“…Plants producing oil or biomass for biofuel, essential oils, fibres (e.g. flax, Miscanthus and hemp) and quality hardwood can provide a financial return (Puschenreiter et al 2005;Dickinson 2006;Zehnder 2008;Hartley et al 2009a;Schröder et al 2008a, b;Dickinson et al 2009;Meers et al 2010;Vangronsveld et al 2009;Witters et al 2009). To reduce TE transfer in food crops from agricultural trace element-contaminated soil (TECS), TEinefficient cultivars of major crops and forage plants should be identified and planted (phytoexclusion; Puschenreiter et al 2005;Dickinson et al 2009).…”

Purpose Many agricultural and brownfield soils are polluted and more have become marginalised due to the introduction of new, risk-based legislation. The European Environment Agency estimates that there are at least 250,000 polluted sites in the member states that require urgent remedial action. There is also significant volumes of wastewaters and dredged polluted sediments. Phytotechnologies potentially offer a cost-effective in situ alternative to conventional technologies for remediation of low to mediumcontaminated matrices, e.g. soils, sediments, tailings, solid wastes and waters. For further development, social and commercial acceptance, there is a clear requirement for upto-date information on successes and failures of these technologies based on evidence from the field. This review reports the outcomes from several integrated experimental attempts to address this at both field and market level in the 29 countries participating in COST Action 859. Results and discussion This review offers insight into the deployment of promising and emergent in situ phytotechnologies, for sustainable remediation and management of contaminated soils and water, that integrative research findings produced between 2004 and 2009 by members of COST Action 859. Many phytotechnologies are at the demonstration level, but relatively few have been applied in practice on large sites. They are not capable of solving all problems. Those options that may prove successful at market level are (a) phytoextraction of metals, As and Se from marginally contaminated agricultural soils, (b) phytoexclusion and phytostabilisation of metal-and AsResponsible editor: Stefan Norra M. Mench (*) UMR BIOGECO INRA 1202, Ecologie des Communautés,contaminated soils, (c) rhizodegradation of organic pollutants and (d) rhizofiltration/rhizodegradation and phytodegradation of organics in constructed wetlands. Each incidence of pollution in an environmental compartment is different and successful sustainable management requires the careful integration of all relevant factors, within the limits set by policy, social acceptance and available finances. Many plant stress factors that are not evident in short-term laboratory experiments can limit the effective deployment of phytotechnologies at field level. The current lack of knowledge on physicochemical and biological mechanisms that underpin phytoremediation, the transfer of contaminants to bioavailable fractions within the matrices, the long-term sustainability and decision support mechanisms are highlighted to identify future R&D priorities that will enable potential end-users to identify particular technologies to meet both statutory and financial requirements. Conclusions Multidisciplinary research teams and a meaningful partnership between stakeholders are primary requirements that determine long-term ecological, ecotoxicological, social and financial sustainability of phytotechnologies and to demonstrate their efficiency for the solution of large-scale pollution problems. The gap between research and develop...

“…Many studies have thus been focused on the use of willows and pop lars in phytoextraction (Riddell-Black 1994, Labreque et al 1995, Bañuelos et al 1999, Robinson et al 2000, Aronsson & Perttu 2001, Granel et al 2002, Klang-Westin & Perrtu 2002, Hammer et al 2003, Vyslouz ilová et al 2003, Vervaeke et al 2003, Madejou et al 2004, Sebastiani et al 2004, Kuzovkina et al 2004, Robinson et al 2005, Giachetti & Sebastiani 2006, Dos Santos Ut mazian et al 2007, Jensen et al 2009).

Soil contamination by heavy metals is among the most serious danger for the environment, and new methods for its containment and removal are claimed, in particular for agricultural soils. Phytoremediation is an emerging, potentially effective technology applicable to restoration of contaminated soils and waters. Besides hyperaccumulator herbaceous plants, several woody species are now considered of interest to this aim. Many woody plants are fast growing, have deep roots, produce abundant biomass, are easy to harvest, and several species revealed some capacity to tolerate and accumulate heavy metals. Biotechnologies are now available for investigating this potential and enlarge the possibilities of exploitation of trees for remediation. The use of in vitro cultures, the role of bacteria and mychorrhizas, the powerful tool of genetic engineering, are some of the aspects focused in this paper that open prospects of global relevance for a better understanding of the processes related to the uptake of heavy metals by woody plants. In recent years significant progress has been made in identifying native plants and developing genetically modified tree plants for the remediation of heavy-metal polluted environment. Despite the intensive research developed in the last years, few field trials demonstrated the feasibility of the approach described, therefore much efforts should be addressed to this goal

“…Unfortunately, modern methods of phytoremediation have, to date, not been applied on a large scale, where the bulk of cases use traditional methods for removing pollutants from the soil, which does not involve significant areas (Witters et al 2009(Witters et al , 2012.…”

The objective of this article is a presentation of priority questions and relations involving economic and soil conditions for the application of phytoremediation technology in restoring sustainable development to the environment. The analysis looks at the justifiability of the application of phytoremediation in restoring a balanced environment as an alternative method to costly land recultivation aimed at eliminating pollutants—a solution that is impossible in the case of large areas. The cost effectiveness of the use of phytoremediation in the recovery of trace element in the soil through the process of phytoremediation was demonstrated. The quality of soils as found in the Voivodeship of Łódź was analyzed from the point of view of potential application of the phytoremediation method, taking into account subdivision by heavy metals found in the soils as well as their origins and properties. Grades of soil purity are presented and border values of heavy metal content were identified.
