A study was conducted from December 2017 to September 2018 to assess the concentrations of some elements (Cu, Zn, As, Cd and Pb) in the muscles of two fish species, Cirrhinus mrigala (herbivore) and Wallago attu (carnivore) from the Ayeyawady River segment, Magway Township. The mean values of selected elements in C.mrigala were -0.230 mg/L for Cu, 0.452 mg/L for Zn, -1.154 mg/L for As, 0.118 mg/L for Cd and -0.026 mg/L for Pb. In W.attu, the mean concentrations of selected elements were -0.264mg/L, 0.657 mg/L, -4.238 mg/L, 0.066 mg/L, and 0.865mg/L for Cu, Zn, As, Cd, and Pb respectively.
