dc.description.abstractIn this study, the effect of different concentrations of lead (0.25, 0.50, 1.00 and 2.00 mM) uptake by roots, on root growth of Allium cepa, and the transport of lead ion (Pb2+), iron ion (Fe2+), manganese ion (Mn2+) and hydrogen ion (H+) were investigated spectrophotometrically. The uptake of Pb2+, Fe2+ and Mn2+ by Allium cepa were monitored by a Unicam model 929 flame atomic absorption spectrophotometer (AAS) and pH values were measured by a Jenway 3040 Ion Analyzer with a combination glass electrode. The mineral content of the solution was measured instead of the mineral content of the root material. Lead ions had inhibitory effect on the root growth in all concentrations during the entire treatment. The EC50 was found at 0.50 mM Pb2+. A large amount of Pb2+ was translocated into A. cepa roots. The kinetics of metal ion transport was described by a pseudo-first order reaction at 1.00 and 2.00 mM metal ion concentrations. Pb2+, Fe2+ and H+ ions transfer into plant from solution but Mn2+ ion transfer to the solution from the plant. The amount of H+ in the solution is increased at all Pb+2 concentrations except 0.25 mM Pb+2 concentration. The results of this study are compared with previous studies with nickel and cadmium treatment.en_US
