Abstract :To investigate the accumulation of lead insert ignore into journalissuearticles values(Pb); by radish insert ignore into journalissuearticles values( Raphanus sativus ); cultivars a study was carried out at Department of Soil and Environmental Sciences, Gomal University, Dera Ismail Khan insert ignore into journalissuearticles values(Pakistan);, during 2012. Two radish varieties i.e., exotic and local, were used. The treatments included sewage water and different concentrations of Pb @ 25, 100, 200 and 400 mg L -1 . The results showed that the total biomass of both the radish varieties were nonsignificantly influenced by the applied Pb concentrations and sewage water, except for root diameter which were significantly greater in the local cultivar insert ignore into journalissuearticles values(3.261 cm);.Pb treatments significantly reduced the growth and yield of both the cultivars. While the Pb uptake by the root and leaf of radish plants was increased by the increasing the applied Pb levels, with the highest value for root insert ignore into journalissuearticles values(19.008 mg kg -1 ); and leaf insert ignore into journalissuearticles values(16.134 mg kg -1 ); in the treatment receiving the highest applied Pb concentrations. The total biomass, fresh weight of root and root diameter was found significantly higher except for Pb @ 400 mg L -1 , in the plants receiving sewage water as compared to the control and different levels of Pb. The interaction amongst the varieties and treatments were found significantly different for various parameters. Thus, it can be concluded, that the use of sewage water and Pb contaminated wastewater results in higher metal concentration in the radish root and may lead to different types of health problems to consumers.
