in the female: Cu < Se < Zn < Fe < Mg. The amount of Fe in the cephalothorax of the female was higher than in the other body parts of both sexes. All the metals analysed were found at levels within the NRC recommended dietary allowances. Based on the bioaccumulation in the different body parts, it is concluded that the crab species is relatively wholesome for consumption and cultivation
