摘要：The objective of this research was to investigate the chemical fractionation, mobility and bioavailability of Zn in refuse waste soils of some dumpsites in Kaduna metropolis. The metal in the waste soil samples was sequentially extracted and measured using atomic absorption spectrometry, while the total concentration of the metal was determined using Energy Dispersive X-Ray Fluorescence (EDXRF) techniques. The soil pH was also determined. The results showed that Kurmin Mashi (KM) had the highest total concentration of Zn. From the ANOVA (P=0.005<0.05) it was established that there is a significant difference in the total Zn concentrations across the three locations. From the results it was also found out that the metal was distributed between oxide, carbonate and carbonate/organically bound fractions and that EDTA extracted the highest Zn concentration across the dumpsites. Similarly, the ANOVA (p=0.000<0.05) indicated a significant difference in the Zn extracted by the three extraction media.
