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.

这项研究的重点是测定孟加拉国Meghna河的9种不同本土鱼类的痕量金属（Cr，Cu，Zn，As，Pb和Cd）浓度，以了解人类食用的潜在风险。对鱼的湿肌肉样品进行了分析，以评估痕量金属的浓度。浓度（mg kg ^-1六种选定的痕量金属的w / w顺序为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）。结果表明，所有选定的痕量金属均低于参考标准所建议的最大允许限值。就估计的每日摄入量（EDI）而言，鱼类可能没有任何风险。除了鱼类中有机质占优势的砷外，所有鱼类中铬，铜，锌，铅和镉的目标危害商（THQ）值均<1.0。成人和儿童都容易受到由于接触Cd致癌的健康威胁。
