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.

“…Inorganic Hg is one of the environmental pollutants recognised as a highly toxic compound, which is derived from both natural sources and human activities like mining of gold, silver and Hg itself, Cu and Zn mining and smelting or coal burning (Kabata-Pendias and Pendias 2000).

Plants were grown for two weeks and then roots were incubated with increasing Hg concentrations (0 -50 M HgCl 2 ), both at 20ºC and ice-cold temperature. An active, saturable component in Hg uptake was found in oilseed rape and white lupin, with K m and V max values in the range of low affinity transporters for essential micronutrients. A reduction in Hg uptake was observed in the presence of Mn for oilseed rape, suggesting that Hg influx is mediated by a Mn transporter. No effects of Cu on Hg influx were observed for any of the two plant species, suggesting a different transport system for Hg and Cu in roots of oilseed rape and white lupin.

IntroductionElevated concentrations of both essential and nonessential heavy metals in the soil pose a serious environmental problem. Inorganic Hg is one of the environmental pollutants recognised as a highly toxic compound, which is derived from both natural sources and human activities like mining of gold, silver and Hg itself, Cu and Zn mining and smelting or coal burning (Kabata-Pendias and Pendias 2000). Plants are able to take up Hg from the soil or nutrient solution but, generally, absorbed Hg is slightly translocated to shoots because of the low mobility of this heavy metal in plants (Suszcynsky and Shann 1995).Mercury accumulation has been studied in several plant species, like pea and spearmint (Beauford et al. 1977), spring wheat, sugar beet, oil-seed rape, white clover and willow (Greger et al. 2005), rice (Du et al. 2005), tomato (Cho and Park 2000), alfalfa (Ortega-Villasante et al. 2005), lentil, chickpea (Rodríguez et al. 2007) and common vetch (Sierra et al. 2008). In plants, the average Hg concentration ranges from 0.005 to 0.2 mg kg -1 , but it can be much higher in those grown on Hg-contaminated soils (Higueras et al. 2003). The toxicity of Hg results from its effects on the permeability of cell membranes, reactivity with -SH groups of proteins and capability to bind to ATP and thus influence its activity (Patra and Sharma 2000).The determination of the kinetics of metal uptake is a necessary preliminary step for modelling soil-plant transfer in nutrient-poor contaminated environments (Nowack et al., 2006 and Mn 2+ ) were selected to test their influence on Hg uptake. So, the objectives...
