Elemental Composition Study of leachate in some dumpsites in Bauchi Metropolis

Abstract

Elemental composition study of leachates at four different dumpsites were conducted by analyzing samples of leachates for some heavy metal (cr, cd, pb, and cu ) using complexometric method. The results of analyses showed that the leachate from the four dumpsites have the following ranges of mean concentrations 0.08 – 0.22 mg/dm³ Cd; 0.01 – 0.10 mg/dm³ Cr; 1.81 mg/dm³ Pb; and 1.11 – 1.99 mg/dm³ Cu. These heavy metals are present in the leachates in low amount.   Their presence however suggested that solid waste dumpsite contributes to heavy metals contamination of the environment.
