Stabilization of Soil by Phytoremediation Technique

Abstract

Phytoremediation is the name given to a set of technologies that use different plants as a containment, destruction, or an extraction technique. Phytoremediation as a remediation technology that has been receiving attention lately as the results from field trials indicate a cost savings compared to conventional treatments. The use of plants and associated microorganisms to remove, contain, inactivate, or degrade harmful environmental contaminants (generally termed phytoremediation) and to revitalize contaminated sites is gaining more and more attention. In this review, prerequisites for a successful remediation will be discussed. The performance of phytoremediation as an environmental remediation technology indeed depends on several factors including the extent of soil contamination. Phytoremediation is an emerging and eco-friendly green engineering technology that utilizes the natural properties of plants to remediate contaminated soils, water and sediments. Soil contamination by various inorganic and organic compounds has been a worldwide concern, and phytoremediation has been received increasing attention for remediation of these contaminants. However, the practical application of phytoremediation has been limited because of its low remediation efficiency. This paper addresses phytoremediation on its characteristics, research status, with emphasis on description of its practical application in management and remediation of soil contaminated sites
