Abstract
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.
