dc.description.abstractThis work evaluated environmental metals speciation and the associated health risks using fiveselected edible leafy plants in Amaéchi and Four-Corner dumpsites in Enugu, Enugu State,Nigeria. The soil and plants samples were obtained from Amaéchi and Four-Corner dumpsitesin Enugu and a nearby farm land (control site) and were subjected to standard methods ofchemical analysis. Results obtained showed that mean soil physicochemical parameters andtotal extractable metals were significantly higher (P < 0.05) in the dumpsites compared to controlsite. Carbon:Nitrogen (C:N) ratio was significantly higher (P < 0.05) in the control site compared to that in Amaéchi dumpsite. Sequential extraction showed higher percentages (%) of the nonresidual fraction for all the metals studied except Cu and Cr. The mean order of mobility and bioavailability of the metals were: Pb > Fe > Cd > Zn > Mn > Cr > Ni > Cu. Total mean concentrationof metals in roots, stems and leaves of Amaranthus hybridus, Talinum triangulare, Carica papaya,Ipomea batatas and Luffa aegyptica were significantly higher (P < 0.05) in the dumpsitescompared to control site. The translocation factor, biological concentration factor and biologicalaccumulation coefficient values of the plant species varied for all the metals. The health risks implications of the study were discussed.
