Abstract

• Seven metals concentrations in the muscular tissue of 15 fish species and water and sediments collected from Ayeyawady River segment of Salay environs were seasonally examined by Flame Atomic Absorption Spectrometer (FAAS) (Perkin Elmer AAanalyst 800 and Winlab-32 software) in Universities' Research Centre (URC) during the period from February 2015 to January 2016. The mean concentrations of toxic metals in all studied fishes with different feeding habits were lower than the WHO permissible limits except the arsenic in cold season. However essential metal concentrations were found within the permissible FAO range. The cadmium concentrations of water in rainy and cold seasons and arsenic in cold season were higher than WHO guideline values. Essential metal concentrations of water were within the WHO permissible limits. Toxic metals of sediments were within probable effect concentrations (PEC).
