Phytoremediation Approaches for Heavy Metal Pollution: A Review
Journal Title: Journal of Plant Science and Research - Year 2015, Vol 2, Issue 2
Abstract
Soil pollution due to heavy metals derived from anthropogenic activities is a major global concern. Detrimental effects of heavy metals on the environment and human health are now well understood. A major challenge is removal and reduction of heavy metal contamination. Of all the remediation techniques available for metal-contaminated soil, phytoremediation is the most cost-effective, environmentally friendly, and practical approach. Phytoremediation includes the removal, relocation, or reduction of contaminants using plants that hyperaccumulate these contaminants. On the basis of the mode of action, phytoremediation is subdivided into subclasses such as phytostabilization, phytofiltration, phytovolatilization, and phytoextraction. In this review, we discuss the need for phytoremediation and its approaches with a special context to the heavy metals.
