Ten samples for each species were used for metal analysis. For sample preparation, acid digestion procedure was used. The concentration of metals was analyzed by Atomic Absorption Spectrophotometry (AAS) (AA-6300). In the muscles of the fishes studied, Fe was the highest accumulated metal (6.031 to 15.64ppm d.w) and Cu the lowest accumulated one (0.176 to 0.281 ppm d.w). The order of metal accumulation in the muscles of the fishes studied was Fe> Zn> Mn> Cu. The level of metals in the fishes studied was lower than the permissible limits of FAO/WHO guidelines except the level of Mn in Salmostoma sardinella but it seems not to be considered. ANOVA test was used to determine the differences of statistical means of the heavy metal concentration among fish species studied. The level of metals among six fishes studied was not statistically significant (p > 0.05). It can be concluded that from a public health point of view, fish commonly consumed by the local population in Magway Area do not seem to pose any significant human health risks due to metal exposure.
