Dendroremediation of heavy metal polluted soils

Reviews on Environmental Health
J A González-OrejaCarlos Garbisu

Abstract

Heavy metals are among the most common and harmful pollutants reaching the soil ecosystem all over the world. Phytoextraction is an effective, non-intrusive, inexpensive, aesthetically pleasing, socially accepted, highly promising phytotechnology for the remediation of soils polluted with heavy metals. To overcome the so-called 'Achilles' heel' of phytoextraction, namely, the long time needed for effective remediation, this phytotechnology should be combined with other profit-making activities such as forestry or bioenergy production. Dendroremediation, or the use of trees to clean up polluted soil and water, appears of great potential for metal phytoextraction, especially when using fast-growing tree species, for example, willows (Salix sp. pl.) and poplars (Populus sp. pl.). Most important, the ecologic and environmental risks of dispersing heavy metals into the ecosystems by dendroremediation strategies should be minimized by selecting the right tree species, properly managing/disposing the polluted plant material, or a combination of both options.
