Bioavailability and extraction of heavy metals from contaminated soil by Atriplex halimus

► Evaluation of phytoextraction of metals by Atriplex halimus grown in mine soils. ► Effect of organic amendments on fractionation and bioavailability of metals in soil. ► Organic matter and pH of manure reduced metal bioavailability altering fractionation. ► Manure increased plant growth and total metal accumulation in shoots. ► A. halimus with high biomass and metal accumulation but insufficient phytoextraction.
