Trace Element Concentrations Present in Five Species of Freshwater Fish of Bangladesh

Abstract

In the present study, the edible portions of whole fish excluding viscera and bone of five different freshwater fish species samples are analysed for lead, manganese, nickel, zinc, copper and iron by atomic absorption spectrophotometry (AAS). The relative standard deviations (RSD) were found below 5%. The accuracy of the methods was confirmed by certified reference materials. The concentrations of trace elements in the edible portions of other fish comply with the international standards for human consumption.
