Abstract
Study was carried out on the Pollution Status of Kwabateri Reservoir in Michika Local Government, AdamawaSstate, Nigeria. Water and fish for the heavy metal determination collected from study area twice a month in triplicate from (3) different sites (site I which is the inlet, site II the center, and site III, the outlet) for the period of 4 months (June to September, 2021). Some physico-chemical parameters were determined at the site while Heavy metal in water and C. gariepinus were determined using Atomic Absorption Spectrometer. A significant difference (P<0.05) was reported in temperature, ammonia, Dissolved Oxygen, pH, turbidity and Conductivity in relation to months in this study. A significant difference (P<0.05) in Lead, Iron, Cadmium, Copper and Chromium with regards to months was reported in this study. A significant difference (P<0.05) in Lead, Iron, Cadmium and Copper was also reported in C. gariepinus in relation to months in this study. Physico-chemical parameters of Kwabateri Reservoir have significant differences between months except for Ammonia that has no significant different (P>0.05) and is within the recommended level of WHO, NESREA and FAO. The results obtained in this study also showed wide mean concentrations of the heavy metals in the reservoir with iron (Fe) and Chromium (Cr) recording the highest and lowest levels respectively. Apart from Lead (Pb), Cadmium (Cd) and Chromium (Cr) with the present concentrations within the guideline permissible limits, the mean concentrations of the other heavy metals such as Iron and Copper exceeded their maximum permissible guideline values for the protection of human and aquatic health.
