Background information l.jpg
Background Information brownfield sites

  • Use of plants to clean up pollutants in environment

  • Set of technologies that use different plants for techniques

    • Containment, destruction, extraction, transpiration

Goals of this paper l.jpg
Goals of this paper brownfield sites

  • Assess heavy metal phytoextraction performance from alkaline soils

  • Assess the impact of phytoextraction plants on rhizosphere communities


Materials and methods l.jpg
Materials and Methods brownfield sites

  • Soil excavation

    • Alkaline soils contaminated with metals and PAHs

  • Indian mustard, willow, and fescue

    • Chosen because they can extract heavy-metals and grow on the tested soils

  • Pot Trials

    • Chelating agent EDTA


Materials and methods7 l.jpg
Materials and Methods brownfield sites

  • Heavy metal analysis

    • Roots and aerial

  • Microbial enumerations

    • Plate count

  • Community DNA extraction and DGGE

    • 13 samples, characterized diversity

Discussion l.jpg
Discussion brownfield sites

  • Heavy metal accumulations

  • Preferred Harvests

  • Plant mixtures

  • Rhizosphere populations

  • PAH degradation

  • Usefulness of study for projections


Conclusion l.jpg
Conclusion brownfield sites

  • Phytoremediation

    • can offer a feasible alternative for restoration

    • can take a long time with many harvests

    • is an important tool for controlling contaminant migration
