Trace metal and metalloid contamination levels in soils and in two native plant species of a former industrial site: Evaluation of the phytostabilization potential

► Soils and plants contamination (metals, metalloids) on a former smelting factory site. ► Identification of specific contaminated zones (slagheaps and horizontal chimney). ► Element transfer into G. alypum and R. officinalis which are metal tolerant species. ► Plant contents more dependent on soil contamination level than on plant species. ► Excluders bioconcentrate metals in roots and offer a phytostabilization potential.
