This study employed recommended analytical procedures to determine the levels of As, Mn, Cu, Pb and Fe in whole Clarias anguillaris (mudfish) obtained from river Okpokwu, Apa Local Government Area. The concentrations of the heavy metals recorded in this study were below the WHO’s permissible limits. Therefore, water and Clarias anguillaris from the study area have not become contaminated by the heavy metals studied. However, periodic review should be sustained to monitor possible accumulations of the heavy metals in future due to the proliferation of anthropogenic activities around river Okpokwu.
