Application of Dendroremediation to the Soil Contaminated Soil by Heavy Metals and Organic Pollutants
Soil contamination by heavy metals and organic pollutants has become a global problem and urgently needs to be solved. Compared with traditional remediation technology of contaminated soils, phytoremediation technology exhibits advantages such as lower cost, easier management, without creating a second pollution and easy acceptance to public,attracting much attention from scientific field. But it also has some deficiencies, for example, low biomass, low growth rate of plants and limited take-up ability of pollutants. With development of phytoremediation technology, woody plant has been applied for phytoremediation, which achieved some successes and showed an excellent application future. The detail about phytoremediation, the achievements and the applying prospects of dendroremediation in phytoremediation of heavy metals and organic matters contamination are described in this paper. Application of woody plant in remediation of contaminated soil would be an important aspect of phytoremediation. To make better use of woody plants to remediation of the contaminated environment in the near future, we should pay more attention to enhancing the basic research on selecting elite dendroremediation materials in the domestic and introducing the elite materials and technologies from other countries,on soil organic pollution and on integrating dendroremediation with other remediation technologies to improve the efficiency of dendroremediation.
