“…In the last few years many studies have focused on the potential use of trees as a suitable vegetation cover for phytoremediation (French et al, 2006;Jensen et al, 2009). A very suitable tree for use in phytoremediation is willow (Landberg and Greger, 2002).…”

Human activities such as metals mining and milling operations provide one of the most important sources of contamination in the environment. Abandoned mines can be an important source of toxic elements. The threat of heavy metal pollution posed by mine soils generally concerns more than one metal. The aim of this study was to assess total concentration of six potentially toxic metals (Cd, Cr, Cu, Pb, Zn and Fe) in the soil and plant samples of three dominant willow species (Salix purpurea L., Salix caprea L. and Salix eleagnos Scop.) collected from abandoned mixed sulphide mine dumps (Imperina Valley, North-east Italy). Results demonstrate that metal concentrations in soils are in general above the Italian average limits and they are also significantly (except Cr), as compared with controls (p ≤ 0.05), with averages of 2.12 mg Cd kg −1 , 2267 mg Cu kg −1 , 9552 mg Pb kg −1 , 1243 mg Zn kg −1 and 299,973 mg Fe kg −1 . The phytoremediation ability of selected Salix species for heavy metals was estimated. The results have revealed significant differences among willow species (p ≤ 0.05) regardless of the species selected. The transfer factor and bioaccumulation coefficient of selected metals varied among plant species and from different sites. Some of the investigated species have potential for soil stabilization and extraction of heavy metals. The results indicate that there is an increasing need for further research projects mainly focused on the mechanisms whereby such willows are able to survive in contaminated soils.

“…In the humid tropics, the use of organic composts to maintain SOM is widespread (Lasaridi and Stentiford 1998;French et al 2006;Hartley et al 2008), particularly in urban environments where conditions for plant growth are challenging. The benefits of applying organic composted materials to soils are widely acknowledged internationally (Amlinger et al 2007;Lillenberg et al 2010), and it has been found to facilitate increases in organic matter content, biological activity and nutrient supply to plants (Zhang and Selim 2008;Tandy et al 2009).…”

Research relating to the use of organic amendments on soils has focused largely on agricultural soils, and there is a lack of information worldwide on their efficacy as amendments for urban soil management, especially in tropical urban environments. A pot experiment was conducted to assess the influence of biochar and organic compost on urban soil properties and on tree growth performance in Singapore. Biochar and compost were mixed with topsoil in different proportions, and two urban tree species commonly grown in Singapore (Samanea saman and Suregada multiflora) were used. There were significant additional height increments for both the tree species following application of biochar. S. saman exhibited greater stem elongation compared with S. multiflora in response to organic amendments. A significantly higher foliar N content was found in both tree species in biocharamended treatments along with significant increases in P and K. Increases in soil nutrient concentrations were also observed in combined biochar-compost treatments for both species. Combined compost and biochar had the strongest effects on soils and growth of the two urban tree species examined and applications containing biochar resulted in the most significant soil improvements.

Phytoextraction for PTEs may also result in accumulation of organic contaminants in the biomass (e.g., White et al, 2005).…”

The increasing need for biomass for energy and feedstocks, along with the need to divert organic methane generating wastes from landfills, may provide the economic leverage necessary to return this type of marginal land to functional and economic use and is strongly supported by policy at the European Union (EU) level. The use of land to produce biomass for energy production or feedstocks for manufacturing processes (such as plastics and biofuels) has, however, become increasingly contentious, with a number of environmental, economic, and social concerns raised.The REJUVENATE project has developed a decision support framework to help land managers and other decision makers identify potential concerns related to sustainability and what types of biomass reuse for marginal land might be possible, given their particular circumstances. The decision-making framework takes a holistic approach to decision making rather than viewing biomass production simply as an adjunct of a planned phytoremediation project. The framework is serviceable in Germany, Sweden, and the United Kingdom. These countries have substantive differences in their land and biomass reuse circumstances. However, all can make use of the set of common principles of crop, site, value, and project risk management set out by REJUVENATE. This implies that the framework should have wider applicability across the EU. This article introduces the decision support framework. O c 2011 Wiley Periodicals, Inc. INTRODUCTIONThe use of land to produce biomass for energy production or feedstocks for manufacturing processes (such as plastics and biofuels) has become increasingly contentious, with a number of environmental, economic, and social concerns raised. Across Europe there are areas of land that have been damaged by past use. These include brownfields 1 and land affected by contamination. In a large number of situations this land is derelict or underutilized because its restoration is uneconomic or unsustainable using conventional methods. This economically stalled land is described as "marginal land" within this article.There are estimated to be close to one million potential brownfield sites across the European Union (EU; Oliver et al., 2005). The European Environment Agency (EEA) has also collated information regarding the quantity of land contaminated by point sources in Europe. In August 2007, the EEA (EEA, 2007) would require cleanup, with potentially polluting activities having occurred at nearly 3 million sites, and the number of sites was projected to increase. The EEA's report concluded that "although considerable efforts have been made already, it will take decades to clean up a legacy of contamination.""Although considerable efforts have been made already, it will take decades to clean up a legacy of contamination."The extent of diffuse contamination is less well known as evidenced by the European Commission's (EC's) 2010 report, European Environment State and Outlook on Soil (EC, 2010), but appears to be a substantial problem. For example, across tw...
