dc.description.abstractThe study was undertaken to assessed the accumulation of heavy metals (Cd, Cu, Mn, Ni, Pd and Zn) in riverside soils of River Niger and River Benue around their confluence and their uptake by Amarantus hybridusand Corchorus olitorius L.grown on these soils. Samples were collected in dry and rainy seasons of 2013 and 2014, samples were prepared, digested and taken for AAS analysis. The result shows thatthe concentrations of metals in the soil ranged from3.95-8.4for Cd; 11.6 - 20.2for Cu; 150.3-211.5 for Mn; 177.0 -281.0 forNi; 20.3-34.2 for Pb and 40.5-77.8mg/kg for Zn. Levels of nickel and cadmium were higher than the European Union Standards (2002).The levels of Ni, Zn, Pb and Cd in the vegetableswere higher than the WHO permissible value in plants.The total metal contents in A. hybridus and C. olitorius Lgrown on the riverside soils follow the order: Ni > Mn > Zn > Pb > Cu > Cd. The order of the percentage of extracted metal by EDTA to the total metal content was Pb > Zn > Cu > Ni > Mn > Cd. Geoaccumulation index showed that Cd and Ni were the major pollutants of the soil samples. Of all the metals studied, Pb had the highest bioaccumulation factor, 0.5691 and 0.6301 in the plant for A. hybridus and Corchorus olitorius Lrespectively.en_US
