Abstract
Analytical studies was carried out on springs water samples collected from Bazza (Michika L.G.A), Pella (Hong L.G.A) and Yadim (Fufore L.G.A) in Adamawa state of Nigeria in order to investigate the occurrence and concentration levels of some heavy metals using the Atomic Absorption Spectrophotometer (AAS).The results obtained revealed that cadmium, chromium and lead were absent in the water samples while Iron, Manganese, Zinc and Copper were found to be present in the water samples with their mean concentration in the following ranges Iron (0.39 – 0.82 mgL־1), Copper (0.05 – 0.20 mgL־1), Manganese (0.01-0.04 mgL־1), and Zinc (0.87-0.94 mgL־1). From the results, Zinc has the highest concentration while Manganese has the least. The values of Cu, Mn, and Zn were found to be within the acceptable range of standard values for heavy metals in water set by NAFDAC [5], SON [6] and WHO [8], While the studied samples contain higher concentration of Fe than the acceptable range of NAFDAC [5] and SON [6].
