The phytoremediation of metal-contaminated soils offers a low-cost method for soil
remediation and some extracted metals may be recycled for value. Both the phytoextraction …

Ultramafic soils are in equal parts fascinating and dangerous. Developed on rocks derived
predominately from the Earth's mantle and metamorphosed at the ocean floors, ultramafic …

Background Plants that accumulate metal and metalloid trace elements to extraordinarily
high concentrations in their living biomass have inspired much research worldwide during …

Phytomining technology employs hyperaccumulator plants to take up metal in harvestable
plant biomass. Harvesting, drying and incineration of the biomass generates a high-grade …

Nearly 2000 herbarium specimens and 232 species of the genera Homalium and
Hybanthus were analysed for nickel in order to identify plant accumulators of nickel which …

The concentration of any element in dried plant material will usually reflect to some extent
the content of this same element in the underlying substrate. This assumption indeed is the …

Plants growing in metal-enriched substrates take up metals to varying degrees in response
to external and internal factors. The tacit assumption that a plant can thus act as an …

Publisher Summary This chapter discusses the positive-feedback switches in plant
communities. A vegetation positive-feedback switch is a process in which a community …

Sebertia acuminata (Sapotaceae) from New Caledonia has been shown to be a
hyperaccumulator of nickel. The nickel content of the latex (25.74 percent on a dry weight …

Chromium (Cr) is released into the environment through anthropogenic activities and has
gained significant attention in the recent decade as environmental pollution. Its …
