Abstract

DELGADILLO-LOPEZ, Angélica Evelin et al. Phytoremediation: an alternative to eliminate pollution. Trop. subtrop. agroecosyt [online]. 2011, vol.14, n.2, pp.597-612. ISSN 1870-0462.

Phytoremediation consists of a set of technologies that exploit the ability of some plants to absorb, accumulate, metabolize, volatilize or stabilize pollutants that are present in soil, air, water or sediments such as: heavy metals, radioactive metals, organic compounds, and compounds derived from petroleum. Phytoremediation offers numerous advantages in relation to the physicochemical methods that are used nowadays, for example, its wide applicability and low cost. This review provides an overview of the various phytocorrective techniques employed for remediation of polluted soil and water; as well as the potencial that offers the use of transgenic plants.

Keywords : transport; phytotechnologies; transgenic plants; heavy metals; organic pollutants.
