The distribution and concentration of trace elements in K ubanni Reservoir in Zaria (7º38’ and
11º11’) were investigated between November 2002 and April 2004 using Atomic Absorption
Spectrophotometer (AAS). The trace elements detected in the water were Magnesium, Calcium, Iron,
Manganese, Zinc, Chromium, Cobalt, Nickel, Copper, Cadmium and lead. Mean monthly concentrations of
trace elements that ranged from 0.021-1.00mg/L were Cd, Cu, Cr, Zn and Mn. While trace elements that ranged
from 1.22-2.36mg/L were Pb, Ni, Co and Fe. Elements like Zn, Cu, Ni and Pb had higher concentrations in the
dry season than the rainy season. ANOVA showed that there were significant variations between the months,
stations, seasons, months versus stations and seasons versus stations. On the other hand, the concentrations of
Fe, Mn and Cr were significantly higher in the rainy season than the dry season. Water temperature showed
high significant positive correlation with Fe, M n, Cr, Co and Pb (P<0.01). Furthermore, w ater temperature
showed significant negative correlation with Zn and N i (P<0.01). A note worthy observation was the fact that
seven (Fe, M n, Cr, C o, Ni, Cu and Pb) out the nine trace elements determ ined exceeded maximum permissible
concentration for drinking water.
