'hyperaccumulators'
is a term given
to a group of plants whose main characteristics consist of their ability
to 'accumulate', to draw heavy metal residues from the soil. Research
into these plants opens up a number of new possibilities of cleansing
polluted soil.
'superhyperaccumulators'
are improved versions
of the 'hyperaccumulator' plants. Developed jointly with the US, France
and Germany, they represent a major leap in their capacity to draw large
quantities of heavy metals from the soil. The implications of this project
should be understood in terms of time, implying a more realizable, human
scale dimension to the overall duration of a soil-cleansing project.
Today the new breed of plants are all becoming highly guarded,
privately owned 'brands', therefore gaining access to these plants for
research is difficult and costly.
