Abstract: This research is aimed at assessing the level of the heavy metals: Copper (Cu), Chromium (Cr), Cobalt (Co), Cadmium (Cd), Iron (Fe), lead (Pb), Nikel (Ni), Silver (Ag), Zinc (Zn), and Manganese (Mn) in some fish organs, water and sediment from Maladumba and Fada Darm Misau Local Government Area Bauchi State. The organs (gut, gills, liver and flesh) of Mudfish (Clariasanguillaris), Tilapia (Oreochromisniloticus), water and sediment were collected and prepared from two different sites. Prepared samples were digested using freshly prepared aqua Regia method with an acid mixture of (HNO3 + H2SO4 + HClO4) in the ratio (2:1:1). Analysis of the samples was done using Atomic Absorption Spectroscopy (AAS). This study revealed that majority of the sample analyzed contained Cd, Mn and Cu Concentration above WHO’S maximum permissible level of these metals, these result agrees with other finding reported from Sharada and Jakara Kano State, Nigeria. In this study Ag was not detected in all the samples, this may be due to the below detection limit of the analytical technique used. The high concentration of heavy metals obtained in this study may be due to Agricultural and Ceramic industrial activities within the study area. Results showed that the Fish from Maladumba And Fada Ponds may be consumed with the exception of Pb, Cd Mn and to some extent Cu, and Fe in Water, Sediment, and some fish organs that indicates above maximum permissible limits. To sustain a healthy freshwater ecosystem and prevent health problem to the locals, concentration of heavy metals should be monitored regularly. Appropriate measure such as legislative provision and other tools for effective and environmental monitoring should be mounted and used with a view to protecting and enhancing the better quality and resources of these Dams.
