Role of Nanotechnology for Nickel Remediation in Soil and Water

Nickel is naturally occurring in surface water and soil but some actives like industrialization, urbanization, use of chemical fertilizer, pesticides and organic manures increase the nickel concentration. Nickel is not only effect on human health as well as plants. The main toxic symptom produced by nickel is the chlorosis or yellowing of leaves usually followed by necrosis. There are many toxic effects on human health, like embryo toxic effect, allergic reactions, nephrotoxic effects and contact dermatitis due to nickel. The management of nickel contaminated soil and water is a major current environmental issue. Nanotechnology offers a number of emerging techniques much more effective and less costly that could work to immobilize contaminants. In the present study, nanoparticles zero valent iron was used to nickel removal from polluted soil and water.
