Technology offer : Phytostabilization of heavy metals in soils

Technology's description

Heavy metals (Cu, Pb, Zn, Cr, Ni, Cd, W, As) are toxic chemicals to humans and the environment. Notably present next to industrial sites, they can scatter in the air, in the water, in the soils and consequently contaminate crops and groundwater next to mine sites.

To struggle against this phenomenon, IRD and Cadi Ayyad University (Marocco) have developed a method to reduce mobility of those metals in contaminated soils.

The technology uses the beneficial effects of mycorrhizae to allow fast growing plants (Eucalyptus spp, casuarinas, jatropha curcas or Australian acacias) which have the ability to decrease the mobility of contaminants in soils.

This innovative and environmentally friendly process is the appropriate solution to overcome the dispersion of heavy metals in the vicinity of contaminated sites.
