Abstract
Farming activities and sewage sludge discharge in the Dadin Kowa dam of Gombe state posed serious environmental challenges to the communities. Based on these incidents, investigation was conducted on heavy metal contamination levels from copper (Cu), Managanes (Mn), Lead (Pb), Chromium (Cr), Cobalt (Co), Nickel (Ni), Cadmium (Cd), and Magnesium (Mg) in sediments, water surface , and in three selected fish species (Common cap, African catfish and Tilapia) in the Dadin Kowa dam. Sixteen samples were collected (5 water samples, 8 sediment samples, and 3 fish samples). The means of Cu, Mn, Pb, Cr, Co, Ni, Cd, and Mg in water were 0.110, 0.430, 0.010, not detected (ND), 0.054, ND, 0.072 and 4.395 ppm, respectively. Sediment mean levels were 0.046, 108.670, 0.034, 0.030, 0.055, 0.064, 0.064 and 5.00 ppm. The respectively means of the corresponding heavy metals in the fish were 0.014, 10.787, 0.017, 0.080, 0.03, 0.03, 0.04, and 03.217 ppm. (Mn) mean levels in all the three categories of samples were detected higher than World health organization (WHO) maximum contamination level. Cd in sediment and water samples is also above the WHO maximum level. This assessment offers an opening for continuous monitoring of the environment heavy metals.
