Phytoremediation is an emerging technology based on the use of green plants to remove, contain, inactivate or destroy harmful environmental pollutants. Like any othe rnew approach, phytoremediation will only be accepted if its success is demostrated. The key factors are low cost (compared to classical remediation techniques) an daesthetic aspects, making it suitable to remediate large contaminated sites in populated areas. In spite of a growing track record of commercial success, more demostration projects are needed to prove that phytoremediation is effetive, to regiorously measure is underlying economics, and to expand its applications. More fundamental research is also required to better understand the complex interactions between pollutants, soil, plants root and microorganisms at the rhizophere level, to increase the bioavailability of pollutants, to fully exploit th emetabolic diversity of plants and thus, to successfully implement this new green technology. This review is an opinion article, mainly based on the outcomes and questions raised during COST Action 837 (http://lbewww.epfl.ch/COST837) and aims to present European trends and outlook. Recent progress in research and development is highlighted, as needs to treat efficiently both sites and water contaminated by either toxic metals or organic pollutants.
