Correlation Analyses of Organically Bound Trace Metals and Sediment in Kubanni, Dam, Zaria, Nigeria

B.W. Tukura, J.A. Kagbu and C.E. Gimba

Abstract:
Surface bed sediments were collected from Kubanni dam during dry and rainy seasons. Concentrations of trace metals bound to carbonates, Fe/Mn-oxides and Organic Matter (OM) were determined using atomic absorption spectrophotometer. Correlations between any two trace metals binding fractions and the correlations between sediment matrices were also determined. Fe/Mn-oxides provided more binding sites for trace metals in dry season (1.64 mg kg-1) and rainy season (1.97 mg kg-1).Correlations analyses show that Cr significantly correlated with Fe/Mn-oxides (r = 0.7971) during rainy season, while Cr and Zn-carbonates (r = 0.8925), Cu and Zn-OM (r = 0.8314) and Pb and Zn-OM (r = 0.7626) in dry season. Significant correlations imply same source of pollution. Correlation analyses of organically bound trace metals and sediment phases show that organically bound Zn in dry season and Cu in rainy season strongly correlated with carbonates and OM, respectively, implying that the predicted amount of these metals are more accurate than those of other organically bound trace metals. The results generally indicate competitions of various sediment phases whenever binding with trace metals do occur. Fe/Mn-oxides and OM are the more accessible to trace metals than other sediment matrices.
