摘要：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.
