Nano-Remediation of Heavy Metals From Polluted Soils

Abstract

Uncontrolled rapidity with anthropogenic activities industrialization have led to significant contamination of soils and streams with accumulated non-biodegradable heavy metals such as arsenic (As), mercurous ion (Hg22+), cadmium (Cd), chromium (Cr), plumbous (Pb4+), and thallium (TI) at intolerable toxic concentrations. This necessitates the remediation of these heavy metals from the environment, as they could mix with different environmental elements, leading to disturbance in the food chain of living organisms. Several experimental studies and technologies have been performed towards the sustainable treatment utilising novel approaches and technologies based on nanotechnology. This chapter addresses the effects and sustainable treatment using nanoparticles in the remediation of heavy metal effected environment
