| dc.description.abstract | Past studies in Kubanni Dam indicated such a high concentration of Pb, that if substantiated pose a danger to the health of the residents of ABU Main Campus, who consume water from Kubanni Dam. But the values obtained from the past studies often contradict each other, that is from 0.5ppm, (Udoh, et. al., 1986)005ppm, (Obamuwe, 1998), and 0.003ppm (Jeb, 1996). This study aims at reassessing the level of Pb concentration in the Kubanni Dam. To ensure the highest possible reliability of results, inter-laboratory and inter-technique comparisons were employed. Whereby same sample was divided into two and given at the same time to two different laboratories that either operate the same technique or different techniques. Laboratories used for this purpose includes; the Department of Geology Ahmadu Bello University Laboratory Zaria, Institute of Chemical Technology Laboratory Basawa, National Animal Production Research Laboratory Shika, Geological Survey Laboratory Kaduna, Nigerian De-fence Academy Laboratory Kaduna and Onarem Research Laboratory, Niger Republic. All these laboratories operate AAS of different models. And lastly, the Center for Energy Research Laboratory A.B.U. Zaria which operates X-ray Fluorescence Technique. The variety of techniques and laboratories employed allow tor the elimination of non credible laboratories. That is, laboratories that gave for the same sample two different results were eliminated, and those that gave results that do not differ, much were accepted as more credible. Findings from both Kubanni Dam and from areas considered as non polluted indicated a Pb concentration in the range of <0.024 to <0.011 ppm for the Kubanni Dam and from <0.014 to <0.()08ppm for non polluted areas, that is at the level of its usual concentration in non polluted water. The first two figures indicate that, there is either no Pb pollution in Kubanni Dam, or in the worst case, there is insignificant Pb pollution, and therefore high values obtained by some of the previous workers cannot stay | en_US |
