Abstract:

Heavy metals are an increasing ecological threat which commonly result from human activities now a day. A hydroponic study was conducted to assess the effectiveness of maize plant for the remediation of nickle (Ni) and lead (Pb) contaminated water in the absence and presence of ethylene diamine tetra acetic acid (EDTA). Application of Ni and Pb with EDTA reduced the dry weight of shoot (up to 50.5 and 28.5%) and root (up to 23.4 and 14.7%) chlorophyll content (up to 67.7 and 54.6%), and photosynthetic activity (up to 66.7 and 64.9%) respectively, as compared to control. While, maximum concentration of Ni and Pb in shoot and root (up to 15.8 and 17.9 mg kg-1; 11.8 and 17.3 mg kg-1), total accumulation (up to 54.9 and 66.8 mg kg-1), and proline content (up to 111.2 and 101.6%) were recorded in the presence of EDTA respectively, in comparison to control. Generally, it was observed that concentration and total accumulation of Pb was more than Ni in maize plant. It was concluded that the use of synthetic chelator has increased the uptake and translocation of heavy metals in plant biomass that could enhance the phytoremediation of Ni and Pb from contaminated water.
