Phytoremediation potential of Brassica juncea L. grown in different Cd and Pb polluted sewage irrigated soils

The current research work is mainly focused on the evaluation of the phytoremediation potential of Brassica juncea L. grown in different sewage irrigated sites in Prayagraj, Uttar Pradesh.The representative soil and plant samples were collected from different sewage irrigated sites in Prayagraj viz., Naini, Preetam Nagar, Daraganj and Rajapur.The heavy metals analyzed plant samples were showed the various concentrations of Cd and Pb ranged from 3.510.16-1.970.09,3.690.25-2.250.12 and 4.780.20-3.110.17,5.130.23-3.060.21mg kg -1 in the roots and shoots respectively.The found results were showed that the maximum accumulation of Pb 5.13 followed by Cd 3.69 mg kg -1 was recorded in the plant shoots at Naini sewage irrigated site.Maximum roots, shoots dry biomass yield was found at Rajapur sewage irrigated site polluted with Cd and Pb ranged from 3.100.07,12.100.51and 3.770.11,12.810.32g plant -1 , respectively.Whereas minimum roots, shoots dry biomass yield i.e., 1.560.03,10.050.32 and 2.090.04,10.480.27g plant -1 was observed from Cd and Pb polluted soils at Naini sewage irrigated site, respectively.The values of BAF and TF of all Cd polluted soil ranged from 1.0630.08-1.3000.06 and 1.0510.10-1.1420.04mg kg -1 , respectively.Whereas the values of BAF and TF of all Pb polluted soils ranged from 1.0750.11-0.9870.03and 1.0730.13-0.9830.07mg kg -1 , respectively.Almost all the values of BAF and TF >1 that proved Brassica juncea L. was a hyperaccumulator plant.Thus, Brassica juncea L. has greater importance in phytoremediation of heavy metal contaminated soils.This research will utilize as phytoremediation of heavy metals contaminated soils and detoxify these natural resources because of it is a cost-effective and green technique which is our future demand to avoid chemical measures.
