Enhanced phytoremediation of heavy metal polluted soil with native crops of Punjab, Pakistan
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2016, Vol 8, Issue 4
Abstract
In the present study, chemically and biologically enhanced phytoremediation potentials of maize (Zea mays) and mustard (Brassica campestris) were evaluated by cropping them on two different metals contaminated soils of Lahore and Gujranwala for 75 days. Soils were treated with varying amounts of DTPA (Diethylene Triamine Penta Acetic acid) and three different fungal species to facilitate metal uptake by plants. In pot experiment under green house, addition of fungi and DTPA chelate significantly increased the Cu, Pb, Cr and Cd concentrations in roots and shoots. Maximum maize shoot biomass was obtained in the presence of Aspergillus fumigatus and maximum root biomass was produced in the presence of Aspergillus niger. In case of mustard crop both shoot and root biomass was maximum produced in the presence of Aspergillus fumigatus. It was found that maximum Cd and Cu were solubilized in Aspergillus flavus inoculated soils while Pb and Cr were solubilized maximum in Aspergillus fumigatus inoculated soils in case of maize experiment. In case of mustard maximum Cd and Cu were solubilized in Aspergillus niger inoculated soils while Pb and Cr were solubilized maximum in Aspergillus flavus inoculated soils. Increased metals uptake, bioconcentration factor, and phytoextraction rate and phytoextraction efficiency were noticed over the control in both fungal and DTPA amended soils. Based on obtained data a phytoremdiation model was developed.
