COMPARATIVE STUDY OF HEAVY METALS IN MAJOR PARTS OF CALLINECTES AMNICOLA(DE ROCHEBURNE) (CRUSTACEA: PORTUNIDAE) FROM WARRI RIVER, NIGERIAC.U. EDEMA AND A.B.M. EGBORGE
The levels of heavy metals in major parts of Callinectes amnicola from the Warri River were determined. The variation of the metals were in order of Mn> Fe> Pb> Cu> Cd in edible portion and gills. A slight variation was observed in carapace viz Mn> Fe> Cu> Pb> Cd. The concentrations of Fe, Pb and Mn were highest in the edible portion superlative to carapace and gills. Copper was highest in carapace while cadmium was highest in gills. As a result of this study, it is advisable that carapace and gills of C. amnicola should be disposed off at the pre-cooking stage of processing to reduce human uptake of toxic metals.
