Phytoremediation
1. Phytoremediation Resource Guide - USEPA (1999)
2. Phytoremediation of TCE in Groundwater by Populus J.Chappell (1997) status report prepared for US EPA. Briefly summarizes the current state of phytoremediation technology, and then focus on the use of poplar trees (Populus sp.) to degrade trichloroethylene (TCE) in groundwater
3. Phytoremediation technologies using trees - a chapter by I.D. Pulford and N.M. Dickinson in the following publication: Trace Elements in the Environment 2005 (Eds. Prassad, M.N.V., and Naidu, R.), CRC Press, New York, pp. 375-395. [ISBN 15 6670 6858]
4. Cadmium uptake in willow and spring wheat in relation to plant growth and Cd concentration in soil solution MSc thesis by Eva Nylund, SLU 2003
5. Growth and trace metal accumulation of two Salix clones on sediment-derived soils with increasing contamination levels. The growth and metal uptake of two willow clones (Salix fragilis 'Belgisch Rood' and Salix viminalis 'Aage') was evaluated in a greenhouse pot experiment with six sediment-derived soils with increasing field Cd levels (0.9–41.4mgkg-1). Metal concentrations of eight elements were measured in roots, stems and leaves and correlated to total and soil water metal concentrations. Willow foliar Cd concentrations were strongly correlated with soil and soil water Cd concentrations. Both clones exhibited high accumulation levels of Cd and Zn in aboveground plant parts, making them suitable subjects for phytoextraction research. Cu, Cr, Pb, Fe, Mn and Ni were found mainly in the roots.
6. Remediation of Sites with Dispersed Radioactive Contamination. This report from the International Atomic Energy Authority examines a variety of technological options for dealing with dispersed low level contamination. The approaches are broadly grouped into the three categories of: (1) Non-intervention; (2) Containment; (3) Removal. The use of willow is discussed in relation tovalorisation and prevention of vertical and horizontal movement of radionuclides.
7. The concept of controlled afforestation of dredged sediment landfills polluted with heavy metals. This paper explores a range of land uses for their suitability for managment of polluted dredged sediments including poplar.
8. Phytotechnology Technical and Regulatory Guidance Document April 2001. Prepared by the Interstate Technology and Regulatory Cooperation Work Group in the USA, the purpose of this document is to provide technical and regulatory guidance to help regulators understand, evaluate, and make informed decisions on phytotechnology proposals. This document includes a description of phytotechnologies, regulatory and policy issues, technical requirements for phytotechnologies, stakeholder concerns, case studies, and technical references.
9. Phytoremediation Decision Tree. The intent of this document is to provide a tool that can be used to determine if phytoremediation has the ability to be effective at a given site. It allows the user to take basic information from a specific site and, through a flowchart layout, decide if phytoremediation is feasible at that site.
