METHOD FOR PHYTOREMEDIATION OF HEAVY METAL CONTAMINATED SITES

摘要

The invention relates to a method for recovering substrates, mainly mine tailings, using plant species endemic to the location of the substrate to be treated. The substrate recovery method essentially comprises the following steps consisting in: selecting the endemic plant species capable of growing in substrates containing heavy metals; performing a tolerance test on said plant species, finishing with a new selection of the most tolerant species; vegetatively propagating the selected endemic plant species; acclimating the vegetatively propagated species and installing the plant species in the soil of the substrate to be treated. The present method is particularly suitable for use in substrates obtained from tailings, i.e., those containing a high concentration of metals.
