| Summary: | This study is focused on the determination of trace metals (Cr, Cu, Zn, As, Pb, and Cd) concentrations of nine different indigenous fish species of Meghna River in Bangladesh to know the possible risk in human consumption. Fishes' wet muscles samples were analyzed to evaluate the level of trace metal concentrations. The concentrations (mg kg(-1) w/w) of the six selected trace metals were in the order Zn (1.42 +/- 0.12) > Cr (1.31 +/- 0.08) > Cu (0.92 +/- 0.09) > Pb (0.54 +/- 0.07) > Cd (0.51 +/- 0.07) > As (0.47 +/- 0.02). The results revealed that all the selected trace metals were below the maximum permissible limits recommended by the reference standards. The fish species may pose no risk with respect to the Estimated Daily Intake (EDI). Target hazard quotient (THQ) values for Cr, Cu, Zn, Pb, and Cd in all the fish species were < 1.0, except for As which is dominantly organic in fishes. Both adults and children are vulnerable to carcinogenic health threat due to Cd exposure. |
