Phytomanagement of a metal(loid)-contaminated agricultural site using aromatic and medicinal plants to produce essential oils: analysis of the metal(loid) fate in the value chain.

Phytomanagement uses plants and soil conditioners to create value on contaminated land while minimizing environmental risk. This work was carried out a metal(loid)-contaminated site aimed at assessing the suitability of Salvia sclarea L. (sage) Coriandrum sativum (coriander) combined with an arbuscular mycorrhizal fungus (AMF) inoculant immobilize metal(loid)s produce essential oils (EO). The effect transfer (ML, i.e., Cd, Cu, Pb, Zn, As, Ni, Sb) ML mobility were investigated. concentrations in EO from both plant species valorization options for distillation residues (soil conditioner, animal fodder, anaerobic digestion) studied. Sage suitable candidate this chain because it presents excluder phenotype oil extraction could be used as conditioner. metal sage similar those obtained cultivated uncontaminated soil. These results indicate harvested according fate whole chain. Like sage, coriander did not differ commercial that grown However, use limited by their relatively elevated Cd concentrations. inoculum decrease coriander.
