Item Determination of cadmium content of water in Ahmadu Bello University Main Campus, Zaria, Nigeria.(Nigerian Journal of Pharmaceutical Sciences. Published by Faculty of Pharmaceutical Sciences, Ahmadu Bello University, Zaria., 2013) Abdullahi, S.T.; Yakasai, I.A.; Garba, M.; Musa, A.; Yakubu, S.I.Cadmium (Cd) is a highly toxic element that is released into the environment from diffuse sources. Contamination of drinking water may occur as a result of the presence of Cd as an impurity in the zinc of galvanized pipes or Cd-containing solders in fittings, water heaters, water coolers and taps or from contaminated raw water sources. In this study, eleven different water samples coded A – L from Ahmadu Bello University main campus Zaria were randomly collected, digested with concentrated nitric acid and analyzed for Cd using Atomic Absorption Spectrophotometer (AAS). The result indicated that the mean concentration of Cd ranged from 0.0864 mg/L to 0.1690 mg/L. The mean concentration of Cd in all the eleven samples were significantly higher than the World Health Organization guideline of 0.0030 mg/L (P<0.05). the Pair-wise correlation studies revealed weak positive relationship (+0.276) between the pH of the drinking water samples and the concentration of Cd. Thus, the batch of water samples analyzed may be hazardous to the health of the University community.Item Determination of lead in potable water of Ahmadu Bello University Main Campus, Zaria, Nigeria.(Biological and Environmental Sciences Journal for the Tropics. Published by Department of Biological Sciences, Faculty of Science, Bayero University, Kano., 2014) Abdullahi, S.T.; Yakasai, I.A.; Garba, M.; Musa, A.; Yakubu, S.I.Lead is one of the most ubiquitous toxic metals of concern in urban water supply systems. It is widely distributed and mobilized in the environment. Human exposure to and uptake of this non-essential element has consequently increased. In this study, five drinking water samples from eleven different locations (A, B, C, D, E, F, G, H, I, J, K and L) and five packaged water samples from Ahmadu Bello University Main Campus, Zaria were randomly collected, digested with concentrated nitric acid using the Association of Official Analytical Chemists nitric acid digestion method and analyzed for lead using Atomic Absorption Spectrophotometer. The results indicated that the mean concentration of lead ranged from 0.0490 ± 0.0133 mg/L to 0.1141 ± 0.0189 mg/L with areas coded D and K having significantly higher concentrations (P<0.05). the mean concentration of lead in all the eleven locations and packaged water were significantly higher than the World Health Organization guidelines of 0.01 mg/L (P<0.05). Consequently, the potable water of Ahmadu Bello Main campus Zaria may pose a threat to the health of the University community.
